“On the other hand, Marilyn Savant has an IQ of 190, and is nothing more than a columnist for the Sunday inserts.”
Approximately 6,000,000 Americans would qualify to join Mensa, should they apply.
Over 100,000 of them would further qualify to be an ‘MM’, one who is to Mensans in the aggregate as Mensans are to the general population.
More than 2,000 of these folks are smarter than Marilyn; there are a lot of smart people in this world, but that hasn’t solved our problems.
That top 2% is what Mensa is aiming for. Because they take anyone who has ever scored in the top 2% of a qualifying test, their net is actually quite a bit broader than that, considering outlier scores from the much larger population.
