One guard lies. One guard tells the truth. One guard thinks he's telling the truth but operates from deeply unsound epistemological principles that were inculcated by his elders to steer him to specific predefined conclusions, he's not lying but nothing he says is as actionable as he thinks it is. One guard is honest but he's got that thing where he keeps confusing your left and right with his left and right, and even when it's just him he's always got to stop and think for a second to remember which is which, and long story short he's never once said the correct door on the first try. One guard says whatever the first guard to speak says because he's afraid of being left out. One guard claims the opposite of whoever was first to speak because he's a contrarian. One guard does that fuckass postmodern "what is truth" song and dance because he doesn't actually know which door is the correct one, he lost the briefing packet and for obvious reasons he can't pick a door to check in person. Defeats the whole point if you can come back
