One of the most important areas of background knowledge that critical thinkers need to develop is background knowledge surrounding human nature and how the human mind works.

The videos in this address of the most important sub-topics within this broad topic: cognitive biases and the nature of human (ir)rationality.

The goal, again, is to develop a level of literacy around these topics so that we can think and talk about errors in reasoning that we're prone to make, and what we can do to reduce our susceptibility to those errors, or at least the negative consequences of committing those errors.
