Shifting consumer behavior to address climate change.

We review recent articles on how to change consumer behavior in ways that improve climate impacts, with a special focus on those articles using experimental interventions and measuring actual behaviors. We organize the findings using the SHIFT framework to categorize behavior change strategies based on five psychological factors: Social influence (e.g. communicating that others are changing to plant-based diets doubled meatless lunch orders), Habit (e.g. consumer collaboration to establish new, value-based practices helped to reduce food waste), Individual self (e.g. when women made up half of the group, 51% more trees were conserved), Feelings and cognition (e.g. anticipated guilt reduced choice of unethical attributes in made-to-order products), and Tangibility (e.g. concrete representations of the future of recycled products improved recycling behavior).

The Sign Effect in Past and Future Discounting.

We compared the extent to which people discounted positive and negative events in the future and in the past. We found that the tendency to discount gains more than losses (i.e., the sign effect) emerged more strongly for future than for past outcomes. We present evidence from six studies (total N = 1,077) that the effect of tense on discounting is tied to differences in the contemplation emotion of these events, which we assessed by measuring participants' emotions while they either anticipated or remembered the event. We ruled out loss aversion, uncertainty, utility curvature, thought frequency, and connection to the future and past self as explanations for this phenomenon, and we discuss why people experience a distinct mixture of emotions when contemplating upcoming events.

A typology of time-scale mismatches and behavioral interventions to diagnose and solve conservation problems.

Ecological systems often operate on time scales significantly longer or shorter than the time scales typical of human decision making, which causes substantial difficulty for conservation and management in socioecological systems. For example, invasive species may move faster than humans can diagnose problems and initiate solutions, and climate systems may exhibit long-term inertia and short-term fluctuations that obscure learning about the efficacy of management efforts in many ecological systems. We adopted a management-decision framework that distinguishes decision makers within public institutions from individual actors within the social system, calls attention to the ways socioecological systems respond to decision makers' actions, and notes institutional learning that accrues from observing these responses. We used this framework, along with insights from bedeviling conservation problems, to create a typology that identifies problematic time-scale mismatches occurring between individual decision makers in public institutions and between individual actors in the social or ecological system. We also considered solutions that involve modifying human perception and behavior at the individual level as a means of resolving these problematic mismatches. The potential solutions are derived from the behavioral economics and psychology literature on temporal challenges in decision making, such as the human tendency to discount future outcomes at irrationally high rates. These solutions range from framing environmental decisions to enhance the salience of long-term consequences, to using structured decision processes that make time scales of actions and consequences more explicit, to structural solutions aimed at altering the consequences of short-sighted behavior to make it less appealing. Additional application of these tools and long-term evaluation measures that assess not just behavioral changes but also associated changes in ecological systems are needed.

A dirty word or a dirty world?: Attribute framing, political affiliation, and query theory.

We explored the effect of attribute framing on choice, labeling charges for environmental costs as either an earmarked tax or an offset. Eight hundred ninety-eight Americans chose between otherwise identical products or services, where one option included a surcharge for emitted carbon dioxide. The cost framing changed preferences for self-identified Republicans and Independents, but did not affect Democrats' preferences. We explain this interaction by means of query theory and show that attribute framing can change the order in which internal queries supporting one or another option are posed. The effect of attribute labeling on query order is shown to depend on the representations of either taxes or offsets held by people with different political affiliations.

Discounting future green: money versus the environment.

In 3 studies, participants made choices between hypothetical financial, environmental, and health gains and losses that took effect either immediately or with a delay of 1 or 10 years. In all 3 domains, choices indicated that gains were discounted more than losses. There were no significant differences in the discounting of monetary and environmental outcomes, but health gains were discounted more and health losses were discounted less than gains or losses in the other 2 domains. Correlations between implicit discount rates for these different choices suggest that discount rates are influenced more by the valence of outcomes (gains vs. losses) than by domain (money, environment, or health). Overall, results indicate that when controlling as many factors as possible, at short to medium delays, environmental outcomes are discounted in a similar way to financial outcomes, which is good news for researchers and policy makers alike.

Diffusion of treatment research: does Open Access matter?

Advocates of the Open Access movement claim that removing access barriers will substantially increase the diffusion of academic research. If successful, this movement could play a role in efforts to increase utilization of psychotherapy research by mental health practitioners. In a pair of studies, mental health professionals were given either no citation, a normal citation, a linked citation, or a free access citation and were asked to find and read the cited article. After 1 week, participants read a vignette on the same topic as the article and gave recommendations for an intervention. In both studies, those given the free access citation were more likely to read the article, yet only in one study did free access increase the likelihood of making intervention recommendations consistent with the article.
