If you take the current GWWC pledge to literally require supporting interventions in developing countries, then that’s not something that a cause-agnostic donor should be willing to agree to early in their life
I guess that in this community we have people who think that they will live a long time. They might think of “early in life” as 200 years.
A pledge is a commitment device. A person who is currently donating X to Xrisk might increase their chances of continuing to donate to Xrisk by taking the pledge.
I don’t see how that’s not behavior change.
