So true.
I have known many people with high IQs. I even married one. Their IQ scores bought them spots in gifted classes and schools. Yet, overall, they were no more successful in their careers and their lives than other people. One was a member of Mensa, and in addition to her reported intelligence, she was very pretty. But, if she had never told me about her IQ, I would have never guessed. Her personal life was a mess, and her work performance was unimpressive. The only benefit her IQ bought her was some bragging rights.
Maybe an employer should consider an IQ score as one factor for certain types of work, but an employee's skills and work ethic are far more important in most jobs.
I know it is a TV show but, The Big Bang Theory is a classic example of this. Penny owns all the smart boys.
Her hidden lesson to us is that she tries and fails but still manages to bring it on.
