Consider the following statements about the Johari Window model:
I.   The "Blind Spot" quadrant contains information that the individual is aware of but deliberately withholds from others to maintain a strategic advantage.
II.  Expanding the "Open Arena" requires both self-disclosure (reducing the Hidden quadrant) and actively seeking feedback from others (reducing the Blind Spot).
III. The "Unknown" quadrant represents untapped potential and unconscious behaviours unknown to both the individual and others, which can be revealed through experience, coaching, and group exploration. Which of the above is/are correct?
