When you say IQ is a curse it sounds fimiliar to me. It is thought that ego is the curse, not intelligence per se. Ego is when people are sort of fixated on their own self importance and the mind is dominating everything. Intelligence and your mind are supposed to be a tool to be used to achieve an end, but it itself is not be the end. Read the book "The Power of Now" it will show you.
There are things in the world that are important that the heart/emotions and body knows but the mind cannot explain, and too many people may be in their mind or ego. Scientific progress is something that is easily justified, easily explained away why we "should", and mabie there aren't really any "should's" in life, they could all be made up dillusions of the mind, which only sees why the person is right.
Well this isn't it entirely but its some food for thought.
