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...

Nutritional labelling is a means of communicating the nutritional content of food to consumers. When a nutritional label is salient and understandable, consumers tend to make more healthy choices. Nutritional labelling policies can also influence providers by incentivising manufacturers to...

Transitioning to the green economy relies on new developments that may negatively affect people's localities and involve certain risks. This study investigates how people form opinions about such developments, using mineral exploration and mining as an example. A representative sample (N=1000)...

Replacing car travel with walking and cycling lowers emissions, improves air quality and makes communities healthier. Rates of active travel typically increase when dedicated infrastructure is implemented. But policymakers in multiple countries regularly contend with two obstacles: designing...

This study demonstrates how status quo bias (SQB) acts as an obstacle to active travel policy. A pre-registered experiment was undertaken to measure the strength of SQB and to illuminate its likely causes. A large, nationally representative sample evaluated descriptions of a town layout designed...

The "obesogenic environment" contributes to the global obesity epidemic. However, many believe that obesity is caused solely by individual choice. This paper investigates how the public in Ireland, the UK, and USA perceive the causes, consequences and severity of obesity compared to an expert...
