In the law, this pertains to a doctrine known as Standard of Review. Just to cut through the legalese, a standard of review is a statement by the law of which person bears the burden of proof, and how much proof, or what degree their evidence must raise, before they are deemed to have met that burden.
And I mention that doctrine because, as Ta-Nehisi Coates once pointed out, the most common form of bigotry isn’t overt or simplistic hatred. It’s varying the standard of review to whatever standard is required for me to disconfirm the uncomfortable truth you just uttered.
