Explanation

The Appeal to Consequences fallacy occurs when an argument suggests that a premise cannot be accurate because the consequences of the premise's truth would be unpleasant or otherwise undesired (i.e. an Appeal to Force), or that a premise is likely to be accurate because the conclusion would be good or desirable (i.e. Wishful Thinking).

Example

  1. If evolution is true, then humans are just intelligent, bipedal apes.
  2. I don't want to be an ape.
  3. Therefore, evolution is untrue.

This is fallacious because the listener is so unhappy with the prospect of being an ape, that they refuse to accept evolution as true based on their feelings about the consequences of that truth. In reality, of course, premises are accurate even if we want them to be inaccurate, and premises are inaccurate even if we want them to be accurate.

Avoiding This Fallacy

Truth matters in logical debates; our emotions or feelings about the truth do not. While human emotions, feelings, and values will always influence what we decide to do based on our knowledge of the situation, that knowledge cannot be unduly influenced by our emotions or values if it is to be true knowledge.
