Ever been to a Mensa meeting? High IQ often correlates with eccentric habits. Those who think for themselves don't always make conformity to norms a high priority.
A study I read decades ago put work and social success with the 120-130 range.
‘work and social success with the 120-130 range.’
A high IQ can harm communication with lower IQs. Too large a lexicon AND alienation, such as stilted proper grammar.
I deliberately try to avoid words that are too fancy when a plain word works just as well.
“A study I read decades ago put work and social success with the 120-130 range.”
Exactly right. While some geniuses are successful in their field, the correlation with success lies in the median range. An IQ more than one standard deviation lower puts success out of reach—at least from a normal perspective—though many such people are successful to a degree and happy with their lives.
A deviation higher may grant some level of success, but often comes at the cost of alienation and isolation. To quote a wise man:
For in much wisdom is much grief, And he who increases knowledge increases sorrow.
