Mental Models

Simplified frameworks and representations of how the world works, used to make sense of complex situations, anticipate consequences, and make better decisions with incomplete information.

A founder with a rich library of mental models thinks faster and makes fewer systematic errors than one reasoning from scratch each time. Models like compounding, second-order effects, and inversion provide shortcuts to clearer thinking.

A founder applies the inversion mental model to her marketing problem. Instead of asking "how do I get more customers?" she asks "what would guarantee I lose all my customers?" The exercise surfaces four critical mistakes she is currently making, each of which she immediately corrects.
