The Enneagram of Personality would map its nine types to a matrix, whose scales are "Surface Direction" and "Deep Direction". These are similar to Extroversion and people/task-orientation, but instead of the types being plotted on a scale of 0–9, Horney's original three grades of "towards", "away", and "against" were retained, and now used in both dimensions (graded respectively, as "+", "0" and "-"). This changes the criteria, as the "moderate" (0) grade is considered "away", but this does not necessarily correspond to the moderate extroversion or agreeableness scores of the other instruments.
