    It never ceases to amaze me how many people seem blithely unaware that an inherent property of meta-analyses is: Garbage in, garbage out. Meta-analysis does not correct bias; it smooths out random errors. You can't turn a bunch or turds into gold through meta-analysis.https://twitter.com/mjaeckel/status/1416747673990926341 …

    A brain completely broken by Bret Weinstein and Heather Heying’s nonsense. Has a math degree, but believes a meta analysis that includes questionable studies is “better and more reliable” than RCTs, particularly for “most things medical”. pic.twitter.com/o703Hp2dfc

        I mean, these are people who should know better, a disturbing number of them scientists and doctors.

        They also don't seem to understand that meta-analysis, but its very nature, includes a number of judgment calls in deciding which studies to include and ranking their rigor (i.e., risk of bias). Methods matter. A lot.

        The brutal rebuttal. I may be “childless”, but at least I know why meta analyses are only as good as the studies you use, and I am not taken in by anti-vaccine charlatans and rightwing grifters. 🤷‍♀️ pic.twitter.com/nY1JBKgZ1d

        I had hoped this particular individual knew as much because she’s employed as a data scientist. A clear example of the damage caused by Weinstein’s disinformation campaign.

        Although as far as the second tweet is concerned, that's generally correct, with the caveat that "generally" is doing a ton of work there.

        GIGO: Garbage In, Garbage Out This is a limitation I try to teach. We need to critically appraise the methodology of a SRMA. Also, look at the included studies. These can threaten the validity and conclusions of a meta-analysis.pic.twitter.com/NMHQH24yrj
