A selection effect would account for the fact that teens tend to choose friends who share their interests and behaviors. Therefore, it is possible that teens who smoke are more likely to befriend other teens who smoke, rather than being influenced by their peers to start smoking. Understanding this selection effect can help us avoid overestimating the impact of peer pressure on teens' smoking habits.
