An ordinary club player will manage about half. Now scramble the same pieces into a random arrangement and show it again, and most of that advantage disappears. It is the most replicated finding in the psychology of expertise, and the conclusion drawn from it is substantially correct: expertise is not a bigger memory but a better organized one. Almost every specific claim usually attached to it, however, is wrong in some interesting way.\nIn this episode we look at how years of experience reorganize perception itself. We follow Adriaan de Groot from the 1938 AVRO tournament to the recall study of 1944 that had four participants, one of whom was de Groot. We watch William Chase and Herbert Simon turn a vague idea into something you can count, and then watch Simon go back 23 years later to correct his own most cited claim. Along the way we find out where the famous figure of 50,000 chunks actually came from, what an expert's eyes are doing that yours are not, and why the same perceptual machinery that makes a master brilliant can briefly make them perform like a player 600 rating points weaker.\n\nKey Topics Covered\n\nDe Groot's two experiments: thinking aloud at AVRO 1938, and the separate recall study of 1944\nGrandmasters do not search deeper (6.8 versus 6.6 half moves) and they decide faster\nWhere the famous 93 / 72 / 51 recall figures come from, and the four people behind them\nWhy de Groot never tested a novice, and how his own word...","thumbnail_url":"https://img.transistorcdn.com/FqjMDaQUSm1bYfkwwD6aDUnSGdwLjCiheWhxBb00zow/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS84YjIz/YzkwMzlmNGM5YmEw/NTJkOGYyMTk0YTMw/ZWM0Zi5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
