Bad Data Analysis and Psychology’s Replication Crisis

In 2014, a study published in JAMA Pediatrics linked playing aggressive video games to real-life aggression in a large sample of Singaporean youth. The study attracted considerable news media attention. For instance, a sympathetic article in Time magazine breathlessly reported its findings and suggested that brain imaging research found aggressive games change kids’ brains. But was the evidence from the Singapore study reliable? In recent years, concerns about the Singapore dataset have grown. UK scholars Andrew Przybylski and Netta Weinstein recently wrote that the way the dataset had been used by the primary authors was problematic. The analyses from the same dataset kept changing across published articles in suspicious ways. These shifting analyses can be a red flag for the data massaging that may produce statistically significant outcomes and hide outcomes that didn’t work out. Such practices may be unintentional or unconscious (scholars are only human after all). But they do suggest that the results could do with further scrutiny. When the dataset became available to my colleague John Wang and me, we re-analyzed the …

Sexualization in Gaming: Advocacy and Over-Correction

Even before its April 2019 release, the eleventh installment of the popular fighting game Mortal Kombat was generating waves for its presentation of female characters. But the grumblings are not what one might expect. After years of being criticized for sexualizing female characters, Mortal Kombat is now under fire from fans—including women—for not allowing the female characters to be sexy enough. Did Mortal Kombat’s developer overshoot the mark? Or are we beginning to see a reassessment of concerns that sexualized games are responsible for sexist attitudes toward women—an argument that increasingly became a mantra of progressive games criticism? Historically, games have catered to male audiences, even as increasing numbers of women and girls have joined the ranks of gamers. Given the rapidly changing gamer demographic, it was perhaps inevitable that games would eventually come in for criticism for under-representing playable female characters, and for presenting them as hyper-sexualized images when they were available. Much of this criticism was deserved, particularly the lack of alternative options featuring strong, less-sexualized playable characters. Indeed, I am on record …

Motivated Reasoning Is Disfiguring Social Science

On February 15, the American Psychological Association (APA) Council of Representatives voted for a resolution opposing parental spanking (full disclosure: I serve on the APA Council of Representatives but speak only for myself). The resolution statement presented spanking research as if data conclusively links spanking to negative outcomes in children such as aggression or reduced intellectual development. I happen to do some research on spanking’s effects on children. Although I am by no means a spanking advocate, I was alarmed by the way an inconsistent, correlational, and methodologically weak research field that routinely produces weak effect sizes was mischaracterized as consistent and strong. Unfortunately, this resolution is part of a larger bias among professional guilds such as the APA, wherein messy science is laundered for public consumption, presenting it as more impressive than it actually is. Many people in the general public believe that organizations such as the APA or American Academy of Pediatrics (AAP) are neutral, objective scientific organizations or that they are even part of the government. But they are largely professional guilds wherein members like me pay …
