emand within the Child Protection system has grown significantly over the last decade.
The education sector is a particularly important stakeholder. Teachers and other school staff interact with children regularly and are often the first to notice if a child is at risk or needs support.
This project sought to better understand the decision making process of professionals from the education sector, Child Protection Intake and Child FIRST lead agencies for identification of whether a child is…

Less waste placed next to underground containers: is there a reduction in the amount of waste left…
The Municipality of Dordrecht organised a competition titled The Cleanest Neighbourhood in Dordrecht. The aim was to get residents to place less rubbish next to underground waste containers. As a result of the experiment, the amount of waste left next to bins decreased and a new social norm was established.
Why this experiment was conducted: rubbish left next to waste containers
Bin liners and other bags containing residual and larger waste left next to underground containers rank amongst the…
This project was led with the French National Forestry Office (ONF), which is an institution responsible for the management of public forests, under the supervision of the Ministry of Agriculture and Food and the Ministry of Ecological Transition. Our common project has studied how to apply behavioral science to enhance user safety in forests. It resulted in the generation of 17 Nudges. Experimentation is expected to start spring 2022.

Whāriki Haumaru: Encouraging voluntary participation at court for people with outstanding Warrants…
We seek to increase voluntary appearances for people with outstanding Warrants to Arrest (WTA) through reminder phone calls from Māori Wardens and Police. This Auckland-based project follows a proof-of-concept trial in the Eastern District, in which Māori Wardens made phone calls to people with outstanding WTAs and we compared voluntary appearance rates for those who were reached via phone to those who were not.
While this trial in the Eastern District showed indicative evidence that phone…
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 -…

Comparing the impact of positive, negative, and graded sustainability labels on purchase decisions
An online experiment with EU consumers was run to assess the relative effectiveness of three sustainability labelling approaches: (1) positive labels - only identifying products with the best sustainability performance, (2) negative labels - only identifying products with the worst sustainability performance, and (3) graded labels - conveying the relative sustainability of all products. Results suggest that graded labels are the most effective to steer consumer toward more sustainable purchase…

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…
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…

Feel & act green: can compliments about sustainable behaviour lead to the next sustainable…
Rijkswaterstaat (the Directorate-General for Public Works and Water Management) wants to induce behavioural change in several areas. The circular economy is one example. A study examined whether consumers will make more sustainable choices if they have been complimented on their past actions or behaviour that were environmentally friendly or sustainable. This proved to be the case.
Why this experiment was conducted: additional incentive for sustainable behaviour
Behavioural change is…
