Sociology paper critiques systemic racism as default disparity cause

A recent position paper by sociology professor Ilana Redstone argues that the field of sociology frequently treats systemic racism as an unquestioned default explanation for racial disparities. Instead of viewing it as a hypothesis requiring rigorous investigation and evidence, assumptions surrounding the origins of these disparities have allegedly undermined academic inquiry. The author notes that challenging this prevailing conceptual framework has become professionally costly and difficult within the discipline. This dynamic threatens objective scientific analysis and restricts open debate on complex social issues.
