Explanation

What it is

The Reward Undermining Effect—also known as the Over-Justification Effect — describes the paradox in which external rewards (money, grades, prizes) reduce a person’s intrinsic motivation to perform an activity they already enjoy.

When the reason for doing something shifts from “because I like it” to “because I’m paid or praised for it,” the task begins to feel like obligation rather than play.

When to use it

  • Analysing motivational design in workplaces, classrooms, or apps.
  • Evaluating incentive systems that target creativity, learning, or voluntary effort.
  • Diagnosing declining engagement after introducing tangible rewards.

Why it matters

  • Understanding this effect protects cultures of curiosity and craftsmanship from short-term incentive traps.
  • When intrinsic enjoyment is replaced by external validation, long-term engagement, creativity, and psychological ownership deteriorate.
  • Balancing intrinsic and extrinsic motivators sustains authentic motivation—the key to resilient performance and meaningful work.

Reference

Definitions

  • Reward Undermining Effect

    A psychological phenomenon where external rewards reduce intrinsic motivation for an activity that was previously enjoyable or self-driven.

  • Over-Justification Effect

    The cognitive process underlying reward undermining, where individuals attribute their behaviour to external incentives rather than internal satisfaction.

  • Intrinsic Motivation

    The natural drive to engage in an activity for its own enjoyment, curiosity, or personal meaning.

  • Extrinsic Motivation

    The drive to engage in an activity for a separable outcome, such as money, praise, or status.

  • Locus of Control

    The perceived source of influence over one’s behaviour; when external rewards dominate, control shifts outward, weakening self-determination.

Notes & caveats

  • The effect is strongest when the activity was already intrinsically rewarding; offering rewards for dull or repetitive tasks may not cause harm and can improve compliance.
  • Unexpected or non-contingent rewards (e.g., surprise bonuses) typically do not undermine motivation because they don’t alter perceived autonomy.
  • Verbal praise can strengthen motivation when it affirms competence rather than control.
  • Real-world applications must consider contextual factors like personality, culture, and task type before generalising results.

How To

Objective

To design motivational systems that sustain intrinsic engagement while responsibly using extrinsic rewards — avoiding over-justification and its demotivating side effects.

Steps

  1. Identify intrinsic drivers
    Clarify what naturally makes the activity enjoyable or meaningful (autonomy, mastery, purpose).
  2. Assess existing incentives
    Map any tangible or social rewards currently influencing behaviour. Determine whether they encourage compliance or curiosity.
  3. Apply selective reinforcement
    Use external rewards sparingly and strategically, ensuring they acknowledge intrinsic effort rather than replace it.
  4. Shift focus to autonomy
    Frame rewards as recognition of self-directed achievement, not as control levers.
  5. Audit impact over time
    Revisit performance and engagement metrics after reward adjustments to detect any drop in intrinsic motivation.

Tips

  • Use verbal or symbolic recognition (“thank you,” badges, public appreciation) rather than contingent financial incentives.
  • Offer choice and ownership — allow participants to decide how they achieve a goal to preserve autonomy.
  • Emphasise progress over outcome to reinforce intrinsic mastery.

Pitfalls

Over-rewarding early enthusiasm

Keep initial rewards symbolic or unexpected to preserve intrinsic interest.

Reward dependency

Rotate or fade rewards to prevent conditioning behaviour to external triggers.

Misaligned KPIs

Avoid metrics that drive superficial performance at the expense of genuine learning or creativity.

Acceptance criteria

  • Participants express sustained interest in the activity independent of reward presence.
  • Engagement metrics (quality, initiative, creative output) remain stable or improve after reward reduction.
  • Reflections or surveys indicate alignment between personal satisfaction and performance outcomes.

Tutorial

Scenario

  • A product design team at a tech startup introduces a “Feature of the Month” bonus to accelerate innovation.
  • Initially, designers are excited—but soon creativity stalls.
  • The team starts focusing on “what might win the bonus” rather than on solving meaningful user problems.
  • Leadership suspects reward undermining might be at play.

Input/Output
Actions
Error handling
Closure

Should management maintain, modify, or remove the external bonus system to restore authentic creativity?

Input
Data on feature submissions, team morale, and idea quality pre- and post-bonus.

Output
Revised incentive framework that sustains creativity without dependence on cash rewards.

  1. Conduct a motivation audit — interview designers to uncover intrinsic drivers (autonomy, challenge, recognition).
  2. Reframe rewards from performance-based to learning-based — e.g., recognise “most insightful experiment” rather than “most shipped feature.”
  3. Replace cash bonuses with symbolic recognition, such as internal showcases or spotlight features in the company newsletter.
  4. Facilitate peer appreciation sessions where team members celebrate each other’s creative approaches.
  5. Monitor engagement indicators (idea volume, diversity, enthusiasm) to validate that intrinsic motivation rebounds.

If motivation still dips, adjust by reintroducing optional incentives tied to team learning outcomes rather than individual competition. This preserves cooperation while satisfying recognition needs.

The design team reports a renewed sense of creative freedom and experimentation. By reframing rewards around intrinsic values, leadership realigns the culture toward mastery and shared purpose rather than token gain.

Result

Before
Short-term bursts of output followed by fatigue and strategic shallowness.

After
Sustained creative momentum, stronger peer trust, and alignment with user-centred goals.

Variations

  • In education, replace grades with progress portfolios to encourage intrinsic curiosity.
  • In customer loyalty, use unexpected “thank-you” gestures instead of predictable discounts.
  • In software gamification, prioritise progress feedback over points or badges to maintain engagement authenticity.
