Forecasting - last lecture

● TETLOCK P. (2005): People who make predictions regarding their business are no better than the rest of us → experts with great knowledge are likely to be less reliable in terms of forecasts than non-specialists

● Cynefin approach (SNOWDEN, BOONE 2007): a sense-making model organized around 4 systems (simple, complicated, complex, chaotic) enhancing every situation requires a specific reaction

● Adaptive Management (ALLEN et al. 2013) has similarities with the Cynefin model and

highlights the relevance of the amount of control on the situation (Uncorroborated, Trial and error, Step-wise, Horse race). People must admit their lack of knowledge and recognize that much of what they know is wrong

The Black Swan by Taleb – Overview

4

When all swans were white - common pattern - extraordinary becomes common

The Narrative Fallacy - “ confirmation bias” - “tunneling” - past creates the present

“Mediocristan” vs “Extremistan” - smooth away the rough features of reality

Phony Forecasting (Nerds and Herds) - “secret” of predicting outliers

N.N. Taleb (2007) The Black Swan, The Impact of the Highly Improbable

Impact on forecasting in management

Black Swans are unpredictable. People continue see patterns in misleading data.

Positive Black Swans Negative Black Swans

Do not look/ignore “Experts” tend to have bias

Underappreciated Hedge against them

Know in many cases you cannot be sure

Avoid dogmatism - avoid nerds and herds (phony forecasting)

Look for nonobvious

Understand where you can be fooled

N.N. Taleb (2007) The Black Swan, The Impact of the Highly Improbable

Page 6: Managing in an Age of Transitions - Scopes of Forecasting

Example: Are you good or bad forecasters? Bazerman (1984)

A firm expects to lay-off 6,000 employees in one year. Which plan would you choose as main manager of the department?

1st scenario

Gain scenario (opportunity) → risk aversion

Plan A: This plan will save 2,000 jobs

Plan B: This plan has a ⅓ probability of saving all 6,000 jobs, but a ⅔ probability of saving no jobs

2nd scenario

Loss scenario (threat) → risk seeking

Plan A: This plan will loose 4,000 jobs

Plan B: This plan has a ⅓ probability of no-one losing their job, but a ⅔ probability that 6,000 employees will lose their jobs

6

>80%

<20%

<20%

>80%

Scenario 1 Scenario 2

Plan A Save 2,000 jobs = Lose 4,000 jobs

Plan B ⅓ save 6,000 jobs⅔ save no jobs

= ⅓ lose no jobs= ⅔ lose 6,000 jobs

The firms expects a loss of 6,000 jobs. Problem simplified

The outcomes of both Plan A are the sameThe outcomes of both Plan B are the same

The 4 Quadrants by Zeisberger & Munro - Overview

8

A decision-making model applied to risk management. It classifies risks regarding the nature of the risks (normal or indeterminate) and their potential payoffs (simple or complex) in order to better understand risks and better manage it (=better forecast it).

Impact on forecasting in management

13Zeisberger C., Munro D. (2010), “The 4 Quadrants”: A World of Risk and a Road Map to Understand It

The 4 Quadrants The Cynefin Model (SNOWDEN, BOONE 2007)

Q1 No outliers or surprises - No need of risk managers in that environment - Forecasts are easy

Q2 Define the risks and raise awareness Rules-based solutions (planning)Insure risks

Q3 Introducing redundancy and fail-safe mechanismsResilience and the many R’s

Q4 Must stay out of it Not relying on statistics

Simple Create communication channelsStay connectedDon’t assume things are simple

Complicated Use external & internal opinions Use experiments to think out-of-the box

Complex Be patient and allow time for reflectionEncourage interaction

Chaotic Set up mechanisms to take advantage of opportunitiesEncourage debate Work to shift the content to complex

Page 15: Managing in an Age of Transitions - Scopes of Forecasting

Critically discuss Taleb’s

Methodology

Page 16: Managing in an Age of Transitions - Scopes of Forecasting

What impact the scopes of forecasting might have on

managers? Managers will need to develop interpersonal and multidisciplinary skills to better predict events and adapt to different situations

Leave place for randomness: learning to unlearn → great knowledge and preferences for data and information often lead to misinterpretation and engender adverse implications

Realise the cumulative effect of slow trends

Page 17: Managing in an Age of Transitions - Scopes of Forecasting

Summary The 4 Quadrants: a risk is either simple (well-defined and well-known) or complex (several variables to take into account). The risk is either normally distributed or fat-tailed (a small variable can have tremendous implications)

Black Swans are becoming more consequential and are unpredictable

People continue see patterns in misleading data Our minds focus on variability

Embrace randomness - The misuse of knowledge (information and data) and voluntary/involuntary ignorance about unpredictable events lead to false/unaccurate predictions

Methodologies categorizing risks give us advice to better address risk management but have to be critically discussed

Not reliable forecasting can influence firms success by missing growth opportunities.

Page 18: Managing in an Age of Transitions - Scopes of Forecasting

Concluding commentsForecasting is a tricky tasks and even more difficult over the long term. That is why companies have specialists (experts) that predict events regarding historical data and fact analysis. But they are considered to be wrong most of the time.

Our societies are mostly based on data, numbers, analysis and worship of knowledge. However, we realize that non-specialists can offer predictions as good as experts, which lead us to wonder whether one of our future challenges is going to be able to step back from knowledge and information, in order to improve the management of future societies.
