NC State researchers have concluded something fascinating about the incidence of traffic fatalities after sporting events.

The researchers found that traffic fatalities increased significantly after close games, and that games which were rated as nail-biters were far more likely to result in traffic fatalities than blow-outs.  Each increase in the closeness rating was associated with a 21 percent increase in fatal accidents at the game site. To go from a blow-out to a nail-biter resulted in a 133 percent increase in observed fatal accidents.

Furthermore, researchers found that the increase in fatalities occurred only in places where there were winners – the site of the competition and the hometown of the winning team. “This pattern of results is important in that it suggests that the cause of the relationship might be associated with competition-induced testosterone,” Wood says.
