Do geniuses sleep more?

There's no simple "yes" or "no" answer, as research suggests smarter people might sleep less or be night owls (especially children), but others need more rest due to their active brains, and historical figures show varied habits, from Einstein's 10 hours to Tesla's minimal sleep, often influenced by personality and societal pressure for productivity. While some studies link higher childhood IQ to later sleep times, many findings show intelligence isn't strongly tied to sleep duration, with some highly intelligent people needing less sleep and others needing more for recovery, debunking the "sleepless genius" myth.

What is the strongest predictor of IQ?

The best predictors of IQ involve a mix of genetics and early environment, with maternal IQ and parental socioeconomic status (SES) being consistently strong predictors, alongside physical markers like head circumference growth in early childhood and achieving developmental milestones early.
