Editing Bystander effect (section)

====Ambiguity and consequences====
Ambiguity is one factor that affects whether or not a person assists another in need. In some cases of high ambiguity, it can take a person or group up to five times as long before taking action than in cases of low ambiguity. In these cases, bystanders determine their own safety before proceeding. Bystanders are more likely to intervene in low ambiguity, insignificant consequence situations than in high ambiguity, significant consequence situations.

Latané and Rodin (1969) suggested that in ambiguous situations, bystanders may look to one another for guidance, and misinterpret others' lack of initial response as a lack of concern. This causes each bystander to decide that the situation is not serious.<ref name=Meyers/>
