Gut reads based on scum or town motives d1 to put people in tiers. Based on that adjust accordingly to solve based on logically conclusions as players play evolves.
As
@The Orca has said before (in a different context), peoples play will usually out them as the game progress
For instance, kiku playing it down the middle last game then taking a 180 in lock step with you. It outted you both clear as day (i was right about that, just wrong about actual alignment and roles)
At the same time, Naomi become reserved as fuck during that one mini game where she played coy with me and balked at answering me straightforwardly. Its why I shot her thinking she was scum. From that point forward she changed and was far more reserved (wish I would have not been distracted from that by ekko lol)
