 who stay up late have higher IQs, at least according to one study. Also, they're better at drawing larger conclusions from less evidence, and they have better problem solving skills. So can we finally knock your mom off her wake-up early high horse? Well, not quite, because early risers have their own strengths too. They perform better at work, get better grades, and they might even have better verbal skills. So though we technically can't say one is better, we will just point out that Lady Gaga, Elon Musk, Barack Obama, Taylor Swift, and Winston Churchill are all known night owls. So take that mom.
