Where to go for dinner  

If you and your friends are having difficulty agreeing on where to go for dinner, maybe you can use the method championed by one of my professors last quarter. The basic gist is that each member of the group narrows the pool of restaurants by some factor until only one is left. This might seem like a pretty obvious mechanical structure, but supposedly it sets the probabilities that any individual's favorite restaurant will be picked equal.

Of course, it's an a priori assumption that diners face a veil of ignorance with respect to others' preferences, which probably means you can't go out to eat with your friends! And it's not going to get you past Arrow, if you're concerned about such things. [via Gapers' Block]
