's review

it was amazing

I did not just read it. I studied it.
Carl Icahn boasts that "While others try to make money doing artificial intelligence, I do it by studying natural stupidity."
If there was a book about natural stupidity, then this is it.

There is a flaw in the chapter on regression to the mean.

A: "Highly intelligent women tend to marry men who are less intelligent than they are. "
B: "The correlation between the intelligence scores of spouses is less than perfect."

He claims that A and B are "algebraically equivalent".

A and B are not equivalent, and A cannot be inferred from B. For example when the correlation is perfect in the high intelligence region, but bad in the low intelligence pairings. (This is even plausible, since more intelligent people would pair themselves more efficiently than the less intelligent ones.) In this case B would still hold, but A would not anymore.
