abductive reasoning from wiki

Deduction
allows deriving b as a consequence of a.
are the assumptions true? if so, the conclusions (validly arrived at) are true

Induction
Induction is inferring probable antecedents as a result of observing multiple consequents. Induction is modern algebra to deductive arithmetic.

Abduction
allows inferring a as an explanation of b or precondition a to be inferred from the consequence b. there are multiple possible explanations for b.

abduction can produce results that are incorrect within its formal system. Hence the conclusions of abduction can only be made valid by separately checking them
but when something is known about the likelihood of different causes for b, a, abduction

i.e. Aliens? Or just a bad souffle?
