Lecture Notes: Understanding and Making Effective Change

Introduction

• Challenge the Known: The greatest adversary to change is common sense; not the difficulty of change itself.
• Example: Littering reduction campaigns illustrate how common sense can mislead.

Common Sense Misleading

1. Information Alone is Insufficient

• Misconception: Educating people is enough to change behavior.
• Energy Conservation Study:
  • Auditors identified home energy inefficiencies (e.g., cracks around doors/windows).
  • Result: Only 20% acted on this information.
• Solution:
  • Make information tangible (e.g., comparing total air leaks to size of a basketball).
  • Personalize and interact socially.
  • Outcome: 60% compliance when information is made tangible and personalized.

2. Loss Aversion

• Behavioral Insight: People hate losing more than they appreciate gains.
• Example: Denver Water Campaign emphasizes water loss to motivate conservation.

3. Audience-Specific Messaging

• High-Risk Alcohol Use Campaign:
  • Heavy drinkers focus on peer behaviors.
  • Lighter drinkers focus on broader student behaviors.
• Strategy: Tailor the message to the audience for effectiveness.

Attitudes vs. Behavior

• Misconception: Changing attitudes will change behavior.
• Reality: Attitudes follow behavior, not the other way around.
• Action: Set behavioral expectations without changing attitudes (e.g., turning off lights).

Underlying Values

• Building Green Buildings:
  • Environmentalists value resource saving.
  • Frugal individuals value eliminating waste.
• Strategy: Unite different values under conservation to gain broad support.

Motivation Misunderstood

• Social Norms: Powerful but underestimated motivators.
  • Example: Hotel towel reuse driven by social norms over environmental messages.
• Street Musicians: Demonstrate the effect of social norms (e.g., visible tipping).

Campaign Effectiveness

• Case Study: Littering Campaign
  • Poster A: Shows magnitude of the problem.
  • Poster B: Models positive behavior using social norms.
  • Outcome: Poster B more effective due to use of social norms.

Conclusion

• Effective Change: Requires rethinking beyond common sense and utilizing social science insights.
• Final Note: Social science offers "magic" for effective change by understanding human behavior.
