The Bad Science Behind Jonathan Haidt's Call to Regulate Social Media

In his 1996 book, The Vision of the Anointed, economist Thomas Sowell sketched out a pattern that many of the "crusading movements" of the 20th century have followed. First, they identify a "great danger" to society, followed by an "urgent need" for government action "to avert impending catastrophe."

A new book by psychologist and author Jonathan Haidt, The Anxious Generation, argues that the government must regulate social media because it's causing a teen mental health crisis. Haidt is, in many ways, a model researcher because of his rigor, transparency, and openness to dissent. On this issue, however, he fits neatly into Sowell's framework.

Those best equipped to get attention from the government and the media are the most "articulate" people, Sowell observes, and they often reference opaque studies without explaining them. And Haidt is certainly articulate—his book is well-written and filled with compelling insights. But he claims far too much certainty for his views, based on research that is mostly junk. And he advocates for restrictive government policies without doing the simple tests that might support or disprove their value.

Academic studies often make use of statistical techniques that are hard for the average person to decipher, which is a shame because "most published research findings are false," as Stanford's John Ioannidis argued in a 2005 paper. Ioannidis wasn't just referencing the many scandals of fabricated data, conscious or unconscious bias, and misrepresented findings. Even top researchers at elite institutions have been guilty of statistical malpractice. Peer review is worse than useless, better at enforcing conventional wisdom and discouraging skepticism than weeding out substandard or fraudulent work. Academics face strong pressure to publish flawed research. Few have the skill and drive to produce high-quality publications at the rate required by university hiring and tenure review committees. Even the best researchers resort to doing some easy, low-quality studies. Bad studies tend
