INVERT

A methodology of reasoning by inversion — defining the anti-objective (everything that would guarantee failure) and working backwards to eliminate the conditions for failure.

A methodology of reasoning by inversion. Instead of defining what one wants to achieve, it defines the anti-objective — everything that would guarantee failure — and works backwards to eliminate the conditions for failure.

Inspired by Charlie Munger's inversion principle: "Tell me where I'm going to die so I'll never go there."

Context & Strategy

How it was born

Formalised as a framework from a reasoning pattern that António Martins already used in consulting: before recommending any strategy, systematically list what would make it fail. INVERT transforms that pattern into a replicable process.

What it does in practice

Used as a pre-mortem tool before important strategic decisions. It is one of the support instruments for DECIDE-X and RIA (Reverse Intent Analysis). It also functions as a teaching tool in critical thinking programmes.
