If scientists retract research that challenges reigning orthodoxies, politics will drive scholarship.
The Proceedings of the National Academy of Sciences is a peer-reviewed journal that claims to publish “only the highest quality scientific research.” Now, the authors of a 2019 PNAS article are disowning their research simply because I cited it.
Psychologists Joseph Cesario of Michigan State and David Johnson of the University of Maryland analyzed 917 fatal police shootings of civilians from 2015 to test whether the race of the officer or the civilian predicted fatal police shootings. Neither did. Once “race specific rates of violent crime” are taken into account, the authors found, there are no disparities among those fatally shot by the police. These findings accord with decades of research showing that civilian behavior is the greatest influence on police behavior.
In September 2019, I cited the article’s finding in congressional testimony. I also referred to it in a City Journal article, in which I noted that two Princeton political scientists, Dean Knox and Jonathan Mummolo, had challenged the study design. Messrs. Cesario and Johnson stood by their findings. Even under the study design proposed by Messrs. Knox and Mummolo, they wrote, there is again “no significant evidence of anti-black disparity in the likelihood of being fatally shot by the police.”
