According to the folk conception of having evidence, if the butler killed the victim right in front of me, I have evidence that the butler killed the victim. According to the vast majority of experts in the nature of evidence, that’s only the case if I have the corresponding seemings and beliefs. Experts think the having relation is in the head. Laymen disagree. This paper argues that experts are wrong, and, furthermore, that the expert conception of the having relation is highly problematic functionally—in that it preempts evidence had from playing its roles in accountability, moral and legal. Experts should engineer their conception to fit the laymen’s.
