[UPDATE, added 15 June 2004: This page has been linked in some prominent places recently, and as a result I've received many submissions for inclusion in The Two Things List. Although I can't respond to everyone individually, I want to thank you all for your contributions. I hope that I will be able to update the list to include the new submissions sometime in the near future.]

A few years ago, I was chatting with a stranger in a bar. When I told him I was an economist, he said, “Ah. So… what are the Two Things about economics?”
“Huh?” I cleverly replied.
“You know, the Two Things. For every subject, there are really only two things you really need to know. Everything else is the application of those two things, or just not important.”
“Oh,” I said. “Okay, here are the Two Things about economics. One: Incentives matter. Two: There’s no such thing as a free lunch.”
Ever since that evening, I’ve been playing the Two Things game. Whenever I meet someone who belongs to a different profession (i.e., a profession I haven’t played this game with), or who knows something about a subject I'm unfamiliar with, I pose the Two Things question. I also posed the Two Things question on my blog, where it elicited many responses in the comments section and on otherblogs. This page is a collection of responses to the "Two Things" question, collected from various pages on the web, with credit given when possible.
