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.

Tax delinquencies are a major problem for most tax administrations in the world. In Colombia, the National Accountant Office estimated the total outstanding debt to the National Tax Agency at $2.5 billion, which represents about 20 percent of estimated total tax evasion in 2014. Finding ways to reduce tax delinquencies is critical for both fiscal and equity considerations. A previous study compared messages about due liabilities delivered through three channels (letter, email, or…
Previous research by the Program of Applied Research on Climate Action and the Environment (PARCA) team has found that Canadians generally display poor understanding of the relative impacts of different pro-climate actions and have gaps in their understanding of climate change. Following up on these findings, a randomized controlled survey-experiment was conducted in December 2023 to test the impact of several behaviourally-informed interventions on climate literacy outcomes. Results suggested…

Strategies to work on the encouragement of breastfeeding with the health teams of the first level of…
The commercialization of formula milk (FM) began in Argentina at the end of the sixties. This market has grown remarkably since then, in turn, state agencies use LF as a tool to solve or combat low-weight problems in children and who for other reasons need to supplement the diet when milk is not possible exclusive breastfeeding (EBF).
The increase in LF consumption is detrimental to breastfeeding (BF). Its introduction generates a vicious circle and dependency that is difficult to reverse…

Nudge vs Superbugs: a behavioural economics trial to reduce the overprescribing of antibiotics
BETA and the Department of Health ran a trial to test the impact of personalised letters from Australia's Chief Medical Officer to high-prescribing GPs prompting them to consider reducing antibiotic prescribing where appropriate and safe.
30% of the requests CNAM (Primary health care institution in France) receives by phone or email could be made and treated online. In order to encourage use of online services, the CNAM solicited help from the DITP. This dematerialization would benefit the user by easing the access to services, to the administration workers by improving their work conditions and to the institutions through gains in efficience.
We chose to target a precise procedure: ordering a Carte Vitale (Health Care card) for…
In a seven-week school-based field experiment using preadolescents’ physical activity as a proxy for estimating behavioural change, we test the hypothesis that boys’ and girls’ distinct networks are susceptible to different social incentives.
Using sustainable transportation alternatives can often be hindered by car dependence (Haustein, 2021). Within the context of Santa Monica, for example, approximately 75% of Santa Monica residents choose single occupancy vehicle (SOV) commutes to work, and over 50% of households own more than one vehicle (Data USA, n.d.). More generally, vehicle transportation accounts for 62% of greenhouse gas emissions in the city, making it the largest emissions contributor (Johnstone, 2021).
However,…
In 2014, Tanzania’s regulators made the country
the first in Sub-Saharan Africa to permit interest
payments on mobile money wallets. Currently, annual
interest rates range from seven to nine percent, four
times greater than the average deposit in a US bank.
Despite this, mobile savings balances remain low,
especially among low-income users.
In order to understand what influences the saving
behaviors of low-income Tanzanians, our team, eMBeD,
together with the Consultative Group to Assist…
Oxera and the Centre for Experimental Social Sciences (CESS) conducted a behavioural experiment on behalf of the Financial Conduct Authority (FCA) to identify the effectiveness of certain summary cost metrics in aiding consumer selection of income drawdown products
