It's one thing to get a question wrong that most people get right when the question is simply asking for a fact. You can always defense-mechanism it away (that's a verb) by telling yourself things like, "Oh I haven't studied that section that well yet" or, "Oops I misread the question."
But last night I got an ethics question wrong that 78% of people got right!! An ethics question! And apparently it was obvious enough that a vast majority of people knew the answer. What does this say about me??
