text: There is a phenomenon known as the Dunning-Kruger Effect, whereas there is a threshold of the knowledge someone may have that grants them much confidence in their manner of speaking in that area without a legitimate amount of knowledge in that area. Put otherwise, people learn enough information to think they're right without knowing enough information to tell if they're wrong. In addition to the Dunning-Kruger effect, there is a sort of hierarchy of skill set well know in psychology. In the bottom of this hierarchy is an unconscious lack of skill, followed by a conscious lack of skill, proceeded by conscious skill and topped with unconscious skill. While as a whole this measurement of skill is very interesting, all we need to know now is that the only way to move from an unconscious lack of skill to a conscious lack of skill is through a teacher because we cannot find ways to improve ourselves if we don't know there's anything to improve. The same could be said for overcoming the false confidence one may feel via in the Dunning-Kruger Effect. In combination of these two things, one can see why having advice from an external force in general is so necessary.
