I currently work for the CEA University Groups Team whilst completing my undergraduate degree in Philosophy at the University of St. Andrews.
EAs inflect upwards with their intonation. I think this is used to signal uncertainty and epistemic humility. However, it's often excessive and highly noticeable to non-EAs; I saw my family for the first time in six weeks, having been in Trajan during this period, and they highlighted this change in my voice (with much mockery). I thought it might be worth noting for those that aren't aware : )
Part of me thinks we should spend years reflecting on lifelong decisions before making them; hence, we ought not encourage young people (e.g., university students) to sign the GWWC pledge.
However, a bigger part of me thinks locking in altruistic desires to mitigate future selfishness is *exactly* what we should be doing. Some argue that we shouldn't make life-long decisions as young people because our preferences and values may change. Yet, to me, this is all the more reason to take the GWWC pledge; it is precisely because our altruistic tendencies might weaken that we should lock those values in. I want to do things that increase the likelihood of future-Sam still wanting to help others as much as current-Sam.
Separately, starting to donate when you're young can make the process much easier! I began giving 10% when I got my first job at 16, and it has never felt aversive or difficult. I don't think "I've earnt £100, so now I have to give up £10", instead, I just view it as earning £90. I imagine that if I started this practice aged 40, I would long for that extra £10 much more.
