Thinking, Fast and Slow

Thinking, Fast and Slow is a 2011 popular science book by the Israeli-American psychologist Daniel Kahneman. Its main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive and emotional; "System 2" is slower, more deliberative, and more logical. The book delineates rational and non-rational motivations or triggers associated with each type of thinking process, and how they complement each other, starting with Kahneman's own research on loss aversion. https://en.wikipedia.org/wiki/Thinking,_Fast_and_Slow

• The book has been heavily criticized for relying on shoddy and non-reproducible studies. 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[49] of the studies cited in chapter 4, "The Associative Machine", found that their replicability index (R-index)[50] 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."[51] Others have noted the irony in the fact that Kahneman made a mistake in judgment similar to the ones he studied.[52] A later analysis[53] 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.
