It would be the right thing to do but I don't think I would be able to bring myself to do it

In the unlikely event you're ever faced with a "trolley problem" in real life, don't forget to discount the potential gains by the likelihood that your action will lead to the outcome.

@WilliamGunn “discount the potential gains by the likelihood that your action will lead to the outcome” could you elaborate what you mean by this with some examples? potential gains/p(your action will lead to the outcome)?

@cheshirecat It's no good to sacrifice yourself to save someone if someone else kills them right after you sacrifice yourself, right? I'm sure you can imagine various scenarios where people have various likelihoods of living and where your sacrifice is more or less effective at changing those probabilities.

@zyc Yeah, I knew what you meant, I just find that less interesting to think about than more realistic scenarios.

@WilliamGunn Would you have chosen yes if it is the less realistic scenario?
