- The shock was considered "mild". - "didn't like" was based on paying some part of an imaginary $5, not their money and not big money. I couldn't find how much of the imaginary money people would spend. $1 or $5, seems both were counted as "negative", despite a potential gradient in just how much someone disliked it. - There could be peer pressure to have a negative opinion of the shock because people would assume you would want to avoid being shocked, that's what a "normal" person would do. - People have different levels of pain tolerance. Those with higher tolerance may find the shock more interesting than painful. - The recollection of an event can diminish quickly, especially when being questioned about other things, while being left in a room with only the shock button would expectedly narrow their focus back to the shock they had received earlier, likely triggering further curiosity about their shock tolerance. - While being shocked as prep for the "test" is part of the story, the other half of the story is being left in a room with the shock button, and people are going to want to know if you shocked yourself or not.
