More about the course.
In this course, you'll learn the essentials of Assumption Hacking. What is Assumption Hacking? Well, it's a simple, practical approach to uncovering, challenging and doing something useful with the assumptions we make. It is a critical skill for solving problems, eliminating conflicts, learning from mistakes, understanding others, and understanding ourselves.
To challenge basic assumptions, we first need to expose them. But basic assumptions are mainly hiding below the surface, alive and well in our intuition, rarely verbalized. We make assumptions all the time. So how to know which ones need identifying, and then how to identify them?
