    Health Nerd Retweeted Michael Levitt

    This is very silly. The sample is thrice-selected: a single company, that tested volunteers, and only retested a small subset. A recent large-scale random serosurvey in Tokyo found rates of infection 100x lower than thishttps://twitter.com/MLevitt_NP2013/status/1308979101215096834 …

    If representative as it seems, this antibody survey of 1,877 random healthy people in Japan is a total game-changing event. Read conclusion below: immunity without illness or death!

        The biggest enemy of scientific enquiry is confirmation bias - if you immediately believe things that support your argument you are bound to be wrong quite a lot

        can you link to the large random serosurvey in Tokyo? how do you get almost 50% seroprevalence in ANY group in Tokyo given the low number of cases detected? There must be more going on here than the fact that these were workers at 1 company. I mean...was it a meat-packing plant?

        It was only people who volunteered at that company. And only a small subset of those people. It's phenomenal that a serious scientist would present this "finding" as if it were meaningful. But then, maybe Levitt isn't a serious scientist anymore.

        But if seroconversion is shorter-lived than we thought (they mention some reverted during the study), are many studies just missing the window?

        Indeed, though I would say "detectable seroconversion with current AB tests".

        Replying to @GidMK

        Is it just me or is it odd how vague they're being about the company from which this sample is taken? I'd understand if they don't want to/aren't able to name the company, but knowing the general industry (are most workers public-facing or isolated in offices?) seems relevant!

        Also, did they do any checks to ensure that their sample was even representative of the company's workforce? The results would be pretty useless if the sample greatly overrepresents cashiers or waiters or other customer service workers over office workers, for example

        You are omitting that whole it’s a single company the people come from different, not connected, branches in Tokyo. That the test kit has very high sensitivity and specificity. That being said, I agree there are some flaws, but the way you are dismissing it shows the same bias

        Re: "A recent large-scale random serosurvey in Tokyo found rates of infection 100x lower than this" Yup. It's a problem, as pointed out in the paper you co-authored, with respect to hospitals and outpatient clinics. https://twitter.com/AtomsksSanakan/status/1286196692677799936 … https://www.medrxiv.org/content/10.1101/2020.07.23.20160895v4 …pic.twitter.com/xxOwaGMaFu
