Over the weekend I had my own experience with the bystander effect and I will recall the event with reference to Darley & Latane's Multi-stage Model.
On Saturday night my family and I noticed a disturbance (Stage 1- noticing the event). There were a few people outside of one house, however there was no one inside. The three males outside proceeded to destroy the letterbox, tried to kick the door open and attempted to jump over the fence into the backyard (Stage 2 - interpreting the event). The immediate neighbours to the house were drawn out of their home by the racket.
My mother and I talked about calling the police, however my brother stated that the people who were ouside watching on had probably already called the police. Therefore he assumed no personal responsibility to take any action as someone else would do it(bystander effect). However, after reading about the bystander effect I encouraged mum that we probably should still call the police (Stage 3-personal responsibility). I rang and recalled the details to the police and they said they would send a car around to check (Stage 4 & 5- deciding to act and acting).
I have previously become a bystander who does not intervene but after this assignment I am beginning to change my ways.
