Divide the teens into 4 groups of the same gender (2 boy groups, 2 girl groups.) If your group is small, the teens can play individually.
Each group receives a short profile and photo of a boy or girl. (Boy groups read about a girl and the girls analyze a boy.)
The catch is that the profiles of the same person are drastically different. For instance, one girl group sees a picture of an attractive male and reads a description of a well-rounded easygoing person. The other girl group’s profile shows the exact same picture but describes a cheater and felon.
The groups then complete identical questionnaires about the physical appearance of their prospective ‘dates’.
Upon completion, the groups compare their answers and discuss.
