To teach my students the fallacy of "I have nothing to hide", I simply ask them to tell the whole class about the last time they masturbated. It is surprisingly efficient, they immediately grasp it. I never had someone argues with me on the subject after that.
RE: https:// mamot.fr/@ploum/11707884238310 9177 I also agree with the more “safe for work” version left as a comment suggesting to ask people to share their debit card PIN with the entire class. As well as the points that when we go in a public restroom, we still shut the door of the toilet stall. Either way, it makes the point.
