We didn’t dwell on the minimum plausible number (as noted above, the main thrust of the post is that estimates should be lower than previous estimates, and I think a variety of values below around 2% are plausible).
That said, 0.1% strikes me as too low, since it implies a very low ratio between the number of people who’ve heard of EA and the number of moderately engaged EAs. i.e. this seems to suggest that for every ~50 people who’ve heard of EA (and basically understand the definition) there’s 1 person who’s moderately engaged with EA (in the US). That would be slightly higher with your estimate of 0.3% who’ve heard of the movement at all. My guess would be that the ratio is much higher, i.e. many more people who hear of EA (even among those who could give a basic definition) don’t engage with EA at all, and even fewer of those really engage with EA.
We’ll probably be going into more detail about this in a followup post.
Thanks for the reply!
