The better quality our mental model is, the better our product or output will be
Summary
- The better quality, and more detailed our mental model is, the better our product or output will be.
Details
- This applies to everything:
- chess. our mental model of the board and pieces and how they move will dictate which moves we make.
- music
- art: experts have a huge mental model of art from everywhwere that they are able to compare to their own art
- Developing a mental model requires analysis, prediction, revision of our model depending on teh result.
- A detailed mental model allows us to make faster and better quality predictions and decisions
Reflections
- This is such a significant idea. it also explains why repeating somethign many times but not learning is not actually changing your mental model

serious about developing skills on the chessboard will do it mainly by spending countless hours studying games played by the masters. You analyze a position in depth, predicting the next move, and if you get it wrong, you go back and figure out what you missed. Research has shown that the amount of time spent in this sort of analysis—not the amount of time spent playing chess with others—is the single most important predictor of a chess player’s ability. It generally takes about ten years of this sort of practice to reach the level of grandmaster.
Mental representations aren’t just for chess masters; we all use them constantly. A mental representation is a mental structure that corresponds to an object, an idea, a collection of information, or anything else, concrete or abstract, that the brain is thinking about. A simple example is a visual image. Mention the Mona Lisa, for instance, and many people will immediately “see” an image of the painting in their minds; that image is their mental representation of the Mona Lisa. Some people’s representations are more detailed and accurate than others, and they can report, for example, details about the background, about where Mona Lisa is sitting, and about her hairstyle and her eyebrows.
So everyone has and uses mental representations. What sets expert performers apart from everyone else is the quality and quantity of their mental representations. Through years of practice, they develop highly complex and sophisticated representations of the various situations they are likely to encounter in their fields—such as the vast number of arrangements of chess pieces that can appear during games. These representations allow them to make faster, more accurate decisions and respond more quickly and effectively in a given situation. This, more than anything else, explains the difference in performance between novices and experts.
What exactly is being changed in the brain with deliberate practice? The main thing that sets experts apart from the rest of us is that their years of practice have changed the neural circuitry in their brains to produce highly specialized mental representations, which in turn make possible the incredible memory, pattern recognition, problem solving, and other sorts of advanced abilities needed to excel in their particular specialties.
This is an example of one way in which expert performers use mental representations to improve their performance: they monitor and evaluate their performance, and, when necessary, they modify their mental representations in order to make them more effective. The more effective the mental representation is, the better the performance will be.
