And timely update from Dr. Campbell re bad science continually being spouted by media so they are first to press on it.
In this, he talks about the "levels of scientific evidence" (of which most of the info out there is the bottom most level or not even good enough to get on the scale!) Not only journalists, but scientists are doing "click bait" and he discusses such and reasons why.
I = Meta analyses or RCT with clear cut results
II = Small RCT with unclear results
III = Cohort or case control study
IV = Historical cohort of case-control studies
V = Case series studies with no controls
In this one, he talks about the "science research" shows that depending on who you listen to, asymptomatics are 5%-80%...
It takes effort to skip the media reports, and train to go to the original paper to evaluate what level of scientific evidence (credibility) should it be given, and if peer reviewed or just put out on a pre-print site which now exists during this pandemic so they can say their efforts were cited and get a "feather in their academic hat"

ETA: And then you have company after company doing press releases all over the place speaking to they have the cure! Pfffft.
There aren't many that can read and understand in the general public the science, and do critical thinking. Most media and others don't even make a veiled attempt to cite the original scientific paper....either because there isn't one and it's just quoting an opinion... or the just aren't true scientists.. they are journalists who are depending on those with an agenda.
