It only asked me for my name (not citizenship, residency, or address), so not sure if they cross check with a citizens directory or something, but the UK didn't require citizenship to answer a public consultation on the kinds of causes their international aid should go towards so it seems like they just allow anyone to give input.Â
Just sent a letter. This post was what pushed me to do it-- I am a CA voter and have never written a letter urging the governor to take action on legislation before, and I believe I wouldn't have done so without 1. reading this post and 2. reading Will MacAskill's comment on this post. So that's counterfactual impact on your part, nice one!
I get updates from all these lists emailed to me, and the EA Opportunities Board is one of my favorites because it often has part-time opportunities (eg fellowships, courses, part time work) which I think don't make it into some of the other lists' headlines (either because the opportunity is small, or too EA-niche). Just my two cents.
