> Gives you a sense for if they think independently. Call them out if what they say is something you’ve heard before or 30%+ of the people in the room would agree with what they say is their most “radical” belief.
This isn't a measure of independent thinking, this is whether they're a complete nutjob.
I saw a version of this question in a book once and it stuck with me: "What important truth do very few people agree with you on?"
Obviously, never asking this when first meeting someone but further down the line, once you are comfortable with each other.
Does having an answer to the question phrased as such still make you a nutjob?
Personally, I value individuals that are able to ponder on this question for a while and provide a valid answer.
