This report chronicles and quantifies the persistent commitment to "diversity, equity, and inclusion" (DEI) in higher education hiring practices. Ideological Insistence quantifies the prevalence of DEI statements by surveying open positions, from the janitors to the deans, on the job boards of 89 public universities across 11 states, as well as on the job boards of the eight Ivy League universities and the Massachusetts Institute of Technology. For this study we have assembled a dataset of more than 23,000 advertised job listings. Our dataset, to our knowledge, is the single largest study of diversity statements—of ideological insistence—at American universities.
