I wouldn't have thought Tufts would be in the Happiest category.
I'm not. It fits perfectly with cognitive theory. Tufts has a reputation for being a back-up school for those who don't get admitted to the Ivy League. That's not completely fair. There are bound to be many students there who had Tufts as a first choice. Still, I've had two student-led tours there, and both guides spent a lot of time talking about how they were glad to be at Tufts instead of an Ivy League school. The technical terms for that is "protesting too much." ;-)
