Evidence‑Based Bias

A bias where the slogan “evidence‑based” is used to shut down debate rather than to guide it. The user claims their position is evidence‑based and the opponent's is not, without actually comparing evidence quality. Evidence‑based bias often involves cherry‑picking studies that support one's view, ignoring contradictory evidence, and treating the phrase as a magic incantation that ends discussion. It is common in policy debates where all sides claim to be evidence‑based, but only one is allowed the label. The bias is a form of epistemic credentialing, not genuine inquiry.

Example: “He said his policy was ‘evidence‑based’ and hers was ‘ideological,’ then refused to discuss the actual studies—evidence‑based bias, using the label as a cudgel.”
