This online experiment tested various ways in which sustainability measures for homeowners are presented on the website verbeterjehuis.nl, ‘improve your home’. The variant emphasising that the sustainability measures are 'recommended for your personal situation' proved to be most effective. This addition acts as an incentive to homeowners to install roof insulation or adopt other sustainability measures.
Why this experiment was conducted: verbeterjehuis.nl website optimisation

Full price information for consumers: What effect does the way prices are displayed have on online…
The Netherlands Authority for Consumers & Markets (ACM) conducted an experiment to investigate the effect of incomplete prices when booking a holiday home. Websites that display incomplete prices cause greater uncertainty, make choosing more difficult, undermine trust and give the feeling of deception compared to websites displaying transparent prices.
Why this experiment was conducted: unclear picture of actual costs
In 2021, the ACM conducted a study into effective transparency. The aim was…

Safer road behaviour on N36 provincial road: how can a campaign targeting road users prevent…
Rijkswaterstaat conducted a behavioural campaign aimed at urging drivers on the N36 provincial road in Overijssel to keep a safe distance, to be calm and relaxed while driving and to pay attention to the road. The campaign achieved a reduction in distractions, less irritation and an overall improved driving experience.
Why this experiment was conducted: many serious accidents on N36
The spotlight has been on the N36 between Hardenberg/Ommen and Almelo/ Wierden for some time due to the frequent,…

Can Visual Cues to Portion Size Reduce the Number of Portions of Consumed? Two Randomized Controlled…
Methods
Two preregistered randomized controlled trials (N = 253 and N = 674) measured consumption in a lab and the home environment. Cues were salient, labeled stripes that demarcated single portions. Participants were randomized to cue condition or control. Consumption was measured without awareness.
Results
The main preregistered effect of the visual cue was not statistically significant. There was some variation by subgroup. In Study 1, men were more likely to eat the whole can of potato…
In Turkey, the years between 2012 and 2017 saw a steadily rising labor force participation rate but also unemployment. New workers, including women and youth, joined those already in the market increasing the competition for available jobs. At the same time, employers, reported difficulties finding workers with appropriate workplace competencies when filling vacancies, particularly when it came to job-related behaviors. The Turkish Employment Agency (ISKUR) and the World Bank teamed up to test…

Behavioral Interventions in Local Government: Increasing the Efficiency of Local Public Policies
The project had three aims. The first aim was to create a comprehensive catalogue of systematic, financially manageable behavioural interventions (including nudges and other interventions), as well as improvements to current processes and instruments of public administration at the local level in Slovakia. The second aim was to create a manual for the general application of behavioural knowledge to public administration practices, which includes a handbook for systematic and expert application…
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 data on research questions of interest to the promotion of climate action in Canada (e.g. transportation, home energy use, waste management, engagement with nature, preparedness for extreme weather,…

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…
Improving prevention in the area of mental health, destigmatizing the topic, improving awareness of the possibilities of help for different types of mental health problems, gradually breaking down the barriers that stand in the way of seeking professional help.
Problem: students do not know how to deal with mental discomfort and the onset of mental health problems, including those caused by pandemics.

Walk-in vaccination without an appointment: does the absence of the need to schedule a vaccination…
Could we expect a higher vaccine uptake if vaccination appointments are no longer necessary? A campaign in neighbourhoods where vaccination rates were lagging sought to test whether emphasising convenience led to an increase in the number of administered vaccinations, by offering walk-in vaccination without an appointment. This indeed proved to be the case. Furthermore, getting a COVID-19 vaccine on a walk-in basis has become popular, along with the platform PrikkenZonderAfspraak.
