Mental models are the internal representations your brain uses to simulate and predict how systems, situations, and people behave. Every judgment you make — from "will this merger succeed?" to "will this person react well?" — draws on your mental models.
The quality of your mental models determines the quality of your predictions. Accurate mental models produce accurate predictions; inaccurate models produce systematic errors that no amount of effort can overcome.
Metacognitive training is, fundamentally, mental model calibration. MindFrame helps you discover which of your mental models are accurate, which are subtly wrong, and which are badly miscalibrated — then provides structured practice to update them.
Charlie Munger's concept of a "latticework of mental models" captures the goal: building a diverse, well-calibrated set of models from multiple disciplines that can be applied flexibly to novel situations.
