1. Why don’t Americans conserve energy and adopt energy-efficient technologies?

2. Don’t know how much I will save
On why people do not act
Information deficit
model
Motivation deficit
model
Don’t know how much I will save
Don’t know what to do
Don’t know how …
Cost
Time
Effort
Social norms …

3. Behaviors deemed “most effective” by participants
Curtailment
State what colors mean, state some behaviors are wacky. Efficiency is defined as switching to a technology without sacrificing desired services, curtailment is defined as cutting back on normal or desired activities--- the whole presentation of curtailment is verbal, need a reference for who stated efficiency is better than curtailment?? State CURTAILMENT and EFFICIENCY
Efficiency

10. Findings: “In your opinion, what is the most effective thing that you could do to conserve energy in your life?”
- Participants state:
55% “curtailment”
12% “efficiency”
Gardener and Stern (2008):
“efficiency saves more energy than curtailment”
Large overarching misperception

11. Findings: Major misperceptions in energy consumption
People have small overestimates for
low-energy behaviors and large underestimates for high-energy behaviors
 many implications for technology, education, and policy

12. What you want to do vs. What others should do

13. Research questions
Would there be any systematic differences in how people answer the following two questions?
“In your opinion, what is the single most effective thing that you could do to use less energy in your life?”
“In your opinion, what is the most single most effective thing that Americans could do to use less energy in their lives?”

14. Predictions If information deficits: If motivated cognition:
Distribution of responses should be similar for both questions
If motivated cognition:
Systematic differences in responses between questions (e.g., listing an easy non-effective behavior for self and a harder effective behavior for others)

15. Most effective behavior: Self vs. others

16. Most effective behavior: Self vs. others

17. Most effective action for self and other Americans
Cut thru the chase, BUILD UP and REMOVE OTHER, MAKE A 2x2
Turn off (appliances and lights) Drive less (drive less, carpool, use public transportation, bike, and walk)

18. I’ll do the easy thing, you do the hard thing
Individuals who choose the easier option for themselves are likely to ask others to do the harder thing. McNemar chi-square statistic for asymmetry 26.1, p <

19. Findings: I’ll do the easy thing, you do the hard thing
People are motivated to list easier non-effective behaviors for themselves (e.g., turning off the light) and harder more effective behaviors for others (e.g., carpooling, driving less).

20. Part II : Communicating climate change

22. Description-based decision Experience-based decision
Decide on taking a drug based on drug package insert information
Invest in a mutual fund based on the information in its prospectus
Decision to back up computer’s hard drive
Invest in a system to irrigate crops based on personal memory
When small-probability (rare) events are involved, people choose as if they over-weigh the probability of the rare event
(Kahnemann and Tversky, 1979)
People choose as if they under-weigh the probability of the rare event … unless the statistically rare event occurred in the very recent past (recency effect)
(Hertwig, Baron, Weber, Erev, 2004, 2006)
In description-based decisions: When small-probability (rare) events are involved, people choose as if they over-weigh the probability of the rare event
Mostly the case when rare event has emotional impact, e.g. side effect of vaccine on own child.
Physician vs. parent

23. Likelihood predictions based on availability and ease of recall

24. In your opinion, which is a more likely cause of death in the US:
Falling airplane parts
Sharks
In your opinion which, is the cause of death that is more common in the US:
Car accidents
Stomach cancer
In your opinion, which is the cause of death that is more common in the US:
Tornado
Lightning
Correct answer circled in red

25. Conclusions: How to Approach the Motivation Deficit
Risk communication CAN be improved
Keep multiple goals in mind, look for co-benefits
No “one-size-fits-all” approach
Combinations of affective/experience-based and analytic information
Participatory processes to tailor information
Group decision context primes collective interests
Awareness of need for individual actions also builds awareness of need for collective action
