The problem with talking about things is that we don’t really have a good shared ontology of how “preferences”/”desires”/”values”/etc work, and they don’t work the way people think they do.
Basically everything is way more context dependent than anyone realizes—as in, “I only wanted to go to the store because I thought it had the food I wanted”, to give a trivial example. But that food you had a preference for is subject to change as your bodies needs for nutrients changes. Even things like people’s identities as “asexual” or “straight” are prone to update with the evidence we come across.
So then you try to say “Well, that’s ‘tastes’, when I talk about ‘values’ I mean things like ‘autonomy’”. Except that kind of thing is merely instrumental as well—stabilized by motivated blind spots about how useless autonomy can be in the right contexts. And then the right contexts come along, and your “values” shift. Which can sound like “Oh no! Value drift!” from the outside, but once you get there, it’s just “Oh no, that store was closed. It’s my recognition of that which has changed”.
Then you try to retreat to “Okay, but pain is bad. Like, by definition!”. Except it isn’t, because masochists. Which aren’t even uncommon, with how many people like spicy food, and hard massages that “hurt in a good way”.
The last step seems to be avoidance of suffering, saying “Ah, right, pain isn’t suffering” but suffering is the definition of bad!. Except we choose that too! Suffering is what we choose in order to stave off the loss of hope. Often without realizing it, so we can get stuck with unproductive suffering which really is good to eliminate, but it’s something we choose nonetheless. And becoming conscious of it can allow more deliberate choice between hopelessness and continued suffering.
The whole thing is hard to make sense of, so it’s kinda “Of course people are going to use terms in unclear and conflicting ways”. When you say people should talk about things like “Their own preferences”, are you referring to their preference to go to the store, or to eat the food that they believe the store has for them? Or something upstream of that? When you talk about “normative values”, what the heck is that, exactly? If it’s “The thing that we should value”, then what exactly is that ‘should’ being used to distract from? Do we have any shared and accurate idea of what this means, descriptively speaking?
I think we need more deliberate study of how human tastes/desires/wants/values/etc change or don’t, before we’re going to have smooth hiccup-free communication on the topic. I agree with you that these terms conflate things, but I don’t think we have the option of not conflating things yet. So I’m nudging away from “Just use clear language and then everything will be clear” and towards “notice what your concepts might be hiding, and how much ambiguity is necessarily left”.
I like this post because it takes things you can only learn by “actually doing things”, and then presents them in ways that can be generalized.
This part in particular, because the default assumption is “Oh no, can’t cross the limit!”, yet this is true about a lot of things.
Also, even if you’re just driving to visit your grandma and not pushing the limits of traction, a traction aware driver will drive differently than your average driver. For example, it’s quite common to approach a red light at their current driving speed, only to start braking harder and harder at the end. Which is a foolish use of the safety margin, and also slower than the person who brakes gently and early, and therefore is more likely to still have momentum when the light turns green.
