        The logic that nobody would ever die as long as nobody ever pulls falls through when you realize after 33 cycles you’re risking the entire human population on the whims of a stranger and that irrational actors will always exist.

        It becomes not if but when.

          Youre right but for the wrong reason. Id pull it thinking it was going one way and it would go the other.

        Cure for what? That’s a fascist argument. I am not accusing you. Just wanted to inform. I was intellectualizing like that once: if all humans die, life on the planet would thrive, species that go extinct wouldn’t be an issue we would only be seeing it as a product of the evolution of more biodiversity for sure…

        Yet… A friend pointed out, that such disease is just a theorization and reality has shown that this kind of scenarios are lived in, for example, catastrophes. In those cases, the world ending event hits harder to the most vulnerable. Typically, the poorest fraction. Billionaire and other rich people will have resources, bunkers, time, and so on… They may even be saved.

        And this is actually their agenda in, for example, climate change denialism and inaction.

        That’s one reason why elites don’t care about the ecocide.

          If the only people left alive were the cruelest, would they thrive? I know it seems unjust but we dont get upset that the dinosaurs once ruled the planet.

          Personally, I think peoplle are corruptable. People arent inherently anything but circumstance plays a much bigger role. Essentially the most vulnerable people are just unlucky. Given the right luck they could only mirror the elite, not change their structure.

          For the elite to see through the eyes of the homeless they would need to be made homeless and there is no other way.

            Saying that people are corruptible doesn’t imply they are corrupt. Thankfully we live finite lives and plenty of us can make it to the end before we corrupt ourselves.

            Given the right luck they could only mirror the elite, not change their structure.

            This is quite literally pretending the Age of Enlightenment never existed. We can change structures and have throughout history.

    232 is roughly four billion. We’ll need one or two more doublings to get every last person alive on the tracks.

    This introduces a new wrinkle in the experiment: all the switch operators are also tied to the track. Somewhere.

      But I don’t know if I trust literally infinite people. It might be better to kill one. Because unless you believe all humans are 100% willing to never kill someone then you’re risking a number of deaths larger than 1. (Potentially much larger.)

        No need to trust infinite people. You just need to get past 33 forks before you run out of people to operate the switch or to be tied to the tracks.

          It’s a thought experiment though, in the magical world where we could have all of humanity tied to rail road tracks by an omnipotent being, I don’t assume there to be a finite number of people.

          Would they not simply be trapped tied to the tracks until a nonexistent remaining person makes a choice? Also you’re trusting that 32nd person not to kill just under 5 billion people.

      Yes. But it keeps going forever, and eventually some chaotic-evil person will kill choose to kill 2^43 people, which is a thousand times the world’s population.

      That’s kind of how it feels like living in the modern age to be honest. We’re just doubling it until somebody decides to pull the lever.

    I’d get it done and over with. I would resent myself forever, and accept any punishment for it, but it’s better than waiting to see if someone wants to decide to kill off half the world later on. Would be even easier if I could take the first persons spot on the tracks so there only has to be one messed up person rather than two.

    I think you should pull the lever, even if this ended after the entire human population was on the track and the experiment doesn’t go on infinitely. Hear me out:

    When a person pulls the lever with a chance of 50% and in one case they kill 2 people and in the other case 0, the kind of average outcome is 0.5 * 2 + (1 - 0.5) * 0 = 1. Now let’s consider the last person in the chain of decision-makers. They would have 2^33 people on the tracks, or about the entire human population. To make the expected outcome be exactly one person, they’d have to pull the lever with likelihood x so that x * 2^33 + (1 - x) * 0 = 1 which would lead to x = 1/2^33 or about x≈0.0000000001. So only if the last person directs the train towards the people with less than this tiny chance, the expected outcome is smaller than 1. This chance is incredibly small, and far far smaller than I’d guess the actual percentage is. Think of the percentage of people that are psychopaths, or mass murderers, or maybe even just clumsy. If you evaluate the percentage as someone flipping that switch as anything above 1/2^33, you should therefore flip the switch yourself. You can guarantee that the outcome is ‘only’ one death, whereas the average outcome of just the last person likely exceeds 1 by a huge amount.

    I really wanted to calculate the percentage so that the expected outcome is 1 even if every person in the chain flips the switch with that chance, but wolfram alphas character limit let me down :(

      I am not seeing it. Are you saying the last person chooses between killing nobody and killing the entire population? Also, what about the intermediary likelihoods of pulling the lever?

        That was my assumption, yes. Because the last person would have the entire population on the tracks, and you can’t really continue after that.

        I neglected the intermediary likelihoods, because that calculation was too long for wolfram alpha, but I have since managed to get it working, and the conclusion is not significantly different. The expected number of deaths skyrockets, even if the chance of pulling the lever is tiny for every person.

          Got it! So you’re saying that the last choice is between 233 or 0 and the last guy has a probably x of pulling the lever and killing everyone (therefore a (1-x) probability of killing nobody).

          So, even if it’s guaranteed that nobody along the way pulls the lever (the best case scenario if we want 0 dead), the expected value at the last branch is x · 233 + (1-x) · 0. And the only way this is less than 1 is if x < 1 / 233, which is an absurdly tiny probability.

          If we also consider the intermediary probabilities, this already tiny probability threshold of 1 / 233 of killing nobody gets SMALLER because we’re allowing more chances for killing way more than 1 person along the way.

            That’s exactly right, you got it!

            The intermediary probabilities make it even worse, yes! But the overall probability is already ridiculously tiny, so I don’t think it changes the conclusion by a lot.

        They choose between half the whole population and the whole population (very roughly as it aligns alongside exponents of 2)

          That’s what the meme is. But the user’s calculation multiplies 1-x by 0, not 1-x by half the population. Or by the future expected value.

      Reading this analysis, I think it’s all but guaranteed that the person at the switch on the last step is Davros.
