Hmm, I wonder if they attempt to control for bias. It sounds as though they were asking random passersby if they wanted a COVID-19 antibody test. If so, it seems that the sample group could be biased toward including more people who suspected that they may have been infected (previously or currently) than a truly random sample.

Change in Human Social Behavior in Response to a Common Vaccine https://pubmed.ncbi.nlm.nih.gov/20816312/ https://pubmed.ncbi.nlm.nih.gov/20816312/ Conclusions: These results show that there is an immediate active behavioral response to infection before the expected onset of symptoms or sickness behavior.
