Hold multiple maps simultaneously

For complex situations, develop two or three competing models and check which fits better.

Why it works

A single model creates single-frame vision: you find what you are looking for and miss what the frame excludes. Holding multiple models simultaneously forces the question of which one fits — which is a far more productive epistemic position than having one model and looking for confirmation. The discipline of building the alternative map also reveals what assumptions the original was hiding.

How to do it

1. For any significant situation, build at least two different explanatory models that each fit the current evidence.
2. Ask what each model predicts that the other does not — then look for evidence that distinguishes them.
3. Keep both alive until one is clearly ruled out by evidence, rather than defaulting to the one you built first.
4. Note when you are drawn to collapse back to one model out of discomfort with uncertainty.

Evidence

Multiple-hypothesis thinking is a recognized discipline in scientific reasoning and intelligence analysis. The "analysis of competing hypotheses" technique was developed explicitly to counter single-hypothesis anchoring in intelligence work. (clinical)

Holding multiple models is cognitively demanding and people often collapse to one under time pressure; it is best used for high-stakes decisions with adequate deliberation time.

Common mistake

Building an alternative model only to immediately discard it — the value comes from genuinely entertaining the alternative until evidence decides, not from performing the exercise.
