Honey, It's Not My Fault—My Nucleus Accumbens Made Me Buy That HD TV

John Tierney, estwhile New York Times columnist (and occasional Reason contributor), has been promoted to science columnist. He launches his debut column in today's Science Times where he subjects himself to an MRI to look deep within his brain to find out why he is a spendthrift. It turns out that spending money makes him feel good. His new blog, TierneyLab links to a Carnegie-Mellon University survey that helps you determine if you're a tightwad or a spendthrift.

I've just taken the survey, but given my credit card debt, I think I already know which way it's going to come out. Damn my pleasure besotted nucleus accumbens!
