To a point you're right, taking out the systems comes down on the side of people who prefer RP.
You're conflating "RP" with "social RP." The two are not interchangeable, even though you may think so.
Anyway, I don't mean to overly single you out for hostility other than to point out the at this point comical ludicrousness of people having this argument seriously the number of times they do. Sorry you got to the party late, but you really aren't adding anything.
Actually, writing poses after social rolls wasn't suggested in this thread at all, and everybody was speaking in terms of posing your attempt first and rolling to see if it works. In the context of this thread, that is new.
I agree that it's a tough thing to get into. But I just get the impression that there's also a psychology of "autonomy," where people are much more comfortable admitting that their character might not have a particular skillset or domain knowledge than they are admitting that their character quite legitimately can be deceived, manipulated, or intimidated. People tend to believe that they are "above the bullshit" and, by extension, so are their characters.
I think a great deal of why people are opposed to social dice mattering much is because it not only acknowledges, but rubs the player's face in, the reality that in some cases their characters are decidedly not above the bullshit, and are in fact subject to it like the rest of us.
@Lain I like this idea a lot but having a third party present for every social roll who knows enough about what's going on to make suggestions like that might be a bit harder than just having a third party who can spot and penalize absurd uses of the code. I have to yield to @Arkandel and @Thenomain when they say having a third party at all isn't feasible if social conflict is an every-day thing.
You'd only need a third party when someone tries to cop out of the roll outcomes or overplay their hand on them. "I get so intimidated it triggers my fight instinct" is one such example. You can even incentivize playing nice and not calling on the GM/Wiz/ST to babysit you by saying that if you get called out, and then the babysitter comes, and you're found to be in the wrong, then you lose XP or something. You get punished for wasting their time.
So this is a real issue with these skills - politics, lying, manipulating, etc - when the roleplay points in one direction and the skills in a different one. If a guy comes to my PC, makes a fucking dumb proposal while insulting my woman in the process and he's caught at a lie but has high social stats then apparently I'm supposed to ignore the roleplay and just go with the results of a roll? Yes. That's... basically what MU* systems say. If I don't then I'm not playing right.
This is actually why I brought up roll-first-pose-later earlier. I agree, expecting dumb poses to yield positive results is dumb. But if you lose the roll, and the player is a bit awkward, the player can ask you, OOC, "So what kind of thing would persuade your character to do X for him?" You answer OOC, he writes a pose to that effect, and you go on your way. Sure, there's an extra step, but it allows one character to be subordinated to another with less opportunity for stupid shit.
@faraday Highlighting your name because my response to Arkandel is basically my response to you.
Cooking meth would in most role-play I've ever been a part of be handled by saying, "My character cooks meth." and then rolling. The same goes with hacking, cooking, hunting and sometimes even combat with a simple "I swing my sword" or "I fire my shotgun". You can also google most practical skills like that and make a convincing pose if you had to.
Maybe my experience with this sort of thing is different, but I hang out with STEM people. If you say "I cook meth," and then you follow it up with something that's incorrect to the end of cooking meth (like my "mix ammonia with bleach" example), they'll call you on it. Even if a non-STEM person wouldn't be able to pick up on it, the people I spend my time will. So @faraday's expectation of a Hollywood-esque explanation wouldn't cut it because I spend my time with a pharmaceutical manufacturer with a background in chemical engineering, and he'd call you on it fast. I spend time with people who know what they're doing on a wide variety of topics, and if I get into even slightly incorrect specifics, their suspension of disbelief will be undermined dramatically.
That's why I can say "I cook the meth" and it will fly because I'm not specifying how. Basically, I think you're presupposing that the only thing that can be held to realistic standards is social interaction.
Lying, impressing, manipulating people is on the other hand almost always role-played out fully and responses to it must be role-played out fully as well.
I've seen people in my group say that they lie to the town guards and just roll a bluff check. They leave it at that. This is considered acceptable. I understand the desire to write elaborate poses to the effect you desire, but this can be accomplished with roll-first-pose-later without expecting people to be who they roleplay as.
