How Do You Pick Which Mental Models to Learn?

When deciding which mental models to learn, consider the relevant actors involved and whether it's a single decision-maker or a strategic situation. Evaluate if the decision-maker is rational or relying on rule-of-thumb heuristics. Assess the social, cultural, and economic context in which the decision is being made. Consider the frequency of the decision and the stakes involved in determining the level of rationality. Lastly, determine if the decision is made by an individual or an organization to understand the decision-making process.
