INTRODUCTION

English translation pending.

CORE DEFINITION

A staple of time travel fiction and a recurring structure in self-fulfilling prophecy, in which an agent acting to prevent an outcome sets in motion the chain that produces it. The causal sequence closes on itself, so no external origin of the event can be identified. The core claim is that preventive intent can be the causal mechanism of the outcome. The qualification is that the loop is a narrative and logical structure, and in ordinary life the cycle can be interrupted by changing the behavior rather than the goal.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Loop Detection: Check whether the action you take to prevent an outcome is itself producing that outcome. - Use Intent-Result Split: Compare your stated aim with the effect your behavior actually has. - Use External View: Ask how an outside observer would describe what your preventive effort is accomplishing.

Anchor fast decisions

Anxiety about an outcome changes behavior in ways that make the outcome more likely, and the resulting confirmation increases the anxiety, closing the loop. Because the intention is preventive, the person does not see their own action as the cause and therefore repeats it. The cycle persists until attention shifts from controlling the outcome to changing the behavior that is generating it.
