The most useful mental models

Philosophy and science know many mental models that improve our lives. In this article, I extract most useful and valuable.

1. The Pareto Principle, which states that roughly 80% of the effects come from 20% of the causes. This model can help individuals prioritize their efforts and focus on the most important tasks.

2. The 80/20 rule, which is a specific application of the Pareto Principle and suggests that in many cases, 80% of the outcomes come from 20% of the inputs.

3. The Eisenhower matrix, which is a tool for prioritizing tasks based on their urgency and importance.

4. The SWOT analysis, which is a method for identifying and analyzing an organization’s strengths, weaknesses, opportunities, and threats.

5. The five forces model, which is a tool for analyzing the competitive forces in an industry and predicting the likely profitability of that industry.

6. The cognitive bias codex, which is a comprehensive list of common cognitive biases and ways to guard against them.

7. The Dunning-Kruger effect, which is the tendency for individuals with limited knowledge or skill in a particular area to overestimate their abilities.

8. The double-entry bookkeeping system, which is a method for recording and analyzing financial transactions.

9. The scientific method, which is a systematic approach to conducting experiments and making observations to test hypotheses and theories.

10. The six thinking hats, which is a technique for approaching problem-solving from multiple perspectives.
