At what IQ level does this make sense? Seems like once the goat is revealed in one of the three doors, it would be 50/50 whether the car was in one of the two remaining doors or the other.
But apparently not- really smart bros say it makes sense to change your guess:

Many readers of Savant's column refused to believe switching is beneficial and rejected her explanation. After the problem appeared in Parade, approximately 10,000 readers, including nearly 1,000 with PhDs, wrote to the magazine, most of them calling Savant wrong.[4] Even when given explanations, simulations, and formal mathematical proofs, many people still did not accept that switching is the best strategy.[5] Paul Erdős, one of the most prolific mathematicians in history, remained unconvinced until he was shown a computer simulation demonstrating Savant's predicted result.

If this only makes sense at extreme IQ levels, it's one of the best tests for such extreme IQs that I've seen. I simply don't get it, even as explained in your Wiki link. |

then he opens one door with a goat so now you are making a choice knowing it's 50/50 which is better than 1/3 |

On the 2nd pick "switch" u get a 1/2
Ur insane if u dont change it to a 50/50 by changing doors, ur basically assuming u won a 1/3 off the bat (insane)
just switch |

The way the Monty Hall problem is explained to people that can't understand it is if there were a 100 doors and the host closed 98, switching becomes obvious because you know you only had a 1% chance of picking correctly initially. But if that was still only 50/50 it makes no sense why 100 doors is such an obvious switch. With 100 doors you intuitively understand that switching is a far greater chance that switching is superior to staying (99%). The same is true with 3 doors. |
