Historicizing the liberal antiracism of Cultural Evolution.

The Cultural Evolution Society was established in 2015 to "catalyze a theoretical synthesis" in the scientific study of human culture. As a field of research, cultural evolution took shape in the 1970s and 1980s around the aim of incorporating culture into biology's modern evolutionary synthesis. Cultural evolution grew around the turn of the twenty-first century at the interface of population genetics and cognitive psychology. This article locates the origins of research on cultural evolution in projects of postwar scientific antiracism and U.S.-based debates about race and intelligence in the 1960s. Charting the development of prominent approaches to studying cultural evolution, I show how population geneticists and cognitive psychologists worked to redefine culture in statistical, populational, and geographic terms to politically neutralize the study of human difference. I situate the forms of genetic and cognitive culturalism that emerged as a result in a longer history of twentieth-century scientific antiracism.
