Why Is Terence So Smart?

He may well be the smartest person in the world.

With an IQ of 230, Terence Tao was taking college maths courses at 9 and received a PhD from Princeton at the age of 20.

Results, from IQ testing the world's population:

• One percent had an IQ above 135

• Five percent had an IQ between 125 and 135

• Sixty-six percent had an IQ between 85 and 115

• Five percent had an IQ between 65 and 75

• One percent had an IQ under 65

• Twenty-two percent either never showed up or were the folk with IQs between 115 and 125; and between 85 and 75.

Questions

Someone asked the question:
"Oh yes ... so like 4.875 billion people did this test?"


My reply:
A sample would have been taken of the human population. For example, let's say invitations were sent out to a sample size of 100,000 people to appear for IQ testing; and as a result, only 78,000 bothered to show. Thus I wrote: "Twenty-two percent either never showed up or were the folk with IQs between 115 and 125; and between 85 and 75."

If anyone else has a question, please feel free to ask.
