Remember the right comparison regarding apparent long-Covid: What proportion of people would self-report brain fog and lack of energy anyway, with nothing to do

Remember the right comparison regarding apparent long-Covid: What proportion of people would self-report brain fog and lack of energy anyway, with nothing to do with Covid?

This sort of claim has been made after a study was released that took the presence of SARS-CoV-2 antibodies as the source of thruth for whether people had gotten COVID-19. This sort of claim can’t be made on that basis because a lot of people do not produce antibodies after infection. Paper: “Predictors of Nonseroconversion after SARS-CoV-2 Infection” – https://wwwnc.cdc.gov/eid/article/27/9/21-1042_article https://wwwnc.cdc.gov/eid/article/27/9/21-1042_article Abstract: “Not all persons recovering from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection develop SARS-CoV-2–specific antibodies. We show that nonseroconversion is associated with younger age and higher reverse transcription PCR cycle threshold values and identify SARS-CoV-2 viral loads in the nasopharynx as a major correlate of the systemic antibody response.” Please note that this was already known when the study which is taken to show that people are imagining long COVID was published. It’s not a good study. Quite a bit of research has been done since then which further pins down the fact that long COVID is very real and how to diagnose it with biomarkers, which turn out to correspond very well with people saying that a SARS-CoV-2 infection messed them up. Please also consider how harshly judgemental it appears when someone accuses a large number of people of imagining or making up a severe and disabling condition. You have to be very certain.

How much of everything can be explained by the brain's bias to ignore the base rate fallacy.
