This matches my memory as well.
I have no idea, but I wouldn't be at all surprised if it's a mainstream position.
My thinking is that long-term memory requires long-term preservation of information, and evolution "prefers" to repurpose things rather than starting from scratch. And what do you know, there's this robust and effective infrastructure for storing and replicating information just sitting there in the middle of each neuron!
The main problem is writing new information. But apparently, there's a protein evolved from a retrotransposon (those things which viruses use to insert their own RNA into their host's DNA) which is important to long term memory!
And I've since learned of an experiment with snails which also suggests this possibility. Based on that article, it looks like this is maybe a relatively new line of thinking.
It's good news for cryonics if this is the primary way long term memories are stored, since we "freeze" sperm and eggs all the time, and they still work.
Do you know if fluid preservation preserves the DNA of individual neurons?
(DNA is on my shortlist of candidates for where long-term memories are stored)
Consider finding a way to integrate Patreon or similar services into the LW UI then. That would go a long way towards making it feel like a more socially acceptable thing to do, I think.
1Yeah, that's not what I'm suggesting. I think the thing I want to encourage is basically just to be more reflective on the margin of disgust-based reactions (when it concerns other people). I agree it would be bad to throw it out unilaterally, and probably not a good idea for most people to silence or ignore it. At the same time, I think it's good to treat appeals to disgust with suspicion in moral debates (which was the main point I was trying to make) (especially since disgust in particular seems to be a more "contagious" emotion for reasons that make sense in the context of infectious diseases but usually not beyond that, making appeals to it more "dark arts-y").
As far as the more object-level debate on whether disgust is important for things like epistemic hygiene, I expect it to be somewhere where people will vary, so I think we probably agree here too.
1I meant wrong in the sense of universal human morality (to the extent that's a coherent thing). But yes, on an individual level your values are just your values.
I see that stuff as at best an unfortunate crutch for living in a harsher world, and which otherwise is a blemish on morality. I agree that it is a major part of what many people consider to be morality, but I think people who still think it's important are just straightforwardly wrong.
I don't think disgust is important for logic / reflectivity. Personally, it feels like it's more of a "unsatisfactory" feeling. A bowl with a large crack, and a bowl with mold in it are both unsatisfactory in this sense, but only the latter is disgusting. Additionally, it seems like people who are good at logic/math/precise thinking seem to care less about disgust (as morality), and highly reflective people seem to care even less about it.
ETA: Which isn't to say I'd be surprised if some people do use their disgust instinct for logical/reflective reasoning. I just think that if we lived in the world where that main thing going on, people good at that kind of stuff would tend to be more bigoted (in a reflectively endorsed way) and religious fundamentalism would not be as strong of an attractor as it apparently is.
That doesn't seem right to me. My thinking is that disgust comes from the need to avoid things which cause and spread illness. On the other hand, things I consider more central to morality seem to have evolved for different needs [these are just off-the-cuff speculations for the origins]:
- Love - seems to be generalized from parental nurturing instincts, which address the need to ensure your offspring thrive
- Friendliness - seems to have stemmed from the basic fact that cooperation is beneficial
- Empathy - seems to be a side-effect of the way our brains model conspecifics (the easiest way to model someone else is to emulate them with your own brain, which happens to make you feel things)
These all seem to be part of a Cooperation attractor which is where the pressure to generalize/keep these instincts comes from. I think of the Logic/reflectivity stuff as noticing this and developing it further.
Disgust seems unsavory to me because it dampens each of the above feelings (including making the logic/reflectivity stuff more difficult). That's not to say I think it's completely absent form human morality, it just doesn't seem like it's where it comes from.
(As far as Enforcement goes, it seems like Anger and Fear are much more important than Disgust.)
This is fascinating and I would love to hear about anything else you know of a similar flavor.
Caloric Vestibular Stimulation seems to be of a similar flavor, in case you haven't heard of it.
