   To be an  anti-expert  about a topic is to be reliably wrong about that topic. Egan and Elga (2005) distinguish being unreliable, as when a compass does not point north when facing north, from being anti-reliable, as when a compass points south when facing north. They also give the example of directions while driving: When someone is an anti-expert about directions, whenever they think they should go left they should really go right and whenever they think they should go right, they should really go left.
