CORE DEFINITION

If you go back in time and kill your grandfather, you would not be born, and thus could not go back to kill him. The causal chain destroys itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Logical consistency check. When designing complex business models or scripts, check for such a 'self-devouring premise' dead loop. If your growth strategy relies on 'low prices', and 'low prices' lead to a decline in service quality, thereby stifling growth, that is a grandfather paradox.

Anchor fast decisions

If you go back in time and kill your own grandfather, you would not be born, and thus could not go back to kill him, forming a logical contradiction. Used to question the causal consistency of backward time travel.
