This course is for anyone who uses AI tools regularly — or plans to — and wants to do so without being misled by them. Unlike courses that treat critical thinking as a philosophy lecture, this one is built around the specific, practical challenge of navigating a world where AI-generated content is indistinguishable from human-written content at a glance. The tone is direct, the examples are real, and every chapter ends with something you can actually use. The course unfolds across three sections. Section 1 builds the diagnostic foundation: you'll understand exactly how large language models work, why hallucinations are architecturally inevitable, and why your brain is wired to trust fluent, confident-sounding text — even when it's wrong. Section 2 hands you the full toolkit: source evaluation, logical fallacy recognition, bias identification, statistical literacy, and argument construction, all reframed for an AI-native environment. Section 3 puts everything into applied practice — AI in the workplace, synthetic media, high-stakes decisions, persuasion and manipulation, and how to pass these skills on to others. By the end, you'll think differently about every piece of AI-generated content you encounter — not with blanket suspicion, but with calibrated, efficient skepticism. All figures, statistics, and AI capability benchmarks in this course reflect 2025–2026 data.
