  • Let me try to explain it another way.

    We know that 1/3 of the dead are children, according to the headline. We also know that children make up about half the population of Gaza. We assume that none of the combatants are children.

    If a person is killed, that person is either an adult combatant, an adult civilian, or a child civilian. Since child civilians make up 1/3 of the dead and there are as many adult civilians as child civilians in Gaza, adult civilians therefore make up another 1/3 of the dead. That adds up to 2/3 of the dead being civilians. 2/3 civilian dead and 1/3 combatant dead is a 2:1 ratio of civilians to combatants killed.


  • That’s not what I’m saying - I don’t have a term that represents “#deadKids/#allCivilians”.

    If I were to use your notation, I would write:

    #deadKids/#allDead = #deadCivilians/#allDead * #allKids/#allCivilians

    I recognize that it’s macabre to treat this as a word problem, but the math works out if you do. If out of 100 dead people, 33 are combatants and 67 are civilians (the 2:1 civilian to combatant ratio I have calculated) and half of the dead civilians are children, then there are 33 dead children, which is the “one third” in the headline.



  • If we assume that (1) the civilian population is 50% children and (2) none of the combatants are children then:

    (fraction of the dead that is children) = (fraction of the dead that is civilians) * (fraction of the civilians that is children)

    (1/3) = (fraction of the dead that is civilians) * (1/2)

    (fraction of the dead that is civilians) = (1/3) ÷ (1/2) = (2/3)

    This is where my 2:1 civilians to combatants number comes from.

    The fact that among the dead, the ratio of civilians to combatants equals the ratio of adults to children is a coincidence.


  • Many people seem to think so but the evidence doesn’t support their argument. A 2:1 ratio of civilians to combatants killed isn’t particularly low but it is far closer to the best that Western armies have been able to accomplish than it is to the ratio seen from armies that are not trying to reduce civilian casualties. For example, Russia’s ratio in Mariupol is approximately 8:1 and that was against Ukrainian soldiers in uniform who weren’t deliberately hiding among civilians. Urban warfare always involves heavy civilian casualties.

    My worst review said that my paper was technically sound but my entire specialty was a “cottage industry” generating computational models with no real-world relevance and therefore the paper should be rejected. The editor offered the opportunity to rebut but what could I say to something like that?

    (The reviewer still lives, as far as I know.)

    On the plus side, this meant that I was rejected by PNAS but then published in BJ.

    Species with internal fertilization tend to have females care for the young because the male is the one who can leave first. He can maximize his reproductive success by searching for other females while the female is left with the choice between putting a lot more time and energy into caring for the offspring or leaving them to die.

    Species with external fertilization usually have the opposite dynamic. The female lays unfertilized eggs and then leaves. The male is the one stuck caring for them because they would die otherwise. However, the males of some species have evolved to be too clever for this:

    Among the maternal mouthbrooding cichlids, it is quite common … for the male to fertilise the eggs only once they are in the female’s mouth.








  • I don’t have anything to suggest on Lemmy. There’s so little activity that I participate in every community where I see an interesting post, except for those communities which are specifically for people with some particular set of beliefs which I don’t share.

    If you’re looking beyond Lemmy, there are are the comment sections of the SlateStarCodex/AstralCodexTen blog and the blogs it links to as well as some associated forums and subreddits. You’ll find plenty of liberal libertarians and the comments tend to be polite and high-effort, but keep in mind that a dedication to free speech means that people with opinions that can’t be discussed elsewhere participate too. It’s a bit much for me sometimes.


  • I acknowledge that almost all people (including me) couldn’t survive on their own. Even those that could survive (let’s say that their bunkers have robust long-term life-support systems) still couldn’t live completely alone for many years without going crazy.

    I don’t reject relationships with other people, but I think they should be between independent individuals who associate with each other only because they both want to. (Violating this principle is sometimes necessary but always undesirable.) You appear to think otherwise, and I suppose that’s a fundamental value difference that can’t be resolved through debate. I do want to point out that if I were in charge, my rules wouldn’t prevent you from voluntarily living life your way. I suspect that your rules wouldn’t leave me the analogous option.

    Edit: I suppose that I do feel like I have some obligations to my family members despite being related to them through no choice of my own. Is that how collectivists feel (to a lesser extent) about everyone else?


  • The preppers are different because they want to be left completely alone. They don’t see any acceptable role for government in their lives. I don’t think they’re being realistic. Freedom isn’t free, as the saying goes.

    The techno-libertarians are much more engaged with society and do see a role for government, even if that role is small and (at least according to some of them) bizarre by conventional standards. I’m not going to deny that the bunker-building types are involved in the movement. I often don’t agree with the weirder people involved, but I like that techno-libertarians are willing to hear people out and judge their ideas rationally rather than shunning them for being weird.

    (I think I might have a bunker built if I was rich enough. The expected utility of it is higher than that of, say, a second yacht. Human guards are a dead end. Probably the best thing that can be done if civilization totally collapses and you manage to get inside is blowing up the entrance so that anyone who wants to get to you has to move a thousand tons of rock first. You probably won’t ever get to leave, but it’s better than what would happen if you did.)
