Did you know that women can be pretty and clever at the same time? Scary combination, huh?
Apart from the obvious examples from this thread, here's another one: Marilyn vos Savant. She was listed in the Guinness Book of World Records as having the highest recorded score in an IQ test (228 when she was 10...). Among other things she has been working as a puzzle columnist for a U.S. magazine, and as such was involved in the story of one of my favourite puzzles, which goes like this:
"Suppose you're on a game show and you're given the choice of three doors. Behind one is a car, behind each of the others is a goat. You pick a door, say door A, and the host, who knows what's behind the other doors, opens another door, say B, which has a goat. He then says : "Do you want to switch to door C?" Is it to your advantage to take the switch?"
After having given the answer, vos Savant has recieved more than 10'000 letters about that puzzle, most of them claiming she had been wrong. Here two examples:
"I'm very concerned with the general public's lack of mathematical skills. Please help by confessing your error. . . ."  Robert Sachs,Ph.D., George Mason University
"You blew it, and you blew it big!. . . You seem to have difficulty grasping the basic principle at work here. . . There is enough mathematical illiteracy in this country, and we don't need the world's highest IQ propagating more. Shame!" Scott Smith, Ph.D., University of Florida.
Quite funny, because her anwer had been correct of course (when assuming that the game host always opens a door with a goat among the two remaining doors). Any ideas, is it better to switch, to keep the first door you picked, or does it not matter?
