Our respondents also look about 2x more likely than EA Survey respondents to have been introduced via a class at school, though I’m not sure how much of this is noise. (4% of our respondents gave this answer, vs. 2% for the EA Survey.)
For reference, I think the 95% CI for your figures would be about 2.1-7.7%, and 1.3-2.5% for the EAS.
Doing a quick eyeball of the two [OP and EAS] charts, they look pretty similar insofar as they’re comparable. “Peter Singer’s work” doesn’t appear, but it’s because they didn’t have that category — that would fall under “Book, article, or blog post” or “TED talk.” “Personal contact” leads in both, though by somewhat more in ours.
Notably, if we look at the EAS open comment data which I mentioned here, we can see that when Peter Singer references are counted as a single category, he’s among the top-mentioned. 80,000 Hours don’t appear among the top mentions in this analysis, most likely because they were a fixed category and respondents didn’t feel the need to select 80,000 Hours and then write “80,000 Hours” in the further details box (personal contacts and EA groups often appeared in the further details of other categories, in contrast).
