Suicide rates are higher at high altitudes; some hypothesize that hypoxia is the cause. We examined 8,871 suicides recorded in 2006 in 15 states by the National Violent Death Reporting System, with the victim's home county altitude determined from the National Elevation Dataset through FIPS code matching. We grouped cases by altitude (low less…

According to the "acting White" hypothesis, African American students who do well in school are negatively sanctioned by their peers, leading them to withdraw future academic engagement.
