“友谊悖论”（最早由费尔德在1991年提出）指的是这样一个事实，即平均而言，人们的朋友比他们的朋友要少。我表明，这种对更受欢迎的人的过度抽样可以导致人们感知到比总体人群中存在的更多的参与。这一反馈放大了参与涉及互补性的行为。此外，对某一行为有最大倾向的人会选择最多的互动，从而导致进一步的反馈和放大。这些结果与研究发现高估了酒精，香烟和药物的同伴消费以及由此产生的高水平药物和酒精消费相一致。
The “friendship paradox” (first noted by Feld in 1991) refers to the fact that, on average, people have strictly fewer friends than their friends have. I show that this oversampling of more popular people can lead people to perceive more engagement than exists in the overall population. This feeds back to amplify engagement in behaviors that involve complementarities. Also, people with the greatest proclivity for a behavior choose to interact the most, leading to further feedback and amplification. These results are consistent with studies finding overestimation of peer consumption of alcohol, cigarettes, and drugs and with resulting high levels of drug and alcohol consumption.
