Backward Causation
Updated 2026-09-10
INTRODUCTION
English translation pending.
CORE DEFINITION
Backward causation, also called retrocausality, is the case where an effect precedes its cause in time. Causation in our world appears always to run forward, and this assumption is so deep that the reverse is hard to imagine. The entry examines whether that intuition can be shaken, and the paradoxes and free will problems that arise, including the bilking argument and the bootstrap paradox.
SCAFFOLDING EFFECT
Reduce cognitive load
- Test causal intuition: use cases where the effect precedes the cause to probe the direction assumption. - Apply bilking: ask whether the cause could be blocked after the effect has already been observed. - Clarify manipulation: examine what temporal structure the cause-as-handle picture silently presupposes.
Anchor fast decisions
The main obstacle to backward causation is not logical contradiction but conflict with the two cues by which we detect causal direction: temporal order, and whether manipulating the cause changes the effect. If the effect comes first, one could observe it and then block its cause, which is the bilking argument. Accommodating retrocausality requires showing why such bilking is impossible or harmless.
