This is an optical illusion called Ebbinghaus illusion. It shows that when you put a circle around bigger circles, it looks smaller. But when you put it around smaller circles, it looks bigger despite that there’s no actual difference in size.
There’s this saying that you are the average of your friends. I think it’s the same thing, because we tend to be around people we don’t feel little in.
We are inclined to avoid uncomfortable situations.
If we want to grow, being the circle with bigger circles is a more optimal position to be in. There’s a lot of room for growth.
Unlike being the circle with smaller circles where we already feels big, there’s no incentive to grow.
