I read "Psychological barriers to effective altruism: An evolutionary perspective" by Bastian Jaeger and Mark van Vugt This is relevant to my own related synthesis project "Increasing effective charitable giving: The puzzle, what we know, what we need to know next", a web-book in progress. The paper an interesting perspective and a good take. I'm a bit skeptical of the strength of some of the empirical evidence and the way results are stated in Psych papers and syntheses. I read some of the cited evidence, and go off on copious tangents. If you read the paper at https://www.sciencedirect.com/science/article/pii/S2352250X21001779 and install the https://hypothes.is/ plugin, you can interact with my comments within the paper itself. --- Send in a voice message: https://podcasters.spotify.com/pod/show/david-reinstein/message
