The Good Samaritan Experiment

The famous Darley-Batson experiment (Darley, J. M., and Batson, C.D., "From Jerusalem to Jericho": A study of Situational and Dispositional Variables in Helping Behavior". JPSP, 1973, 27, 100-108.) Its conclusion is that if people are in a hurry, they help a lot less, but being on the way to preach on the parable did not, but it looks to me as if this second conclusion is wrong, given the data, so do not rely on it.
