One question that I'm curious about with respect to EA strategy is the extent to which people are or are not willing to change not just specific organizations they might donate too, but overall cause areas that they consider important focuses. I'm especially interested in "average donors" and people who are not necessarily explicitly EA -- I think this question is quite meaningful with respect to what kinds of outreach most generate value in the world.
Is there any research into this topic people could point me to, either from within the EA community or elsewhere?
There are some studies suggesting people sometimes donate to less effective charities even when informed that other charities are more effective. E.g. this paper found that people prefer to donate to cancer research even when told that arthritis research is more effective. We made similar findings in this paper.
These papers just ask one-off questions, though - they don't concern whether sustained persuasion would cause people to change cause area. But they do indicate that preferences for particular cause areas often override effectiveness information.
Thanks! Good to know.
