GOOD NEWS FOR PEOPLE STILL AWAKE. SCIENCE PUT YOUR BEDTIME ON AN IQ SCOREBOARD 🚨🦉🧠😂
Parents said: sleep early, wake early, win at life.
Then a 2009 London School of Economics paper looked at thousands of young adults and found the late group scored higher. 🧾
What is IQ?
IQ (intelligence quotient) is a test score for how well a person can reason, solve problems, and learn. Higher IQ = stronger score on those skills. Not “good person.” Only a number from a test. 📊
Average work-night bedtimes 🌙
🔶 Lower IQ (under 75): about 11:41 PM
🔷 Middle IQ (90–110): about 12:10 AM
🔸 Top IQ (over 125): about 12:29 AM
For almost all of human life, night was not extra work time. It was dark. Hard to see. Hard to walk. Full of animals that hunt at night.
Old rule ✅
✅ wake with the sun
✅ work in daylight
✅ sleep when it gets dark
Bright lights, cities, phones, and 24/7 life are new. Staying up late to think, build, game, or solve hard problems is a new habit for humans. 🌍💡
Why higher IQ shows up more at night (paper’s idea):
smarter people break old habits a bit more.
Old clock: dark = sleep.
Modern life: one more idea, one more task.
High-IQ group says yes a little more often. 🧠✨
Do not get too proud at 1 AM ⚠️
✅ Pattern is real in that big US sample
⚠️ The gap is small
🟥 Sleeping at 5 AM does not make a genius
🟨 Short sleep still hurts memory and thinking
A 2024 Imperial College London study (about 26,000 people) also found night people often score higher on brain tests. But 7–9 hours still wins for a sharp brain.
If human past ran on sunrise and fire light, why do higher test scores now lean toward people who stay up after dark? 👇
