Net zero: the role of consumer behaviour


Horizon Scan by the UK Parliament: “According to research from the Centre for Climate Change and Social Transformation, reaching net zero by 2050 will require individual behaviour change, particularly when it comes to aviation, diet and energy use.

The government’s 2023 Powering Up Britain: Net Zero Growth Plan referred to low carbon choices as ‘green choices’, and described them as public and businesses choosing green products, services, and goods. The plan sets out six principles regarding policies to facilitate green choices. Both the Climate Change Committee and the House of Lords Environment and Climate Change Committee have recommended that government strategies should incorporate greater societal and behavioural change policies and guidance.

Contributors to the horizon scan identified managing consumer behaviour and habits to help achieve net zero as a topic of importance for parliament over the next five years. Change in consumer behaviour could result in approximately 60% of required emission reductions to reach net zero.[5] Behaviour change will be needed from the wealthiest in society, who according to Oxfam typically lead higher-carbon lifestyles.

Incorporating behavioural science principles into policy levers is a well-established method of encouraging desired behaviours. Common examples of policies aiming to influence behaviour include subsidies, regulation and information campaigns (see below).

However, others suggest deliberative public engagement approaches, such as the UK Climate Change Assembly,[7] may be needed to determine which pro-environmental policies are acceptable.[8] Repeated public engagement is seen as key to achieve a just transition as different groups will need different support to enable their green choices (PN 706).

Researchers debate the extent to which individuals should be responsible for making green choices as opposed to the regulatory and physical environment facilitating them, or whether markets, businesses and governments should be the main actors responsible for driving action. They highlight the need for different actions based on the context and the different ways individuals act as consumers, citizens, and within organisations and groups. Health, time, comfort and status can strongly influence individual decisions while finance and regulation are typically stronger motivations for organisations (PN 714)…(More)”

Boosting: Empowering Citizens with Behavioral Science


Paper by Stefan M. Herzog and Ralph Hertwig: “…Behavioral public policy came to the fore with the introduction of nudging, which aims to steer behavior while maintaining freedom of choice. Responding to critiques of nudging (e.g., that it does not promote agency and relies on benevolent choice architects), other behavioral policy approaches focus on empowering citizens. Here we review boosting, a behavioral policy approach that aims to foster people’s agency, self-control, and ability to make informed decisions. It is grounded in evidence from behavioral science showing that human decision making is not as notoriously flawed as the nudging approach assumes. We argue that addressing the challenges of our time—such as climate change, pandemics, and the threats to liberal democracies and human autonomy posed by digital technologies and choice architectures—calls for fostering capable and engaged citizens as a first line of response to complement slower, systemic approaches…(More)”.

Changing Behaviour by Adding an Option


Paper by Lukas Fuchs: “Adding an option is a neglected mechanism for bringing about behavioural change. This mechanism is distinct from nudges, which are changes in the choice architecture, and instead makes it possible to pursue republican paternalism, a unique form of paternalism in which choices are changed by expanding people’s set of options. I argue that this is truly a form of paternalism (albeit a relatively soft one) and illustrate some of its manifestations in public policy, specifically public options and market creation. Furthermore, I compare it with libertarian paternalism on several dimensions, namely respect for individuals’ agency, effectiveness, and efficiency. Finally, I consider whether policymakers have the necessary knowledge to successfully change behaviour by adding options. Given that adding an option has key advantages over nudges in most if not all of these dimensions, it should be considered indispensable in the behavioural policymaker’s toolbox…(More)”.

Determinants of behaviour and their efficacy as targets of behavioural change interventions


Paper by Dolores Albarracín, Bita Fayaz-Farkhad & Javier A. Granados Samayoa: “Unprecedented social, environmental, political and economic challenges — such as pandemics and epidemics, environmental degradation and community violence — require taking stock of how to promote behaviours that benefit individuals and society at large. In this Review, we synthesize multidisciplinary meta-analyses of the individual and social-structural determinants of behaviour (for example, beliefs and norms, respectively) and the efficacy of behavioural change interventions that target them. We find that, across domains, interventions designed to change individual determinants can be ordered by increasing impact as those targeting knowledge, general skills, general attitudes, beliefs, emotions, behavioural skills, behavioural attitudes and habits. Interventions designed to change social-structural determinants can be ordered by increasing impact as legal and administrative sanctions; programmes that increase institutional trustworthiness; interventions to change injunctive norms; monitors and reminders; descriptive norm interventions; material incentives; social support provision; and policies that increase access to a particular behaviour. We find similar patterns for health and environmental behavioural change specifically. Thus, policymakers should focus on interventions that enable individuals to circumvent obstacles to enacting desirable behaviours rather than targeting salient but ineffective determinants of behaviour such as knowledge and beliefs…(More)”

Behavioural science: could supermarket loyalty cards nudge us to make healthier choices?


Article by Magda Osman: “Ken Murphy, CEO of the British multinational supermarket chain Tesco, recently said at a conference that Tesco “could use Clubcard data to nudge customers towards healthier choices”.

So how would this work, and do we want it? Our recent study, published in the Scientific Journal of Research and Reviews, provides an answer.

Loyalty schemes have been around as far back as the 1980s, with the introduction of airlines’ frequent flyer programmes.

Advancements in loyalty schemes have been huge, with some even using gamified approaches, such as leaderboards, trophies and treasure hunts, to keep us engaged. The loyalty principle relies on a form of social exchange, namely reciprocity.

The ongoing reciprocal relationship means that we use a good or service regularly because we trust the service provider, we are satisfied with the service, and we deem the rewards we get as reasonable – be they discounts, vouchers or gifts.

In exchange, we accept that, in many cases, loyalty schemes collect data on us. Our purchasing history, often tied to our demographics, generates improvements in the delivery of the service.

If we accept this, then we continue to benefit from reward schemes, such as promotional offers or other discounts. The effectiveness depends not only on making attractive offers to us for things we are interested in purchasing, but also other discounted items that we hadn’t considered buying…(More)”

The Unaccountability Machine — why do big systems make bad decisions?


FT Review of book by Dan Davies: “The starting point of Davies’ entertaining, insightful book is that the uncontrolled proliferation of accountability sinks is one of the central drivers of what historian Adam Tooze calls the “polycrisis” of the 21st century. Their influence reaches far beyond frustrated customers endlessly on hold to “computer says no” service departments. In finance, banking crises regularly recur — yet few individual bankers are found at fault. If politicians’ promises flop, they complain they have no power; the Deep State is somehow to blame.

The origin of the problem, Davies argues, is the managerial revolution that began after the second world war, abetted by the advent of cheap computing power and the diffusion of algorithmic decision-making into every sphere of life. These systems have ended up “acting like a car’s crumple-zone to shield any individual manager from a disastrous decision”, he writes. While attractive from the individual’s perspective, they scramble the feedback on which society as a whole depends.

Yet the story, Davies continues, is not so simple. Seen from another perspective, accountability sinks are entirely reasonable responses to the ever-increasing complexity of modern economies. Standardisation and explicit policies and procedures offer the only feasible route to meritocratic recruitment, consistent service and efficient work. Relying on the personal discretion of middle managers would simply result in a different kind of mess…(More)”.

Second-Order Agency


Paper by Cass Sunstein: “Many people prize agency; they want to make their own choices. Many people also prize second-order agency, by which they decide whether and when to exercise first-order agency. First-order agency can be an extraordinary benefit or an immense burden. When it is an extraordinary benefit, people might reject any kind of interference, or might welcome a nudge, or might seek some kind of boost, designed to increase their capacities. When first-order agency is an immense burden, people might also welcome a nudge or might make some kind of delegation (say, to an employer, a doctor, an algorithm, or a regulator). These points suggests that the line between active choosing and paternalism can be illusory. When private or public institutions override people’s desire not to exercise first-order agency, and thus reject people’s exercise of second-order agency, they are behaving paternalistically, through a form of choice-requiring paternalism. Choice-requiring paternalism may compromise second-order agency. It might not be very nice to do that…(More)”.

It’s time we put agency into Behavioural Public Policy


Article by Sanchayan Banerjee et al: “Promoting agency – people’s ability to form intentions and to act on them freely – must become a primary objective for Behavioural Public Policy (BPP). Contemporary BPPs do not directly pursue this objective, which is problematic for many reasons. From an ethical perspective, goals like personal autonomy and individual freedom cannot be realised without nurturing citizens’ agency. From an efficacy standpoint, BPPs that override agency – for example, by activating automatic psychological processes – leave citizens ‘in the dark’, incapable of internalising and owning the process of behaviour change. This may contribute to non-persistent treatment effects, compensatory negative spillovers or psychological reactance and backfiring effects. In this paper, we argue agency-enhancing BPPs can alleviate these ethical and efficacy limitations to longer-lasting and meaningful behaviour change. We set out philosophical arguments to help us understand and conceptualise agency. Then, we review three alternative agency-enhancing behavioural frameworks: (1) boosts to enhance people’s competences to make better decisions; (2) debiasing to encourage people to reduce the tendency for automatic, impulsive responses; and (3) nudge+ to enable citizens to think alongside nudges and evaluate them transparently. Using a multi-dimensional framework, we highlight differences in their workings, which offer comparative insights and complementarities in their use. We discuss limitations of agency-enhancing BPPs and map out future research directions…(More)”.

Fixing frictions: ‘sludge audits’ around the world


OECD Report: “Governments worldwide are increasingly adopting behavioural science methodologies to address “sludge” – the unjustified frictions impeding people’ access to government services and exacerbating psychological burdens. Sludge audits, grounded in behavioural science, provide a structured approach for identifying, quantifying, and preventing sludge in public services and government processes. This document delineates Good Practice Principles, derived from ten case studies conducted during the International Sludge Academy, aimed at promoting the integration of sludge audit methodologies into public governance and service design. By enhancing government efficiency and bolstering public trust in government, these principles contribute to the broader agenda on administrative simplification, digital services, and public sector innovation…(More)”.
