Underlying Assumptions 1. Technology & new media are changing how people
interact with our natural, built, and social worlds.

Underlying Assumptions 1. Technology & new media are changing how people
interact with our natural, built, and social worlds.
2. There are potential opportunities to leverage these changes for pro-social / pro-environmental benefit.

Underlying Assumptions 1. Technology & new media are changing how people
interact with our natural, built, and social worlds.
2. There are potential opportunities to leverage these changes for pro-social / pro-environmental benefit.
3. Psychology provides a rich history and theoretical base with which to understand this potential.

What is Feedback? “Information about the result of a process or action that can be used in modification or control of a process or system”
Oxford English Dictionary

The “Behavioral Wedge” � “Unlocking Energy Efficiency in the US Economy”
� $1 trillion � 20 gigatons of greenhouse gas
“…but only if the nation can craft a comprehensive and innovative approach to unlock it.” (McKinsey & Company, 2009)
� “Household actions can provide a behavioral wedge to rapidly reduce carbon emissions” � 5-12% reduction in 5 years � 9-22% reduction in 10 years “…without waiting for new technologies or regulations or changing
household lifestyle.” (Dietz, Gardner, Gilligan, Stern, & Vandenbergh, 2009)

Looking at past research � 100+ studies conducted since 1976 � Effect sizes ranged from -.0830 to .4803 � Mean r-effect size = .1174 (p < .001)
� Moderating variables: � duration (longer = more effective) � Frequency (more frequent = more effective) � Medium (computer/device > paper)

Limitations of Studies
� Not naturalistic � Participants recruited to participate � May be different from “active adopters”
� Not comparative � Most studies tests one type of feedback (vs. control) � Very few commercial products in studies
� Not testing mediation � DV is energy use, but studies rarely test possible
mediators to explain effectiveness

Present research
1. Identify ‘naturalistic’ users of feedback � Who is really using these products? � Purposive sampling
2. Ask about the user experience � Enables comparisons between devices � Gain insights into usability, adoption, etc.
3. Explore perceptions and barriers � Understand market beyond the “early adopters” � Identify potential barrier and leverage points

Diffusion of Innovation Theory of technology adoption which explains:
1. Social process by which an innovation spreads throughout a population
2. Personal process by which individuals decide to adopt an innovation

Findings � Social Diffusion (family/friends/colleagues)
� 20% learned about product through friend/family

� Utility acquisition (21%)
� Borrowing (13%)

I’m too busy to worry about my energy consumption
they might not be available in my area

“To induce behavior these devices have to be free or very low cost.”
“I often recommend it, but have a hard time convincing others that it is worth the [money]”

Confirmation
Usability � What do you like / dislike about the product? � What was your most surprising experience?
Outcomes � Did knowledge, behavior, and/or energy use change? � Do you still use this product?
Karlin 2012
![Page 37: Diffusion of Feedback: Perceptions and Adoption of Devices](https://reader034.vdocument.in/reader034/viewer/2022042818/55c04bb7bb61eb181e8b4584/html5/thumbnails/37.jpg)
Confirmation – positive
Usability � Ease of use � Effective energy information
Outcomes � Correct inaccurate assumptions about energy use � Both general and specific behavior change reported
Karlin, 2012
I had no idea how much energy computers used
We installed power strips to easily power off all high energy items
![Page 38: Diffusion of Feedback: Perceptions and Adoption of Devices](https://reader034.vdocument.in/reader034/viewer/2022042818/55c04bb7bb61eb181e8b4584/html5/thumbnails/38.jpg)
Confirmation - negative
“Rebound Effect” � 15% were surprised that they used less energy than they thought
Diminishing utility � 48% said they do not still use the product
� No longer in possession/borrowed � Do not see a need to continue using
“…I’ve actually wound up using more energy on some devices when I see how little energy they use (my laptop, for one).”
“it’s served it’s purpose”
“I checked almost every device I have, so continued usage isn't very informative unless I start tracking usage in a spreadsheet - way too much work.”
Karlin, 2012
![Page 39: Diffusion of Feedback: Perceptions and Adoption of Devices](https://reader034.vdocument.in/reader034/viewer/2022042818/55c04bb7bb61eb181e8b4584/html5/thumbnails/39.jpg)
Implications
1. Further research into active feedback adopters could yield positive results for segmentation.
2. Research into leveraging social networks to promote the use of feedback devices is promising.
3. There is promise for utility-based and lending/borrowing programs for distribution.
4. Integrating injunctive social norms (e.g. social comparison) could address rebound effect.
5. Further research is needed into actual and perceived barriers of potential users.
