In a pre-registered experiment, we tested whether expert endorsement increases the effectiveness of debunking messages about COVID-19 vaccines. We monitored a sample of 2,277 people in Italy through a longitudinal study along the salient phases of the vaccination campaign. Participants received a series of messages endorsed by either medical researchers (experimental group) or by generic others (control). In order to minimise demand effects, we collected participants’ responses always at ten…

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).

To reduce the speed of motor vehicles on the Yarze highway, Nudge Lebanon, in collaboration with the Traffic Management Centre (TMC), placed a salient image of overlooking eyes, coupled with a message informing drivers that their speed was being monitored on a Variable Message Sign (VMS). Vehicles in treatment time slots, with speeds above 100km/h reduced their speed by around 11.5% compared to similar vehicles in the control group. Moreover, compared to the control group, the treatment was more…

Using protection motivation theory in the design of nudges to improve online security behavior
Online experiment to explore the effect of notifications on security behaviour. Both increased secure behavior – but the coping message significantly more so. The coping message was also as effective as both messages combined, but not so the threat appeal. Risk attitudes, age and country had a significant effect on behavior.

Research suggests that some students—including low-income, underrepresented minority, and first generation students—avoid applying for financial aid due to a combination of psychological reasons. Some are overwhelmed by the complexity of the process, while others worry they’ll feel out of place in college or be stigmatized for their socio-economic background. These psychological factors can cause students to avoid applying for aid, or fail to complete their financial aid…

Implementation of a chatbot based on behavioral strategies to promote the continuity of vaccination…
Despite the overwhelming medical evidence on the protection offered by the second, third and fourth doses of the Covid-19 vaccine, the acceptance of these doses remains low despite the existing supply. The problem is likely because there are currently no reminders in the province of Chaco, Argentina. This makes it difficult for residents to know if they are eligible for the next dose of the COVID-19 vaccine and where to access it.
Booster vaccination is associated with a lower risk of mortality…
Challenge
Many eligible college students fail to apply for financial aid offered by the federal government altogether. Of those who do apply, many more reduce their chances of receiving aid by failing to apply by the priority deadline. In the 2013-2014 school year, more than 80% of students at Arizona State University who filed their financial aid applications did so after the priority deadline had passed, which can result in a lower aid package. This project’s goal was to increase the number…
In a randomised trial we sent reminder letters to self-employed entrepreneurs about their upcoming VAT filing date. Previously it was not common practice for the Hungarian tax administration to send large scale reminders before the due date.
In partnership with Environment and Climate Change Canada (ECCC) and Natural Resources Canada (NRCan), the Impact and Innovation Unit (IIU) has launched a multi-year program of research on climate change. The Program of Applied Research on Climate Action in Canada (PARCA Canada) combines behavioural science (BeSci) insights and methods with robust policy analysis to promote climate action. One of the main areas of focus involves the launch of a longitudinal survey that will, over time, collect…
