"After choosing 25 well-known college towns that meet our benchmarks, we ranked them, using four criteria.
- Bachelor's degrees per capita for the over-25 population: this measured the relative education of permanent residents.
- Graduate degrees per capita for the over-25 population: similar to above, but more stratified.
- Median SAT score for the town's student population.
- Voter turnout in the 2008 election: political engagement, whether left or right, has repeatedly correlated with higher intelligence; our one criteria that measures behavior, rather than achievement."
