Objective: This study assessed whether college students felt less safe or were less likely to work with another student when they thought the person they would work with was carrying a handgun than when they did not. Participants: Seventy participants were recruited from a public US university where campus carry was legal. Methods: Participants were led to believe a confederate was carrying a handgun or not. Participants' perceived safety and willingness to work with others was assessed. Results: No difference was found in participants' perceived safety. Participants who believed another student was carrying a concealed handgun reported they would be less likely to perform certain tasks with the handgun carrier than they would with the non-carrier. Conclusions: People do not feel less safe around a handgun-carrying confederate and that allowing concealed handguns on campus might affect handgun carriers' interpersonal interactions with others in suboptimal ways.
