g has pervasive, persistent effect on life chances
Why?g is ability to “catch on,” “figure things out”—required everywhere, always!
And—Premium on g keeps rising in modern
world, information age

Effect sizes vary systematically by life arena, task complexity
• Standardized academic achievement .8• Job performance—complex jobs*
• Years of education .6• Occupational level
• Job performance—middle-level jobs* .4-.5
• Income .3-.4
• Delinquency -.25
• Job performance—simple jobs* .2

IQ doesn’t predict happiness
True friendship
Minimizing conflict
Parental loveFamily commitment
Mutual joy
Non-material outcomes matter, too: E.g., social-emotional connectedness
![Page 20: Give Intelligence Its Due, But Put it In Its Place](https://reader035.vdocuments.us/reader035/viewer/2022062422/56814233550346895dae4dcf/html5/thumbnails/20.jpg)
• Shunning & social isolation = physical death when humans evolved
• Humans are acutely sensitive to social isolation• Being different, odd, “out-of-step,” unusual can isolate a
person• Extremely high (or low) IQ makes one unusual• Attributes that lead to creativity (marching to own
drummer) makes one unusual• So, high intelligence and creativity can pose psychic and
emotional challenges
• Those challenges are manageable if understood
