Equal Representation is Inequality, and Other Fallacies: A Commentary on Roberts et al. (2020)
In an article in Perspectives on Psychological Science, Roberts et al. (2020) claimed there is significant racial inequality in the publication process within psychology. Roberts et al. raise important questions, but some of their conclusions are inadequately supported. Among other things, they claim to have demonstrated that there is racial inequality in psychological research but do not define a threshold to separate inequality from equality. In addition, Roberts et al. fail to account for population base rates in U.S. demographics when drawing inferences. Specifically, they interpret their bibliometric analysis as indicating an over-representation of White authors in social and developmental psychology with no consideration of base rates. I demonstrate that when base rates are considered, the data actually show equal representation in the 1980s, 1990s, and 2000s, and White under-representation in the 2010s in both subfields. They also report a correlation between non-White editorship, non-White authorship, and non-White participant recruitment, and then suggest that editorship causes an increase in authorship and participant recruitment. They do not consider that demographic change—an overall increase in the proportion of non-Whites in the U.S.—is a better explanation than psychological bias for this association. They claim that race is an unpopular topic but a comparative PsycInfo analysis shows race may be one of the most popular topics in psychology. Their method for assessing a focus on race is also downward biased.
