The Very Definition of "Capper"

Huh.

Ritholtz defines "Cognitive Dissidents":

They are Cognitive Dissidents. They will continue to dissent from reality for as long as it takes to get everyone else to believe as they do, no matter how much evidence there is to the contrary.

If you engage with a Cognitive Dissident, it is futile to try to use facts or data, for theirs is a belief based upon Faith. You cannot convince a person of a fact if it conflicts with their deeply held, nearly religious convictions.

Thus, when confronted with someone who has a fervent belief based not on evidence or reason or data or logic, do not waste your time convincing them the earth is not flat; their cognitive facilities simply will not allow them to recognize the world is round.

Couldn't have said it better.
