Well, obviously it’s cherry-picked. It’s an example of something that challenges my intuition. Most things align with my intuition because I’m in my late 30s and have seen enough of the world to have a fairly good idea of the rough numbers. Here’s another one: the London Underground is older than the telephone.

There’s a light board game called Timeline where you have stuff like this and there are so many surprises. Temporal stuff is hard to reason about and the game catches that. But with large numbers one loses intuition easily: NYC’s subway vs. all domestic and international US air travel is closer in total passengers than one would think. The median American did not fly last year.

Stuff like this. It’s just Gladwell-fodder but numerically fun.
