Vague idea for how to theoretically decide whether a mind's existence at any given moment is net positive, from a utilitarian standpoint:
I feel like some version of this has to logically follow if you assume that the utility of multiple experiences at once is equal to the sum of the utilities of the individual experiences (might not be true), plus some uncontroversial utilitarian assumptions, but I can't formalize the proof in my head.
If anyone has links to other attempts to get a utilitarian threshold for net positive/negative existence, they would be appreciated.
(I should note that I know approximately zero neuroscience, and don't know if the concept of an "individual experience" as distinct from other "individual experiences" happening in the same mind at the same time is coherent)
I like the exploration of ideas like this - thanks for that. I think this approach has some serious problems, though (note: all utilitarian calculations have serious problems - that criticism may be more general than helpful).
It's likely that some experiences are non-linear in utility per intensity.
I imagined something like having fun with my friends, or watching a funny movie, while feeling a mild pain in some part of my body. As long as I can mostly ignore it, the experience is pleasant on average. Now multiply everything by 10, and I will not be able to enjoy the fun, because I will focus on the pain.
Yeah, the proposal is to multiply the experience, not the inputs. It's just sometimes difficult to imagine.
Responding to 3):
What is your standing to judge your imagined version of someone's experience? Maybe your preferences are different enough from the subject's that you're simply wrong in your comparison.
You're right and I should have said "imagine the point at which they are indifferent", "would they prefer the 10x experience or the 1x experience", etc. Imagining whether I would prefer it could be a decent approximation of their preferences, though.
Responding to 2):
It's likely that some experiences are non-linear in utility per intensity.
In the post, I defined intensity as linearly proportional to utility. If you think wording it as "intensity" is misleading because what we generally think of as "experience intensity" isn't linearly proportional to utility, then I agree, but can't think of a better term to use.
Or that you'd have to crank up some parts of the experience and not others. For instance, enjoying the contrast of bitter and fruity in a shot of espresso - there's no way to scale the whole thing up 10x, you have to pick and choose what to intensify, and then your result is subject to those modeling choices.
If I'm understanding you correctly, you're saying that the experience of enjoying the contrast of bitter and fruity can be modeled as the individual experiences "bitter 1, bitter 2, bitter 3, ... ,fruity 1, fruity 2, fruity 3, ..." and the total utility of the 10x scaled experience depends on which ones you group together when summing the utilities. For example, if your "utility groups" are bitter 1 + fruity 1, bitter 2 + fruity 2, etc., it comes out with higher utility than if you group them as bitter 1 +bitter 2 + etc and fruity 1 + fruity 2 + etc, because the specific combination of bitter and fruity is what makes it a good experience.
I disagree that the individual experiences are bitter 1, bitter 2, ..., fruity 1, fruity 2, ... ; I feel like it should be more like bitter-fruity 1, bitter-fruity 2, ..., bitter 1, bitter 2, ..., fruity 1, fruity 2, ... The combination of bitter and fruity ("bitter-fruity") is a distinct individual experience in the set of experiences occurring at that moment, and in that set might also be included individual "bitter" and "fruity" experiences. Here, we can just intensify each individual experience by 10 (i.e. multiply the utility of the experience by 10 while keeping it as the same "type" of experience) and sum their utilities.
Also, why 10x rather than 0.1x, or 0x (direct comparison of experienced to not-experienced).
I don't really know what it would mean to prefer to "not experience" something. You're always experiencing something; your baseline mental state is an experience. If your baseline mental state has exactly 0 utility, this would work, but your baseline mental state isn't necessarily exactly 0 utility. If "not experiencing" something means shaving that much time off the rest of your life, this still feels like a conceptually weaker version of a "preference". When comparing two experiences, I can imagine being on experience 1, then deciding I want to switch to experience 2, then actually deciding experience 1 is better, etc., until some sort of equilibrium is reached and I make up my mind. (Keep in mind that how tired you are of the experience is itself part of the experience, and held constant, so you wouldn't keep jumping back and forth endlessly.) Theoretically, the analogous way to compare an experience with the absence of experience would be jumping between [your entire mind being turned off except for the part that allows you to think and make decisions] and the experience, but that's a harder thought experiment to have than imagining jumping between two different experiences.
I hadn't thought of comparing 1x to 0.1x; that's a good idea, and I don't object to it. I imagine 1x to 0.1x is more useful if each individual experience has a lot of utility (or disutility), and 1x to 10x is more useful if each individual experience only has a little utility (or disutility).
(I will respond to 3) and 4) tomorrow, it's getting late and I should sleep)
First, I want to make sure we're separating the validity of the model itself from concerns with applying it. I'll try to be clear about which one I'm talking about for each part.
I'll respond to each number in a separate reply because the format of the conversation will be a mess otherwise. Starting with 1):
Where do you get this list?
Could you be more specific? Is this question centered around how I know what other people are thinking, or how to separate a whole experience into individual experiences ?
And how do you account for future unexpected experiences?
I don't know how to respond to this. What part of the model depends on accounting for unexpected future experiences? If you're asking generally how I would predict future experiences, I don't have a good answer, but this seems both separate from the philosophical model itself and not an objection to the application of this specific philosophical model (it applies to all experience-based consequentialism).
Intentionally rationalizing against your beliefs could be a good strategy for doing a cost-benefit analysis. For example, if you currently support increasing the minimum wage, imagine yourself as someone who is against it, and from that perspective come up with as many disadvantages to it as possible. I'm sure I'm not the first to come up with this idea but I haven't seen it anywhere else; is there a name for this concept?
Speculative Model For How Moral Arguments Work
Credibility warning: All of this is wild post-hoc speculation based on my vague intuitions. Don't read it as if it has any semblance of authority. Feel free to bring up actual evidence if it confirms or denies my speculations, though. Also, this is my first post on LW so please point out if I violated any conventions, norms, etc.
Readability warning: This post was not very carefully edited, so the clarity, grammar, formatting, etc. might be a disaster, and there's a good chance it's nearly unreadable at times. Feel free to ask for clarification.
Word abuse warning: I might have unintentionally equivocated the meaning of "moral" between "not immoral" and "actively good" at some point. I think I consistently used it as "not immoral", but let me know if I equivocated and I'll fix it. I also might have unintentionally equivocated "immoral" between "bad but can be balanced out by good things" and "so bad that it can never be balanced out by any amount of good things". Oh, I also might have used the word "axiom" in a slightly unintuitive way. Oops.
_________________________________________________________
Note: When I refer to morality in this post, I do so in the sense of "these are our most fundamental goals/things we should avoid" or "this is the fundamental goodness/badness of these actions", not "we should act like these are our goals in order to achieve the real fundamental goals".
Morality is fundamentally subjective and feelings-based but there seem to be ways that I can be persuaded of fundamental moral claims that isn't just showing me pictures of starving African children. I'm currently a utilitarian, and there was some way I was talked into it, and I can articulate the thoughts and arguments that led me here, but I can't describe exactly why or how they led me here. This a half-attempt at answering that question by discovering the underlying process that makes me convinced by some moral arguments and unconvinced by others.
I think of moral frameworks as sets of axioms about what is "moral" or "immoral" that follow deductive logic. There are a few ways I think I can be convinced or unconvinced of a moral axiom:
Footnotes:
[1]: For what it's worth, I do consider this one to be "disproven" in the sense that I'm no longer convinced it's immoral, because I feel more strongly about increasing utility in all cases than I do about not killing people for their organs, which falls under the process I mentioned for resolving contradictory axioms, I think?
[2]: Now that I think about it, this is probably a horrible example because our intuitions on flooding the city are probably based on actual features about the city like buildings and culture and whatnot, so it's kinda cheating to say "hold everything between the ocean and city constant and ignore all that". But what makes this feel like valid reasoning for why this is a horrible example? I should have to justify that since it's kind of what this post is about. Hmm.
[3] Phrased as "you" because I have mixed feelings about whether killing a human (i.e. causing net human death) is necessarily bad in the first place and didn't want to mislead about my actual beliefs, but I assume most people here feel that killing a human is necessarily bad unless it's balanced out by a positive.
[4] "A-like" here meaning that it's analogous to A and carries the same "emotional reaction number" as A
[5] Uhh, maybe there's some way to say they're the same degree of infinity and it somehow cancels? Probably not.
