The post that you replied to - which reply I then responded to - was from @TwoSix. And it talked about "put[ting] something into the game that's not changeable by the game's resolution method".I was talking about skill rolls in games that have them for social skills. I wasn’t talking comprehensively about all social interaction rolls.
You then replied by characterising resolution methods other than the GM deciding as "mechanical widgets". So were you strawmanning TwoSix? Or something else?
I mean, if you're aware that good social resolution methods don't have the features you're criticising, why are you posting as if those good methods don't exist? It's confusing to me.
