133 To answer your question, I always figure it's best to ask another question: If someone on your team is playing badly, does removing them make your team more likely to win? Town's advantage is the number game for awhile, as possible people who have which roles are wittled down. I think he's not playing good for a vanilla townie. And I actually answered that already on the 'why more likely as town than scum'. As a vanilla townie, you don't generally feel like you've agency. No matter what you do, it's not going to make an impact. Which is why it's inherently different than someone who's mafia. They're aware of the information and their goal is to be hidden, not disregarding. While you're right that scum are capable of deciding they dont care about the game, it's _far more likely_ that it's a townie play. Nothing in this game is about absolutes, as much as it's about what's likely.
Regarding
134 I disagree. Openly speculating on someone being vanilla or not does not give any more information to the mafia than they'd already have.
The game state at the start begins with each townie knowing only one thing -- out of 9 people, only they are innocent. Mafia know that 2/9 people are mafia. Speculating if someone is vanilla in public doesn't change the way the mafia works in that regard, they already know the most important part of the person you're thinking about -- they're not mafia.
Saying X is vanilla only leads to 4 outcomes.
You're right, and the mafia don't kill him -- You've a townie still.
You're right, and the mafia kill him -- A vanilla is dead. Still bad, but not the worst.
You're wrong, and the mafia kill him -- Not likely since if we're working on the assumption that mafia want to ginore the vanilla to hit 'power roles' this one would, by your own reasoning, show up the least (since a players input says their vanilla and by inference, the mafia has accepted that).
You're wrong, and the mafia don't kill him -- You might have confused a power with a vanilla, but the mafia are buying it.
Out of the 4 options (though really, 3 -- since the 'wrong and mafia kill him goes against the premise') 2 of them are in town favour. So you either have something that's useful 50% of the time, or realistically, 66% of the time.
Of course, this flips when you speculate about someone being a power role. I agree with you on the openly speculating power roles.
If anything, making more ideas on about who is and isn't town narrows the pool. Regardless of who dies tonight, from both lynch and kill, the game state will change. If the mafia ignore Gyro since they're aiming for a power role, they've still a 2/6 instead of a 2/7 chance of hitting right. But our possible pool of people we know that aren't mafia increase by 1, from the 1/9 at night 1, to (assuming lynch and kill) 4/9 on day 2. And a 1/5 shot is a lot cleaner than 1/6.
