A third of adults believe COVID-19 vaccines caused thousands of sudden deaths: poll (2)

27 August, 2023

I would be very cautious about the results of this pool about which I have two methodological concerns. [ https://thehill.com/policy/healthcare/4162874-a-third-of-adults-believe-... ]

Out of the 2,007 people included in the panel, 1,445 answered an online questionnaires. This people were recruited through mails and a good number of studies have shown that people believing in conspiracy theories are much more using the internet to propagate their beliefs than other people do. Therefore, there is a major bias in the recruitment of the panel. The second concern is about the questions. It has been demonstrated that the very fact of reminding a rumor makes some people believe this rumor that they had forgotten or not paid much attention to.

Best regards,
