Abductive reasoning

Abductive reasoning

en.wikipedia.org/wiki/Abductive_reasoning

Deduction and induction are boring, like a clean math problem or the statistical normal distribution. Abductive reasoning is what you do in the real world.

  • Deductive reasoning allows deriving b from a, only where b is a formal logical consequence of a.
  • Inductive reasoning allows inferring b from a, where b does not follow necessarily from a. a might give us very good reason to accept b, but it does not ensure b.
  • Abductive reasoning allows inferring a as the cause of b. As a result of this inference, abduction allows the precondition a to be abducted from the consequence b.

Abduction is formally equivalent to the fallacy of affirming the consequent (post hoc ergo propter hoc) because of multiple possible explanations for b.
