Critical thinking

Critical thinking is a relatively well-developed domain focused on decision making and the impact of biases and fallacies, with lots of great resources you can use to learn. It’s truly essential to any managerial work, including project management, but it can be useful in any aspect of your life as well.

We can see critical thinking as one aspect of systems thinking, which is the subject of this principle. At least, this is the categorization used in the PMBOK Guide.
