We often hear the argument that, given the urgency of climate change and sustainability concerns, significant changes to individual behaviours and lifestyles are required. This has led to a wide array of public education and climate literacy campaigns aimed at changing such behaviours. In this blog, I will argue that some fairly strong research findings suggest that such campaigns are of limited value in influencing behaviour change, and moreover that focusing on changes in individual behaviours may be distracting us from much more significant possible steps.
There are many models of behaviour change in the literature, and of the relationships among values, attitudes, intentions and behaviours. It is probably fair to say that many of the most influential conceptualizations of behaviour change assume that most individual behaviours are the result of some form of conscious decision-making about desirable outcomes based in turn on some assessment of the consequences of different courses of action. 
On this view, people act in environmentally irresponsible ways because they lack the information they need to make better decisions. Such an ‘information deficit’ model leads in turn to what we might call a persuasive communication approach to stimulating behavior change, which assumes that providing more information as to those consequences, through information provision, educational programs, and science and climate change literacy campaigns, will lead to better and more environmentally responsible decision-making .
Unfortunately, the relevant research on the relationship between information and behaviour shows that persuasive communication approaches based on an information deficit model are not only ineffective in changing behaviours in the desired direction , but may in fact have perverse consequences.
Studies of the relationship between knowledge and attitudes have found that increased science literacy does not lead people to become more concerned about climate change, but on the contrary, actually increases polarization on this issue. It seems that educating people on the science of climate change, or other sustainability problems, will not lead them to change their views on the problem itself, but instead may further reinforce their prior position.
In fact there is evidence from many fields of study, going back multiple decades, that information is only weakly connected to behaviour change. Studies of the effectiveness of energy efficiency programs , research in health promotion, or community-based social marketing, over many decades have all reached similar findings. So widespread are these findings that it can be said, in the words of my colleague David Maggs that:
The best evidence that information does not change behaviour is that we have decades of evidence in multiple fields that it does not do so, yet we continue to create and implement pubic education campaigns intended to change individual behaviour.
While this is bad enough, the problem gets worse.
It turns out that it is not clear that changing individual consumption behaviour is the right goal anyway. A number of studies have shown that there is no significant difference in either the carbon or ecological footprint of individual who cares deeply about environmental issues and behave accordingly, and those who do not care at all and do not behave in environmentally responsible ways . The reason is that the ecological and carbon footprints of individuals are determined much more by their income than by the degree to which they choose more environmentally appropriate behaviours such as recycling or buying sustainable products.
So we seem to be in a depressing circumstance: information and literacy programs won’t change behaviour; moreover, it wouldn’t much matter, in term of overall environmental impact, if they did.
But rather than ignoring this evidence and intensifying our efforts to educate people into sustainability, or else throwing up our hands and retreating into apathy, perhaps a more fruitful approach is to reframe the original questions and ask whether a different approach altogether might be useful, on both these questions.
With regard to information provision, instead of a persuasive communication approach, it might be more useful to take what we might call an emergent dialogue approach . Instead of assuming that we know the right answers and we have to get those answers into the heads of our audience, perhaps we need to listen as much as we speak, and to find two-way approaches to dialogue in order to co-create narratives with citizens that describe our circumstances in ways that are more faithful to the disparate views and values of different groups and that thereby offer the possibility of finding common ground on controversial societal problems.
The goal switches from a focus on changing behaviours to a focus on trying to create shared narratives, in order to better inform collective decision-making processes, and to foster social mobilization in support of policy change.
With regard to individual behaviour change, perhaps we need to rethink our ideas about change itself. As long as sustainability requires change, then it is fragile because human activities and practices will often snap back to prior unsustainable normals. Instead, we need to normalize sustainable practices, so that they become the default, not the required change . In this connection, it might be useful to move from a focus on conscious individual behaviour and pay more attention to more collective processes of activity. There has been an upsurge of work on social practice theory approaches to human activity, which suggests that much of that activity is unconscious and collective, connected to social processes and relationships, and social and cultural norms . Can a focus on collective social practices lead us towards processes of normalization of sustainability?
Following this line of thought, it is not about encouraging behaviour change instead of technological change, but of exploring how the overall socio-technical system itself, including powerful social norms, influences and is influenced by individual choices and actions, including political demands or support for changes in collective decisions. Perhaps we need to try to create ‘virtuous cascades’ 12 of positive normative change and identify leverage points that will allow us to foster and encourage more sustainable outcomes. Trying to convince people to change their lifestyles in the absence of change in the overall system will be ineffective and may even work against larger system change.
