Bad Reason Fallacy

The bad reasons fallacy stems from the claim that because the reason(s) given for a certain conclusion are bad therefore the conclusion must also be incorrect. This fallacy supposes that it is not possible to give a bad reason for a correct conclusion. In fact, it is possible to give bad reasoning for a valid conclusion.

Fallacy formula:

  • The reason A given for argument B is bad, therefore conclusion B is not valid

Example of Bad Reason Fallacy

Dogs are afraid of heights, therefore dogs don't fly.

It is true that dogs do not fly, but it not because they are afraid of heights.
