A critical overview of the credibility of accepted empirical evidence in sociology, and requirements for more credible evidence. Topics include a series of research case histories, including race and gender inequality, the gender pay gap, the consequences of both marriage and divorce, the prevalence and patterns of emotional well-being, the specification of intersectionality in research, misinterpretation of older evidence, the resolution of conflicting evidence, and the historical decline in the role of evidence in shaping beliefs.
