Johari Window

The Johari Window, created by psychologists Joseph Luft and Harrington Ingham in 1955, is a framework for improving self-awareness and interpersonal relationships. It maps what you know about yourself against what others know about you, revealing blind spots and hidden areas.

The Johari Window has four quadrants:

1. Open Area (Arena) — Known to self AND known to others. Your public knowledge, skills, and behaviors. The bigger this area, the better the communication.
2. Blind Spot — Unknown to self BUT known to others. Things others notice about you but you don't see. Reduced through receiving feedback.
3. Hidden Area (Façade) — Known to self BUT unknown to others. Things you know about yourself but haven't shared. Reduced through disclosure and trust.
4. Unknown — Unknown to self AND unknown to others. Undiscovered potential, unconscious behaviors. Discovered through new experiences and deep reflection.

• Reduce Blind Spots: Actively ask for feedback. Listen without defending.
• Reduce Hidden Area: Share more about yourself, your thoughts, and your feelings.
• Reduce Unknown: Try new things, seek diverse experiences, reflect deeply.

• Open: Strong technical skills, direct communication style, values deadlines
• Blind Spot: Tends to interrupt people in meetings (team notices, they don't)
• Hidden: Feeling overwhelmed by management responsibilities (hasn't shared with team)
• Unknown: Potential talent for mentoring junior developers (hasn't had the opportunity)

The Johari Window helps you build trust and improve communication by systematically expanding what's openly known between you and others. The goal is to make the Open Area as large as possible.
