Q. In the book you mention "the Wobegon effect." Want to tell us a bit about that?
A. In Garrison Keillor's fictional town Lake Wobegon, all the children are above average -- and when I ask a roomful of businesspeople to rate their own people skills, 90% say they're above average. We rate ourselves very high on thinking people like us, people trust us, we're great at getting along with other people, and so on. That's the Wobegon effect. What I'm saying is that really successful people are open to the idea that they may have strengths and weaknesses in their people skills, and the weaknesses may be holding them back.

Libertarian paternalism is the brainchild of Profs Thaler and Sunstein, but nudging is not. Nudging is good architecture, good design or good marketing and most nudges have been invented by private sector companies. Prof Thaler’s best policy idea – a pension plan called Save More Tomorrow – was tried by a manufacturing company rather than a government.

This study investigates whether the adverse effects of investors' behavioral biases extend beyond the domain of financial markets to the broad macro-economy. Our results demonstrate that risk sharing (RS) levels are higher in U.S. states in which investors have higher cognitive abilities and exhibit weaker behavioral biases"
"Because direct measures of cognitive abilities of stock market participants are not available, we use the demographic characteristics of the brokerage investors (e.g., income, education, age, social networks, etc.) to define a cognitive ability or “smartness” proxy for each investor and use these imputed cognitive ability measures to obtain aggregated state-level measures of cognitive abilities."
"The average RS in states with less sophisticated investors (= 0.131) is less than half of the average RS in states with greater investor sophistication (= 0.324). Collectively, our evidence indicates that the aggregate behavioral biases of individual investors infl‡uence the level of risk sharing across the U.S. states."
