Tight-knit teammates may conform to each other's behavior -- ScienceDaily
After analyzing the data, the researchers found that participants who felt more closely connected to their teammates and identified strongly as part of the team were more likely to engage in risky behaviors like binge drinking, marijuana use and hazing if they believed their teammates were already doing these activities.
Additionally, athletes who belonged to teams that as a whole reported being especially close were more likely to say they would conceal a concussion to remain in play.
Graupensperger said the findings -- recently published in the Journal of Sport and Exercise Psychology -- suggest that teams should try to find positive ways to encourage bonding between players.
"The silver lining is that we did find that conforming does also work similarly for positive behaviors," Graupensperger said. "This finding also generalizes to behaviors like volunteering. So our challenge going forward would be to try to reduce pressures to conform to negative behaviors while still encouraging identifying closely with your teammates."
