LFotW: Argument from Personal Incredulity

I cannot explain, imagine, or understand this, therefore it cannot be true. However, reality is not limited by our ability to comprehend it, or by our comfort with it. Creationists are fond of arguing, for example, that evolution is false because they cannot imagine the complexity of life resulting from blind natural processes, but that does not mean life did not evolve.

Subtype: Appeal to Ridicule
This form of the argument from personal incredulity argues that a claim is false because it seems ridiculous. Of course, some claims are ridiculous and it is legitimate to arrive at such a conclusion after careful examination of the logic and evidence. However, it is a fallacy to dismiss a claim a-priori simply by labeling it ridiculous or absurd. Many ideas that initially seemed far-fetched, such as the notion that invisible tiny organisms cause disease, or that space and time are relative and not constant, turned out eventually to be proven scientifically valid.
