Nobel-laureate (2002, economics) Daniel Kahneman (Princeton) published his popular book “Thinking Fast and Slow” in 2011 to much acclaim. His book became an instant best-seller and won many awards and prizes; see here, for example. Kahneman’s field is psychology, however, and if you know anything about the “replication crisis” in this field, you may already know where this blog post is headed. Specifically, how much of the social psychology research cited in Kahneman’s 2011 book is either bogus or suspect? This is precisely the question that Ulrich Schimmack (University of Toronto) decided to answer, and the results–available here on his influential R-Index blog–aren’t pretty! Professor Schimmack’s devastating analysis of the work cited in Kahneman’s 2011 book makes me wonder what empirical studies in other fields would fail to replicate if subjected to such scientific testing? The moral of this story? You may have heard the phrase “trust the science,” but the field of social psychology should serve as a warning to us all.
