Arguably the most fascinating thing about the Monty Hall problem is that although this solution is extremely widely known in academic circles, the game is still played today on Let's Make a Deal! in the exact same way: three doors, pick one, a Zonk is revealed behind another, switch or keep? (Although there is one variable I don't know the answer to: I don't know if they always give you the offer to switch. Sometimes I believe it's a different offer, "Keep the door or take this money out of my hand". The host being able to choose which offer is made shifts the odds a bit, because the host may be choosing the offer based on whether you've picked the right door initially, and may be making that choice in a biased or randomized way. There's hidden data there we don't have as observers).
