Lie Detection: > [name] are you [mafia/town]? Less than a 1 second delay means anticipation of said question, often implying guilt. It takes around 500 milliseconds to process environmental input and another 500 to deliver a response, so if a person answers, "no" within a second or two (depending on typing speed), then they're most likely truthful. If they delay any longer or deflect the question, then they're likely lying. I made sure you were present before I asked if you were mafia, to rule out any false positives from you being AFK. More time can be given if someone types more than a simple, "no", but you have to look out for speech patterns that guilty people use. Saying, "nah", or longer versions than a simple, "no", is often an indicator of guilt. Repeating that they're blue usually yields the same results.
>Contractions These are shortening of multiple words like, "do not" into, "don't". Much like the rest of these techniques, you need to figure out a baseline of the person you're testing. A baseline is how people act/type when they're known to be answering truthfully. People usually stick with either using contractions or not using them when they're truthful; with the exception of emphasis on a statement. If you know which a person uses when they're being honest, then the presence of the opposite in a sentence can mean they're lying.
>Periods Like the contractions method above, establish a baseline of a person as to whether or not they use a period at the end of a sentence when they're honest. Any further sentences from that person with the opposite of what they usually use can mean they're lying.
Mafia Detection: >First to Vote/Talk While this may mean a person is eager to play, it can also mean that a person was in a mafia meeting at night, since partners usually talk and take longer to hammer than non night-meeting players.
>Grudge Kills When a person dies first, it can be random, or it may indicate the mafia played with that player in a previous game. By checking the last few games of the person who died first, you may find useful information on people to focus your attention on. I.E. if the player who died was cop in a previous game, who won, then the mafia from that game might kill him in the game they're currently playing.
>Adjacent Voting Interestingly enough, mafia partners take subconscious cues from each other. This can manifest as a less experienced partner voting directly after their partner votes.
>Manic Behavior Sometimes the Mafia based roles will talk excessively during the day, in an attempt to not seem "lurky".
>Tangents To deflect pressure and/or guilt, Mafia sided players are more prone to talking about things other than the game at hand. Also, the more details they give, the more they're under pressure.
PR Detection >First to vote PRs usually have night actions, so they know they're a PR. This will make them excited and anxious, so they sometimes will be impatient and quick to vote.
>Vote-Tailgating Since PRs generally do not want to out themselves at first, they will try to be subtle in all their actions, but that comes across in different ways. They may quick-vote directly after someone else votes, as to not draw attention to themselves.
Enjoy!
