Appeal to probability

An appeal to probability (or appeal to possibility) is the logical fallacy of taking something for granted because it would probably be the case (or might possibly be the case).[1] Inductive arguments lack deductive validity and must therefore be asserted or denied in the premises.

Example

A fallacious appeal to possibility:

Something can go wrong (premise).
Therefore, something will go wrong (invalid conclusion).
If I do not bring my umbrella (premise)
It will rain. (invalid conclusion).

Murphy's law is a (typically deliberate, tongue-in-cheek) invocation of the fallacy.

gollark: Also codersnet. But SC exists.
gollark: I have literally never encountered that.
gollark: You probably can't parse (X)HTML with any sane and reasonably sized Lua patterns.
gollark: <@356209633313947648> There's a spec for procedural HTML5 parsing somewhere.
gollark: You can send two messages very fastr in sequence, and in two "parallel" coroutines, but not literally the same time.
