When you make a decision, you need facts. If those facts are in your brain, they're at your fingertips. If they're all in Google somewhere, you may not make the right decision on the spur of the moment.
There's just something hypnotic about maps.
During the whole 'Jeopardy' experience, I felt like I was living a bit of a double life, I would be secretly flying out to L.A. to tape new shows, hoping that none of my coworkers would notice the absence and figure out what was going on. 'Jeopardy' tries very hard to keep their secrets.
Even before you understand them, your brain is drawn to maps.
Being a nerd really pays off sometimes.
