Why we use models

Mental models are frameworks that represent how something works in the real world. Strong learning develops accurate models by:

• Challenging existing misconceptions directly
• Creating predictions that can be tested against realit...

• We’re not as rational as we think. 
• We’re not prepared. We don’t understand the invariant ideas — the mental models — of how the world really works. 
• We don’t gather the information we need. We make decisions based on our “g...

Mental models are a set of ideas, which like an algorithm, shapes our perception and understanding of how the world operates.

And we need to evaluate the validity of these shortcuts and check the reliability of the mental models to ensure they are effective.
