Some types of learning occur implicitly, that is without conscious awareness. Other types of learning are very easy, and other types of learning are effortful, perhaps even painful and aversive, such as learning the names of the facial nerves or how to do long division. It is only after they invest in the hard work of learning that additional learning in these fields becomes easy and more automatic. There is no single set of learning principles that will always work. The best way to learn and recall something will depend, in part, on what it is you want to learn and recall as well as what you already know.
Experience alone is a poor teacher.
There are countless examples where what we learn from experience is, in fact, systematically wrong. For example, most jurists believe that they can tell from a person s demeanor whether she or he is telling the truth. In fact, they cannot. If a client does not improve, then therapists reason that he or she was too sick to benefit from the good treatment. There are countless examples of this sort of erroneous thinking, where our beliefs about the world are maintained and strengthened despite the fact that they are wrong.
