The argument from incredulity, also  known as appeal to common sense,  

is a logical fallacy where one asserts  that a proposition must be false because  

it contradicts one's personal beliefs or  intuition, or seems difficult to understand.

Instead of presenting evidence,  the person relies on a lack of  

imagination or personal incredulity as  'proof' that the argument is invalid.

Everyday Example: A person is presented with  the concept of quantum entanglement, where  

two particles can instantaneously affect each  other's state, no matter how far apart they are.

They respond, "That's impossible; I can't see  how it would work. Therefore, it cannot be true."

This person is dismissing well-documented  scientific evidence based on their own inability  

to comprehend the concept, rather than on any  logical refutation or contradictory evidence.
