This course contains the use of artificial intelligence.

Most teams confuse harmony with effectiveness, and pay for it in bad decisions that everyone privately doubted before the meeting ended. Groupthink, the Abilene paradox, and false consensus are not theoretical curiosities — they are everyday failure modes inside organizations that have not learned how to argue well. This course treats productive disagreement as a core professional skill rather than an interpersonal nuisance, and teaches you how to build the habit of challenging ideas constructively so that your team consistently reaches better conclusions.

You will learn the fundamentals of argumentation, including how to construct claims with evidence and warrants, qualify your assertions appropriately, surface hidden assumptions, separate correlation from causation, and recognize the logical fallacies that wreck business discussions. You will then learn the major structured debate formats used by high-performing organizations, including red team and blue team exercises, pre-mortem analysis, devil's advocate protocols, and dialectical inquiry, along with a framework for choosing the right format for each decision. The course covers the interpersonal craft of disagreeing well — separating ideas from identity, applying the steel-man principle, asking genuine rather than leading questions, conceding gracefully, and listening to understand rather than to rebut.

The course then puts these skills to work in the specific workplace contexts where they matter most, including strategy decisions, product reviews, technical architecture debates, budget allocation arguments, and hiring calibration. You will learn how to create psychological safety that makes challenge possible, how leaders signal the norms that determine whether a team's culture welcomes dissent, how to repair relationships after heated debates, and how debate norms vary across cultures so you can adapt your style across contexts. You will also learn how to advocate upward against power without putting your career at risk, and how to challenge ideas hard without undermining the people who hold them.

This course is designed for managers, team leads, product managers, executives, and any professional who participates in or facilitates group decision-making. If you are tired of meetings that end in agreement and weeks later in regret, enroll now and build the debate skills that distinguish teams that decide well from teams that merely decide together.
