Wait, all of academia is a 'narrow interest' in the eyes of your average person? Does the average person chunk people into two groups, 'those who seem like they read Wikipedia for fun' and 'normal folk'? That's a scary thought. It'd be really cool if someone ahem Michael Vassar ahem wrote a 'The World is Mad' post and followed it up with an analysis of why the world is mad: what you would expect of a world predominately run by IQ 120 people with an average age of 55 or so, elected by a populace who largely categorize the things they see in the world as either good or evil.
