There is also a good podcast episode with an interview by Steven Levitt with the author ( https://podcasts.apple.com/au/podcast/75-self-help-for-data-... )
It might be of interest to HN types because it's essentially using loads of data to see what helps people.
The continued existence of homo sapiens over the last X years would be evidence undercutting SS-D's conjecture that intuitive decisions are wrong more often than right. Of course, to understand the relationship between claim and evidence it would be necessary to understand what SS-D means by "wrong."
As an example of right/wrong, he cites the relatively short lifespan of record stores compared to a dentist office as a method of deciding what kind of business to open. It isn't clear if SS-D is being facetious in terms of business opportunity options, but it is clear that SS-D deals in very low dimensional data, not information, knowledge or wisdom.
Skipping to the summary statistical result is a short-sighted decision method. To get Tower or Waterloo or any other cultural institution, many other ventures opened, innovated and failed as part of an evolution of innovation. To get evolution there must be mutation and selection. Survivorship bias makes the post-hoc claim that if only we did it the "right" way we need not have had all the short lived record stores. It doesn't admit that the "right" way wasn't known at the start.
