Psycho-Sleuth · Investigation & debate
A repeatable process for searching the room and responding to statements under time pressure.
Record two kinds of information
Keep physical observations separate from claims made by witnesses. For each statement, record who said it and what they could actually see or hear.
Accept or contradict
During a debate, judge the statement before choosing evidence. Accept a statement that fits the facts; when there is a contradiction, select the clue that directly challenges it. The debate timer makes preparation useful.
Test a belief against the room
Not lying is different from knowing the truth. Check what each person witnessed, what happened out of sight and which conclusion they inferred afterward.
