Behavioural science interventions advancing energy efficiency have mostly focused on consumer behaviour, with comparatively little work examining the important role that industrial consumers play in advancing the energy transition. Using the D.R.I.V.E.® framework, the project identified, analysed and consolidated the relevant literature and potential of behavioural science informed approaches to help SMEs become more energy efficient. Starting from a comprehensive review of the academic and…
Behaviorally informed messages have had demonstrated success in increasing tax compliance in multiple regional settings. In Indonesia, which has the largest economy in Southeast Asia, a trial from the Directorate General of Taxes (DGT) and World Bank teams looked at whether behaviorally informed messages and materials can impact tax compliance and payment rates among small and medium enterprises (SMEs). The results showed, to get delinquent firms to pay their taxes, information is not enough -…

We conducted a SMS program trial to inform our efforts to strengthen the home learning environment and support parents of 2 year-old children. Specifically, the trial aimed to: assess parent engagement with an SMS program, assess the impact of the program on positive parenting behaviours such as reading, playing and two way enriched conversation; and inform future efforts to improve positive parenting behaviours.
Why this experiment was conducted: scepticism about second-hand clothes
The clothing industry is a major polluter, and the second-hand market is an important alternative to new clothes. While more and more Dutch consumers are turning to pre-owned clothing, a large group remains sceptical. According to a target group study conducted in 2020, they wonder whether they will be able to find a suitable second-hand item, and whether it is hygienic. The best way to overcome this scepticism is to create…

Making sure that young people get vaccinated against HPV: How do you encourage both boys and girls…
A campaign was launched to encourage young people to get the catch-up vaccination against Human Papillomavirus (HPV). The campaign succeeded in promoting discussion and increased awareness of HPV as well as persuading young people to get vaccinated.
Why this experiment was conducted: provide boys and girls with a vaccine they might not have received
In 2022 and 2023, boys were invited for the first time and girls were invited again to get vaccinated against the Human Papillomavirus (HPV). HPV…
PROJECT SUMMARY
Students were sent two redesigned emails during the course selection process: a pre-registration email that laid out instructions and procedures for registration, and a post-registration email that notified students if any of their upcoming courses did not fit financial aid requirements.
IMPACT
The average aid award for students receiving both redesigned emails rose by $150.28 per student for the Spring semester compared with students who received neither email, with a total…

Applying behavioural science to decrease air contamination from woodheating in Ile de France
More than 480 000 people in Ile de France use an inefficient woodheating device releasing high quantities of particulate matters in the environment but do not always link air pollution and woodheating.
This project aimed to inform the inhabitants about this link and encourage them to renew their ancient devices and adopt good practices around woodheating.
281 households were equiped with particulate matter sensors and the DITP compared the evolution of contamination between groups, divided in…
Installation of large, moveable trash containers and trash cans in convenient locations made disposal of large trash bags and litter easier for residents of New York City public housing. A package of indoor and outdoor posters informed people of the new policy and encouraged them to use the new infrastructure.
Challenge
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…
