 I'd like to welcome you to Think 101, the science of everyday thinking. This is the third time we've offered the course. In the first run of the course, we've had, since the first run of the course, we've had about 300,000 people in role. And we've interviewed some of the best people in the world, from Danny Kahneman, a Nobel Prize winner, to the Mythbusters, Elizabeth Loftus, Susan Blackmore. And you're going to hear some of these conversations that we've had with some really incredible people about the science of everyday thinking. So we're going to talk about things about the illusions of thinking, how to think more rationally, some of the tools for thought, and how to improve your everyday decision making. I hope you enjoy the course as much as we enjoyed putting it together. Since we offered this course back in 2014, we've since put together a podcast. So if you enjoy the content within this course, I encourage you to subscribe to the podcast as well. It's called Think 101 Conversations. So enjoy that as well, and enjoy the course.
