旁观者效应：我们为何有时见死不救
The Bystander Effect: Why We Sometimes Fail to Help Others
Most people would like to believe they are compassionate and would step in to help a person in trouble. However, psychology tells us a different story. When emergencies happen in public, it is surprisingly common for people to hesitate or do nothing, especially if they are surrounded by others. This odd behavior is widely known as the "bystander effect."
大多数人都愿意相信，自己是充满同情心并且乐于助人的。当他人陷入困境时，我们也觉得自己一定会伸出援手。然而，心理学却告诉我们，事实并非总是如此。公共场合发生紧急情况时，如果现场有许多人在场，人们反而容易犹豫不决、置身事外。这种看似奇怪的现象在心理学上被称为“旁观者效应”。
Why Do People Stand By?
为什么人们会袖手旁观？
The bystander effect is deeply rooted in human psychology. One key reason is the “diffusion of responsibility.” When many people witness an incident, each individual assumes that someone else will help, so they feel less pressure to act themselves. Ironically, the more people are present, the less likely it is that anyone will step forward.
旁观者效应的本质原因，深深植根于人类心理。最主要的因素之一就是所谓的“责任分散”。当有很多人在场时，每个人都潜意识里觉得“肯定会有人去管”，因此主动出手的压力就减小了。讽刺的是，目击者越多，真正采取行动的人反而越少。
Another factor is social influence or “pluralistic ignorance.” When the situation is unclear, people look to others for cues on how to react. If no one else appears alarmed or is helping, individuals may conclude that intervention is unnecessary—even if someone clearly needs help. No one wants to stick out or overreact, so everyone waits and does nothing.
另一个重要因素是社会影响，也叫“多元无知”。在情况不明时，人们会观察别人如何反应。如果大家都若无其事，对问题视而不见，个人就会误以为无需采取措施——即便明明有人急需帮助。毕竟，没有人愿意显得太突兀或大惊小怪，因此每个人都选择观望，最后就导致无人出手。
Real-Life Examples and Alarming Cases
现实案例与触目惊心的事件
The bystander effect has been observed in both minor daily events and tragic historic cases. One of the most famous examples is the 1964 murder of Kitty Genovese in New York, which led to a wave of psychological research on the topic. It was reported that dozens of neighbors heard her cries for help, but no one intervened until it was too late. Later investigations suggested the story was more complex, but the case became a symbol of public apathy.
旁观者效应既存在于日常的小事件中，也发生在一些著名的历史悲剧里。最广为人知的例子莫过于1964年发生在纽约的基蒂·吉诺维斯案件。据称，当时多达数十位邻居都听到了她的呼救，却没人第一时间出手相助。虽然后来调查发现情况可能没那么极端，但这个案件成为公众冷漠与旁观者效应讨论的典型代表，也直接催生了大量相关心理学研究。
Even outside of emergencies, we see the bystander effect in everyday life: people ignore someone being bullied at school, passengers avoid intervening when witnessing a dispute on public transport, or colleagues remain silent instead of reporting inappropriate behavior in the workplace.
即便不是突发事件，旁观者效应也在我们的日常生活中随处可见——比如同学旁观校园欺凌、乘客在公交车上遇到冲突选择沉默、同事面对职场不当行为选择袖手旁观。
How Can We Overcome the Bystander Effect?
如何克服旁观者效应？
Knowing that these social and psychological forces affect us is the first step to taking action. Experts suggest some practical ways to break this behavior. In emergencies, giving clear and direct instructions can be very effective—for example, looking at a specific person and saying, “You in the blue shirt, please call an ambulance!” This approach focuses responsibility and motivates people to act.
意识到这些社会和心理机制会影响我们，是促使自己采取行动的第一步。专家建议，通过具体指派任务，可以有效打破僵局。在突发事件中，如果我们能直接呼吁，比如盯着身边某个人说：“穿蓝衣服的，请帮忙打120！”，就能大大提高对方的责任感，激发人们马上行动。
Building a stronger sense of community and empathy also helps. If we see strangers as “one of us,” rather than distant outsiders, we are much more likely to offer help. Training and awareness campaigns, such as those for first aid or anti-bullying, can prepare people to recognize emergencies and respond confidently.
此外，增强社区感和同理心也很重要。如果能将陌生人视作“自己人”，而非完全局外人，我们帮助他人的意愿就会提升。平时多接受相关培训和提醒，比如学会急救技巧，参加反欺凌宣讲等，也能让我们遇到紧急情况时更有信心识别和应对。
Why It Matters
为什么旁观者效应值得我们关注？
Understanding the bystander effect not only helps us recognize hidden biases in our behavior, but also teaches us to be more proactive, ethical, and courageous—both for the sake of others and for our own sense of responsibility. After all, sometimes a single small action can create a chain reaction, turning bystanders into helpers and making a real difference in someone’s life.
理解旁观者效应不仅让我们意识到潜藏于自身行为中的偏见，更能激励我们在关键时刻变得更主动、更有道德勇气。毕竟，有时候哪怕只是迈出的微小一步，也会带动更多人加入帮助，甚至彻底改变一个生命的命运。
