Have you ever played 20 questions with one of those "stories with holes"? I remember as a kid I had a teacher pull some of us aside to challenge us with these while the rest of the class worked on something we had already mastered. The idea was to tell a story with seemingly neutral facts and with a key part of the narrative missing so that by asking 20 or less yes/no questions you could deduce the key to the narrative. Almost always, the seemingly neutral description contained a critical clue that triggered the game-players' assumptions in a way that led them down a false path, and hindered their deductive process until they could hone in on the assumption, question it, and break out of the consequences of the assumption. Maybe a few concrete examples, if I can remember some: A man is driving in his car and is killed by a gunshot, but there's no hole in his vehicle. Most people start asking about whether the windows were open (nope, all closed up), and about passenge...
Candid evaluation of assumptions as well as musings on consequences of political, religious, moral, scientific, linguistic and literary truths and pretensions thereto. Dissecting representations, critiquing arguments, discussing liberty, equality, justice, faith, values, facts, and the principles and institutions that make them all possible.
