Freakonomics asks, “Why is there so much fraud in academia,” but without addressing one big incentive for fraud, which is that, if you make grabby enough claims, you can get featured in . . . Freakonomics!

There was this Freakonomics podcast, “Why Is There So Much Fraud in Academia?” Several people emailed me about it, pointing out the irony that the Freakonomics franchise, which has promoted academic work of such varying quality (some excellent, some dubious, some that’s out-and-out horrible), had a feature on this topic without mentioning all the times that they’ve themselves fallen for bad science.

As Sean Manning puts it, “That sounds like an episode of the Suburban Housecat Podcast called ‘Why are bird populations declining?'”

And Nick Brown writes:

Consider the first study on the first page of the first chapter of the first Freakonomics book (Gneezy & Rustichini, 2000, “A Fine is a Price”, 10.1086/468061), in which, when daycare centres in Israel started “fining” parents for arriving late to pick up their children, the amount of lateness actually went up. I have difficulty in believing that this study took place exactly as described; for example, the number of children in each centre appears to remain exactly the same throughout the 20 weeks of the study, with no mention of any new arrivals, dropouts, or days off due to illness or any other reason. Since noticing this, I have discovered that an Israeli economist named Ariel Rubinstein had similar concerns (https://arielrubinstein.tau.ac.il/papers/76.pdf. pp. 249–251). He contacted the authors, who promised to put him in touch with the staff of the daycare centres, but then sadly lost the list of their names. The paper has over 3,200 citations on Google Scholar.

I replied: Indeed, the Freakonomics team has never backed down on many ridiculous causes they have promoted, including the innumerate claim that beautiful parents are 36% more likely to have girls and some climate change denial. But I’m not criticizing the researchers who participated in this latest Freakonomics show; we have to work with the news media we have, flawed as they are.

And, as I’ve said many times before, Freakonomics has so much good stuff. That’s why I’m disappointed, first when they lower their standards and second when they don’t acknowledge or wrestle with their past mistakes. It’s not too late! They could still do a few shows—or even write a book!—on various erroneous claims they’ve promoted over the years. It would be interesting, it would fit their brand, it could be educational and also lots of fun.

This is similar to something that occurs in the behavioral economics literature: there’s so much research on how people make mistakes, how we’re wired to get the wrong answer, etc., but then not so much about the systematic errors made in the behavioral economics literature itself. As they’d say in Freakonomics, behavior can be driven by incentives.
