Whatever the participants' prior knowledge may have been, they will come to understand the topic more deeply as the conversation proceeds and as they think about it later. It is how people of all ages naturally learn together when none of the individuals is imposing a system of extrinsic motivation. The training then contrasts this natural learning through genuine communication with what typically happens in schools at all levels. Usually, the teacher or professor is believed to know which material the student should learn, how it is to be learned, and how to determine if the learning has succeeded. What is remembered tends not to transfer successfully to practical situations where no teacher is available to assign problems.
Some processes used in standard educational practice can have severe negative side effects.
For example, fear of being wrong is often learned very, very well. Teaching fear of being wrong, as a side effect of any effort to teach anything else, is a grievous error. Bertrand Russell, the eminent mathematician and philosopher, wrote that in order to be capable of discovering anything new one must be able to live with an unfinished world view. In general, the best way to learn how to do something is to do it, with guidance from someone who already knows how. In many cases it is the only way.
