@TheZvi Yeah, that long COVID survey had all sorts of signs of response bias. ~2/3 of respondents with a symptomatic infection were female. Also older, higher socioeconomic status. Also, people with COVID were much more likely to respond than control group. Bad use of polling. https://t.co/iIiIhny6kr — PolitiTweet.org
