IQ correlates to overall success - unless a high IQ individual is surrounded by short sighted,
fiat/power motivated, morons in leadership.
Overall success (long game) is still likely, however having to constantly dumb down intelligence to adapt to power constructs throttles and delays innovation and is like playing a game of telephone with 3 year olds.
Seems like those with high intelligence level are not just concerned not just with their own overall success, but the success of humanity in its many expressions of culture and sovereignty.
