Null

The word "null" is normally used as an average between "town" and "scum".

Describing a player's action as "null" means that you believe that that action gives no useful information towards determining that player's alignment. The phrase "non alignment-indicative", sometimes abbreviated to "NAI", has the same meaning.

A "null read" on a player is a belief that that player is no more likely to be town or scum than average. This might be due to a complete lack of alignment-indicative information, or else conflicting information about that player's alignment that mostly cancels itself out.
