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…
The Ministry of Justice and Security developed a behavioural intervention aimed at inspiring individuals to adopt safe cyber practices: 'Valse email? Meld het via de meldknop' (Fake email? Report it using the report button). Thanks to this behavioural intervention, employees are ten times more likely to report suspicious emails internally. Moreover, click rates on links in suspicious emails have significantly decreased.
Why this experiment was conducted: One in five SMEs have been victims of…

Levelling the playing field in police recruitment: Evidence from a field experiment on test…
How to increase diversity in the police is an unanswered question that has received significant political and media attention. One area of intervention is the recruitment process itself. This study reports the results of a randomized controlled trial (RCT) in a police force that was experiencing a disproportionate drop in minority applicants during one particular test. Drawing on insights from the literatures on stereotype threat, belonging uncertainty and values affirmation exercises, we…
Switzerland's Energy Strategy 2050 aims to reduce energy-related environmental pollution, for example by increasing the energy efficiency of individuals, households, and companies.
To help achieve this goal and raise public awareness of the issue, the Swiss energy provider Primeo Energie ran an energy-saving campaign (hereinafter referred to as the campaign) in winter 2023/24. Customers who consume significantly less energy in the winter of 2023/24 than in the winter of the previous year can…

Pre-contractual information and billing in the energy market – improved clarity and comparability
The study investigates minimum requirements and options for standardisation of energy offers and bills that ensure increased clarity and comparability, and puts forward better alternative “bill designs”. The study also examines the main factors discouraging energy consumers from switching, with a focus on the impact of exit fees in this decision. Finally, price comparison tools (PCTs) in the energy sector are examined and (independent) verification schemes for such tools are identified.

Generating more enthusiasm for teacher training programmes: How to get students more interested in…
In this experiment, various emails were sent to students in senior general secondary education (HAVO) and preuniversity education (VWO) to inform them about open days of teacher training programmes. The subject line that most caught their attention was ‘Are you looking for job security, challenge and a wide range of career opportunities?’ as well as a subject line in which a role model was introduced. Where emails mention teachers' starting salaries, students most often click links to more…

Electricity Information to Fit the Bill: Redesigning electricity bills to support consumer…
Electricity bills are a key way to inform people about their plan and usage, but bills can be confusing and are not really useful to help people navigate the electricity market. BETA and the Department of the Environment and Energy ran a trial to test the impact of bill design on people’s confidence in their ability to look for a better offer and intention to do so. We drew on behavioural insights to design and test six electricity bills. We focussed on simplifying bill design to draw…
BI Project
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…
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…
Pacific Island Nations are facing a crisis of Non-Communicable Diseases (NCDs) - chronic diseases which are the result of a combination of genetic, physiological, environmental and behavioural facts. NCDs are the leading cause of mortality in the region, accounting for 75% of deaths. Unhealthy diets in particular have been recognized as a risk factor for high rates of obesity. Residents of the Pacific Island Nations have some of the highest rates of obesity in the world, with 92.9% and 80.7% of…
