Somewhere in the archive is an article by lukeprog where he decided to break up with his girlfriend and wanted to let her down easy. In deciding how to do that, he debated with himself about telling her that his desire for a woman with larger breasts was an evolution-caused preference, not a comment on the woman specifically.

That's nonsense, and uncritical acceptance of evo-psych runs the serious risk of exacerbating the problem.

The problem with LukeProg's decision to write that break up essay wasn't evo-psych. The problem was that writing a huge essay on why you're breaking up with someone, including detailed analysis of why there is insufficient attraction is a horrible thing to do to someone without even giving any benefit to yourself.

This doesn't constitute an argument here against evo-psych as an accurate description of reality. It does constitute:

  • A solid illustration of how social awkardness can result in doing harm to others despite all the best intentions.
  • An extremely weak appeal to consequences---an argument that evo-psych should not be studied because bad things could happen from people understanding evolutionary psychology. I describe it as weak since there is little indication that the insult Luke gave given his awareness of evo-psych is any worse than the insult he would have given if ignorant. For example "I'm dumping you because I like big tits, it's just the way I am" is about as insulting as "I'm dumping you because I like big tits, I just evolved that way" (details changed as necessary).

In conclusion, keep your moralizing out of my epistemic rationality! At least while posting on this site, please. You can argue that a particular subject should not be discussed here for instrumental reasons in accordance with your own preferences. However it is never appropriate (on lesswrong, I assert) to argue that a belief must be considered false because of perceived consequences of someone believing it.

I don't know that that's necessarily the case. My first serious girlfriend wrote me a very long e-mail before our break-up, laying out her rational analysis of why she believed our relationship was untenable in the long term; she actually succeeded in persuading me to see it her way, which I'd been resisting for emotional reasons. That allowed us to have an amicable parting of ways, and we remain good friends to this day.

That's amazing. Can we see a copy of the email?

I'll think about that -- from the upvotes, it appears you're not the only Less Wronger interested (at least, I assume an upvote to a one-liner request like that means "I'd like to see it, too"). I wouldn't post an unedited copy, as there are some details in it that I consider very private, as, I think, would my former girlfriend. But I'll take a look at it later and see what would need to be redacted. I would also have to ask her permission before posting any of it, of course, and I'm reluctant to bother her just now -- she has a newborn daughter (as in, born last week), so I expect she's rather preoccupied at the moment.

I'm guessing that this is more likely to work out when it's the female who decides to be rational about it.

I'm guessing it's more likely to work out when it's the partner of a LessWronger who initiates it, than when it's the partner of a nonLessWronger.

Why do you think so?

Why do you think a man would think so?

I don't know! That was why I asked.

Don't you? Fine, I'll bite. While the bell curve is pretty wide for both genders, an average (western?) male tends to be more analytical and reserved and less emotional than an average (western?) female. At least in my (admittedly limited) personal experience observing my family, friends and acquaintances. Certainly the cultural stereotypes bear it out, as well. Thus he would be (again, on average) more inclined to listen to reasoned arguments, as opposed to "It's not working out between us" with some made-up excuses designed to make him feel better. Whereas she (on average) would be likely to take every logical argument as in Luke's story, as a personal affront, insult and rejection. There are plenty of exceptions, but if you take 1000 break-ups, I'd wager that in the majority of the cases a bit of reason on the woman's side would make it less painful for the guy, while a bit of logic on the man's side would probably make it more painful for the girl than "it's not you it's me".

I have no idea how same-sex or other less-standard breakups work out in terms of rationality.

Your perception of the people you know plus cultural stereotypes is really pretty weak evidence. I could make the following argument: In my immediate family, the men are more emotional and less analytical/reserved than the women - they tend to get angry/aggressive in response to difficult things, whereas the women seem to stay calm. Plus, cultural stereotypes bear out the idea that men are more aggressive/angry than women. Therefore, men would be more likely to take this kind of letter badly.

I'm not making that argument, but I can't see that it would be much weaker than yours.
