Only approximately 1% of the people in the world have an IQ of 135 or over - and most of these geniuses are men.
I don't know what the actual gender ratio is - it might be something like 12:1.
Males dominate both ends of the IQ distribution (the dumb end and the genius end).
Edit - good OP, Terry.
There's no point whinging about things 'not being fair'. That's what children do. In fact, it could be argued that the top 1% geniuses being successful is completely fair. IQ is a pretty good indicator of success.
