Mona, Mylinh and Moe introduce cognitive biases and logical fallacies in the following sequence, Availability Heuristic, Barnum Effect, Automation Bias, and Groupthink. We start with the introduction of our podcast. For each of them, we talked about definitions, examples, how we can apply in real life and so on. We conduct a questionnaire on psychological phenomenon of bias, Groupthink and we talked about what questions we have set and what we learned from it in our talk. The last part is the conclusion of it and the purpose for our talk.
