I'm glad someone asked this, so I could finally end with a plug that doesn't mention my books. Half the human's winnings go to charity in these matches--and all of Watson's winnings, since I presume it doesn't have a mortgage to pay like Brad and I do.

It took me agonizing weeks to pick a charity, but once I started talking to the folks at VillageReach, I knew I was on the right track. It's a Seattle-based nonprofit that works on getting medical supplies like vaccines to the most remote parts of the world--not just Mozambique, but the teeny middle-of-nowhere village in Mozambique, which is apparently the hard part of the equation.

It's undeniably worthy work, and it's slightly wonkish, which seemed Jeopardy-appropriate. The GiveWell philanthropy index rates them as the nation's top charity when it comes to effectiveness and transparency. They estimate that VillageReach saves another child's life every time you donate just several hundred dollars. How could I say no?

If anyone has a few bucks to spend, or is going to be playing a quiz show against a super-intelligent robot anytime soon and needs to select a charity, I highly recommend the fine folks at VillageReach.
