The way I play nowadays, I'm often aiming deliberately to
not
be charismatic--I don't
want
people to follow me most of the time, because in spite of how hard I push my read, in spite of how many points I raise (and I wouldn't raise a point I didn't believe was a good one; every point I raise I feel is a valid one), I have doubts on whether my point (no matter how good the point may be) is
right
, and because of that, I have doubts as to whether my entire push is right.
I deliberately hide this, so it looks like I am pushing with absolute 100% certainty my target is scum, but it's a facade and underneath is the me that is less sure of the read. You can tell that these reads are less certain, because I am going out of my way to avoid trying to actually lynch my target; I will keep stating a person is scum, without really activating my charismatic side.
Because the
actual
key to charisma, is to know your audience and write things as close to their perspective as is possible. Use THEIR reasoning, THEIR process, even if it is alien to you, even if it is foreign and seems wildly off-base to you, and turn it around. Find the weaknesses in their opposing viewpoint, not from YOUR view, but from THEIR view, point out THEIR narrative's contradictions: "Okay, so you think that X means Y for Z. Why not for A?" Get them to flesh out why point A applies for person B, but not C, and then make your argument for why point A is
better
applied for person C, rather than person B.
In other words, you don't get progress by telling them their points are wrong; their reads are wrong. You get progress by telling them their points are right, but being misapplied; you get progress by telling them their reads are mostly right, but they went off-base when they made this mistake here, and you guide them through THEIR logic, THEIR reasoning, as to where they went wrong--not your own.
And you do this for every player you try to convince, while adding in your own thoughts as is necessary, but your own thoughts aren't so much for convincing others you're right so much as they are to convince others that you have a genuinely unique, original perspective with a town origin. (In other words, showing your own thoughts is a good way to be open, sincere, genuine, enough to earn a townread and become obvtown; it is not part of becoming charismatic.)
It's a hell of a lot of effort though, and it requires a specific tone.
Accusing them? Backfires.
Insulting them? Backfires.
You have to be nice, gentle, kind, like a teacher, guiding students through their work. Put yourself into that role, of someone who is trying to teach people not by telling them the answers, but by letting them find the answers on their own, because answers found on their own stick much better and longer than answers you just hand them out.
Like I said, most of the time I don't bother, but the rare times I do, this is the process I use and I can tell you it works.
