How Warm Days Increase Belief in Global Warming

by Lisa Zaval, Elizabeth A. Keenan, Eric J. Johnson and Elke U. Weber

Abstract

Climate change judgments can depend on whether today seems warmer or colder than usual, termed the local warming effect. Although previous research has demonstrated that this effect occurs, studies have yet to explain why or how temperature abnormalities influence global warming attitudes. A better understanding of the underlying psychology of this effect can help explain the public's reaction to climate change and inform approaches used to communicate the phenomenon. Across five studies, we find evidence of attribute substitution, whereby individuals use less relevant but available information (for example, today's temperature) in place of more diagnostic but less accessible information (for example, global climate change patterns) when making judgments. Moreover, we rule out alternative hypotheses involving climate change labelling and lay mental models. Ultimately, we show that present temperature abnormalities are given undue weight and lead to an overestimation of the frequency of similar past events, thereby increasing belief in and concern for global warming.

Adeo Health Science: Turning a Product into a Brand

Elizabeth A. Keenan and Jill Avery

For decades, American parents were warned to avoid introducing potential allergens to their babies prior to their first birthday. But two influential clinical studies caused the medical establishment to radically reverse its position. Parents were now warned that delaying the introduction of these types of foods increased a baby's risk of food allergies. Adeo Health Science was ready, with patents filed for a baby food that made it simple for parents to introduce allergens. Now, the new company had to turn its product into a brand and map its go-to-market strategy, including creating a compelling value proposition, choosing a path to market that was either direct-to-consumer, through grocery retailers, or via the physician channel, and planning its marketing communications and sales strategy. As a new startup with constrained resources, the company knew its marketing decisions would make or break the new product.

Back to the Roots is a startup with a social mission to “undo food”—to reconnect people to where their food comes from. In late 2017, they are contemplating their next move. Back to the Roots has an eclectic portfolio of products, including ready-to-grow (e.g., gardens in a can) and ready-to-eat (e.g., cereal) products, and they are being courted by two major players in each category. With an award-winning snack bar in their hands, they are now debating whether they should delve further in to the ready-to-eat category. It is a competitive space and they wonder if they are ready to launch yet another new product and, if so, what this move would mean for their ready-to-grow product line.

Pseudo-set framing—arbitrarily grouping items or tasks together as part of an apparent “set”—motivates people to reach perceived completion points. Pseudo-set framing changes gambling choices (Study 1), effort (Studies 2 and 3), giving behavior (Field Data and Study 4), and purchase decisions (Study 5). These effects persist in the absence of any reward, when a cost must be incurred, and after participants are explicitly informed of the arbitrariness of the set. Drawing on Gestalt psychology, we develop a conceptual account that predicts what will—and will not—act as a pseudo-set and defines the psychological process through which these pseudo-sets affect behavior, concluding that over and above typical reference points, pseudo-set framing alters perceptions of (in)completeness, making intermediate progress seem less complete. In turn, these feelings of incompleteness motivate people to persist until the pseudo-set has been fulfilled.
