If you live in the same place where you grew up, you're not alone. A new study suggests your decision about whether to stay or go, may be driven by your intelligence level. ABC News reports the smarter you are, the more likely you are to move out of your hometown, according to a new study on American mobility. University of Helsinki researchers found that people who move out of rural areas and end up in cities have the highest IQ levels. A Pew Research study found the top reason people cited for moving was economic opportunity, while the people who stayed most often sited family bonds, and the strength of their home connections. More than half, 57 per cent, have never lived outside their home state and 37 per cent have never left their home town.
