I chose to watch the behavioral economic interview with David Laibson. My topic is online poker, which involves an interesting combination of pure game theory and human irrationality. While online poker is typically more mathematical in nature than traditional poker, its outcomes are still very much impacted by human behavior driven by some sort of reward. One particularly interesting section of the interview was when Dr. Goodman and Dr. Laibson discuss whether human behavior could ever be predicted. He confidently asserts that developing such an ability is very unlikely. Given how much online poker leans on mathematical predictions, adding this ability would essentially 'solve' the game. But the inability to do so adds an additional element of randomness that is indefinable.
The image I have included depicts an example of a combinatorics-driven poker strategy, indicating the rates at which a certain position should play a given hand. Poker softwares are able to quickly calculate and compute optimal strategies on the fly (for online poker players).
Here is a brief paper outlining a few psychological drivers that are common in online poker.
