The effect of your childhood best friend on your IQ

You may have heard the Jim Rohn quote, “we are the average of the five people we spend the most time with”, but you may not realise how early that becomes true. In the book Atomic Habits, author James Clear discusses the norms of cultures, and how the people around us shape who we become:

“…one study found that the higher your best friend’s IQ at age eleven or twelve, the higher your IQ would be at age fifteen, even after controlling for natural levels of intelligence. We soak up the qualities and practices of those around us.”

Who would have thought that your 12-year-old best friend’s IQ would affect your own IQ at age 15? It’s both terrifying and enlightening at the same time!
