Bystanders will intervene in nine-out-of-ten public fights to help victims of aggression and violence say researchers, in the largest ever study of real-life conflicts captured by CCTV. The findings overturn the impression of the "walk on by society" where victims are ignored by bystanders. Instead, the international research team of social scientists found that at least one bystander - but typically several - did something to help. And with increasing numbers of bystanders there is a greater likelihood that at least someone will intervene to help. A team of researchers from the University of Copenhagen, the Netherlands Institute for the Study of Crime and Law Enforcement and Lancaster University examined unique video recordings of 219 arguments and assaults in inner cities of Amsterdam (Netherlands), Lancaster (UK) and Cape Town (South-Africa). Lead author Dr Richard Philpot ... said: "According to conventional wisdom, non-involvement is the default response of bystanders during public emergencies. Challenging this view, the current cross-national study of video data shows that intervention is the norm in actual aggressive conflicts. The fact that bystanders are much more active than we think is a positive and reassuring story for potential victims of violence and the public as a whole." The research further showed that a victim was more likely to receive help when a larger number of bystanders was present.
