Here is Barker:
Ironically, the bias toward seeing ourselves as better than average causes us to see ourselves as less biased than average too. As one research team concluded, “Most of us appear to believe that we are more athletic, intelligent, organized, ethical, logical, interesting, fair-minded, and healthy—not to mention more attractive—than the average person.
We’re more similar to others than we are different. Don’t fight this, embrace it. It is, apparently, the key to a much happier life.
It makes sense. If you had yourself convinced of your superiority, constantly facing reality would be a terrible source of stress. There’s always someone smarter, faster, stronger, richer, cooler.
Stay too humble, though, and you’d never achieve anything!
