I'd like to think that this accusation also carries a hint that this is quite an extraordinary claim, and therefore requires extraordinary evidence.

The hint was overwhelmingly clear. You were saying that your opponent was the one that needed lots of evidence while trying to present your own position as the default.

With respect to this particular premise your claim of 'extraordinary' struck me as incredibly naive. That social behaviours reduce to fitness maximising strategies is trivially obvious (and not all that interesting). There are of course going to be exceptions to the rule, humans being far from completely optimised but this claim:

the assumption that all social activity reduces to fitness strategies is in sharp contrast with reality and lacks evidence

... combined with things like:

the problem remains that apart from some anecdotal evidence, nobody has a clue as to whether PUA works

... suggests to me that the 'reality' you are appealing to is a purely social reality, not one that is determined by interaction with the world. "Nobody has a clue as to whether PUA works"? What the...? Anyone who has lived among humans with a modicum of introspection would have more than a 'clue' that it would work. "Bloody obvious social skills development combined with lots of practice and trial and error' doesn't stop being effective just because it gets a TLA applied.

I'm frankly amazed that your refutation wasn't downvoted to oblivion. It completely misuses the fallacy of 'affirming the consequent' and implies a lack of understanding of how Bayesian reasoning works.

Note that I don't even agree with shockwave's claim as he specifies it. Your reply is just completely confused and made all the worse by opening with 'This is a terrible argument'. When you lead with that sort of denunciation (and presumption) the bar gets raised and you really need to follow up with particularly solid reasoning.

No, I didn't offer any position on how much of human social behavior is fitness strategy and thus didn't present anything as the default. I pointed out, correctly, that the claim that all social acts are fitness strategies is an extraordinarily strong claim.

There are of course going to be exceptions to the rule

Since my opponent's argument explicitly deduced that PUA-denunciation is a fitness strategy directly from its being a social act, and nothing else, it brooks no exceptions to the rule. If the rule is not universal, the argument falls through.

"Nobody has a clue as to whether PUA works"? What the...?

It'd be interesting to see a reference to a study, a survey, anything other than anecdotal evidence. Something like this, for example.

"Bloody obvious social skills development combined with lots of practice and trial and error"

Oh, I see. Well, you're welcome to your definition of PUA, I'm not interested in debating it. If you have any data, do share.

Since my opponent's argument...

Be very wary when you start thinking of a participant in a conversation as an "opponent". Discussions are not battles, and the goal is not to win; it is to acquire correct beliefs. And/or to make yourself look good. But if you think of it as a battle, you are more likely to reject true some true statements that seem like evidence against your beliefs, and to accept false ones that seem like evidence for them. The consequences of that may be farther reaching than just the conversation they came up in.

I kind of picked up the term from the comment I was replying to; but you are right, I shouldn't have. Thanks.
