It is well known that teenagers take risks—and when they do, they like to have company. Teens are five times likelier to be in a car accident when in a group than when driving alone, and likelier to commit a crime or drink alcohol when with a group of peers.
Now, a new study from Temple psychologists Laurence Steinberg and Jason Chein, CLA '97, has found that an inclination toward risky behavior in groups also holds true for another teen mammal—namely, mice.
