We’re all gonna die someday. But can statistics help us know when? In this episode of Crash Course Scientific Thinking, we’ll learn how to interpret the statistics we see in our daily lives.

Crash Course Scientific Thinking Preview

13 jan 2026

Science is one of the best ways we have of understanding what’s going on around us. In Crash Course Scientific Thinking we’ll explore the foundational principles that underlie scientific thought. Course Description In 7 episodes, Crash Course Scientific Thinking will teach learners the foundational principles underlying scientific thought, pulling back the curtain on processes like peer review, interrogating what makes sources reliable (or not), unpacking how consensus is reached, and revealing how scientific understanding changes over time. Ultimately, learners will gain the ability to think more critically about the scientific information they encounter in their everyday lives. Series Objectives - Describe the dynamic, communal nature of science, articulating the roles of uncertainty and consensus. - Explain the role of peer review and replication in science. - Unpack the potential for bias and error in science and understand its self-correction mechanisms. - Understand the role of specialization in scientific expertise. - Interpret primary, secondary, and tertiary sources, and use lateral reading to verify claims. - Understand basic statistical language used to describe scientific findings.

How Should AI Be Governed?: Crash Course Futures of AI #5

17 dec 2025

The future of AI is maybe beautiful, maybe scary, and definitely uncertain. But we do have a say in how it rolls out. From lab policies to international treaties, people all over the world are trying to figure out how to build and use AI in safe, responsible ways. But when the stakes are so high, can humanity really come together and keep AI under control? Chapter 1: Sam Altman & OpenAI 00:00 Chapter 2: Lab-level AI governance 1:13 Chapter 3: National AI Governance 5:07 Chapter 4: International AI Governance 8:40 Chapter 5: Review & Credits: 10:48 About This Series: AI is changing FAST so rather than doing a full Crash Course series of 12+ episodes, we’ve prepared a mini-series of just the basics. Crash Course will never tell you what to think and we’re not the type of organization that responds to breaking news in real time. Instead, we’re here to offer a zoomed-out foundation upon which to base your own opinions as you continue to learn from other outlets about the world that’s changing around us. Crash Course: Futures of AI will cover: -What even is AI? What’s the history of this thing and how quickly has it evolved to what exists today? -How could AI transform society? Will AI cause the next Industrial Revolution, and what might that mean for workers and the environment? -How powerful could AI become? How do we measure the progression of AI? What are the consequences we’re already seeing, and what might be the future consequences of unchecked AI development? -How might powerful AI cause harm? We’ll touch on copyright infringement, misinformation, surveillance, authoritarianism, and (unfortunately,) more. -How could AI be governed? What are the potential approaches for controlling AI both nationally and internationally? P.S. Wondering if we used AI to create this series? Nope!

Instead, we’re here to offer a zoomed-out foundation upon which to base your own opinions as you continue to learn from other outlets about the world that’s changing around us. Crash Course: Futures of AI will cover: -What even is AI? What’s the history of this thing and how quickly has it evolved to what exists today? -How could AI transform society? Will AI cause the next Industrial Revolution, and what might that mean for workers and the environment? -How powerful could AI become? How do we measure the progression of AI? What are the consequences we’re already seeing, and what might be the future consequences of unchecked AI development? -How might powerful AI cause harm? We’ll touch on copyright infringement, misinformation, surveillance, authoritarianism, and (unfortunately,) more. -How could AI be governed? What are the potential approaches for controlling AI both nationally and internationally? P.S. Wondering if we used AI to create this series? Nope! Every Complexly video is lovingly, painstakingly human-made.
