There is some disagreement when it comes to the world’s highest IQ.  Marilyn vos Savant is an American magazine columnist, author, lecturer and playwright.  It is Marilyn vos Savant that has the highest IQ according to Guinness.  Her IQ is 228; however, the test that resulted in this score was taken b Marilyn at the age of 10.  Eight months later she took another IQ test and this time scored 167+.   Guinness retested Marilyn in the mid-1980s and on that test she scored about 186, which is still very good.  A score of 186 is in the 99.999997 percentile, or about 1 in 30,000,000.

It was Marilyn vos Savant who made The Monty Hall Problem controversy.  The Monty Hall Problem (named because it sounds like a game show scenario) is as follows: Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?

It seems like the logical way of thinking would lead you to believe there is a 50/50 chance of winning the car if you switch or stay with your original door.  Marilyn vos Savant claimed that there was a 2/3 chance of winning the car if you switched.  Letter poured in to her claiming she was wrong, but indeed she has been proven to be right, there is a 2/3 chance of winning the car if you switch doors and a 1/3 chance of winning the car if you don’t.  The easiest way to explain why this is so is simply because when you originally picked your door you had a 2/3 chance of picking a goat.  So if one goat is gone and it is 2/3 likely that you have selected a goat switching the door would give you only a 1/3 chance of picking a goat and thus a 2/3 chance of winning the car.  Genius at it’s best.

There is one man who supposedly has a much higher IQ than a mere 228.  William James Sidis’s IQ is estimated to be between 250 and 300.  This has never been confirmed however.  If you want to learn more about Sidis check this link out.
