What's the benefit to calling the police after turning a corner? They're not going to get there in time to stop the crime, and there's really not enough evidence to track the criminal down. I'd have to wait for the police to get there and then give a witness statement. In this scenario, I assume I have something better to do than waste an hour of my time with police when they won't solve the crime anyway.
This line of logic has some merit. A lot of times, situational details, such as time, are a lot more important than a person's personality, morals, etc.
Darley and Batson's "Jerusalem to Jericho" experiment looked at how situational details affected the behavior of seminary students confronted with a 'Good Samaritan' situation. (The link is just a summary of the experiment since you have to pay to look at the actual report.)
The students were notified that they had to deliver a speech in a different building on short notice. Along the way, they would passed an obviously injured man in great pain lying across the corrider they had to walk down (whether the injured man was an actor or whether Darley and Batson actually beat someone up and tossed them in the corridor isn't noted). Surely seminary students would put helping the injured man ahead of delivering their speech, but ...
The urgency of the short notice was varied:
In one group, the students were told they were already late and they needed to get there as soon as possible. Only 10% of those seminary students stopped to help the man.
In a second group, the students were told the assistant was ready for them and they could give the speech as soon as they arrived. 45% of those seminary students stopped to help the man.
A third group was told that it would be a little bit before they assistant was ready for him, but he should head over now, anyway. 63% of those seminary students stopped to help the injured man.
In other words, the urgency of their own personal situation affected whether they felt they could spare the time to help the injured man. That resulted in a bigger difference in responses than the topic of the speech, which was the other variable:
Half the students in each group had to give a speech on the potential careers for seminary students. In all, 29% of those seminary students stopped to help the injured man.
Half the students in each group had to talk about the Good Samaritan parable. 53% of those seminary students stopped to help the injured man.
In fact, there were a few seminary students in the urgent group that were in such a hurry to give their Good Samaritan speech that they stepped directly over the injured man on the way to their speech. One can only wonder if they suddenly realized the irony in the middle of their talk and how they reacted.
Overall, 40% of the seminary students were good Samaritans and helped the injured man.
