I read this book after completing my exposition of overcompensation, how a stressor or a random event causes an increase in strength, in excess of what is needed, like a redundancy. I was also looking for evidence of convex reaction to stressor, or the effect of a mathematical property called Jensen's inequality in domains and found it exposed here (in other words, why a combination low dose (most of the time) and high dose (rarely) beats medium dose all the time. The authors presents the evidence for the phenomenon in the following: 1) acute stressors cum recovery beat both absence of stressors and chronic ones (this includes thermal variations); 2) stressors make one stronger (post traumatic growth); 3) risk management is mediated by the deep structures in us, not rational decision-making; 4) winning causes an increase in strength (the latter are more complicated effects of convexity/Jensen's Inequality).
Great book. I ignored the connection to financial markets while reading it. But I learned that when under stress, one should seek the familiar.
Bravo!
