We hypothesise and confirm a previously unnoticed pattern within pre-existing data on the endowment effect, collected via seven experiments employing the original design. Subjects with low valuations in binary choice relative to other subjects set a proportionally higher willingness to accept....

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...

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...

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...

We present evidence from two experiments designed to quantify the impact of cognitive constraints on consumers' ability to identify surpluses. Participants made repeated forced-choice decisions about whether products conferred surpluses, comparing one or two plainly perceptible attributes...
