This is a study from Berkeley. It confirms what I've long suspected.

Highly religious people are less motivated by compassion than are non-believers

Study finds highly religious people are less motivated by compassion to show generosity than are non-believers

In three experiments, social scientists found that compassion consistently drove less religious people to be more generous. For highly religious people, however, compassion was largely unrelated to how generous they were, according to the findings which are published in the most recent online issue of the journal Social Psychological and Personality Science.

The results challenge a widespread assumption that acts of generosity and charity are largely driven by feelings of empathy and compassion, researchers said. In the study, the link between compassion and generosity was found to be stronger for those who identified as being non-religious or less religious.

'Overall, we find that for less religious people, the strength of their emotional connection to another person is critical to whether they will help that person or not,' said UC Berkeley social psychologist Robb Willer, a co-author of the study. 'The more religious, on the other hand, may ground their generosity less in emotion, and more in other factors such as doctrine, a communal identity, or reputational concerns.'
