A. Xiang Yu explained that his decision was a necessity to win the victory over the enemy while his soldiers didn't appreciate it as they watched the vessels burned. But his unusual decision would be validated on his battlefield and also in modern social science research. B. When facing choices of rival options, think about what Xiang Yu would do. C. This example from ancient times led to the experiment at MIT where Dr. Ariely teaches behavioral economics. The experiment showed that students couldn't bear to see their options vanish, even though it was clear they would profit from doing so. D. Students played a game that provided different amounts of money behind the three doors appearing on the screen. The rule was the more money they earned, the better player they were. E. According to Dr. Ariely, the students' desire was to avoid the immediate pain of watching options close. In life, such costs are often less obivious as the doors are closing slowly and people don't really see their future opportunities vanishing. F. In the game any door left un-clicked for a short while would vanish. Instead of ignoring the vanishing doors, the students rushed to click on them before they vanished, so they lost money in the end. G. Xiang Yu, a Chinese imperial general, ordered his troops' cooking pots crushed and their sailing ships burned after taking his troops across a river to raid the enemy. H. What price do we pay for trying to have more and more in life? Will we have more by always increasing options or will we have more with fewer, carefully chosen options? We should close certain doors in order to allow the right windows of opportuity and happiness to open. I. The experiment was about a computer game which eliminated the excuses for letting go. J. Only keep the choices that actually enrich our lives. K. Reduce the load and remember the lessons of door closers like Xiang Yu. L. Implement more prohibitions on overbooking and reduce options on our own.
