In 2010, the same year he became principal of J. M. Atherton High School
in Louisville, Kentucky, Thomas Aberli agreed to let his students take
part in something called Green Dot... Students are taught the “three Ds” of bystander intervention: direct, delegate, and distract.
[...] In the largest and longest study of its kind,
researchers studied 26 Kentucky high schools over five years. Half of
the schools used the Green Dot program, and half did not offer any
bystander intervention training. They found that by years three and four
of the study, victimization rates were about 12% lower in schools that
offered the Green Dot program than in those that did not. That
translated to 120 fewer incidents of sexual violence in the third year
of the study and 88 fewer in the fourth year.
