A study comparing narrative vs. philosophical arguments about charity finds that the former increase giving (and allocations for international giving) while the latter don’t. Authors conclude this is “preliminary evidence that exposure to at least one type of narrative influences charitable giving, motivation, and opinion, while exposure to one common type of philosophical argument has little if any influence.”
We’re planning to do some followup studies to dig into the generalization question. We want to see if the results hold across different arguments, narratives, charity choices, etc.
