Using sustainable transportation alternatives can often be hindered by car dependence (Haustein, 2021). Within the context of Santa Monica, for example, approximately 75% of Santa Monica residents choose single occupancy vehicle (SOV) commutes to work, and over 50% of households own more than one vehicle (Data USA, n.d.). More generally, vehicle transportation accounts for 62% of greenhouse gas emissions in the city, making it the largest emissions contributor (Johnstone, 2021).

Conditional cash transfers are funds given to households if they fulfill certain requirements, such as sending their children to school. These cash transfers can boost households’ investment in health and education; however, they are expensive, and it is often complicated to track and enforce compliance with the requirements. Removing the conditions may make cash transfer programs more cost effective by decreasing administrative costs, while still providing a nudge to increase school…

Text messaging to spur vaccination take-up: which type of communication is most effective?
In early 2022, various kinds of text messages were sent to over 100,000 residents of Brabant-Zuidoost who had not yet received a booster jab from the GGD. The results show that the most effective variant − in the 6 days after receiving the text message − led to a 3.2% increase in the number of vaccinations administered. This was the text message saying 'Jouw boosterprik ligt voor je klaar' (You can now book your booster vaccination) plus a randomly allocated date, time and location.
Why…
We all know that if a 13-year-old has his mind set on
something, it is quite difficult to try to change it. This
is exactly the type of challenge that the Ministry of
Education in Peru is approaching with students in
public schools and high schools, targeting those from
low-income households in particular.
Teenagers often have pre-conceived ideas about their
own intelligence, which influences how they react to
academic challenges. If a student thinks he is not smart
enough, he believes there is…

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…
The OSGG supports the Governor General in recognizing, promoting, and cultivating excellence by Canadians to strengthen our national identity, unity, and pride. Central to these goals is nominating and appointing Canadian Honours, such as the Order of Canada, which celebrate and reflect the diversity of exceptional contributions that Canadians have made to their country. Maintaining the relevance of these Honours is important to sustaining a shared Canadian identity, and consequently cultivating…

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…

Tax delinquencies are a major problem for most tax administrations in the world. In Colombia, the National Accountant Office estimated the total outstanding debt to the National Tax Agency at $2.5 billion, which represents about 20 percent of estimated total tax evasion in 2014. Finding ways to reduce tax delinquencies is critical for both fiscal and equity considerations. A previous study compared messages about due liabilities delivered through three channels (letter, email, or…
