INTRODUCTION
79 percent of smartphone owners check their device within 15 minutes of
waking up every morning.[i] Perhaps more startling, fully one-third of

However, industry insiders believe that number is closer to an

Faceit,we’rehooked.
Thetechnologiesweusehaveturnedintocompulsions,ifnotfull-fledgedaddictions. It’s the impulse to check amessage notification. It’s the pull tovisit YouTube, Facebook, or Twitter for just a few minutes, only to findyourselfstill tappingandscrollinganhourlater.It’stheurgeyoulikelyfeelthroughoutyourdaybuthardlynotice.

How do products create habits? The answer: They manufacture them.While fans of the television showMadMen are familiar with how the adindustryoncecreatedconsumerdesireduringMadisonAvenue’sgoldenera,those days are long gone.

Today, small startup teams can profoundly change behavior by guidingusersthroughaseriesofexperiencesIcall“hooks.”Themoreoftenusersrunthroughthesehooks,themorelikelytheyaretoformhabits.

Where could I find the blueprints for forming habits? To mydisappointment, I found no guide. Businesses skilled in behavior designguardedtheirsecretsandalthoughIuncoveredbooks,whitepapers,andblogposts tangentially related to the topic, there was no how-to manual forbuildinghabit-formingproducts.

Theseyearsofdistilledresearchandreal-worldexperienceresultedinthecreation of the HookModel: a four-phase process companies use to formshabits. Through consecutive hook cycles, successful products reach theirultimategoalofunprompteduserengagement,bringingusersbackrepeatedly,withoutdependingoncostlyadvertisingoraggressivemessaging.
While I draw many examples from technology companies given myindustry background, hooks are everywhere — in apps, sports, movies,games,andevenourjobs.Hookscanbefoundinvirtuallyanyexperiencethatburrows intoourminds (andoftenourwallets).The four stepsof theHookModelprovidetheframeworkforthechaptersofthisbook.
TheHookModel
1.Trigger

comeintwotypes:externalandinternal.[viii]
Habit-formingproductsstartbyalertinguserswithexternal triggers likeanemail,awebsite link,or theappicononaphone.

4.Investment
ThelastphaseoftheHookModeliswheretheuserdoesabitofwork.Theinvestment phase increases the odds that the user will make another passthrough the hook cycle in the future. The investment occurswhen the userputs something into the product of service such as time, data, effort, socialcapital,ormoney.
However, the investmentphase isn’t aboutusersopeningup theirwalletsandmovingonwith theirday.Rather, the investment impliesanaction thatimproves the service for the next go-around. Inviting friends, statingpreferences,buildingvirtual assets, and learning tousenew features are allinvestmentsusersmaketoimprovetheirexperience.Thesecommitmentscanbe leveraged tomake the triggermore engaging, the action easier, and therewardmore excitingwith every pass through the hook cycle.Chapter fivedelves into how investments encourage users to cycle through successivehooks.

ANewSuperpower
Habit-forming technology is already here, and it is being used tomold ourlives. The fact thatwe have greater access to theweb through our variousconnected devices— smartphones and tablets, televisions, game consoles,andwearabletechnology—givescompaniesfargreaterabilitytoaffectourbehavior.
Ascompaniescombinetheirincreasedconnectivitytoconsumers,withthe
ability to collect,mine, and process customer data at faster speeds,we arefaced with a future where everything becomes potentially more habit-forming.AsfamedSiliconValleyinvestorPaulGrahamwrites,“…unlesstheforms of technological progress that produced these things are subject todifferentlawsthantechnologicalprogressingeneral,theworldwillgetmore
addictive in the next 40 years than it did in the last 40.”[xiii]
Chapter sixexploresthisnewrealityanddiscussesthemoralityofmanipulation.
Recently,ablogreaderemailedme,“Ifitcan’tbeusedforevil, it’snotasuperpower.” He’s right. And under this definition, building habit-formingproductsisindeedasuperpower.Ifusedirresponsibly,badhabitscanquicklydegenerateintomindlesszombie-likeaddictions.
Did you recognize Barbra and her brother Johnny from the previousexample?Zombiefilmbuffs likelydid.Theyarecharactersfromtheclassichorror flickNight of the LivingDead, a story about people possessed by a
mysteriousforce,whichcompelstheireveryaction.[xiv]
Nodoubtyou’venoticedtheresurgenceofthezombiegenreoverthepastseveral years.Games likeResident Evil, television shows likeTheWalkingDead, andmovies includingWorldWarZ, are a testament to the creatures’growing appeal. But why are zombies suddenly so fascinating? Perhapstechnology’sunstoppableprogress—evermorepervasiveandpersuasive—has grabbed us in a fearful malaise at the thought of being involuntarilycontrolled.
Althoughthefearispalpable,weareliketheheroesineveryzombiefilm—threatenedbutultimatelymorepowerful.Ihavecometolearnthathabit-formingproductscandofarmoregoodthanharm.“Choicearchitecture,”asdescribedbyfamedscholarsThaler,Sunstein,andBalz,offerstechniquestoinfluence people’s decisions and affect behavioral outcomes. Ultimatelythough, the practice should be, “used to help nudge people tomake better
choices (as judged by themselves).”[xv]
Accordingly, this book teachesinnovators how to build products to help people do the things they alreadywanttodobut,forlackofasolution,don’tdo.
Hooked seeks to unleash the tremendous new powers innovators andentrepreneurs have to influence the everyday lives of billions of people. Ibelieve the trinity of access, data, and speed presents unprecedentedopportunitiestocreatepositivehabits.Whenharnessedcorrectly,technologycanenhancelivesthroughhealthfulbehaviorsthatimproveourrelationships,
makeussmarter,andincreaseproductivity.
The Hook Model explains the rationale behind the design of manysuccessful habit-forming products and services we use daily. Although notexhaustivegiventhevastamountofacademicliteratureavailable,themodelis intended to be a practical tool (rather than a theoretical one) made forentrepreneursandinnovatorswhoaimtousehabitsforgood.Inthisbook,Ihave compiled the most relevant research, shared actionable insights, andprovidedapracticalframeworkdesignedtoincreasetheinnovator’soddsofsuccess.
Hooks connect the user’s problem with a company’s solution frequentlyenough to form a habit. My goal is to provide you with a deeperunderstandingofhowcertainproductschangewhatwedo,andbyextension,whoweare.

Theeveningversionofmymorning runhad triggeredabehavioral scriptthat instructedmy body to carry outmy usual, run-related activities— allwithout mindful awareness. Such is the nature of ingrained habits —behaviors done with little or no conscious thought — which by some
estimates,guidenearlyhalfofourdailyactions.[xvii]
Habits are one of the ways the brain learns complex behaviors.Neuroscientists believe habits give us the ability to focus our attention onotherthingsbystoringautomaticresponsesinthebasalganglia,anareaofthe

WhyHabitsareGoodforBusiness
If our programmed behaviors are so influential in guiding our everydayactions, surely harnessing the same power of habits can be a boon forindustry.Indeed,forthoseabletoshapetheminaneffectiveway,habitscanbeverygoodforthebottomline.

However, the frameworkandpracticesexplored in thisbookarenotone-size-fits-all and do not apply to every business or industry. Entrepreneursshould evaluate howuser habits impact their particular businessmodel andgoals.While the viability of some products depends on habit-formation to
thrive,thatisnotalwaysthecase.
For example, companies selling infrequently bought or used products orservicesdonotrequirehabitualusers—atleast,notinthesenseofeverydayengagement. Life insurance companies, for instance, leverage salespeople,advertising, and word-of-mouth referrals and recommendations to promptconsumers tobuypolicies.Oncethepolicyisbought, there isnothingmorethecustomerneedstodo.
In this book, I refer to products in the context of businesses that requireongoing, unprompted user engagement and therefore need to build userhabits. I exclude companies that compel customers to take action throughothermeans.
Before diving into themechanics of how habits aremade,wemust firstunderstandtheirgeneral importanceandcompetitivebenefitsforbusinesses.Habitformationisgoodforbusinessinseveralways.
IncreasingCustomerLifetimeValue

Management’s job, in the eyes ofshareholders, is to implement strategies togrowfutureprofitsby increasingrevenuesordecreasingexpenses.
Fostering consumer habits is an effectiveway to increase the value of acompany by driving higher customer lifetime value (CLTV). CLTV is theamountofmoneymadefromacustomerbeforesheswitchestoacompetitor,stops using the product, or dies. User habits increase how long and howfrequentlycustomersuseaproduct,resultinginhigherCLTV.
SomeproductshaveaveryhighCLTV.Forexample,creditcardcustomerstendtostayloyalforaverylongtimeandareworthabundle.Hence,creditcard companies are willing to spend a considerable amount of moneyacquiring new customers. This explains why you receive so manypromotional offers, ranging from free gifts to airline bonusmiles, to enticeyou to add another cardor upgradeyour current one.YourpotentialCLTVjustifiesacreditcardcompany’smarketinginvestment.
ProvidingPricingFlexibility
RenownedinvestorandBerkshireHathawayCEOWarrenBuffettoncesaid,“You can determine the strength of a business over time by the amount of
agonytheygothroughinraisingprices.”[xx]
Buffettandhispartner,CharlieMunger,realizedthatascustomersformroutinesaroundaproduct,theycometodependupon itandbecome lessprice-sensitive.Theduohavepointed toconsumer psychology as the rationale behind their famed investments in
companies like See’s Candies and Coca-Cola.[xxi]
Buffett and Mungerunderstandthathabitsgivecompaniesgreaterflexibilitytoincreaseprices.

As of December 2013, more than 500 million people have downloadedCandy Crush Saga, a game played mostly on mobile devices. The game’s“freemium” model converts some of those users into paying customers,

SuperchargingGrowth
Users who continually find value in a product aremore likely to tell theirfriends about it. Frequent usage creates more opportunities to encouragepeople to invite their friends,broadcastcontent,andshare throughword-of-mouth. Hooked users become brand evangelists — megaphones for yourcompany,bringinginnewusersatlittleornocost.
Productswithhigheruserengagementalsohavethepotentialtogrowfasterthan their rivals. Case in point: Facebook leapfrogged its competitors,includingMySpace andFriendster, even though itwas relatively late to thesocial networking party. Although its competitors both had healthy growthrates and millions of users by the time Mark Zuckerberg’s fledgling sitelaunched beyond the closed doors of academia, his company came todominatetheindustry.
Facebook’s successwas, in part, a result ofwhat I call themore ismoreprinciple — more frequent usage drives more viral growth. As tech-entrepreneur turned venture capitalist, David Skok points out, “The most
important factor to increasing growth is … Viral Cycle Time.”[xxv]
ViralCycleTimeistheamountoftimeittakesausertoinviteanotheruser,anditcanhaveamassiveimpact.“Forexample,after20dayswithacycletimeoftwodays,youwillhave20,470users,”Skokwrites.“Butifyouhalvedthatcycletimetooneday,youwouldhaveover20millionusers!Itislogicalthatitwouldbebetter tohavemorecyclesoccur,but it is lessobviousjusthowmuchbetter.”
Having a greater proportion of users returning to a service daily,dramatically increases Viral Cycle Time for two reasons: First, daily usersinitiateloopsmoreoften(thinktaggingafriendinaFacebookphoto);second,more daily active users means more people to respond and react to eachinvitation. The cycle not only perpetuates the process — with higher andhigheruserengagement,itacceleratesit.
SharpeningtheCompetitiveEdge
User habits are a competitive advantage. Products that change customerroutinesarelesssusceptibletoattacksfromothercompanies.
Many entrepreneurs fall into the trap of building products that are onlymarginallybetterthanexistingsolutions,hopingtheirinnovationwillbegoodenoughtowoocustomersawayfromexistingproducts.Butwhenitcomestoshakingconsumers’oldhabits,thesenaiveentrepreneursoftenfindthatbetterproducts don’t always win — especially if a large number of users havealreadyadoptedacompetingproduct.
A classic paper by John Gourville, a professor of marketing at HarvardBusinessSchool, stipulates that, “Many innovations fail because consumersirrationally overvalue the old while companies irrationally overvalue the
new.”[xxvi]
Gourvilleclaimsthatfornewentrantstostandachance,theycan’tjustbebetter, they must be nine times better.Why such a high bar? Because oldhabits die hard and new products or services need to offer dramaticimprovements to shake users out of old routines. Gourville writes thatproducts that require a high degree of behavior change are doomed to failevenifthebenefitsofusingthenewproductareclearandsubstantial.
For example, the technology I am using towrite this book is inferior toexistingalternativesinmanyways.I’mreferringtotheQWERTYkeyboardwhich was first developed in the 1870s for the now-ancient typewriter.QWERTY was designed with commonly used characters spaced far apart.This layout prevented typists from jamming the metal typebars of early
machines.[xxvii]
Ofcourse,thisphysicallimitationisananachronisminthedigital age, yet QWERTY keyboards remain the standard despite theinventionoffarbetterlayouts.
ProfessorAugustDvorak’skeyboarddesign,forexample,placedvowelsinthe center row, increasing typing speed and accuracy. Though patented in1932,theDvorakSimplifiedKeyboardwaswrittenoff.
QWERTYsurvivesduetothehighcostsofchanginguserbehavior.Whenfirst introduced to the keyboard, we chicken-peck at the keys one-by-one,usuallywith just a fingeror two.Aftermonthsofpractice,we instinctivelylearn toactivateallour fingers in response toour thoughtswith little tonoconscious effort, and the words begin to flow effortlessly from mind toscreen.Butswitchingtoanunfamiliarkeyboard—evenifmoreefficient—wouldforceustore-learnhowtotype.Fatchance!
Aswewill learn in chapter five, users also increase their dependencyonhabit-forming products by storing value in them — further reducing the
likelihoodofswitching toanalternative.Forexample,everyemailsentandreceivedusingGoogle’sGmail is stored indefinitely,providinguserswithalasting repository of past conversations.New followers on Twitter increaseusers’ clout and amplify their ability to transmit messages to theircommunities.MemoriesandexperiencescapturedonInstagramareaddedtoone’sdigitalscrapbook.Switchingtoanewemailservice,socialnetwork,orphoto-sharing app becomes more difficult the more people use them. Thenon-transferrable value created and stored inside these services discouragesusersfromleaving.
Ultimately,userhabits increaseabusiness’s returnon investment.Highercustomerlifetimevalue,greaterpricingflexibility,superchargedgrowth,anda sharpened competitive edge together equal amore powerful bang for thecompany’sbuck.

BuildingtheMindMonopoly
While user habits are a boon to companies fortunate enough to engenderthem,theirexistenceinherentlymakessuccesslesslikelyfornewinnovationsandstartupstryingtodisruptthestatusquo.Thefactis,successfullychanginglong-termuserhabitsisexceptionallyrare.
Altering behavior requires not only an understanding of how to persuadepeopletoact—forexample,thefirsttimetheylandonawebpage—butalsonecessitatesgettingthemtorepeatbehaviorsforlongperiods,ideallyfortherestoftheirlives.
Companies that succeed in building a habit-forming business are oftenassociated with game-changing, wildly successful innovation. But like anydiscipline, habit design has rules and caveats that define and explain whysomeproductschangeliveswhileothersdonot.
Forone,newbehaviorshaveashorthalf-life,asourmindstendtoreverttoour old ways of thinking and doing. Experiments show that lab animalshabituated to new behaviors tend to regress to their first learned behaviors
overtime.[xxviii]
Toborrowatermfromaccounting,behaviorsareLIFO—“last in, firstout.” Inotherwords, thehabitsyou’vemost recentlyacquiredarealsotheonesmostlikelytogosoonest.
This helps explain the overwhelming evidence that people rarely changetheirhabits for long.Two-thirdsofalcoholicswhocompletea rehabilitation
programwill pick up the bottle, and their old habits, within a year’s time.[xxix]
Researchshowsthatnearlyeveryonewholosesweightonadietgains

Theenemyofformingnewhabitsispastbehaviors,andresearchsuggeststhatoldhabitsdiehard.Evenwhenwechangeourroutines,neuralpathways

Thispresentsanespeciallydifficultchallengeforproductdesignerstryingtocreatenewlinesorbusinessesbasedonformingnewhabits.
Fornewbehaviors to really takehold, theymustoccuroften. In a recentstudyattheUniversityCollegeLondon,researchersfollowedparticipantsas
they attempted to form a habit of flossing their teeth.[xxxii]
As one of itsfindings, the study concluded that the more frequently the new behavioroccurred, thestronger thehabitbecame.Likeflossing, frequentengagementwith a product— especially over a short period of time— increases thelikelihoodofformingnewroutines.
Google Search provides an example of a service built upon a frequentbehavior that helped create users’ habits. If you’re skeptical thatGoogle ishabit-forming(andyouareafrequentGoogleuser),justtryusingBing.Inahead-to-headcomparisonoftheefficacyofanincognitosearch,theproducts
are nearly identical.[xxxiii]
Even if the geniuses at Google have in factperfectedafasteralgorithm,thetimesavedisimperceptibletoeveryonebutrobotsandMisterSpock.Millisecondsmatter,buttheydon’thookusers.
Sowhy haven’tmoreGoogle users switched toBing?Habits keep usersloyal. If a user is familiar with the Google interface, switching to Bingrequires cognitive effort. Although many aspects of Bing are similar toGoogle,evenaslightchangeinpixelplacementforcesthewould-beusertolearnanewwayofinteractingwiththesite.AdaptingtothedifferencesintheBinginterface iswhatactuallyslowsdownregularGoogleusersandmakesBingfeelinferior,notthetechnologyitself.
InternetsearchesoccursofrequentlythatGoogleisabletocementitselfastheoneandonlysolutioninthehabituateduser’smind.Usersnolongerneedto think about whether or not to use Google, they just do. Furthermore,whenever thecompanycan identify theuser through tracking technology, itimproves search results based on past behaviors to deliver amore accurateandpersonalizedexperience,reinforcingtheuser’sconnectionwiththesearch

resultinginGoogle’smarketdomination.[xxxiv]
HabitasStrategy
SometimesabehaviordoesnotoccurasfrequentlyasflossingorGoogling,but it stillbecomesahabit.Foran infrequent action tobecomeahabit, theusermust perceive a high degree of utility, either fromgaining pleasure oravoidingpain.
TakeAmazonasanexample:Thee-tailerhasitssightssetonbecomingtheworld’s one-stop shop. Amazon is so confident in its ability to form userhabits that it sellsand runsads fordirectlycompetitiveproductson its site.[xxxv]
Customersoftenseetheitemtheyareabouttobuylistedatacheaperpriceandcanclickaway to transact elsewhere.To some, this sounds likeaformulafordisaster.ButtoAmazon,itisashrewdbusinessstrategy.
NotonlydoesAmazonmakemoneyfromtheadsitrunsfromcompetingbusinesses,but it alsoutilizesothercompanies’marketingdollars to formahabit in the shopper’s mind. Amazon seeks to become the solution to afrequentlyoccurringpain-point—thecustomer’sdesiretofindtheitemstheywant.

IntheHabitZone
A company can begin to determine its product’s habit-forming potential byplottingtwofactors:frequency(howoftenthebehavioroccurs)andperceivedutility (how useful and rewarding the behavior is in the user’s mind overalternativesolutions).
Googling occurs multiple times per day, but any particular search isnegligiblybetterthanrivalserviceslikeBing.Conversely,usingAmazonmaybea less frequentoccurrence,butusers receivegreatvalueknowing they’ll
findwhatevertheyneedattheoneandonly“everythingstore.”[xxxviii]
As represented in figure1, abehavior thatoccurswithenough frequencyand perceived utility enters the Habit Zone, helping to make it a defaultbehavior.Ifeitherofthesefactorsfallsshortandthebehaviorliesbelowthethreshold,itislesslikelythatthedesiredbehaviorwillbecomeahabit.
Note that the lineslopesdownwardbutneverquite reaches theperceivedutilityaxis.Somebehaviorsneverbecomehabitsbecause theydonotoccurfrequently enough. No matter how much utility is involved, infrequentbehaviors remainconsciousactionsandnevercreate theautomatic responsethat is characteristic of habits. On the other axis however, even a behaviorwhichprovidesminimalperceivedbenefitcanbecomeahabitsimplybecauseitoccursfrequently.

Vitaminsvs.Painkillers
It’s never been easier to launch a new product or service, yet most newendeavors fail.Why?Products fail for a variety of reasons:Companies runoutoffunding,productsentermarketstooearlyortoolate, themarketplacedoesn’tneedwhatcompaniesareoffering,orfounderssimplygiveup.Justasfailurehasmanycauses,successtoocanbeattributedtoavarietyoffactors.However, one thing is common to all successful innovations— they solveproblems.Thatmayseemobvious,butunderstandingthekindofproblemanewproductsolvescanbeatopicofmuchdebate.
“Areyoubuilding a vitaminor painkiller?” is a common, almost clichédquestionmanyinvestorsaskfounderseagertocashtheirfirstventurecapitalcheck. The correct answer, from the perspective of most investors, is thelatter: a painkiller. Likewise, innovators in companies big and small areconstantlyaskedtoprovetheirideaisimportantenoughtomeritthetimeandmoneyneededtobuildit.Gatekeeperssuchasinvestorsandmanagerswantto invest in solving real problems— or, meeting immediate needs — bybackingpainkillers.

vitamins or painkillers?Most people would guess vitamins, thinking usersaren’tdoingmuchofanythingimportantotherthanperhapsseekingaquickboost of social validation. After all, think back to before you first startedusing these services. No one ever woke up in the middle of the nightscreaming,“Ineedsomethingtohelpmeupdatemystatus!”
Butlikesomanyinnovations,wedidnotknowweneededthemuntiltheybecame part of our everyday lives. Before making up your mind on thevitamin or painkiller debate for some of the world’s most successful techcompanies,considerthisidea:Ahabitiswhennotdoinganactioncausesabitofpain.
It is important to clarify that the term “pain,” as it is frequently used inbusinessschoolandmarketingbooks,issomewhathyperbolic.Inreality,theexperiencewe are talking about ismore similar to an “itch,” a feeling thatmanifests within the mind and causes discomfort until it is satisfied. Thehabit-formingproductsweusearesimplytheretoprovidesomesortofrelief.Usingatechnologyorproducttoscratchtheitchprovidesfastersatisfactionthanignoringit.Oncewecometodependonatool,nothingelsewilldo.
My answer to the vitamin or painkiller question is that habit-formingtechnologies are both. These services seem, at first, to be offering nice-to-havevitamins,butoncethehabitisestablished,theyprovideanongoingpainremedy.

An external trigger communicates the next action the user should take.Often,thedesiredactionismadeexplicitlyclear.Forexample,whatexternaltriggersdoyouseeinthisCoca-Colavendingmachineinfigure2?

More choices require the user to evaluate multiple options. Too manychoices or irrelevant options can cause hesitation, confusion, or worse,

Reducing the thinking required to take the next actionincreases the likelihood of the desired behavior occurring unconsciously.We’llexplorethisfurtherinthenextchapter.

TypesofExternalTriggers
Companies can utilize four types of external triggers to move users tocompletedesiredactions:
1.PaidTriggers

Whenaproductbecomestightlycoupledwithathought,anemotion,orapre-existing routine, it leverages an internal trigger.

Connecting internal triggers with aproductisthebrassringofconsumertechnology.
ForYin,theyoungwomanwiththeInstagramhabit,herfavoritephotoappmanufactured a predictable response cued by an internal trigger. Throughrepeated conditioning, a connection was formed between Yin’s need tocapture images of the things around her and the app on her ever-presentmobiledevice.
Emotions, particularly negative ones, are powerful internal triggers andgreatly influence our daily routines. Feelings of boredom, loneliness,frustration, confusion, and indecisiveness often instigate a slight pain orirritation and prompt an almost instantaneous and often mindless action toquellthenegativesensation.Forinstance,YinoftenusesInstagramwhenshefearsaspecialmomentwillbelostforever.

A study at theMissouriUniversity of Science andTechnology illustrates
howtechsolutionscanprovidefrequentpsychologicalrelief.[xlvi]
In2011,agroup of 216 undergraduates volunteered to have their Internet activityanonymously tracked.Over thecourseof theacademicyear, theresearchersmeasured the frequency with which these students used the web and whattheyweredoingonline.
At the end of the study, the researchers compared anonymized data ofstudents who visited the university’s health services to treat symptoms ofdepression. “We identified several features of Internet usage that correlated
withdepression,”wroteSriramChellappan,oneofthestudy’sauthors.[xlvii]
“For example, participants with depressive symptoms tended to engage invery high email usage…Other characteristic features of depressive Internetbehavior included increased amounts of video watching, gaming, andchatting.”
Thestudydemonstratedthatpeoplesufferingfromsymptomsofdepressionused the Internet more. Why is that? One hypothesis is that those withdepression experience negative emotions more frequently than the generalpopulationandseekreliefbyturningtotechnologytolifttheirmood.

Inthepreviouschapter,wecoveredtriggers,sonowlet’sdivedeeperintothe other two components of the Fogg Behavior Model: motivation andability.
Motivation
Whileatriggercuesanaction,motivationdefinesthelevelofdesiretotakethat action.Dr. EdwardDeci, Professor of Psychology at theUniversity ofRochester and a leading researcher on Self-Determination Theory, defines
motivationas,“theenergyforaction.”[lvi]
While thenatureofmotivation isawidelycontested topic inpsychology,FoggarguesthatthreeCoreMotivatorsdriveourdesiretoact.
Foggstatesthatallhumansaremotivatedtoseekpleasureandavoidpain,toseekhopeandavoidfear,andfinally,toseeksocialacceptanceandavoidrejection. The two sides of the threeCoreMotivators can be thought of aslevers to increase or decrease the likelihood of a person taking a particularactionbyincreasingordecreasingtheirmotivation.
MotivationExamplesinAdvertising
Perhapsnoindustrymakestheelementsofmotivationmoreexplicitthantheadvertising business. Advertisers regularly tap into people’s motivations toinfluence theirhabits.By lookingatadswithacriticaleye,wecan identifyhowtheyattempttoinfluenceouractions.
For example, Barack Obama’s 2008 presidential campaign leveraged adeeplyinspiringmessageandimageduringatimeofeconomicandpoliticalupheaval.An iconic poster designed by artist Shepard Fairey conveyed theideaof“hope,”notonlywiththewordprintedinboldlettersalongthebottomof the image, but also through Obama’s steadfast gaze as he lookedconfidentlytowardthefuture.(Unfortunately,theimagewasatthecenterofacopyright battle between Fairey and the Associated Press, which claimedownershipof theoriginalphotographused in theartwork,soI’vechosen to

Of course, this strategy only appeals to a particular demographic’sassociation with sex as a salient motivator.

On the flip-side, negative emotions such as fear can also be powerfulmotivators.The ad in figure 6 shows a disabledmanwith a shockingheadscar. The ad is impactful, communicating the risks of not wearing amotorcycle helmet. The words, “I won’t wear a helmet it makes me lookstupid,” along with the patient’s mental age (post-motorcycle accident) oftwo-yearsold,sendachillingmessage.

InlinewithHauptly’sassertion,asthestepsrequiredtogetsomethingdone(in this case, togetonlineanduse the Internet)were removedor improvedupon,adoptionincreased.
For example, consider the trend-line of the relationship between thepercentageofpeoplecreatingcontentonlineandtheincreasingeaseofdoingso,asshowninfigure7.

Web1.0wascategorizedbyafewcontentproviderslikeC|net(nowcalledCNET) or theNewYork Times publishing to themasses,with only a tinynumberofpeoplecreatingwhatothersread.
Butinthelate1990s,bloggingchangedtheweb.Beforeblogging,amateurwriters had to purchase their owndomain, fiddlewithDNS settings, find awebhost, andsetupacontent-management system topresent theirwriting.Suddenly, new companies like Blogger eliminated most of these steps byallowinguserstosimplyregisteranaccountandstartposting.
Evan Williams, who co-founded Blogger and later Twitter, echoesHauptly’s formula for innovation when he describes his own approach to
building two massively successful companies.[lix]
“Take a human desire,preferably one that has been around for a really long time… Identify that
desireandusemodern technology to takeoutsteps.”Bloggermadepostingcontent online dramatically easier. The result? The percentage of userscreatingcontentonline,asopposedtosimplyconsumingit,increased.
Along came Facebook and other social media tools, refining earlierinnovations such as Bulletin Board Systems (BBS) and Really SimpleSyndication(RSS)feedsintotoolsforstatusupdate-hungryusers.

The pattern of innovation shows that making agiven action easier to accomplish spurs each successive phase of the web,helping to turn the once-niche behavior of content publishing into amainstreamhabit.
Asrecenthistoryofthewebdemonstrates,theeaseordifficultyofdoingaparticular action impacts the likelihood that a behavior will occur. Tosuccessfully simplifyaproduct,wemust removeobstacles that stand in theuser’sway.AccordingtotheFoggBehaviorModel,abilityisthecapacitytodoaparticularbehavior.
***
Fogg describes six “elements of simplicity”— the factors that influence a
task’sdifficulty.[lxi]
Theseare:
-Time-Howlongittakestocompleteanaction.
-Money-Thefiscalcostoftakinganaction.
-PhysicalEffort-Theamountoflaborinvolvedintakingtheaction.
- Brain Cycles - The level of mental effort and focus required to take anaction.
-SocialDeviance-Howacceptedthebehaviorisbyothers.
- Non-Routine - According to Fogg, “How much the action matches ordisruptsexistingroutines.”
Toincreasethelikelihoodofabehavioroccurring,Fogginstructsdesignerstofocus on simplicity as a function of the user’s scarcest resource at thatmoment.Inotherwords,identifywhattheuserismissing.Whatismakingitdifficultfortheusertoaccomplishthedesiredaction?
Is the user short on time? Is the behavior too expensive? Is the userexhaustedafteralongdayofwork?Istheproducttoodifficulttounderstand?Is the user in a social context where the behavior could be perceived asinappropriate? Is the behavior simply so far outside of the user’s normalroutinethatitsstrangenessisoff-putting?
These factorswill differ by person and context, so designers should ask,“Whatisthethingthatismissingthatwouldallowmyuserstoproceedtothenext step?” Designing with an eye toward simplifying the overall userexperiencereducesfriction,removesobstacles,andhelpspushtheuseracrossFogg’sactionline.

Below are examples of simple online interfaces used by a number ofsuccessfulcompanies topromptusers tomovequickly into theHook’snextphase.

Traditionally, registering for anewaccountwith an apporwebsite requiresseveral steps. The user is prompted to enter an email address, create apassword, and submit other information such as a name or phone number.Thisburdenintroducessignificantfriction,detractingusersfromsigning-up.
Mobile devices present the special challenge of smaller screens and slowertypingspeeds.
However,todayitisnearlyimpossibletobrowsetheweboruseamobileapp without encountering a Facebook Login prompt (figure 8). Manycompanies have eliminated several steps in the registration process byenabling users to register with their sites by using their existing Facebookcredentials.

The examples above show how simplicity increases the intended userbehaviors.
MotivationorAbility—WhichShouldYouIncreaseFirst?
After uncovering the triggers that prompt user actions and deciding whichactionsyouwanttoturnintohabits,youcanincreasemotivationandabilityto spark the likelihood of your users taking a desired behavior. But whichshould you invest in first, motivation or ability? Where is your time andmoneybetterspent?
Theanswerisalwaystostartwithability.
Of course, all three parts ofB=MATmust be present for a singular useractiontooccur;withoutacleartriggerandsufficientmotivation,therewillbeno behavior. But for companies building technology solutions, the greatestreturnoninvestmentwillgenerallycomefromincreasingaproduct’sease-of-use.
The fact is, increasing motivation is expensive and time-consuming.Website visitors tend to ignore instructional text. Their attention is split onseveraltasksatonceandtheyhavelittlepatienceforexplanationsaboutwhyorhowtheyshoulddosomething.Instead,influencingbehaviorbyreducingthe effort required to perform an action is more effective than increasing
someone’s desire to do it.Make your product so simple that users alreadyknowhowtouseit,andyou’vegotawinner.
TheEvolutionofTwitter’sHomepage
In 2009, the Twitter homepagewas clutteredwith text and dozens of links(figure14).Thepagewasconfusing,especiallyfornewusersunfamiliarwiththeproduct.Twitter’svaluepropositionofsharingwhatyouweredoingwithfriendsand family failed to resonatewithmostusers,whowondered, “whywouldIwanttobroadcastmyactivities?”Thepagedesigndemandedahighlevelofattentionandcomprehension.

Twitter management knew from early users that thosewho followedotherpeopleon theserviceweremore likely to stayengagedandformahabit.ButsearchingonTwitterwasnothelpingthatgoal,sothecompanydecidedtomakeanotherswitch.
Figure15-TheTwitterhomepagein2010
During the company’s period of hypergrowth, the Twitter homepagebecame radicallymore simple (figure 16). The product description is itselfonly 140 characters long and has evolved from the cognitively difficultrequest that users broadcast their information (as seen in 2009), to the lesstaxing “Find out what’s happening, right now, with the people andorganizationsyoucareabout.”

OnHeuristicsandPerception
So far,we have discussed Fogg’s CoreMotivators and the six elements ofsimplicity as levers for influencing the likelihood of a particular behavioroccurring. These factors echo ideals of how people react when makingrationaldecisions.Forexample,everyEconomics101student learns thataspricesdecrease,consumerspurchasemore—inFogg’sterms,anexampleof
increasingabilitybydecreasingprice.
However,althoughtheprincipleseemselementary,thelaw,likemanyothertheories of human behavior, has exceptions. The field of behavioraleconomics, as studied by luminaries such as Nobel Prize winner DanielKahneman, exposed exceptions to the rational model of human behavior.Eventhenotionthatpeoplealwaysconsumemoreifsomethingcostsless,forexample,isatendency,notanabsolute.

However, more recent research has shown that Olds and Milner’sexperimentswere not stimulating pleasure per se. Stanford Professor BrianKnutson, conducted a study exploring blood flow in the brains of people

The test subjects played agambling gamewhileKnutson and his team looked atwhich areas of theirbrains became more active. The startling results showed that the nucleusaccumbens was not activating when the reward (in this case a monetarypayout)wasreceived,butrather,inanticipationofit.

RewardsoftheTribe,Hunt,andSelf
Inthe1950s,psychologistB.F.Skinnerconductedexperimentstounderstand
how variability impacted animal behavior.[lxxiii]
First, Skinner placedpigeons inside a box rigged to deliver a foodpellet to the birds every timethey pressed a lever. Similar to Olds’ and Milner’s lab mice, the pigeonslearned the cause-and-effect relationship between pressing the lever andreceivingthefood.
In the next part of the experiment, Skinner added variability. Instead ofproviding a pellet every time a pigeon tapped the lever, the machinedischarged foodaftera randomnumberof taps.Sometimes the leverwoulddispense food, sometimesnot.Skinner revealed that the intermittent rewarddramatically increased the number of times the pigeons tapped the lever.Adding variability increased the frequency of the pigeons completing theintendedaction.
Skinner’s pigeons tell us a great deal about what helps drive our ownbehaviors.More recent experiments reveal that variability increases activityinthenucleusaccumbensandspikeslevelsoftheneurotransmitterdopamine,

Rewards of the tribe keepuserscomingback,wantingmore.
Sites that leverage tribal rewards benefit from what psychologist Albert
Banduracalled“sociallearningtheory.”[lxxvi]
Bandurastudiedthepowerof

Inparticular,Bandurashowedthatpeoplewhoobservesomeonebeingrewardedfor a particular behavior are more likely to alter their own beliefs andsubsequentactions.Notably,Banduraalsoshowedthat this techniqueworksparticularly well when people observe the behavior of people most likethemselves,or thosewhoareslightlymoreexperienced(and, therefore, role

StackOverflow
StackOverflow is theworld’s largest question-and-answer site for softwaredevelopers. As with other user-generated content sites such as Quora,Wikipedia, and YouTube, all of Stack Overflow’s content is createdvoluntarily by people who use the site. A staggering 5,000 answers toquestions are generated per day by sitemembers.Many of these responsesprovidedetailed,highly technicalandtime-consuminganswers.Butwhydoso many people spend so much time doing all this work for free? Whatmotivates them to invest the effort into what others may see as theburdensometaskofwritingtechnicaldocumentation?
StackOverflowdevoteeswriteresponsesinanticipationofrewardsofthetribe. Each time a user submits an answer, other members have theopportunity to vote the response up or down. The best responses percolateupwards,accumulatingpointsfortheirauthors(figure22).Whentheyreachcertain point levels,members earn badges, which confer special status andprivileges. Of course, the process of accumulating upvotes (and, therefore,pointsandbadges) ishighlyvariable—nooneknowshowmany theywillreceivefromthecommunitywhenrespondingtoaquestion.

Stack Overflow works because, like all of us, software engineers findsatisfactionincontributingtoacommunitytheycareabout;andtheelement

LeagueofLegends,apopularcomputergame,launchedin2009andquicklyachieved tremendous success.But soon after its launch, the game’s ownersfound they had a serious problem: The online video game was filled with“trolls”—peoplewhoenjoyedbullyingotherplayerswhilebeingprotectedbytheanonymitythegameprovides.Soon,LeagueofLegendsearnedanastyreputation for having an “unforgiving — even abusive —

RewardsoftheHunt
For years, scientists have tried to answer a central question of humanevolution:Howdidearlyhumanshuntforfood?Mostevolutionarybiologistsagree that consuming animalproteinwas a significantmilestone that led tobetter nutrition and, ultimately, bigger brains but the tactical details of the
hunt remain hazy.[lxxx]

One of these groups, the San people of SouthernAfrica,hunt forkudu,a largedeer-likeanimal,usinga technique similar tothe way Lieberman believes humans hunted for the vast majority of ourspecies’ history.

Surprisingly, we even pursue theserewards when we don’t outwardly appear to enjoy them.

ImportantConsiderationsforDesigningRewardSystems
VariableRewardsAreNotaFreePass
InMay2007, a site calledMahalo.comwasborn.A flagship featureof thenew site was a question-and-answer forum known as Mahalo Answers.UnlikepreviousQ&Asites,Mahaloutilizedaspecialincentivetogetuserstoaskandanswerquestions.

ButasMahalostruggledtoretainusers,anotherQ&Asitebegantoboom.Quora,launchedin2010bytwoformerFacebookemployees,quicklygrewinpopularity. Unlike Mahalo, Quora did not offer a single cent to anyoneansweringuserquestions.Why,then,haveusersstayedhighlyengagedwithQuora,butnotwithMahalo,despiteitsvariablemonetaryrewards?
InMahalo’scase,executivesassumedthatpayinguserswoulddriverepeatengagementwiththesite.Afterall,peoplelikemoney,right?Unfortunately,Mahalohadanincompleteunderstandingofitsusers’drivers.

Onlybyunderstandingwhattrulymatterstouserscanacompanycorrectlymatchtherightvariablerewardtotheirintendedbehavior.
Recently, “gamification”— defined as the use of game-like elements innon-gaming environments — has been used with varying success. Points,badges, and leaderboards can prove effective, but only if they scratch theuser’s itch.When there is amismatchbetween the customer’s problemandthe company’s assumed solution, no amount of gamificationwill help spurengagement.Likewise,iftheuserhasnoongoingitchatall—say,noneedtoreturn repeatedly to a site that lacks any value beyond the initial visit —

Variable rewards are not magic fairy dust that a product designer cansprinkleontoaproducttomakeitinstantlymoreattractive.Rewardsmustfitintothenarrativeofwhytheproductisusedandalignwiththeuser’sinternaltriggersandmotivations.
MaintainaSenseofAutonomy
Quorafoundsuccessbyconnectingtherightrewardtotheintendedbehaviorof asking and answering questions. But in August 2012, the companycommitted a very public blunder — one that illustrates another importantconsiderationwhenusingvariablerewards.
Inaneffort to increaseuserengagement,Quora introducedanewfeaturecalled“views,”whichrevealedtherealidentityofpeoplevisitingaparticularquestion or answer. For users, the feedback of knowing who was seeingcontenttheyaddedtothesiteprovedveryintriguing.Userscouldnowknow,for example,whena celebrityorprominentventure capital investorviewedsomethingtheycreated.
However,thefeatureultimatelybackfired.Quoraautomaticallyoptedusersintothenewfeaturewithoutalertingthemthattheirbrowsinghistoryonthesite would be exposed to others. In an instant, users lost their treasuredanonymitywhenasking,answering,orsimplyviewingQuoraquestions that
werepersonal,awkward,orintimate.[xc]
ThemovesparkedauserrevoltandQuorareversedcourseafewweekslater,makingthefeatureexplicitlyopt-in.[xci]
In the case of Quora, the change felt forced and bordered on coercion.While influencing behavior can be a part of good product design, heavy-handedeffortscanhaveadverseconsequencesandrisklosingusers’trust.
We’lladdress themoralityofmanipulation ina laterchapter—butasidefrom the ethical considerations, there is an important point regarding thepsychologicalroleofautonomyandhowitcanimpactuserengagement.
As part of a French study, researchers wanted to know if they couldinfluencehowmuchmoneypeoplehandedtoatotalstrangeraskingforbusfare by using just a few specially encoded words. They discovered a

The turn of phrase has not only proven to increase how much bus farepeoplegive,buthasalsobeeneffectiveinboostingcharitabledonationsandparticipationinvoluntarysurveys.Infact,arecentmeta-analysisof42studiesinvolvingover22,000participantsconcludedthatthesefewwords,placedattheendofarequest,areahighly-effectivewaytogaincompliance,doubling

Whydoesremindingpeopleoftheirfreedomtochoose,asdemonstratedintheFrenchbusfarestudy,provesoeffective?
The researchers believe the phrase “but you are free” disarms ourinstinctive rejectionofbeing toldwhat todo. Ifyouhaveevergrumbledatyourmothertellingyoutoputonacoatorfeltyourbloodpressurerisewhenyourbossmicro-managesyou,youhaveexperiencedwhatpsychologistscall“reactance,”thehair-triggerresponsetothreatstoyourautonomy.
However, when a request is coupled with an affirmation of the right tochoose, reactance is kept at bay. But can the principles of autonomy andreactancecarryoverintothewayproductschangeuserbehavioranddrivetheformationofnewuserhabits?Hereare twoexamples tomake thecase thattheydo,butofcourse,youarefreetomakeupyourmindforyourself.

On the other hand Fitocracy, another health app, approaches behaviorchangeverydifferently.Thegoaloftheappissimilartoitscompetitors—tohelppeopleestablishbetterdietandexerciseroutines.However,itleveragesfamiliarbehaviorsuserswanttodo,insteadofhavetodo.
At first, the Fitocracy experience is similar to other health apps,encouragingnewmemberstotracktheirfoodconsumptionandexercise.ButwhereFitocracydifferentiates itself is in its recognition thatmostuserswillquickly fall off thewagon, just as I hadwithMyFitnessPal, unless the apptapsintoexistingautonomousbehavior.

Perhapsnocompanyinrecentmemoryepitomizesthemercurialnatureofvariable rewards quite like Zynga, makers of the hit Facebook gameFarmVille. In 2009, FarmVille became an unmissable part of the globalzeitgeist. The game smashed records as it quickly reached 83.8 millionmonthly active users by leveraging the Facebook platform to acquire new
players.[xcvii]
In 2010, as “farmers” tended their digital crops — whilepaying real money for virtual goods and levels— the company generated

While Breaking Bad built suspense over time as the audiencewondered how the serieswould end, eventually interest in the showwouldwanewhenitfinallyconcluded.Theseriesenthralledviewerswitheachnewepisode,butnow that it is allover,howmanypeoplewhosaw itoncewillwatchitagain?Withtheplotlinesknownandthecentralmysteriesrevealed,theshowjustwon’tseemasinterestingthesecondtimearound.Perhapstheshowmightresurrectinterestwithanewepisodeinthefuture,butviewershipforoldepisodespeoplehavealreadyseenwillneverpeakasitdidwhentheywerenew.Experienceswith finitevariabilitybecome lessengagingbecausetheyeventuallybecomepredictable.
Businesseswith finitevariabilityarenot inferiorperse, they just operateunderdifferentconstraints.Theymustconstantlychurnoutnewcontentandexperiencestocatertotheirconsumers’insatiabledesirefornovelty.Itisnocoincidence that both Hollywood and the video gaming industry operateunderwhatiscalledthe“studiomodel,”wherebyadeep-pocketedcompany

This is in contrast with companies making products exhibiting “infinitevariability”—experiencesthatmaintainuserinterestbysustainingvariabilitywith use. For example, games played to completion offer finite variabilitywhile those played with others people have higher degrees of infinitevariability because the players themselves alter the game-play throughout.World of Warcraft, the world’s most popular massively multiplayer onlinerole-playinggame,stillcapturestheattentionofmorethan10millionactive

WhileFarmVilleisplayedmostlyin solitude, World of Warcraft is played with teams and it is the hard-to-predictbehaviorofotherpeoplethatkeepsthegameinteresting.
While content consumption, like watching a TV show, is an example offinitevariability,contentcreationisinfinitelyvariable.SiteslikeDribbble,aplatform for designers and artists to showcase their work, exemplify thelonger-lasting engagement that comes from infinite variability. On the site,contributors share theirdesigns in searchof feedback fromother artists.Asnewtrendsanddesignpatternschange,sodoDribbble’spages.ThevarietyofwhatDribbbleuserscancreate is limitless,and theconstantlychangingsitealwaysoffersnewsurprises.

WhichRewardsShouldYouOffer?
Fundamentally, variable reward systems must satisfy users’ needs, whileleaving them wanting to re-engage. The most habit-forming products andservicesutilizeoneormoreofthethreevariablerewardstypesoftribe,huntandself.Infact,manyhabit-formingproductsoffermultiplevariablerewards.
Email, for example, utilizes all three variable reward types. Whatsubconsciously compels us to check our email? First, there is uncertaintysurroundingwhomightbesendingusamessage.Wehaveasocialobligation
to respond to emails and a desire to be seen as agreeable (rewards of thetribe). We may also be curious about what information is in the email.Perhaps something related to our career or business awaits us?

As B.F. Skinner discovered over 50 years ago, variable rewards are apowerful inducement to repeat actions.Understandingwhatmoves users toreturn to habit-forming products gives designers an opportunity to buildproductsthatalignwiththeirinterests.
However, simply giving users what they want is not enough to create ahabit-formingproduct.Thefeedbackloopofthefirstthreestepsofthehook—trigger,actionandvariablereward—stillmissesafinalcriticalphase.Inthenextchapter,wewilllearnhowgettingpeopletoinvesttheirtime,effort,orsocialequityinyourproductisarequirementforrepeatuse.

Ata2010industryconference,JesseSchell,arenownedgamedesignerandprofessor at Carnegie Mellon University, articulated the peculiar train of
thoughtsomeplayersexhibitonline.[cv]
SchellexaminedMafiaWars,oneofZynga’s first breakout hits, which like FarmVille, attracted millions ofplayers.
“There’sdefinitelya lotofpsychologyhere,because ifsomeonehadsaid‘Hey,we’regoingtomakeatext-basedmafiagamethat’sgoingtomakeover$100million,’you’d say, ‘Idon’t thinkyou’lldo that.’Right?”Schell said,channelingthecriticsofthedaywhooriginallydismissedthefree,primarilytext-based online game. But Zynga used its understanding of humanpsychologytobuildanirresistibleproductatthetime.
MafiaWarswasamongthefirstgamestoutilizeinformationaboutplayers’Facebook friends. “It’s not just a virtual world anymore.

Schell went on, “Combine that with the psychological idea … ofrationalization, that anything you spend time on, you start to believe, ‘thismustbeworthwhile.Why?Because I’ve spent timeon it!’And therefore itmustbeworthmekicking in$20because, lookat the timeI’vespenton it.Andnow that I’vekicked in$20, itmustbevaluablebecauseonlyan idiotwouldkickin$20ifitwasn’t.”
Schell’s description of the quirky process of Mafia Wars rationalizationhelpsdemonstratethestrangelogicofhowwechangeourpreferences.Whenplayers contemplate making a purchase, they acknowledge it is unwise tospendmoneyon something that is not good.Andyet, just like the fox thatperceivesthegrapesassourtoreducehisfrustrationatnotbeingabletoreachthem, players justify their purchases to help convince themselves ofsomethingtheywanttobetrue—namely,thattheyarenotfoolish.Theonlysolutionistokeeppayingtokeepplaying.

Unlike in the Action Phase of the Hook discussed in chapter three,investmentsareabouttheanticipationoflonger-termrewards,notimmediategratification.
In Twitter for example, the investment comes in the form of followinganotheruser.There isno immediaterewardforfollowingsomeone,nostarsor badges to affirm the action. Following is an investment in the service,whichincreasesthelikelihoodoftheusercheckingTwitterinthefuture.
Also in contrast to the Action Phase, the Investment Phase increasesfriction. This certainly breaks conventional thinking in the product designcommunity that all user experiences should be as “easy” (and effortless) aspossible.This approach still generally holds true, as doesmy advice in theAction Phase to make the intended actions as simple as possible. In theInvestmentPhase,however,askinguserstodoabitofworkcomesafterusershave received variable rewards, not before. The timing of asking for userinvestment is critically important. By asking for the investment after thereward,thecompanyhasanopportunitytoleverageacentraltraitofhumanbehavior.

The big idea behind the Investment Phase is to leverage the user’sunderstanding that the service will get better with use (and personalinvestment).Likeagoodfriendship, themoreeffortpeopleputin, themorebothpartiesbenefit.

To become better with use, habit-formingtechnologyutilizesinvestmentsusersmakeintheproducttoenhancethe experience. The stored value users put into the product increases thelikelihoodtheywilluseitagaininthefutureandcomesinavarietyofforms.

Pinterest clearly demonstrates the four stages of the Hook Model. It is aseamless flow, from the itch of the internal trigger thatmoves users to theintended action, through the variable reward, and finally to the investment,whichalso loads thenext external trigger.Pinterestusersmove through theHook cycle from beginning to end, and then happily return to the startingpointforanothergo‘round.

The Hook Model is designed to connect the user’s problem with thedesigner’s solution frequentlyenough to formahabit. It isa framework forbuildingproductsthatsolveuserneedsthroughlong-termengagement.
AsuserspassthroughcyclesofTheHookModel,theylearntomeettheirneedswith the habit-formingproduct.Effective hooks transition users fromrelying upon external triggers to cueing mental associations with internaltriggers.Usersmovefromstatesoflowengagementtohighengagementandfromlowpreferencetohighpreference.
You are now equipped to use theHookModel to ask yourself these fivefundamentalquestionsforbuildingeffectivehooks:
1. What do users reallywant?What pain is your product relieving?(InternalTrigger)
2.Whatbringsuserstoyourservice?(ExternalTrigger)
3.Whatisthesimplestactionuserstakeinanticipationofreward,andhow can you simplify your product to make this action easier?(Action)

Whentheywakeup,they check for notifications, tweets, and updates, sometimes even beforesaying “Good morning” to their loved ones. Ian Bogost, the famed gamecreator and professor, calls the wave of habit-forming technologies the“cigaretteofthiscentury”andwarnsoftheirequallyaddictiveandpotentially
destructiveside-effects.[cxv]
Youmaybeasking,“Whenisitwrongtomanipulateusers?”
Manipulation isanexperiencecrafted tochangebehavior—weallknowwhatitfeelslike.We’reuncomfortablewhenwesensesomeoneis tryingtomakeusdosomethingwewouldn’tdootherwise,likewhensittingthroughacarsalesman’sspielorhearingatimesharepresentation.
Yet, manipulation doesn’t always have a negative connotation. If it did,how couldwe explain the numerousmulti-billion-dollar industries that relyheavilyonusersbeingwillinglymanipulated?
Ifmanipulation is an experience crafted to change behavior, thenWeightWatchers,oneof themostsuccessfulmass-manipulationproducts inhistory,
fits the definition.[cxvi]
Weight Watchers customers’ decisions areprogrammedbythedesignerofthesystem.Yet,fewquestionthemoralityofthebusiness.
But what is the difference? Why is manipulating users through flashyadvertisingor addictivevideogames thought tobedistastefulwhile a strictsystem of food rationing is considered laudable? While many people seeWeight Watchers as an acceptable form of user manipulation, our moralcompass has not caught up with what the latest technology now makes
possible.
Ubiquitousaccesstotheweb,transferringgreateramountsofpersonaldataat faster speeds than ever before, has created a more potentially addictiveworld.AccordingtofamedSiliconValleyinvestorPaulGraham,wehaven’t
had time to develop societal “antibodies to addictive new things.”[cxvii]
Grahamplacesresponsibilityontheuser:“Unlesswewanttobecanariesinthe coal mine of each new addiction — the people whose sad examplebecomes a lesson to future generations — we’ll have to figure out forourselveswhattoavoidandhow.”
Butwhat of the peoplewhomake thesemanipulative experiences?Afterall,thecorporationsthatunleashthesehabit-forming,andattimesaddictive,technologies aremadeupof humanbeingswith amoral senseof right andwrong.Theytoohavefamiliesandkidswhoaresusceptibletomanipulation.What shared responsibilities do we growth-hackers and behavior-designershavetoourusers,tofuturegenerations,andtoourselves?
With the increasing pervasiveness and persuasiveness of personaltechnology,someindustryinsidershaveproposedcreatinganethicalcodeof
conduct.[cxviii]
Othersbelievedifferently:ChrisNodder,authorofthebookEvil by Design, writes “… it’s OK to deceive people if it’s in their bestinterests, or if they’ve given implicit consent to be deceived as part of a
persuasivestrategy.”[cxix]
I offer a simple decision support tool entrepreneurs, employees, andinvestors can use long before product is shipped or code is written. TheManipulationMatrix does not try to answerwhich businesses aremoral orwhichwillsucceed,nordoesitdescribewhatcanandcannotbecomeahabit-forming technology.Thematrix seeks tohelpyouanswernot, “Can Ihookmyusers?”butinstead,“ShouldIattemptto?”
To use theManipulationMatrix (figure 36), themaker needs to ask twoquestions. First, “Would I use the product myself?” and second, “Will theproducthelpusersmateriallyimprovetheirlives?”

Remember,thisframeworkisforcreatinghabit-formingproducts,notone-time use goods.Now, let’s explore the types of creatorswho represent thefourquadrantsoftheManipulationMatrix.

However, exactly how Harriman would change the lives of the poorestpeopleintheworldwasnotcleartohimuntilhedecidedtoliveamongthem.In Kenya, he discovered that basic practices ofmodern agriculture— likeproper seed spacing—were still notused.ButHarrimanknew that simplyteachingfarmersnewbehaviorswouldnotbeenough.
Instead,bydrawinguponhisown rural upbringingandexperience livingwith the farmers, Harriman uncovered the obstacles in their way. He soonlearnedthatthelackofaccesstofinancingforhighqualityseedsandfertilizerkeptfarmersfromutilizingyield-boostingtechniques.
Today,NuruisequippingfarmersinKenyaandEthiopia,helpingthemriseout of grinding poverty. It was only by becoming one of his users that
Harrimancoulddesignsolutionstomeettheirneeds.[cxx]
Although it is a long way from Africa to Silicon Valley, the well-documented stories of the founders of Facebook and Twitter reveal theywould likely see themselves asmaking products in the facilitator quadrant.Today, a new breed of companies is creating products to improve lives bycreating healthy habits.Whether getting users to exercise more, creating ahabit of journaling, or improving back posture, these companies are run byauthenticentrepreneurswhodesperatelywanttheirproductstoexist,firstlytosatisfytheirownneeds.
Butwhat if the usage of awell-intended product becomes extreme, evenharmful?Whatabouttheuserswhogobeyondforminghabits,becomingfull-fledgedaddicts?
First, it is important torecognize that thepercentageofuserswhoformadetrimental dependency is very small. Industry estimates for pathologicalusers of even the most habit-forming technologies, such as slot machines
gambling, are just onepercent.[cxxi]
Addiction tends tomanifest in peoplewith a particular psychological profile. However, simply brushing off theissue as too small to matter dismisses the very real problems caused bytechnologyaddiction.
For the first time, however, companies have access to data that could beused to flag which users are using their products too much. Whethercompanies choose to act on that data in a way that aids their users is, ofcourse, a question of corporate responsibility. Companies building habit-formingtechnologieshaveamoralobligation—andperhapssomedayalegalmandate — to inform and protect users who are forming unhealthyattachments to their products. It would behoove entrepreneurs buildingpotentially addictive products to set guidelines for identifying and helpingaddictedusers.
However, for the overwhelmingmajority of users, addiction to a productwill never be a problem. Even though theworld is becoming a potentiallymore addictive place, most people have the ability to self-regulate theirbehaviors.
The role of facilitator fulfills the moral obligation for entrepreneursbuildingaproducttheywilluse,andwhichtheybelievemateriallyimprovesthe livesofothers.As longas theyhaveprocedures inplace toassist thosewhoformunhealthyaddictions,thedesignercanactwithacleanconscience.TotakelibertieswithMahatmaGandhi’sfamousquote,facilitators“buildthechangetheywanttoseeintheworld.”
ThePeddler
Headyaltruisticambitionscanat timesoutpace reality.Toooften,designersofmanipulativetechnologyhaveastrongmotivationtoimprovethelivesoftheir users, butwhen pressed, they admit theywould not actually use theirown creations.

Countless companies convince themselves they’re making ad campaignsuserswilllove.Theyexpecttheirvideostogoviralandtheirbrandedappsto
be used daily. Their so-called “reality distortion fields” keep them from
asking the critical question, “Would I actually find this useful?”[cxxii]
Theanswer to this uncomfortable question is nearly always “No,” so they twisttheir thinking until they can imagine a user they believemight find the advaluable.
Materiallyimprovingusers’livesisatallorder,andattemptingtocreateapersuasivetechnologythatyoudonotuseyourselfisincrediblydifficult.Thisputsdesignersataheavydisadvantagebecauseoftheirdisconnectwiththeirproducts and users. There’s nothing immoral about peddling; in fact,manycompanies working on solutions for others do so out of purely altruisticreasons.

TheEntertainer
Sometimesproduct-makersjustwanttohavefun.Ifcreatorsofapotentiallyaddictive technology make something that they use but can’t in goodconscienceclaimimprovesusers’lives,they’remakingentertainment.
Entertainment is art and is important for its own sake. Art provides joy,helpsusseetheworlddifferently,andconnectsuswiththehumancondition.These are all important and age-old pursuits.

TheDealer
Creating a product that the designer does not believe improves users’ livesand that he himselfwould not use is called exploitation. In the absence ofthesetwocriteria,presumablytheonlyreasonthedesignerishookingusersisto make a buck. Certainly there is money to be made addicting users tobehaviorsthatdolittlemorethanextractcash;andwherethereiscash,therewillbesomeonewillingtotakeit.
Thequestionis:Isthatsomeoneyou?Casinosanddrugdealersofferusersagoodtime,butwhentheaddictiontakeshold,thefunstops.
InasatiricaltakeonZynga’sFarmVillefranchise,IanBogostcreatedCowClicker, a Facebook app where users did nothing but incessantly click on
virtualcowstohearasatisfying“moo.”[cxxiii]
Bogost intended to lampoonFarmVille by blatantly implementing the same game mechanics and viralhacks he thoughtwould be laughably obvious to users. But after the app’susage exploded and some people became frighteningly obsessed with thegame, Bogost shut it down, bringing on what he called “The
Cowpocalypse.”[cxxiv]
Bogost rightfully compared addictive technology to cigarettes. Certainly,theincessantneedforasmokeinwhatwasonceamajorityoftheadultU.S.population has been replaced by a nearly equal compulsion to constantlycheck our devices. But unlike the addiction to nicotine, new technologiesoffer an opportunity to dramatically improve users’ lives. Like alltechnologies, recent advances in the habit-forming potential of digitalinnovationhavebothpositiveandnegativeeffects.
But if the innovator has a clear conscience that the product materiallyimprovespeople’slives—firstamongthem,thedesigner’s—thentheonlypathistopushforward.Withtheexceptionoftheaddictedonepercent,usersbearultimateresponsibilityfortheiractions.
However,as themarchof technologymakes theworldapotentiallymoreaddictive place, innovators need to consider their role. It will be years,

For now, users must learn to assess these yet-unknownconsequencesforthemselves,whilecreatorswillhavetolivewiththemoralrepercussionsofhowtheyspendtheirprofessionallives.

“Unlikeother companies,whenwe started,wewerenotbuildingaBiblereader for seminary students.

That’s when Gruenewald says he implemented a plan— actually, manyplans.AsignatureoftheBibleappisitsselectionofover400readingplans—adevotional iTunesof sorts, catering to anaudiencewithdiverse tastes,troubles, and tongues. Given my personal interest and research into habit-formingtechnology,IdecidedtostartaBiblereadingplanofmyown.Aplantitled“Addictions”seemedappropriate.
For thosewho have yet to form a routine aroundBiblical study, readingplans provide structure and guidance. “Certain sections of theBible can bedifficultforpeopletogetthrough,”Gruenewaldadmits.“Byofferingreadingplans with different small sections of the Bible each day, it helps keep[readers]fromgivingup.”

By identifying where your technology is lacking, you can focus ondevelopingimprovementstoyourproductwhereitmattersmost.
HabitTesting
By following the “DoThisNow” sections inprevious chapters, you shouldhave enough knowledge to prototype your product. But simply coming upwith ideas is not enough, and creating user habits is often easier said thandone. The process of developing successful habit-forming technologiesrequirespatienceandpersistence.TheHookModelcanbeahelpfultoolforfiltering out bad ideaswith low habit potential aswell as a framework foridentifying room for improvement in existing products. However, after thedesignerhasformulatednewhypotheses,thereisnowaytoknowwhichideaswillworkwithouttestingthemwithactualusers.
Buildingahabit-formingproduct isan iterativeprocessand requiresuserbehavior analysis andcontinuous experimentation.Howcanyou implementthe concepts in this book to measure your product’s effectiveness buildinguserhabits?
Through my studies and discussions with entrepreneurs at today’s mostsuccessfulhabit-formingcompanies,I’vedistilledthisprocessintowhatIcall“Habit Testing.” It is a process inspired by the build-measure-learn
methodologychampionedbytheleanstartupmovement.HabitTestingoffersinsightsandactionabledatatoinformthedesignofhabit-formingproducts.Ithelps clarify who your devotees are, what parts of your product are habit-forming (if any), andwhy those aspects of your product are changing userbehavior.
Habit Testing does not always require a live product; however, it can bedifficult to draw clear conclusions without a comprehensive view of howpeople are using your system. The following steps assume you have aproduct,users,andmeaningfuldatatoexplore.
Step1:Identify
The initial question for Habit Testing is “Who are the product’s habitualusers?”Remember,themorefrequentlyyourproductisused,themorelikelyitistoformauserhabit.
First,definewhat itmeans tobeadevoteduser.Howoften“should”oneuse your product? The answer to this question is very important and canwidelychangeyourperspective.Publiclyavailabledatafromsimilarproductsorsolutionscanhelpdefineyourusersandengagementtargets.Ifdataisnotavailable,educatedassumptionsmustbemade—butberealisticandhonest.
IfyouarebuildingasocialnetworkingapplikeTwitterorInstagram,youshouldexpecthabitualuserstovisittheservicemultipletimesperday.Ontheotherhand,youshouldnotexpectusersofamovierecommendationsitelikeRottenTomatoes tovisitmore thanonceor twiceaweek (since theirvisitswillcomeontheheelsofseeingamovieorresearchingonetowatch).Don’tcome up with an overly aggressive prediction that only accounts for uber-users;youarelookingforarealisticguesstocalibratehowoftentypicaluserswillinteractwithyourproduct.
Once you know how often users should use your product, dig into thenumbersandidentifyhowmanyandwhichtypeofusersmeetthisthreshold.Asabestpractice,usecohort analysis tomeasurechanges inuserbehaviorthroughfutureproductiterations.
Step2:Codify
Hopefully you’ve identified a few users who meet the criteria of habitualusers. But howmany users are enough?My rule of thumb is five percent.Thoughyourrateofactiveuserswillneedtobemuchhighertosustainyour
business,thisisagoodinitialbenchmark.
However, if at least five percent of your users don’t find your productvaluableenoughtouseasmuchasyoupredictedtheywould,youmayhaveaproblem.Eitheryou identified thewrongusersoryourproductneeds togobackto thedrawingboard.But ifyouhaveexceededthatbarandidentifiedyourhabitualusers, thenextstepistocodifythestepstheytookusingyourproducttounderstandwhathookedthem.
Userswillinteractwithyourproductinslightlydifferentways.Evenifyouhaveastandarduserflow,thewayusersengagewithyourproductcreatesaunique fingerprint. Where users are coming from, decisions made whenregistering,andthenumberoffriendsusingtheservice,arejustafewofthebehaviors that help create a recognizable pattern. Sift through the data todetermine if similarities emerge. You’re looking for a “Habit Path,” — aseriesofsimilaractionssharedbyyourmostloyalusers.
For example, in its early days, Twitter discovered that once new usersfollowed 30 other members, they hit a tipping point which dramatically
increasedtheoddstheywouldkeepusingthesite.[cxxx]
Everyproducthasadifferentsetofactionsthatdevoteduserstake;thegoalof finding theHabitPath is todeterminewhichof thesesteps iscritical forcreating devoted users so that you canmodify the experience to encouragethisbehavior.
Step3:Modify

DiscoveringHabit-formingOpportunities
TheHabitTestingprocess requires theproductdesigner tohaveanexisting
product to test.Butwheremight you look to findpotentially habit-formingexperiencesripefornewtechnologicalsolutions?
Whenitcomestodevelopingnewproducts,therearenoguarantees.Alongwith creating an engaging product as described in this book, startupsmustalso find a way tomonetize and grow.Although this book does not coverbusiness models for delivering customer value or methods for profitablecustomer acquisition, both are necessary components of any successfulbusiness. Several thingsmust go right for a new company to succeed, andforminguserhabitsisjustoneofthem.
As we saw in chapter six, being a “facilitator” is not only a moralimperative, it alsomakes forbetterbusinessespractices.Creating aproductthe designer uses and believesmaterially improves people’s lives increasestheoddsofdelivering somethingpeoplewant.Therefore, the firstplace forthe entrepreneur or designer to look for new opportunities is in themirror.PaulGrahamadvisesentrepreneurstoleavethesexy-soundingbusinessideasbehind and instead build for their own needs: “Instead of asking ‘whatproblemshould I solve?’ ask ‘whatproblemdo Iwish someoneelsewould

Bufferwas founded in2010and isnowusedbyover1.1millionpeople.[cxxxii]
Itsfounder,JoelGascoigne,describedthecompany’sinceptioninan
interview.[cxxxiii]
“The idea for Buffer came tome after I had been usingTwitter for about 1.5 years. I had started to share links to blog posts andquotesIfoundinspiring,andIfoundthatmyfollowersseemedtoreallylikethese types of tweets. I would often get retweets or end up having a greatconversationaroundtheblogpostorquote.That’swhenIdecidedIwantedtoshare this kindof contentmore frequently, because the conversationsbeingtriggered were allowing me to be in touch with some super smart andinterestingpeople.”
Gascoigne continues, “So, withmy goal of sharingmore blog posts andquotes,Istartedtodoitmanually.Iquicklyrealizedthatitwouldbefarmoreefficient to schedule these tweets for the future, so I started to use a fewavailableTwitter clients to do this. The key pain I ran into herewas that I

NascentBehaviors
Sometimes technologies that appear to cater to a niche will cross into themainstream.Behaviorsthatstartwithasmallgroupofuserscanexpandtoawider population, but only if they cater to a broad need.However, the factthatthetechnologyisatfirstusedonlybyasmallpopulationoftendeceivesobserversintodismissingtheproduct’struepotential.
Astrikingnumberofworld-changinginnovationswerewrittenoffasmerenovelties with limited commercial appeal. George Eastman’s Browniecamera, preloaded with a film roll and selling for just $1, was originally
marketedasachild’s toy.[cxxxiv]
Establishedstudiophotographers saw thedeviceaslittlemorethanacheapplaything.
The invention of the telephone was also dismissed at first. Sir WilliamPreece,thechiefengineeroftheBritishPostOfficefamouslydeclared,“TheAmericans have need of the telephone, but we do not.We have plenty of
messengerboys.”[cxxxv]
In 1911, Ferdinand Foch the future Commander-in-Chief of the AlliedArmies in WWI said, “Airplanes are interesting toys but of no military
value.”[cxxxvi]
In1957,theeditorofbusinessbooksforPrenticeHalltoldhispublisher,“Ihavetraveledthelengthandbreadthofthiscountryandtalkedwiththebestpeople,andIcanassureyouthatdataprocessingisafadthatwon’tlastouttheyear.”
TheInternetitself,andeachsuccessivewaveofinnovation,hascontinuallyreceivedcriticismforitsinabilitytogainmassappeal.In1995,CliffordStollwrote aNewsweek article titled, “The Internet? Bah!” where he declared,“The truth isnoonlinedatabasewill replaceyourdailynewspaper…”Stollcontinued, “…we’ll soon buy books and newspapers straight over the
Internet.Uh,sure.”[cxxxvii]
But of course, nowwe do read books and newspapers over the Internet.When technologies are new, people are often skeptical.Old habits die hardandfewpeoplehavetheforesighttoseehownewinnovationswilleventuallychange their routines. However, by looking to early adopters who havealreadydevelopednascentbehaviors,entrepreneursanddesignerscanidentifynicheusecases,whichcanbetakenmainstream.
For example, in its early days, Facebook was only used by Harvardstudents. The service mimicked an offline behavior familiar to all collegestudents at the time: Perusing a printed book of student faces and profiles.AfterfindingpopularityatHarvard,FacebookrolledouttootherIvyLeagueschools,andthen,tocollegestudentsnationwide.Nextcamehighschoolkidsand later, employees at select companies. Finally, in September of 2006,Facebookwasopenedtotheworld.Today,Facebookisusedbyoverabillionpeople.Whatfirstbeganasanascentbehavioratonecampusbecameaglobalphenomenon catering to the fundamental human need for connection toothers.
Asdiscussedearlyinthebook,manyhabit-formingtechnologiesbeginas“vitamins” — nice-to-have products that, over time, become must-have“painkillers” by relieving an itch or pain. It is revealing that so manybreakthroughtechnologiesandcompanies,fromairplanestoAirbnb,wereatfirst dismissed by critics as toys or niche markets. Looking for nascentbehaviors among early adopters can often uncover valuable new businessopportunities.
EnablingTechnologies
MikeMaples,Jr.,aSiliconValley“superangel”investor,likenstechnologytobig-wavesurfing.In2012,Maplesblogged,“Inmyexperience,everydecadeorso,weseeamajornewtechwave.WhenIwasinhighschool,itwasthePC revolution. I made my career as an entrepreneur at the end of theclient/serverwaveandintheearlyphasesoftheInternetwave.Today,weareatthemassadoptionphaseofthesocialnetworkingwave.Iamobsessedwiththese technology waves and have spent a lot of time studying how theydevelopandwhatpatternscanbeobserved.”
Maplesbelievestechnologywavesfollowathree-phasepattern,“Theystartwithinfrastructure.Advancesininfrastructurearethepreliminaryforcesthatenable a large wave to gather. As the wave begins to gather, enablingtechnologiesandplatformscreatethebasisfornewtypesofapplicationsthatcause a gathering wave to achieve massive penetration and customeradoption.Eventually,thesewavescrestandsubside,makingwayforthenext
gatheringwavetotakeshape.”[cxxxviii]
Entrepreneurs looking for windows of opportunity would be wise toconsider Maples’ metaphor. Wherever new technologies suddenly make abehavioreasier,newpossibilitiesareborn.Oftentimes,thecreationofanewinfrastructure opens up unforeseen ways to make other actions simpler ormorerewarding.Forexample,theInternetwasfirstmadepossiblebecauseoftheinfrastructurecommissionedbytheUnitedStatesgovernmentduringtheColdWar. Then, enabling technologies such as dial-upmodems, and later,high-speed Internet connections, provided access to the web. And finally,HTML,webbrowsers and search engines— the application layer—madebrowsing possible on the World Wide Web. At each successive stage,previous enabling technologies allowed new behaviors and businesses toflourish.
IdentifyingareaswhereanewtechnologymakescyclingthroughtheHookModel faster,more frequent, ormore rewarding provides fertile ground fordevelopingnewhabit-formingproducts.
InterfaceChange
Technological changes often create opportunities to build new hooks.However, sometimes no technology change is required. Many companies
have found success in driving new habit formation by identifying howchanginguserinteractionscancreatenewroutines.
Whenever a massive change occurs in the way people interact withtechnology,expecttofindplentyofopportunitiesripeforharvesting.Changesininterfacesuddenlymakeallsortsofbehaviorseasier.Subsequently,whentheeffortrequiredtoaccomplishanactiondecreases,usagetendstoexplode.
A long history of technology businessesmade their fortunes discoveringbehavioral secretsmadevisiblebecauseof a change in the interface.Appleand Microsoft succeeded by turning clunky terminals into graphical userinterfacesaccessiblebymainstreamconsumers.Googlesimplifiedthesearchinterface as compared to those of ad-heavy and difficult-to-use competitorssuch as Yahoo! and Lycos. Facebook and Twitter turned new behavioralinsightsintointerfacesthatsimplifiedsocialinteractionsonline.Ineachcase,anewinterfacemadeanactioneasieranduncoveredsurprisingtruthsaboutuserbehaviors.
More recently, Instagram and Pinterest have capitalized on behavioralinsightsbroughtaboutbyinterfacechanges.Pinterest’sabilitytocreatearichcanvasofimages—utilizingwhatwerethencutting-edgeinterfacechanges—revealednewinsightsabouttheaddictivenatureofanonlinecatalog.ForInstagram, the interface change was cameras integrated into smartphones.Instagram discovered that its low-tech filters made relatively poor-qualitysmartphonephotoslookgreat.Suddenlytakinggoodpictureswithyourphonewas easier and Instagram used its newly discovered insights to recruit anarmyofrabidlysnappingusers.WithbothPinterestandInstagram,tinyteamsgenerated huge value— not by cracking hard technical challenges, but bysolving common interaction problems. Likewise, the fast ascent of mobiledevices,includingtablets,hasspawnedanewrevolutionininterfacechanges— and a new generation of startup products and services designed aroundmobileuserneedsandbehaviors.
To uncover where interfaces are changing, Paul Buchheit, Partner at Y-
Combinator, encourages entrepreneurs to “live in the future.”[cxxxix]
Aprofusion of interface changes are just a few years away. Wearabletechnologies likeGoogleGlass, theOculusRift virtual reality goggles, andthe Pebble watch promise to change how users interact with the real anddigitalworlds.Bylookingforwardtoanticipatewhereinterfaceswillchange,theenterprisingdesignercanuncovernewwaystoformuserhabits.
