The 'Health, Attitudes, and Behavioural Insights Trends' (HABIT) survey, combines research methods from the field of behavioural science (BeSci) with robust policy analysis to help inform government policies, programs, and…

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…

Improved registration of development cooperation activities: How can an application ensure correct…
In a move aimed at improving how it registers its development cooperation activities, the Ministry of Foreign Affairs developed an application: IMPACT. This was successful in enabling budget holders to report activities more correctly: activities now have shorter names and are reported in English more often than previously. However, budget holders continue to use non-standard abbreviations.
Why this experiment was conducted: reports do not always comply with appropriate standards
The Ministry…
In Haiti, more than 96 percent of the population is exposed to two or more natural hazards in theirlifetime. The human and economic impacts of these hazards, including hurricanes, floods, earthquakes, and landslides, have been severe. Between 1961 and 2012, the country experienced more than 180 disasters, causing the death of more than 240,000 people. Many disaster-related fatalities are preventable if people evacuate to a safer place in a timely fashion. However,in Haiti, due to a variety of…

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…

Can interventions in supermarkets reduce household food waste? A randomised controlled trial of…
The study was conducted in collaboration with eight supermarkets from two of the largest Swedish supermarket chains. The stores provided the natural environment in which to conduct an experiment using real shoppers and real purchases, without shoppers being aware of the study. Four different interventions (different price displays) were designed, based on insights from behavioural science. These signs were tested in a randomised controlled study for two common and perishable vegetables –…

Website Verbeterjehuis.nl helps homeowners choose the right sustainability measures: which…
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

Empirical testing of the impact on consumer choice resulting from differences in the composition of…
Differences in the composition of seemingly identical branded food products (DC-SIP) has been a source of growing concern in the EU in recent years. This was particularly the case after tests conducted in several Member States (MS) confirmed the presence of differences in composition of some branded food products sold across different Member States. This report aims to contribute to the existing studies by verifying whether the presence of DC-SIP influences consumer preferences and willingness…
This project leverages an online survey experiment among federal employees involved in the process of translating information and evidence about a program into actionable policies and programs. The experiment’s primary aim is to test ways of presenting information to improve sensitivity to impact-relevant information about a program. The impact-relevant features tested are: the number of people impacted, the intermediate or final outcomes and the persistence of effects. In addition, the…
