00:00:00 — The Dunning-Kruger effect, with examples from investing and exercise
- ★★ Ali says the Dunning-Kruger effect might explain why smart people sometimes think they might be stupid. (hedged) — 00:00:00
- ★★ The psychologists David Dunning and Justin Kruger described the Dunning-Kruger effect, a cognitive bias, in 1999: people who are worse at something often overestimate how good they are, while those with high ability tend to underestimate it. — 00:00:00
- ★★ As an example of the Dunning-Kruger effect, Ali says that with easy-to-use investment apps many amateur investors might think they have cracked the code to making millions, while seasoned investors understand the unpredictability and complexity of long-term success. — 00:00:00
- ★★ As another example of the Dunning-Kruger effect, Ali says someone who has been working out for a few weeks might feel they know everything about exercise and nutrition, while dedicated athletes and trainers keep learning and adapting their routines. — 00:00:00
- ★★★ Under the Dunning-Kruger effect, Ali says, the highly skilled realise how much they do not know, because learning more uncovers a subject's complexity and makes them feel like a small fish in a big pond, while the less skilled are blissfully unaware of their ignorance and feel like a big fish in a tiny puddle. — 00:00:29
