Definition
- The Appraising Law (Law of Incentive Multiplication) holds that praise is a powerful, low-cost motivator: what it costs you to give sincere appreciation is far less than what the praised person gains from it.
Core Idea
- Praise costs the giver little but means much to the receiver.
- Recognition multiplies motivation out of all proportion to its cost.
- Sincere appreciation is one of the most efficient incentives available.
How It Works
- Genuine praise meets a deep human need for recognition.
- The receiver gains confidence, motivation, and goodwill far exceeding the effort to praise.
- This asymmetry makes appreciation an unusually high-return management tool.
Usage Example
- A manager who regularly and sincerely acknowledges good work finds motivation and morale rise sharply — at virtually no financial cost.
Famous Example
- Example: Attributed in management writing to "Peter," advocating praise to motivate employees because the giver spends far less than the receiver gains.
- Why it fits this rule: It states the incentive-multiplication property of praise directly.
- Verification status: A management adage; the specific attribution is unverified, though the power of recognition is well established.
Use Cases / Situations Where It Applies
- Recognition and motivation.
- Low-cost incentives and morale.
- Leadership and feedback.
When Not to Use or Common Misuse
- Do not give insincere or indiscriminate praise — it loses value.
- Do not use praise as a substitute for fair pay and real opportunity.
- Do not praise only outcomes; recognize effort and behavior too.
