Let's say 50 people of the same type were gathered together in one room.
ENTP - debate team. big yelling match (I'm inviting disaster)
ISTP - utopian society. just kidding. not sure what would happen, but I know that room would never look the same afterward.
tell them it's a prison, that room is on fire in < 5 minutes.
ISTJ - stand in rows. don't talk. wait for orders.
or do combos of 25 and 25
ENFP/ISFP - "You're so nice." "No, you're nicer." "No really, you're SUPER nice." "Aww thanks, but really, you're the nicest."
