logical fallacies fallacy

Personal Incredulity

Because you found something difficult to understand, or are unaware of how it works, you made out like it's probably not true.

Complex subjects like biological evolution through natural selection require some amount of understanding before one is able to make an informed judgement about the subject at hand; this fallacy is usually used in place of that understanding.

Example: Kennedy drew a picture of a fish and a human and with effusive disdain asked Dick if he really thought we were stupid enough to believe that a fish somehow turned into a human through just, like, random things happening over time.
