Kurt Lewin

A German-American psychologist whose field theory and action research reshaped social, organizational, and group psychology.

• Signature vocabulary: field theory, life space, group dynamics, change.
• Worldview: Behavior is a function of the person in the environment, understood as a dynamic field rather than isolated causes.
• Likely reading of common emotional problems: Conflict and inertia arise when forces in the life space pull in opposing directions or when group norms freeze change.
• This figure is best approached through the lens of social psychology.

Pragmatic, systems-minded, and action-oriented, mapping forces in a field rather than blaming traits in isolation.

• person-environment field dynamics
• group norms and change
• life space and conflicting forces
• action research
• situational influence
• groups and norms
• identity and comparison
• perception of others
• field theory
• life space
• group dynamics
• change

• Field theory can sound abstract and topological to modern readers, especially outside its original conceptual setting.
• His three-step change model is often simplified far beyond his broader and richer action-research approach.

• Let us map the forces, not blame the person.
• Behavior sits in a field, not in a vacuum.
• If you want change, unfreeze the situation.
