Social psychologists believe the bystander effect can apply to a number of everyday situations.For example, on a busy sidewalk,you might not give momey 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.
