You Can be Too Smart for Your Own Good

You will agree with this, instantly. "Nothing could be more obvious!"  You will say.

But this is not obvious at all. Why should people be discriminated against, because they are smart? Because the people around them are not smart, and they do not want smart people around them, making them look stupid!

People want to feel good, and they are not much interested in, whether or not someone is right.

I am now studying programming, as a hobby. And in that limited world - you gotta be right! And determining if someone is right, is simplicity itself. You just send your code to a computer - and either it likes it, or it does not - and if does not like it, it will tell you, why it does not like it. "I was expecting this, but this is what you sent me. Fix it, and try again."

Can this be applied to the real world? Yes. You try to fix a problem, but likely as not - your fix will not work very well. But you have learned something, you know what doesn't work. And you try again, doing something slightly different, or entirely different.

This assumes you are in a country that allows you to experiment. Not many countries allow this.
