Nudges have been increasingly deployed to deliver climate policies in the last decade. Recent evidence shows nudges are hard to scale–up. So can we use nudges more effectively, or should we rely on other tools of behaviour change? We argue that reflective strategies can enhance nudges by...

Nudging people towards sustainable diets can help mitigate agricultural emissions. Recent debate suggests “nudges” can have heterogeneous treatment effects in the population, including some backfire effects. So, can we identify this heterogeneity and design more effective nudges for...

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 pursue this objective, which is problematic for many reasons. From an ethical perspective, goals like personal...

This paper is comprehensive review of the research agenda around nudge+. It reviews the nudge+ tool, first by explaining why a deliberative or thinking element is needed at the present time, where nudge+ comes from intellectually in the history of think and deliberative interventions and...

Nudging has been used to make public policies widely, in various fields such as personal finance, health, education, environment/climate, privacy, law, and human well-being. Nonetheless, with an increase in the applications of nudging, the toolkit of nudges also expanded massively, which...

Taxing meat optimally is a first-best policy outcome to internalize environmental harms. However, meat taxes often lack public and governmental support. Recent research indicates that support for meat taxes can be improved by combining behavioral nudges with fiscal measures. In this study, we...

Using a nationally representative sample of 1052 respondents from the United Kingdom, we systematically tested the associations between the experimental trust game and a range of popular self-reported measures for trust, such as the General Social Survey (GSS) and the Rosenberg scale for...

Adopting low-carbon diets is important to meet our climate goals. Prior experimental evidence suggests green nudges help people adopt such diets, more so when they are encouraged to think through them. In this paper, we re-evaluate this role of reflection in a “social norm" nudge to promote...

Short Abstract: We can scale up behaviour change by accounting for nuanced social complexities in which human responses to behavioural public policies are situated. We introduce the “social brain”, encompassing complex human relationships interacted with elements of choice architecture. It...

Previous studies have shown that our past pro-social actions influence our future ones. So, which pro-social deeds inspire us to do more? Can nudges promoting these deeds crowd out this behavioural spillover? We study a social norm nudge promoting vegetarianism in an online experiment (n=2775)....
