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...

Researchers across academic disciplines have applied Instructional Manipulation Checks (IMCs) to detect inattentive survey participants (Anduiza & Galais, 2017; Motta, Callaghan, & Smith, 2016; Oppenheimer, Meyvis, & Davidenko, 2009; Paas & Morren, 2018; Peer, Brandimarte, Samat, & Acquisti, 2017; Persson &...

A shift to more sustainable diets is needed to ensure food security and to reduce the pressure on the environment. Yet, many consumers have misconceptions about the environmental impacts of their diets and lack knowledge on how to prepare sustainable meals. This study uses a mixed-methods...

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)....
