#33I guess Monte Carlo simulations weren't well-known or easily accessible back then? It would have been the perfect way to shut up her critics.

#34So this is at least in part about the "Monty Hall Problem" and why it's solution not intuitive. The article missed an important angle: when the host opens a door, he's giving you more information , which explains why it's better to switch. If you're the host, you need to know which door the car is behind to do your job 2/3 of the time, to avoid revealing it. It's this quality of unexpected information exchange that I…

You can't fight fire with fire, but you can fight Monty with Monte. :-)

#39Which public intellectual introduced Monty Hall to the public when awareness of the problem was at a similar low, and received the fewest incorrect responses?
