4. A Little Psychology
Scientific study of behavior
People act for reasons
Successful behavior change strategies
require an understanding of the individual
and situational factors that motivate and/or
constrain behavior
Many examples of failed (or not tested)
and even boomerang effects
5. Tools for Promoting Water
Conservation
1. Education
Involves disseminating information
Assumes that lack of behavior results
from lack of knowledge
(this is generally not true)
Consistently across behavioral domains,
research has shown small-to-null effects
9. Tools for Promoting Water
Conservation
2. Price
Cost directly affects behavior
Problems with price triggers:
Specificity (no spillover)—think incentives for
low-flow toilets
Framing (conservation now framed as
“transaction”)
Can potentially undermine long-term
changes (Cialdini’s fence)
10. Tools for Promoting Water
Conservation
3. Awareness
Crisis can induce change
Individuals rally around a cause (for a
short period of time)
Crisis messages can boomerang if used
for too long
And what happens when the crisis
passes?
12. Social Norms
A promising alternative
Conservation often means deviating from
the norm (this message will boomerang)
Need to promote community support:
Your neighbors are conserving
People will disapprove if you don’t conserve
How much you consume relative to others
14. Can we reduce consumption?
Yes, but new tools will be required
Price-triggers can work (but come with side
effects)
Information generally won’t work
Awareness and crisis will work for a short
period
Fostering social norms provides a
promising alternative

Notas del editor
Conservation means people doing something. It means behavior.
Common view of psychologists as clinicians with couches. While this was partially true 50 years ago, it’s not true today.
Modern psychology is the scientific study of behavior, and applied psychologists (like me) use psychological principles to solve social problems.
Behavior is not mysterious. People act (or don’t act) for reasons. While these reasons might not be readily apparent (even to the person doing the action), there are nevertheless specific reasons for behavior. These reasons are knowable, and can be targeted with interventions.
In the last 100 years, psychologists have amassed a tremendous volume of knowledge about human behavior. Unfortunately, these theories and principles are rarely applied to social problems. (Advertising products is a notable exception, but this knowledge is not publicly available)
