Sexual decision making for the "better than average" college student.

Objectives: to examine the impact of downward social comparison and the "known partner is a safe partner" heuristic on college students' sexual decisions.

Participants: One hundred-eighty heterosexual or bisexual undergraduate college students.

Methods: participants read dating vignettes that varied on perspective and familiarity and then rated the likelihood the couple would engage in sexual intercourse and use a condom.
