What causes very highly educated(Masters and Doctorate Degrees)& extremely intelligent(IQ over 140)?

IQ is not the only measure in terms of success. Because success depends on a lot of factors and IQ solely cannot be the ideal replacement for that. People having good degrees are very intellectual but due to the lack of charisma and quality of being socially noticeable, they often fail to make their mark.

But the ones who have relatively an average IQ and moderate education, they always try to focus on their extra qualities. As a result, they get an edge in the path of being successful.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
