Episode notes
Childhood Curiosity
- David Robson's interest in intelligence began in childhood due to the 11+ exam, an IQ test determining school placement.
- He later observed that high-achieving scientists sometimes displayed irrationality in other areas of their lives.
What IQ Tests Measure
- IQ tests measure general intelligence, correlating with academic and professional success, especially in intellectually demanding fields.
- However, IQ isn't the sole determinant of success; other mental traits are crucial.
IQ and Cognitive Biases
- High IQ doesn't always mean higher rationality; some biases are unaffected by IQ, while others, like motivated reasoning, can be worsened.
- Intelligence can protect irrational beliefs, as seen with Arthur Conan Doyle's paranormal beliefs despite contradictory evidence.
