I'm confused. Is the 100 IQ value's meaning, "average intelligence" (it's also supposed to be the median value, half of the population has an IQ around 100) stuck to a single point in the past for a certain cohort? How can IQ scores decline?
- Camillo 8y agoScores are periodically renormalized to a new sample to keep 100 the median, but you can normalize to a single baseline to compare across time.
