Welcome to climate policy.
That implies that if nobody tries to stop climate change, it’ll never destroy the world.
You would need a crazy low probability of a lunatic or a mass murderer being down the line to justify not to kill one person
Edit: Sum(2^n (1-p)^(n-1) p) ~ Sum(2^n p) for p small. So you’d need a p= (2×2^32 -2) ~ 1/(8 billion) chance of catching a psycho for expected values to be equal. I.e. there is only a single person tops who would decide to kill all on earth.
You don’t even need a lunatic or mass murderer. As you say, the logical choice is to kill one person. For the next person, the logical choice is to kill two people, and so on.
It does create the funny paradox where, up to a certain point, a rational utilitarian would choose to kill and a rational mass murderer trying to maximise deaths would choose to double it.
It’s always “double it” Anyone after 34 flips the kill all humans, that’s their fault not yours
Why do you care whose fault it is? You’d want to minimise human deaths, not win a blame game.
Doubling action forever minimizes human deaths.
Unless someone decide to hit kill. In that case, it’s them doing it. I’m invalidating the argument that pre-empting imaginary future mass murders justifies killing one person today.
Idk which moral system you operate under, but I’m concerned with minimising human suffering. That implies hitting kill because chances of a mass murderer are too high not to. You also don’t follow traffic laws to a t, but exercise caution because you don’t really care whose fault it ends up being, you want to avoid bad outcomes (in this case the extinction of humankind).
Lever half way and it crashes.
Attempting to subvert the thought experiment only makes things worse. The trolley is full of child prodigies, all future geniuses that will cure cancer and solve the world’s problems. By sticking the lever halfway you kill all of them. The only way to save the child prodigies is to choose, left or right.
You couldn’t even bother putting in adult scientists that have already helped the world. It’s a hypothetical scenario, you know, you can put in anyone you want. So I’m putting the child prodigies to a test by having the save themselves from the half-lever. Should be relatively easy for them.
Might hit the 2nd guy with a lever and the peeps behind him depending on speed.
It might. Still better odds.
Thats actually a really good dilemma if you think about it. Like if everyone doubles it you basically don’t kill anyone. But you’ll always risk that there’s some psycho who likes killing and then you will have killed more. And if these choices continue endlessly you will eventually find someone like this. So killing immediately should be the right thing to do.
This is really the only answer. The only thing that makes it “hard” is having to face the brutality of moral calculus
Now, what if you’re not the first person on the chain? What if you’re the second one. Or the n one? What now? Would you kill two or n knowing that the person before you spared them?
The thing to do is kill now even if it’s thousands. Because it’s only going to get worse.
The best time to kill was the first trolly. The second best time to kill is now.
Yes, but it also kinda depends on what happens at and after junction 34, from which point on more than the entire population of earth is at stake.
If anything, this shows how ludicrously fast exponentials grow. At the start of the line it seems like there will be so many decisions to be made down the line, so there must be a psycho in there somewhere, right? But (assuming the game just ends after junction 34) you’re actually just one of 34 people, and the chance of getting a psycho are virtually 0.
Very interesting one!
It’s not that interesting. If you rephrase the question as a choice between a good option and a less good one, it’s still barely even a choice.
“Would you rather have only one (or, say, trillions) die now, or would you like to allow *at a minimum *twice that many people die the second we talk to a sadist?”
If you can’t choose the smaller number, all it means is that you lack moral strength - or the test proctor has put someone you know on the tracks, which is cheating. A highly principled person might struggle if choosing between their daughter and one other person. If it’s my kid versus a billion? That’s not a choice, that’s just needless torture. Any good person would sacrifice their kid to save a billion lives. I take that as an axiom, because anything else is patently insane.
Kill fewer people now is obviously the right answer, and not very interesting.
What is interesting is that the game breaks already at junction 34, which is unexpectedly low.
So a more interesting dilemma would have been “would you kill n people now or double it and pass it on, knowing the next person faces the same dilemma, but once all humanity is at stake and the lever is not pulled, the game ends.”. Because that would involve first of all figuring out that the game actually only involves 34 decisions, and then the dilemma becomes “do I trust the next 33-n people not to be psychos, or do I limit the damage now?”. Even more interestingly “limiting the damage now” makes you the “psycho” in that sense…
Double it. Then the other guy will double it, and so on. Infinite loop = no deaths.
And then there’s some psycho on round 34 who kills all 8 billion people alive on earth.
Can I move the rails to kill them all and then circle around and hit me?
