I guess there are several ways to think of both: Flatland as described at normaldeviate.wordpress.com talks about the best place to look for a treasure, so in that way it is also about optimal strategy. And Monty Hall is about updating a prior belief about where the prize is, so (in my mind at least) they are both about priors and also both about optimal strategies.

It reminds me of the Monty Hall paradox, because something that seems like it shouldn’t affect a probability (for Monty Hall, opening a curtain, for Flatland, the final state) has a huge effect. In Monty Hall, you should switch because you probably picked wrong at first. In Flatland, you should backtrack to find the treasure because you probably didn’t just backtrack – going, burying the treasure, then backtracking is less likely than just having gone without backtracking. It took me a long time to understand Monty Hall, and a long time to understand this too. In both cases, running simulations helped me understand.
