Abductive Fallacy

(a.k.a. Abduction)

Basing conclusions on guesses

Examples:

Astronomers don’t know for sure how the universe made its first stars, but they do have a reasonably good guess. ~ Talking Back, Water, water (almost) everywhere, Astronomy

Evolution uses Pierce’s abductive schema.

Abduction is guessing, and guessing isn’t a rational way to reason.
