Encouraging consumers to seek out and switch to lower-rate mortgages is important both for the individual consumer's finances and for functioning competitive markets, but switching rates are low. We conducted an experiment with mortgage-holders to test whether official advice on how to select...

Identifying whether hyperbolic advertising claims influence consumers is important for consumer protection, but differentiating mere "puffery" from misleading advertising is not straightforward. We conducted a pre-registered experiment to determine whether pseudo-technical advertising claims...

This paper summarises useful evidence from behavioural science for fighting the COVID-19 outbreak. It is based on an extensive literature search of relevant behavioural interventions and studies of crises. The findings aim to be useful not only to government and public authorities, but to...

Self-isolation is a vital element of efforts to contain COVID-19. We report an online experiment with a nationally representative sample (N=500) that tested behaviourally informed decision aids to support self-isolation. The experiment had three stages that tested interventions designed to help...

Radon exposure in homes is a leading cause of lung cancer, but the rate at which householders test for it is low. In a pre-registered experiment with a nationally representative sample of adults (N = 1,700), we used psychological theory to design interventions to increase perceived risk from...

How do people perceive and integrate multiple contextual risk factors for COVID-19 infection? We elicited risk perceptions from a nationally representative sample of the public (N = 800) using three psychologically-distinct tasks. Responses were compared to a sample of medical experts who...

Contact-tracing mobile phone apps have the potential to play a role in controlling the spread of COVID-19, but their success hinges on widespread uptake by the public. We report a study that behaviourally pre-tested COVID Tracker, Ireland's contact-tracing app, prior to its launch with a large...

In this study, a large, representative sample of the Irish population undertook a multiple-choice quiz about climate change. The 10-minute quiz was designed to engage participants and to measure their understanding, not of facts and figures, but of the scientific relationships behind climate...

Social distancing during the COVID-19 pandemic will save lives. We tested communication strategies to promote social distancing via an online experiment (N = 500) commissioned by Ireland's Department of Health. A control group saw a current informational poster. Two treatment groups saw similar...
