Habits to Save our Habitat: Using the Psychology of Habits to Promote Sustainability

Abstract

Recent dramatic shifts in pro-environmental attitudes have not been accompanied by similar increases in sustainable behavior. We propose that this attitude-behavior gap is partly driven by unsustainable habits. Policies can reduce this gap by enacting structural changes based on insights from habit psychology and behavioral economics. We outline three behavior change principles: First, policies can leverage friction to encourage repetition of sustainable actions and impede unsustainable ones. Second, policies can set up action cues for sustainable actions and disrupt existing cues for unsustainable habits. Finally, policies can encourage sustainable habits by using psychologically-informed incentives. We then describe how even initially-unpopular policies can become acceptable through habitual repetition. Habit psychology represents a promising but currently unrealized part of the policymaker's toolbox.

Using Virtual Reality to Stimulate Healthy and Environmentally Friendly Food Consumption among Children: An Interview Study

“…Once formed, habits can be strong and difficult to alter, which is illustrated by the findings from a study on meat consumption; meat eating habits were found to have the strongest positive influence on meat consumption, much stronger than the also significant, negative influence of reduction intentions [14]. Given their strong influence on behaviour, the formation of healthy and environmentally friendly habits is key in achieving and maintaining healthy and environmentally friendly behaviour-something that was, with regard to sustainability, also recently suggested by others [15]-and should be done as early in life as possible.…”

Stuck on Intergroup Attitudes: The Need to Shift Gears to Change Intergroup Behaviors

“…Sidelining bias capitalizes on situationism (i.e., the powerful influence of small environmental changes on behavior; Ross & Nisbett, 2011). My proposal also builds on efforts by researchers in other areas, such as vaccination promotion and climate change, who have advocated for an increased focus on the social and psychological factors that affect behavior and behavior change (Brewer et al, 2017;Mazar et al, 2021).…”

“… 23 24 25 26 They can be described as structural, designed to create environments that readily enable sustainable behaviours and make unsustainable behaviours more difficult. 27 These interventions also place lower demands on the cognitive, social, and material resources of individuals than those based on providing advice and guidance, thereby having greater potential to achieve change equitably. 28 29 For example, increasing the proportion of vegetarian meal choices in UK cafeterias from one in four to two in four increased their selection from 24% to 39%.…”
