Bar chart
Share of bogus respondents by sample source
How often fake or careless answers got into online polls, by how people were recruited
A bar chart from Pew Research Center's 2020 study of bogus respondents in online polls: 7% of a crowdsourced sample, 5% of opt-in panels on average and 1% of address-recruited panels. It is useful for founders and researchers deciding how much to trust people recruited from open online channels. Koji uses it in a playbook on screening customer interview recruits from Reddit and online communities.
