MERCER COUNTY, Mo. -- Where would you expect to meet a guy with an IQ so high that tests can't even measure it?

Christopher Langan lives on a northern Missouri farm surrounded by fields and animals. For decades he has worked on a theory. But if you see what he writes, how much of his cognitive theoretic model of the universe would you understand?

"My theory is mapping a correspondence between language of thought and the real world," Langan told KMBC's Maria Antonia.

In 1999, ABC aired a story on Langan. They sent him to a neuropsychologist for a standard IQ test -- two hours of problem solving. It was reported that his score was too high to measure.

Experts said most people have IQs around 100. College graduates average 120. Above 130 qualifies for membership in Mensa. Langan's estimated IQ has been reported at 195. Only one in 100 million people have a score at that level, Antonia reported.

"I like to maintain a little bit of modesty because it's healthy to do that. It's not healthy to get a big head," Langan said.

But from the time he was a boy, Langan he knew he was special.

"They skipped me a few grades," Langan said. "I started suspecting that I was different then."

Despite the smiles in old photographs, Langan told Antonia that growing up smart and poor got him beat up in school and at home.

"In my family it was not politically correct to be a genius. My stepfather used to tell me nobody likes a smartass," Langan said.

Antonia reported that Langan started bodybuilding to fight back.

Now Langan's name and his work appear in books. Langan said he never finished college, citing a lack of money, transportation and patience.

"So at that point, I dropped out and became a blue-collar guy," Langan said.

In places like West Hamptom Beach, New York, Langan worked as a bar bouncer.

He said he has been asked, "If you're so smart, why aren't you filthy rich?"

Langan said he has always chartered a different course.

"Having a lot of nice stuff is not something anybody has any business associating with a genius," Langan said.

Antonia reported that Langan has a lot of books, and one purpose, which is his theory.

"I can remember asking my grandfather, 'Is there a God?'" Langan told Antonia.

Now in his 50s, that is what Langan's been working to prove all along.

"So, if you have a theory you say implies the existence of God, you're falling afoul of the scientific method. You know, how can we test for the existence of God?" Langan asked.

Outside of the world of theories, Langan has a wife, Gina, and a farm to run.

"I'm at peace with myself. I actually enjoy my life. We have a lovely place here," Langan said.
