The answer is:
Freud believed that the unconscious mind had the "greatest" effect on our behavior.
The unconscious personality comprises mental procedures that are distant with cognizance anyway that impact feelings, perceptions and conduct.
As stated by Freud (1915), those oblivious personality may be those elementary sour ball of mankind's conduct. Like a iceberg, the essential part of the mind you can't perceive .Our motives,emotions and choices are really influentially impacted by our previous experiences, what's more put away in the oblivious.
