About This Project

Behavioural policy interventions (BPIs), designed to influence people's behaviour without introducing mandates, are being adopted in increasingly polarised environments worldwide. Even though BPIs are not polarising per se, political disagreements can emerge if they are discussed alongside political cues. Across different countries and samples, this project examines how different communication strategies affect support for BPIs, and the tendency to (mis)perceive polarisation in this domain.

What is the context of this research?

Insights from behavioural sciences have been increasingly used to inform policies in a variety of domains (e.g., health, finance). In practice, behavioural policy interventions (BPIs) commonly involve altering features of the physical or social environment to steer individuals towards desirable behaviours and outcomes, whilst maintaining their freedom of choice.

Even though political ideology is not predictive of support for BPIs, partisan nudge bias is a phenomenon where people approved of BPIs more when these were paired with political objectives or sponsors that matched people’s political affiliation. Thus, even though BPIs do not seem to be polarising per se, they can easily become an area of polarisation when political information is simultaneously available.

What is the significance of this project?

This project will help us understand how both laypeople's and policymakers’ evaluations of and predictions concerning behavioural policy interventions (BPIs) can be skewed by their own political preferences.

In addition to expanding previous work on partisan nudge bias to the context of Slovenia and the UK, this project will address three significant gaps in the literature. First, it will help clarify how BPIs should be introduced to and discussed with the public to prevent them from falling prey to politicisation. Second, it will outline the differences between actual and perceived polarisation in the domain of BPIs. Finally, it will address the question of whether policymakers are also likely to (mis)perceive polarisation in the domain of BPIs despite their expertise.

What are the goals of the project?

This project examines whether people display partisan nudge bias when evaluating behavioural policy interventions (BPIs) in two European countries (Slovenia and the UK) and whether its magnitude depends on how BPIs are communicated - in a politically neutral way or alongside different political information.

In addition to examining people's own evaluation of BPIs, this project investigates whether people expect members of other political groups in society to show partisan nudge bias when evaluating BPIs (perceived partisan nudge bias), which will help us understand how perceived political animosity might lead to perceptions of disagreement in a novel domain. In total, this project involves two pilot (N = 50, completed) and two main studies (N = 500). More details can be found here.

Prizes for participants:

Since this is an independent project conducted by a group of undergraduate, master’s, and PhD students as a part of the Junior Researcher Programme, it is not externally funded. Thus, the research team decided to use Experiment to raise funds in order to be able to offer participants small prizes as a “thank you” for their participation. In each of the two countries (Slovenia and the UK), upon completing our ten-minute survey, participants will be entered into a prize draw for one of multiple $20 prizes.

Platform fee:

Experiment charges an 8% platform fee plus a 3-5% payment processing fee (please see the researcher guide).

Endorsed by

This project touches on a extremely valuable topic at a critical moment for societies around the world. By involving early career researchers, students, and young professionals, it doubles as an opportunity to build meaningful opportunities for the next generation of social scientists. Any support they receive will be put to immediate, meaningful use.

Team Bio

Our team consists of seven students from six countries who are a part of the Junior Researcher Programme. As a team, we care deeply about research that not only advances psychological science but also yields insights that could be helpful to practitioners and policymakers. We value transparency, openness, and reproducibility and these values guide every step of our research. Finally, we strive to create a friendly environment for learning and growth where all perspectives are welcome.


Jelka Stojanov

Jelka received her BA in Psychology from the University of Belgrade (Serbia) and is currently completing a DPhil (PhD) in Experimental Psychology at the University of Oxford (UK). Her PhD research aims to understand the role of emotions in the context of intergroup relations and conflict, with a particular focus on empathy. Beyond her doctoral work, Jelka has worked in the non-governmental sector in Serbia and is a co-founder of the FutureGov Fellowship, a four-month development programme offering aspiring policy practitioners a pathway into the field of public sector innovation.

Mathias Houe Andersen

Mathias is a final-year undergraduate student in Psychology at Aarhus University (Denmark). Beyond his coursework, Mathias is instructing different courses spanning social, personality, cognitive and developmental psychology. Finally, he has an immense interest in cognitive research paradigms and data analysis which has motivated him to actively pursue and embrace opportunities to get involved in various research projects.

Žiga Mekiš Recek

Žiga is a final-year undergraduate student in Psychology at the University of Ljubljana (Slovenia). His academic interests lie primarily in the fields of cognitive and social psychology. Additionally, his curiosity about psychological research methods has encouraged him to take up the position of research methods TA at his department. Furthermore, Žiga's interests have led him to get involved in research projects focusing on decision-making and applications of psychological insights to policymaking.

Ali Hajian

Ali is a third-year undergraduate student in Psychology at the University of Tehran (Iran). Mainly interested in social psychology and having previously worked in several non-governmental organisations in Iran, he hopes to learn more about how behavioural insights can facilitate the way people come together and collaborate. As such collaborations are heavily mediated by various social factors such as identity, meta-beliefs, and the level of intra- and intercultural differences, Ali believes social psychology will continue to shape effective policymaking in the future. Finally, he also has an interest in individual-level psychology, primarily personality, clinical, and cognitive psychology.

Alexandra Symeonidou

Alexandra received her BSc in Psychology from the National and Kapodistrian University of Athens (Greece) and is currently an MSc student in Clinical Psychology at Leiden University (Netherlands). Her academic interests lie in the fields of clinical and counselling psychology alongside social, political, and community psychology. Beyond her coursework, Alexandra has interned in multiple mental health institutions where she gained experience with different psychotherapy approaches and provided psychological support to various populations. Parallelly, her interest in social, political, and community psychology research and applications has motivated her to actively pursue relevant research opportunities.

Tamara Arh

Tamara received her BSc in Biopsychology from UP Famnit (Slovenia) and her MSc in Health & Social Psychology at Maastricht University (Netherlands).
