INTRODUCTION

English translation pending.

CORE DEFINITION

The method supposes that a single historical turning point produced a different outcome, then reasons forward through the chain that would have followed, asking for example what Europe would look like if Napoleon had won at Waterloo. Its purpose is not fantasy but causal understanding: by comparing what did happen with what plausibly would have happened, the analyst isolates the contribution of one variable from the surrounding flow. History is thereby treated as contingent rather than destined, and the importance of a decision point becomes measurable.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Pick the pivot: choose the single variable whose contribution you want to measure. - Change only it: hold every other condition fixed while the pivot itself flips. - Compare worlds: read the variable's importance out of the gap between the two outcomes.

Anchor fast decisions

A single observed history contains no control group, so the causal weight of any one event cannot be read from it directly. Constructing the counterfactual supplies the missing comparison, and the difference between the two worlds estimates what the pivot contributed. The construction is only informative to the degree its downstream changes follow from the pivot rather than from the analyst's preferences.
