According to traditional psychology, there are four stages of learning:

Unconsciously incompetent (i.e. you don’t know what you don’t know)
Consciously incompetent (i.e. you know what you don’t know)
Consciously competent (i.e. you know what you know)
Unconsciously competent (i.e. the things you know go on auto-pilot)

Wikipedia credits this to Martin M. Broadwell  who first articulated the model in his “four stages of teaching” in February 1969.
