Marcus conducted an experiment to investigate public perceptions of adolescent deviance. He recruited participants from a local community center and presented them with two different scenarios describing a 16-year-old high school student.
In the first scenario, participants rated how likely it was that the teenager had committed physical vandalism (Condition A). In the second scenario, the same participants rated how likely it was that the teenager had committed online copyright piracy (Condition B).
The participants provided a rating on a scale from 1 to 10, where 1 represented 'highly unlikely' and 10 represented 'highly likely'.
