Academics are now refusing to make accurate information public lest any conclusions run counter to the leftist narrative.
In 2019, the Proceedings of the National Academy of Sciences (“PNAS”), a peer-reviewed journal, published a study from two psychologists showing that American police were not shooting blacks as disparate rates compared to other races. In the most recent issue of PNAS, the psychologists withdrew the study, not because it was wrong, but because they objected that conservatives were using the study to challenge the Black Lives Matter narrative.
The psychologists, Joseph Cesario of Michigan State and David Johnson of the University of Maryland, studied 917 instances, from 2015 through 2019, in which police fatally shot civilians. They were trying to determine whether race could be a factor in predicting shootings. They found that it could not.
Heather MacDonald cited the article when she appeared before Congress in September 2019 and wrote about it in a City Journal article. Regarding that article, it’s essential to know that MacDonald noted that two Princeton political scientists challenged the study, but that both Cesario and Johnson stood by their original findings.
The fact that MacDonald used peer-reviewed data to show that American police are not systematically massacring blacks upset academia so much that Michigan State demoted physicist Steve Hsu, who had approved funding for the research. (Michigan State, by the way, is home to Christina Wyman, the associate professor who wrote an opinion piece about racism that is so stupid, to paraphrase Billy Madison, we are now dumber for having read it.)
