The world will end in 2012. Or not.

We were debating healthcare reform with our brother-in-law over an early turkey dinner tonight when we realized ... two intelligent people with the same set of data can come to two vastly different conclusions, just as the well-educated policy wonks on Fox News and MSNBC could all be Mensa members and still yell at each other. Humans aren't really clear judges of the world after all, since some other combined forces of genetics, training, environment, education, culture or homophily warp our conclusions. We all have access to the same mental inputs, yet Republicans and Democrats, or Americans and the Taliban, tend to fall into polarizing we're-right-and-you're-not camps. Every culture that has ever gone to war with another has firmly believed they were backed by God.

We can't all be right. It's confusing. So we leave you with two looks at the end of the world in 2012.
