To elaborate -- are the wrong answers that arise through stupidity, being ill-informed, or being careless similar to or totally different from the wrong answers that arise when the material is just very difficult? Can those who see themselves as above-average in intelligence, informedness, and carefulness learn something from a video like this? Are important decisions of rationality ever made in this type of time pressure? What is the influence of making the decision under the glare of a hundred people (live) or a million (tv)?
