Why refer to langan's qualifications as "superbly qualified"

In the book "Outliers: The Story of Success" by Malcolm Gladwell, the author tells the story of Christopher Langan. Langan was about to participate in a game show called "1 vs. 100," which tested the contestant's knowledge of trivia against that of 100 random people in the "mob." The author argues that Langan was "superbly qualified" for this task because of his incredible intelligence.

Some of the reasons why Langan was considered brilliant are:

An IQ of one ninety-five. He was speaking by the age of six months. He got a perfect score on his SATs, even though he fell asleep during the test.
