Original result
Of those in no hurry, 63% stopped to help; with a little hurry, 45%; in a big hurry, only 10%. The talk topic made almost no difference: some students on their way to speak about the Good Samaritan literally stepped over the man.
What we know today
This was a single study with a small group of students, so the percentages should not be read as precise figures. Its main idea, that the situation of the moment can matter as much as character, is still one of the most debated ideas in social psychology.
The surprising part
Even people on their way to talk about compassion did not see someone who needed help when they were in a hurry.
