Annie Duke, a former professional poker player and decision-making consultant, discusses the inspiration behind her book, "Thinking in Bets," and explores the challenges people face in making sound judgments, as well as how to improve one's decision-making process.
Duke explains that her interest in decision-making stemmed from her academic background in cognitive science, where she studied how our brains process information. After a temporary departure into professional poker, she realized it served as a natural laboratory for studying decision-making under uncertainty. She observed that even in a setting with rapid feedback, people often struggled to learn from their mistakes. This realization fueled her desire to help others make better decisions by merging her poker experience with her academic knowledge.
She points out that a significant problem in decision-making is uncertainty, which arises from hidden information and the intervention of luck. While perfect information is rarely available, even with complete information, luck can influence outcomes. She also noted that humans are not very good aggregators and often make decisions based on one-trial scenarios instead of waiting for more data.
Duke elaborates on the evolutionary roots of decision-making errors. She highlights the prevalence of type 1 errors (false positives), leading people to perceive causal relationships where none exist. Humans are inherently tribal, which creates problems in processing information from outside their group. Lastly, individuals tend to confirm pre-existing beliefs rather than disconfirming them. This combination of factors contributes to the challenge of making rational decisions.
She emphasizes motivated reasoning, where people actively seek information that confirms their beliefs and discredit information that contradicts them. In particular, the problem of echo chambers arises when the group we belong to dictates which information sources are considered trustworthy. Duke recommends applying a principle called universalism, separating the messenger from the message, to evaluate information objectively.
Duke proposes thinking in terms of bets as a way to improve decision-making. She argues that every decision is a bet informed by beliefs about possible future outcomes. By recognizing this, individuals are forced to confront uncertainty and be more open-minded. Explicitly framing a decision as a bet encourages probabilistic thinking and prompts consideration of why one might be wrong.
When a bet doesn't work out, Duke advises against resulting, which is retrofitting decision quality to the outcome. She advocates ignoring the outcome as much as possible and focusing on the decision process itself. She also recommends forming a "true seeking group" to help identify biases, assess decisions before the outcome, and analyze decisions from different perspectives.
She discusses the skill and luck factors and encourages people to be like Phil Ivey, analyzing their mistakes even after winning, rather than attributing successes to skill and failures to bad luck. By focusing on the quality of the decision-making process, individuals can learn and improve, regardless of the outcome. It is also equally important to understand not just making a decision is a decision, but not making a decision in a period of time is equally making a decision, which calls on the thought process to be the same.
She highlights the importance of making decisions in a group because it's hard to see our own bias in our decision-making, others are better at spotting that bias a mile away. Creating a group is better because, these bias is infectious.
Finally, she suggests using Ulysses contracts, planning for future biases, and taking action in advance so future you has less influence in your decision-making.
