Comment by Anon Rationalist on Marriage, the Giving What We Can Pledge, and the damage caused by vague public commitments · 2022-07-13T07:40:23.288Z · LW · GW

From my current understanding, there is so much more going on in a marriage ceremony that is worth mentioning here. A carefully designed, meaningful, public ritual seems to be a huge way that humans reinforce their sense of what they value & what their life narratives are about.

Relevantly, I would guess that the act of making the GWWC pledge has much less of this positive effect of reinforcing one's values and sense of meaning, and thus is easier to break.
