Malcolm Gladwell is a different type of psychology book than I usually read. He has a place introducing ideas in broad strokes, but it’s a lower tier of informative than books written by psychologists who have broad understanding of the research and have done some original study of their own. If you want an extremely accessible introduction to the idea of expertise and the value of practice, this is OK.


If you want a well sourced, more comprehensive understanding of what the research does and doesn’t say, and how to apply the principles supported by the research, read Peak by K Anders Ericsson and Robert Poole. It’s denser, but it discusses some of the flaws of Gladwell’s presentation and is overall held to a more rigorous standard.
