This seems to me like an attempt to run away from the premise of the thought experiment. I’m seeing lot’s of “maybes” and “mights” here, but we can just explain them away with more stipulations: You’ve only seen the outside of their ship, you’re both wearing spacesuits that you can’t see into, you’ve done studies and found that neuron count and moral reasoning skills are mostly uncorrelated, and that spacefilight can be done with more or less neurons, etc.
None of these avert the main problem: The reasoning really is symmetrical, so both perspectives should be valid. The EV of saving the alien is 2N, where N is the human number of neurons, and the EV of saving the human from the alien perspective is 2P, where P is the is alien number of neurons. There is no way to declare one perspective the winner over the other, without knowing both N and P. Remember in the original two envelopes problem, you knew both the units, and the numerical value in your own envelope: this was not enough to avert the paradox.
See, the thing that’s confusing me here is that there are many solutions to the two envelope problem, but none of them say “switching actually is good”. They are all about how to explain why the EV reasoning is wrong and switching is actually bad. So in any EV problem which can be reduced to the two envelope problem, you shouldn’t switch. I don’t think this is confined to alien vs human things either: perhaps any situation where you are unsure about a conversion ratio might run into two envelopy problems, but I’ll have to think about it.
See, the thing that’s confusing me here is that there are many solutions to the two envelope problem, but none of them say “switching actually is good”.
What I’ve been suggesting is that when looking inside the envelope, it might subsequently make sense to switch depending upon what you see: when assessing human/alien tradeoffs, it might make sense to prefer helping the aliens depending on what it is like to be human. (It follows that it could have turned out that it didn’t make sense to switch given certain human experiences—I take this to play out in the moral weights context with the assumption that given certain counterfactual qualities of human experience, we might have preferred different schemes relating the behavioral/neurological indicators to the levels of welfare.)
This is not at all a rare view among academic discussions, particularly given the assumption that your prior probabilities should not be equally distributed over an infinite number of possibilities about what each of your experiences will be like (which would be absurd in the human/alien case).
