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...

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...

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...

The current strategy to end the COVID-19 pandemic is to achieve herd immunity through mass vaccination. This relies on individuals' willingness to take a vaccine. Yet little is known about how people perceive the risks and benefits of the COVID-19 vaccine. This paper reports the results of a...

With the ongoing rollout of smart meters in Ireland, time-of-use (ToU) tariffs are currently being introduced as a new way to pay for electricity. Such tariffs can bring important benefits to both consumers and society, in terms of reduced electricity bills and CO2 emissions, respectively. At...

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...

Many households lack savings to cushion them from financial shocks. While behavioural economics offers insights into why some households who want to save may fail to do so, successful behavioural interventions to increase precautionary saving are elusive. We incorporated multiple evidence-based...

We report a multi-stage online experiment (n=1,320) that tested multiple hypotheses regarding the presentation and communication of solutions for people with problem debt. We report four main findings. First, decision trees made it easier for people to locate solutions appropriate to their...

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...

Generations differ in their contribution to climate change and susceptibility to its effects. Framing climate change as an intergenerational issue may therefore alter public engagement. We report a pre-registered, online experiment with a youth sample (N = 500, aged 16-24 years) that tested...
