Matt Damon, 160
Matt Damon may have played an unrecognized genius in Good Will Hunting, but it seems he’s a genius in real life. With an IQ of 160, Damon attended Harvard University, where he discovered a love of writing. Damon is also now a representative of Feeding America, a famine relief organization, and the founder of the H2O Africa Foundation, the nonprofit arm of the Running the Sahara expedition, which joined forces with WaterPartners in July 2009 to create Water.org.
