But actually, the reasons they're back are somewhat similar to that, because there's a certain steadiness to the idea that if you answer a question with the right answer, you win money. Precision in answering, knowledge, and money are big factors in human society. I think that's part of it.

Someone wins and someone loses, and it's heartbreaking when people lose.
They feel terrible. I can tell you from having dealt with them every day for a long time now. They feel terrible. The winner feels great. There's real exultation, real despair.
