  • COVID was more infectious than things like flu, and people who avoided the vaccine typically also were more likely to break lockdown and social distancing rules, so the r value managed to be close to/above one just from unvaccinated people (or people whose vaccines were for earlier strains) passing the virus on to other unvaccinated people. Breakthough cases obviously make things worse, but when one unvaccinated person typically passes it on to at least one other unvaccinated person, even if vaccinated people never got COVID again, it would still have stuck around, and that’s not the vaccine’s fault. A virus won’t go away until the r value is below one in all subpopulations.

    The figures for effectiveness that were around 90% weren’t for getting the virus and passing it on, they were for getting enough of the virus to show symptoms, which for COVID, is more (hence why people kept spreading the virus and thinking they were fine). For a standard vaccine like an annual flu jab, that figure would only be around 70%. The figures that were around 99.99-100% were for effectiveness against serious infection needing breathing assistance. E.g. of the first 100,000 people in the AstraZeneca study, none of them needed breathing assistance from a COVID infection from the early strains that the initial version of that vaccine protected against. There’s never been a flu jab that effective.



  • You don’t hire the writers because they’re lazy, you hire them because they’re cheap and you want to minimise production costs because there are women in the film so you’re not expecting to sell any tickets except to people who’ve fallen for the social media marketing campaign you ran that said anyone who doesn’t watch the film is a misogynist. It’s just classic race-to-the-bottom profit seeking.

    Your if it fully worked, the virus would have died out idea would only work if everyone in a population got vaccinated and that population didn’t have any contact with anywhere else where some people weren’t vaccinated. There weren’t any regions where everyone got vaccinated, so it’s not applicable to the real world.



  • Depending on the country, it’s pretty common for most milk production to be cows kept in extremely cramped conditions indoors with little to no space to move and fed processed grain instead of grass. It does make the milk taste worse, but it can be so much cheaper that customers don’t splurge on the more expensive milk, so don’t know what they’re missing. Even if you only ever see cows outdoors, you might also see low-welfare dairies and just assume they’re warehouses or factories and aren’t full of livestock, as a factory farm can look just like any other large industrial building.


  • Lots of people new to Linux get recommended Debian-derived distros, and so end up with distro packages that are a long way from bleeding edge. If they’ve just come from Windows, they’d have been using the latest release of everything they use, as most software projects don’t even announce a release until their Windows binaries are ready, and many auto-update. That means that a lot of people have being presented with versions of things they stopped using two to four years ago as their first Linux experience, and obviously they don’t see that as good enough. Most people don’t want to run versions of things that old, especially now there’s so much stuff to package that downstream packagers can’t feasibly backport every bug fix to older versions of every piece of software, so running an old version gets you old bugs rather than a balance of avoiding new bugs at the expense of new features.


  • Anything that’s not a true x isn’t x at all, it just resembles it. That’s why the ‘no true Scotsman’ fallacy is a fallacy. For example, ‘bugs’ that aren’t ‘true bugs’ aren’t bugs at all, they just look enough like bugs that laypeople would call them bugs despite being a different kind of insect (or if the layperson is being especially flexible with what they’re calling a bug, potentially not even an insect). Saying glass isn’t a ‘true solid’ is literally the same as saying it’s not a solid, but with the added implication that lots of people get it wrong. There’s also a common myth that glass is really a slow-moving liquid. You said something that is literally the exact opposite of the truth in a thread about scientific facts that sound up but are 100% real, and landed on something that gets commonly repeated as a surprising fact, so of course people are going to correct you.





  • Chemically, Sodium and Lithium are very similar, so any improvement that applies to one should be pretty applicable to the other. That’s actually one of the main strengths of Sodium batteries - most of the research that’s already gone into making Lithium batteries can be reapplied with minor tweaks. However, Sodium is inherently larger and heavier than Lithium, with fewer atoms fitting into the same space and those atoms weighing more. If research for Sodium batteries catches up with Lithium ones, they’ll still be worse just because of that, and at that point, research would get easier gains from improving Lithium batteries than Sodium ones.
