Here’s where fallacies fail, you see.
Anecdotal fallacy - using a personal experience or an isolated example instead of sound reasoning or compelling evidence.
Appeal to probability – is a statement that takes something for granted because it would probably be the case (or might be the case).[2][3]
^the above are called structural fallacies, problems with the argument’s form.
But it doesn’t take into account the weight of the anecdote.
If the personal experience had a lot of weight, it might be relevant.
Probability is relevant. The argument for probability is not structurally unsound
Appeal to the stone (argumentum ad lapidem) – dismissing a claim as absurd without demonstrating proof for its absurdity.[13]
Argument from ignorance (appeal to ignorance, argumentum ad ignorantiam) – assuming that a claim is true because it has not been or cannot be proven false, or vice versa.[14]
Often times the argument is absurd. While it’s ignorant to say “preposterous” when someone presents a new idea, the idea that planes exist was absurd at the time. Absurd, but not impossible.
Science bases itself on argument from ignorance, after you repeat an experiment ten times you deem it to be true. Gravity has not been proven false. Therefore, gravity is a fallacy. Fallacy is a fallacy.
