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…
Small businesses were sent behaviorally-informed emails encouraging them to apply to the Growth Vouchers program.
A key part of the Department for Business, Innovation and Skills’ (BIS) remit is to provide support to small businesses in the United Kingdom. BIS has explored a number of initiatives to help these businesses grow.
One of these initiatives was ‘Growth Vouchers’ – a program of matched funding with a £30 million budget. Businesses could apply for funding to help subsidize the…
Despite email alert systems having a large reach, email can be a difficult platform to spread awareness. BETA partnered with the Australian Cyber Security Centre (ACSC) to find ways of boosting the impact of an email alert system. We applied behavioural insights to the email design to bolster its effects, and tested these different design aspects using a randomised controlled trial. Subscribers were randomly assigned to receive an alert with one or more of our new design features (or a…
The problem
Missed appointments are a significant cost to the health care system, and patients who do not attend appointments miss out on valuable care.
What we did
We partnered with the Department of Health and Human Services and several health services to improve patient communications as part of a new Communications Toolkit for health services.
To understand what works, we designed a range of behaviourally-informed SMS reminders and letters to reduce the number of patients who do not attend…
BI Project
Effective position of call-to-action: Is the response rate higher if the call-to-action appears the…
How can response rates to questionnaires be increased? In the first quarter of 2023, some of the participants in a CBS survey received a letter in which the call-to-action appeared as far as possible at the top of the letter. The other participants received standard letters. The analyses showed that the standard letters produced a significantly higher response rate than the letters in which the call-to-action was placed at the top.
Why this experiment was conducted: high response rate is…
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…
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…
The Charter of Rights and Responsibilities of Financial Consumers is an initiative designed to counteract consumers' optimism bias and the information asymmetry that typically favors banks over users.
To address these behavioral and structural challenges, the initiative employs smart disclosure techniques, including the use of visual prominence and icons to guide users' attention when interacting with the document.
This charter is mandated to be displayed physically at bank branches, digitally…
A Randomized Controlled Trial (RCT) was conducted at seven of Amel’s community centers to improve the performance of students sitting for Cycle I exams. The trial consisted of a short activity that comprised of a ranking exercise whereby they have to rank a list of 10 values from most of least important to them, followed by a drawing exercise in which they have to visualize their number 1 value [9]. Both exercises were completed by students right before sitting for their exams.
The general objective of this project was to test the effectiveness of presented information to retail investors. The overall aim is that the information provided should be well understood by retail investors and allow them to compare and select among different investment products.
