The Four Quadrants (Panes) of the Window
Open Area / Arena (Known to Self & Others): This is the public self; what you know about yourself and what others also know. It includes behaviors, skills, and attitudes that are freely shared.
Blind Area / Blind Spot (Known to Others, Unknown to Self):Things that others perceive about you, but you are unaware of. This might include habits, mannerisms, or how your behavior affects others (e.g., someone might not realize they are interrupting others).
Hidden Area / Façade (Known to Self, Unknown to Others): Things you know about yourself, but keep hidden from others. This includes personal feelings, secrets, insecurities, or fears.
Unknown Area / Unknown Self (Unknown to Self & Others): Aspects of the self that are not known to you or to others. This can include untapped talents, hidden motivations, or subconscious feelings.
