实际情况是大家都不屑于聚拢了来看看发生了什么，看见的也当没看见，大家都不关心不在乎甚至不好奇。这个比大家都围拢了来看而无动于衷还要等而下之。

The bystander effect or Genovese syndrome is a social psychological phenomenon that refers to cases where individuals do not offer any means of help in an emergency situation to the victim when other people are present. The probability of help has in the past been thought to be inversely related to the number of bystanders; in other words, the greater the number of bystanders, the less likely it is that any one of them will help. The mere presence of other bystanders greatly decreases intervention. This happens because as the number of bystanders increases, any given bystander is less likely to notice the incident, less likely to interpret the incident as a problem, and less likely to assume responsibility for taking action.[1]
