Part of the book has been swept up in the replication crisis facing psychology and the social sciences. It was discovered many prominent research findings were difficult or impossible for others to replicate, and thus the original findings were called into question. An analysis[51] of the studies cited in chapter 4, "The Associative Machine", found that their replicability index (R-index)[52] is 14, indicating essentially low to no reliability. Kahneman himself responded to the study in blog comments and acknowledged the chapter's shortcomings: "I placed too much faith in underpowered studies."[53] Others have noted the irony in the fact that Kahneman made a mistake in judgment similar to the ones he studied.[54]

A later analysis[55] made a bolder claim that, despite Kahneman's previous contributions to the field of decision making, most of the book's ideas are based on 'scientific literature with shaky foundations'. A general lack of replication in the empirical studies cited in the book was given as a justification.
