I had an argument with someone on OOC about this.
It's meta to ignore those stats, because you're using your OOC assumptions to ignore their IC stat investment. It's also very close to power posing.
I mean, to give an example of this turned in a physical stats direction,
If you're not fast in real life, your speed in game should be lowered because my assumption is that your character isn't fit because of your lack of fitness IRL.
If you can't lift the amount your character can lift in real life, good luck, cause I'm going to ignore your strength and power pose on you ignoring just how buff your character is.
An example was given to me in xooc, was that, "If a character with 1500 UE in int goes into the hall and tries to shoot it up, I don't care, that character is an idiot." Essentially stating that if you can't RP the stat, you shouldn't have it. And that to me is a shitty way to view the situation. That character doesn't suddenly become an idiot, because of a bad decision, that character is still Mr S. Marty Smart hyphen Pants with 1500 UE in int. He's just made a dumb decision. His actions don't invalidate that investment, and you(Speaking broadly here, not to the person who made this quote) shouldn't invalidate it either. Because to invalidate that investment, because of personal opinion on a character, is meta.
Invalidating it it essentially saying, I know OOCly that the player of S. Marty Smart hyphen Pants, is not all that smart... So I'm going to exploit that fact, and even though that's contrary to the evidence that I may have of S. Marty Smart Hyphen Pants being able to do that indicate S. Marty is a "Smart Guy," I'm going to treat S. Marty Smart Hyphen Pants as dumb. Because his skills and choices as a player invalidate his choices of investment for his character. Which is a textbook definition of meta.
Using OOC (Out of Character) knowledge IC (in character)
All of this applies for the other soft stats of Luck and Charisma as well.
In this case, the people claiming there is no problem and that they should be allowed to RP as they will, without hints, or suggestions that would indicate in the proper direction for RP, are actually feeding a very real problem that they are denying exists. As they are asking for permission and tacit approval to essentially continue ignoring stats as they come up, and to continue using their OOC opinions to conclude and make something factual for them, ICly.
1. This thread and similar conversations should make very apparent that there is a problem occurring, as players on one side are saying there is a problem, because people are ignoring stats, and people on the other are saying, to paraphrase "Yeah we're ignoring stats, but -reasons-"
2. Ignoring stats in favor of your OOC opinion on a characters actions is Meta by definition. Especially with regards to Charisma. As charisma is a measure of not just appearance, but of likability which is a very important point.
3. Expecting staff to police every player at all times on this is a hard issue to measure as it relies on staff to basically make judgement calls that the PC's and players themselves should be making. And might actually lead to a lot of arguments that staff would find annoying.
4. A simple solution would be a line when a particularly low or high charisma character enters the room, indicating just how high or low their charisma or charm is. Drawing attention to themselves in a way that such deviations from the norm would have occur. Or if they address you maybe, have a quick line added to it, that indicates social pressure.
