David K. Levine is a person who does a lot of thinking about how people make decisions. He likes to imagine that people are playing games all the time, and that different choices they make in those games can lead to different outcomes.
For example, let's say you and your friend are playing a game where you have to choose between sharing your candy or keeping it to yourself. If you both share, you both get a treat. But if you both keep it to yourselves, you both miss out. If one person shares and the other keeps it, the person who kept the candy gets a treat but the person who shared doesn't.
David K. Levine thinks about these kinds of games a lot, but he also thinks about more complex games that involve lots of people and lots of decisions. He says that people don't always make the best decisions in these games, because they don't have all the information they need or they don't fully understand what's at stake.
So, David K. Levine tries to come up with ways to help people make better decisions in these games. He also studies how people's behaviors change when they are playing against other people versus playing against a computer.
Overall, David K. Levine is someone who thinks a lot about how people make choices and how they can make better choices.
