IQ is often dismissed as antiquated, misguided, or less important than personality traits. But according to Stuart Ritchie, an intelligence researcher at the University of Edinburgh, there’s a massive amount of data showing that it’s one of the best predictors of someone’s longevity, health, and prosperity. And psychologists have been able to replicate these findings over and over.

Here are nine facts that help explain IQ and why it matters.

1) Most people have average intelligence.

2) Having a higher IQ protects you from death. This is an uncomfortable one: According to the research, people with high IQs tend to be healthier and live longer than the rest of us.

3) IQ is correlated with career success and wealth, but not necessarily happiness. Like mortality, the association between IQ and career success is positive.

4) You’re probably stuck with what you got. Studies have found if you’re a smart kid, you’ll be a smart old person.

5) Intelligence peaks in your mid- to late 20s, and then slowly declines.

6) Around half the variance in IQ can be explained by genetics.

7) Genes are not the only thing that matters in intelligence.

8) Humans are getting smarter. Hurray! Mean IQ scores appear to be increasing between 2 and 3 points per decade.

9) IQ is increasing faster in developing countries.
