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 sample of smartphone users. The study was funded by the
Department of Health and run in co-operation with the app’s developers, NearForm.
Participants were randomised to receive different versions of a…

Filing tax returns correctly and on time: Is there value in expressing thanks to citizens and…
Are people more likely to file their tax returns correctly if they receive a thank-you in advance or afterwards? Analyses show that thank-you messages have no effect on compliance behaviour.
Why this experiment was conducted: positive alternative sought
To encourage citizens' tax compliance (i.e., paying their taxes on time and correctly), it is occasional practice to emphasise the risk of checks and fines in case of non-compliance. One drawback of this deterrent method is that it can damage…

The COVID-19 pandemic, the war in Ukraine, and other social and global political crises and incidents have increased the need to understand the mental resilience, preparedness, agency and sense of community of Finns in various crises and disruptions. This memorandum presents information related to these topics collected via the Citizens’ Pulse survey and citizen interviews commissioned by the Prime Minister’s Office in March and April 2022.
The Australian Government has a range of programs available to assist those experiencing drought. But despite help being available, many do not reach out. The Behavioural Economics Team of the Australian Government (BETA) worked with the Joint Agency Drought Taskforce to research the barriers preventing people from seeking help.
We sought to:
• understand the most effective forms of communication about available forms of assistance, and incentives to take up assistance; and
• understand the…
Current psychological research has focused a great deal of studying susceptibility to misinformation across a single domain (e.g. COVID-19, Climate Change, etc...). It's not well understood if susceptibility is dependent on the content and context of misinformation. To address this, our team will investigate which predictors of susceptibility are consistent across topic areas.

This experiment involved making the information on the WBSO website clearer and more personally relevant to entrepreneurs. The visibility of the call-to-action was also enhanced. The study showed that entrepreneurs were prompted to spend more time exploring the possibilities offered by the Research and Development (Promotion) Act (WBSO) and that they read the information more carefully.
Why this experiment was conducted: number of new applications below expectations
The Research and Development…
The project’s goal was to increase voter turnout among potential voters: registered voters who participated in one or fewer primary elections since 2000. Voting is a high-salience, socially important behavior that is essential to a functioning democratic society. While campaigns and organizations spend millions of dollars to increase voter turnout, recent research suggests that simple interventions like facilitating plan-making can help people follow through on their intentions.
In Haiti, more than 96 percent of the population is exposed to two or more natural hazards in theirlifetime. The human and economic impacts of these hazards, including hurricanes, floods, earthquakes, and landslides, have been severe. Between 1961 and 2012, the country experienced more than 180 disasters, causing the death of more than 240,000 people. Many disaster-related fatalities are preventable if people evacuate to a safer place in a timely fashion. However,in Haiti, due to a variety of…

This Auckland-based project follows a proof-of-concept trial in the Eastern District, in which Māori Wardens made phone calls to people with outstanding WTAs and we compared voluntary appearance rates for those who were reached via phone to those who were not.
While this trial in the Eastern District showed indicative evidence that phone…
