An ironic term for all formulations, that are implicit reasoning. This is its usual expression:
" If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck. "

Did you hear sayng "If it looks like a duck, waddles and quacks, then it's probably a duck"? That's much talked-about duck test.
