A 14-week study, funded by Wrigley and led by Craig Johnston at Baylor College of Medicine, found that the students who chewed gum during math class scored higher on a standardized test and got better grades than the non-chewers.
"For the first time we've been able to show in a real-life kind of situation that students did perform better when they were allowed to chew," said Gil Leveille, executive director of the Wrigley Science Institute.
So this opens up all sorts of questions. Like, what's the smartest flavor? My money's on Doublemint.
