> It’s worth noting that many of the results in Thinking, Fast and Slow didn’t hold up to replication. Irony is, Kahneman had himself written a paper warning about generalizing from studies with small sample sizes: "Suppose you have run an experiment on 20 subjects, and have obtained a significant re- sult which confirms your theory (z = 2.23, p < .05, two-tailed). You now have cause to run an additional group of 10 subjects. What do you think the probability is that the results will be significant, by a one-tailed test, separately for this group?" "Apparently, most psychologists have an exaggerated belief in the likelihood of successfully replicating an obtained finding. The sources of such beliefs, and their consequences for the conduct of scientific inquiry, are what this paper is about." Then 40 years later, he fell into the same trap. He became one of the "most psychologists". http://stats.org.uk/statistical-inference/TverskyKahneman1971.pdf http://stats.org.uk/statistical-inference/TverskyKahneman197...
