No.
Crap. That makes this statistically less possible then.
Rule Clarification: If Doppelgangers are in fact real, there will be 3 Doppelgangers. Not 2. 3.
This rule is BS. If there are 3 Doppelgangers, that means 1/3 of us are Doppelgangers and not the 25% you claimed (2/9 = 22.2%, 3/9 = 33.3%). This also means there is almost no way to win this game unless there are, in fact, no Doppelgangers, except through pure luck and analysis.
Simply put, there IS a way to at least give us some information. We could've had two people vote each other.
What this does is give us a little information: If one of them is a Doppelganger, then the Doppelganger is lynched. If both are Doppelgangers, neither are lynched. However, if both are human, that means one of them is lynched and we all lose the next day.
So, there's really no way to win by lynching, except if Doppelgangers are real. If they are real, we can win by lynching. However, this makes no sense, since we cannot assume such things. Therefore, there will be no lynching ever in this game.
Do not vote to lynch. If you vote, I will have to kill you, through sheer analysis, questioning, and overbearingness.You will single-handedly lose the game for us if you vote, and I will make you suffer for doing that.
DO NOT INVOKE THE WRATH OF WEBADICT!Therefore, we're going with analysis and playing this game with what little information we can't gather. Therefore, I'm not claiming this to be more of a guessing game than anything else, and that guess is that Humans exist, since it would totally be like SC to make a game like this to make us assume Dopps exist. As well, he seems to have completely missed the part of himself giving a completely wrong percentage to the Doppelgangers, something I wouldn't assume of him.
So, just a note:
Dopps don't exist. This will be my thinking until someone can give a better scenario.
