Piliavin's Subway Study: The Basics

Picture this: you're on the New York subway when someone suddenly collapses in front of you. Do you help immediately, or do you wait for someone else to act? Piliavin wanted to understand exactly this scenario, studying bystander behaviour in real-world situations rather than artificial lab settings.

The study used a field experiment design on actual subway carriages with around 4,550 unsuspecting passengers. Four teams of researchers worked together - two women secretly recorded what happened, whilst two men played the roles of victim and potential helper. This setup allowed them to test how different factors influenced whether people would help a stranger in distress.

Four key variables were manipulated: whether the victim appeared ill or drunk, the victim's race (black or white), when a model helper intervened (after 70 or 150 seconds), and how close this helper stood to the victim. The main focus was measuring how quickly and frequently passengers offered spontaneous help.

Remember: This was groundbreaking because it moved bystander research out of labs and into real-world settings where people's genuine reactions could be observed.

The procedure was cleverly simple - victims would collapse 70 seconds after the train left a station, then lie still with eyes open until someone helped them. Between six and eight trials ran daily between 11am and 3pm, creating a substantial dataset about human helping behaviour.
