Social psychologists believe the bystander effect can apply to a number of everyday situations.For example, on a busy sidewalk,you might not give money to a homeless man (or help someone who falls down). On a crowded subway, you may not give up your seat to an elderly person. On the highway,you might choose not to stop and help someone change a flat tire. In these situations,you-and the other bystanders-feel less responsible because so many people are around to help,so no one ends up helping at all.
