 So one of the things we're trying to do in this course is give a realistic idea about how the mind is actually working. So we can take that and use it to improve our ability. The world is extremely complex and extremely ambiguous, right? So most of the decisions that we're making aren't immediately apparent. There is a lot of mental life that is completely effortless and then there is some of mental life that feels like work. We're operating under less than ideal conditions and so we have to rely on shortcuts in order to be able to navigate the world, obviously. The world is complex and ambiguous. There's so much information coming at us, sometimes misinformation. How do we deal with it all? So merely telling people how to do something is not going to turn them into experts and repeatedly telling them the same thing is not going to help. There's a lot of practice with feedback.
