Definition

Uznadze's Law holds that without need there is no motivation at all — motivation arises from a felt need, and where no need exists, no drive to act will follow.

Core Idea

Need is the root of motivation.
No need means no genuine drive to act.
To motivate, connect action to a real need.

How It Works

People act to satisfy needs — physical, social, or psychological.
When a need is absent or already met, the corresponding motivation disappears.
Effective motivation therefore works by awakening or addressing a real need.

Usage Example

A manager trying to motivate a comfortable, fully satisfied employee finds incentives fall flat — until they connect the work to a need the person actually feels.

Famous Example

Example: Associated with the Georgian psychologist Dmitri Uznadze, known for his theory of "set" (ustanovka) and the role of need in shaping behavior.
Why it fits this rule: It ties motivation directly to the presence of need.
Verification status: Uznadze is a real psychologist whose work centers on set and need; the exact "law" wording is a popular distillation.

Use Cases / Situations Where It Applies

Motivation and incentive design.
Understanding behavior and drive.
Marketing and persuasion (creating felt need).

When Not to Use or Common Misuse

Do not manufacture false needs manipulatively.
Do not assume the same need motivates everyone equally.
Do not ignore higher-order needs once basic ones are met.
