Also, compliments from a low SMV Guy are deemed to be insincere, because they are assumed to be seeking something in return. Compliments from a high SMV guy, who is implicitly drowning in pussy, are more likely to be sincere and he is less likely, in their minds, to be fishing for something more.

Yeah, already explained that to some girl at PPD who wondered how TRP explains how her "beta friend" (beta as in: supper-compliant, nice, acommodating etc.) happened to get laid all the time. Oh, he also was super-gorgeous.

My answer:

So do you have some sort of beta allowance scale? Like if you're this sexy, then you can be this beta if you want to get laid?

Pretty much. My take on it:

If you're already "high value" (whether the value is power, wealth, looks, status, genuine charme or any mix thereof), people assume that you're used to be treated as if the sun shines out of your ass - if you're kind, nice, acommodating and forthcoming from that position, it may actually count in your favor (unless people get used to that kind of special treatment) because it implies that despite you having been dealt a winning hand (and therefore being well able to get away with being an asshole without having to fear serious repercussions), you'll still go out of your way to show that you value other people. Basically, by being special, some of that specialness (subjectively) rubs off on them. Read Primary Colors and the descripion of how Bill Clinton Jack Stanton is described as awesome at pretending to be genuinely interested in the people he has around him and how that is responsible for his leadership charisma.

This by the way is also the problem when women say how much they'd appreciate being treated like a princess: they don't imagine Joe Everyman doing that but Brad Pitt, i.e. a guy that checks all their other boxes and finally is nice and forthcoming as a cherry on top. However, they usually omit that part (which is also the reason why TRPs take on women's advice is "pay attention to what they do, not what they say").

Now imagine the opposite - a low value person (whether it's being low status, weak, unattractive, introvert or any mix thereof) who is your stereotypically "nice guy": when dealing with that kind of people, the average person knows (a) that they could at the very least inconvience them without too many problems if they wanted to (think of your average pupil joining the picking on the unpopular guy/girl, or your average citizen being considered trustworthy over a homeless guy by default) and (b) that these people may probably hope to gain something by being nice, and, more importantly, gain more out of any relationship they establish that way than the other, "higher value" person (whether or not that's true doesn't matter, it's the perception that counts). In that situation, niceness isn't seen as something special, but as something one easily takes for granted in the best case and groveling with ulterior motives in the worst case; and it may also exacerbate the perception of being of higher value than the nice person ("well, if he is that forthcoming, he is probably more desperate than I thought").

Ironically, being effective at being aggressive or an asshole may (not necessarily has to) counter the effect of being low status because on the one hand it takes the person being treated in such a manner down a notch, and on the other (if played right) it projects a devil-may-care attitude and can come over as genuine confidence even when there's nothing to back it up. There's a reason some dark triad people can get away with so much stuff even if they're, realistically seen, for all intents and purposes absolute lowlifes.
