Track record: My own cynical take seems to be doing better with regards to not triggering people (though it's admittedly less visible).
Any suggestions for how I can better ask the question to get useful answers without apparently triggering so many people so much?
First off, I'm kind of confused about how you didn't see this coming. There seems to be a major "missing mood" going on in your posts on the topic – and I speak as someone who is sorta-aromantic, considers the upsides of any potential romantic relationship to have a fairly low upper bound for himself[1], and is very much willing to entertain the idea that a typical romantic relationship is a net-negative dumpster fire.
So, obvious-to-me advice: Keep a mental model of what topics are likely very sensitive and liable to trigger people, and put in tons of caveats and "yes, I know, this is very cynical, but it's my current understanding" and "I could totally be fundamentally mistaken here".
In particular, a generalization of an advice from here has been living in my head rent-free for years (edited/adapted):
Tips For Talking About Your Beliefs On Sensitive Topics
You want to make it clear that they're just your current beliefs about the objective reality, and you don't necessarily like that reality so they're not statements about how the world ought to be, and also they're not necessarily objectively correct and certainly aren't all-encompassing so you're not condemning people who have different beliefs or experiences. If you just say, "I don't understand why people do X," everyone will hear you as saying that everyone who does X is an untermensch who should be gutted and speared
because in high-simulacrum-level environments disagreeing with people is viewed as a hostile act attempting to lower competing coalitions' status, and failing to furiously oppose such acts will get you depowered and killed. So be sure to be extra careful by saying something like, "It is my current belief, and I mean with respect to my own beliefs about the objective reality, that a typical romantic relationship seems flawed in lots of ways, but I stress, and this is very important, that if you feel or believe differently, then that too is a valid and potentially more accurate set of beliefs, and we don't have to OH GOD NOT THE SPEARS ARRRGHHHH!"
More concretely, here's how I would have phrased your initial post:
Rewrite
Here's a place where my model of the typical traditional romantic relationships seems to be missing something. I'd be interested to hear people's takes on what it might be.
Disclaimer: I'm trying to understand the general/stereotypical case here, i. e., what often ends up happening in practice. I'm not claiming that this is how relationships ought to be like, nor that all existing relationships are like this. But on my model, most people are deeply flawed, they tend to form deeply flawed relationships, and I'd like to understand why these relationships still work out. Bottom line is, this is going to be a fairly cynical/pessimistic take (with the validity of its cynicism being something I'm willing to question).
Background claims:
Taking on purely utilitarian lens, for a relationship to persist, the benefits offered by it should outweigh its costs. However, on my current model, that shouldn't be the case for the average man. I expect the stated downsides to be quite costly, and if we remove consistent sex from the equation, the remaining value (again, for a stereotypical man) seems comparatively small.
So: Why do these relationships persist? Obviously the men might not have better relationship prospects, but they could just not have any relationship. The central question which my models don't have a compelling answer to is: what is making these relationships net positive value for the men, relative to not having a romantic relationship at all?
Some obvious candidate answers:
I'm interested in both actual data and anecdata. What am I missing here? What available evidence points strongly to some of these over others?
Obvious way to A/B test this would be to find some group of rationalist-y people who aren't reading LW/your shortform, post my version there, and see the reactions. Not sure what that place would be. (EA forum? r/rational's Friday Open Threads? r/slatestarcodex? Some Discord/Substack group?)
Adapting it for non-rationalist-y audiences (e. g., r/AskMen) would require more rewriting. Mainly, coating the utilitarian language in more, ahem, normie terms.
Given the choice between the best possible romantic relationship and $1m, I'd pick $1m. Absent munchkinry like "my ideal girlfriend is a genius alignment researcher on the level of von Neumann and Einstein".
