The Johari Window

What is the Johari Window and how do you use it for self-awareness and communication?

The Johari Window, developed by Joseph Luft and Harrington Ingham, is a model of self-knowledge and interpersonal disclosure organized into four quadrants: Open (known to self and others), Blind (known to others, not to self), Hidden (known to self, not to others), and Unknown (known to neither). It is used in coaching and organizational development to guide feedback exchange and self-disclosure, expanding the Open area and reducing blind spots.

Joseph Luft and Harrington Ingham created the Johari Window in 1955 as a heuristic for exploring self-awareness and interpersonal dynamics in group settings. Its enduring usefulness is that it names the specific ways our self-knowledge is incomplete: we have blind spots others can see; we have hidden information others can’t; and we have unknown potential that neither we nor others can yet access. The practices here apply the window practically — through structured feedback, deliberate disclosure, and challenge — to expand the Open area and reduce the costs of blindness.

Practices

Map your Johari Window with a trusted person

Identify what is open, hidden, and blind in a specific relationship or role.

Actively seek feedback on your blind spots

Ask specifically for what others see that you might not — with enough specificity to get honest answers.

Expand the Open area through deliberate self-disclosure

Share what you know about yourself that others don’t — reducing the Hidden quadrant.

Receive feedback with minimal defensiveness

Treat feedback as data about others’ experience — not as a verdict on your character.

Expand the Unknown quadrant through challenge and experience

Try things outside your current self-concept — undiscovered capacity lives in the Unknown quadrant.

Use the Johari Window in team settings

Apply the window at the team level to improve shared understanding and reduce inter-member blind spots.
