In an effort to boost COVID-19 vaccination rates, mobile vaccination units were rolled out in late 2021. This strategy proved successful: the number of vaccinations administered was between 1.1 and 14.5 times higher in neighbourhoods on the days they were visited by mobile units. The units were more effective in rural areas than in urban settings. In addition, they proved to be more effective than average in neighbourhoods with a higher proportion of SGP voters and still effective, although to a…

Encouraging the wearing of face masks in hospitality venues: how to ensure guests wear face masks in…
Due to the COVID-19 pandemic, guests were required to wear face masks on entering and while moving inside hospitality venues. To promote this behaviour, self-persuasion and salience techniques were used in this experiment - with notable success. Following the announced relaxation of face mask requirements, there was a decrease in face mask usage, although this was significantly less in hospitality venues that saw interventions than in venues that did not experience interventions.
Why this…
As of 2007, the UK Ministry of Justice was imposing over £350 million in new court fines annually, only half of which were collected within six months. In 2011, the Ministry faced over £600 million in outstanding unpaid fines.
Her Majesty’s Courts and Tribunal Service (HMCTS), which administers the collection of fines, incurs significant costs from non-compliant debtors. In addition to resources for case-management and follow-up phone calls, bailiffs are assigned to recover the debt…
Hospital-care-associated infections (HCAIs) represent the most frequent adverse event during care delivery, affecting hundreds of millions of patients around the world. Implementing and ensuring conformity to standard precautions, particularly best hand hygiene practices, is regarded as one of the most important and cheapest strategies for preventing HCAIs. The behavioural sciences have documented the potential of adjusting seemingly irrelevant contextual features in order to ‘nudge’ people…
The Health Quality & Safety Commission (‘the
Commission’) uses data from the National Adult
Inpatient Experience Survey to understand patient
experience and evaluate quality of patient care in
hospitals. Two questions (See Appendix 1A) pertaining to
patients’ understanding of medication side-effects and
condition management have consistently received low
scores on the survey every quarter. Ogilvy conducted
Phase 1 of ‘Raising the Bar’ research for the Commission,
investigating these…

Helping people get more out of language: How can you help individuals with limited literacy skills…
The 'Doe meer met taal' (Get more out of language) campaign was launched to reach out to individuals with limited literacy skills whose mother tongue is Dutch. At its conclusion, people in the target group said they felt more motivated to improve their language skills. They are also more inclined to take proactive steps, for example by engaging in language-related activities at home. 66,000 people visited the campaign website.
Why this experiment was conducted: everyone should be equipped with…
It’s the end of April in Poland. While everyone
is happy the harsh winter weather is finally getting
milder, the Polish Tax Authority is worried because
62% of the country failed to pay their taxes on time.
Over the past decade, the use of behavioral principles
by tax administrations in different countries has been
gaining ground. Given the country’s tax compliance
rate, Polish authorities and the World Bank tested the
use of behaviorally informed letters to late taxpayers
in order to…
In 2014, Tanzania’s regulators made the country
the first in Sub-Saharan Africa to permit interest
payments on mobile money wallets. Currently, annual
interest rates range from seven to nine percent, four
times greater than the average deposit in a US bank.
Despite this, mobile savings balances remain low,
especially among low-income users.
In order to understand what influences the saving
behaviors of low-income Tanzanians, our team, eMBeD,
together with the Consultative Group to Assist…
While potential voters may register and intend to vote, many registered voters ultimately do not participate in elections. In addition, previous studies have not addressed how the impact of the text messages may vary among causal voters compared to habitual voters. Casual voters are defined as those who had previously only voted in the presidential election or major elections. Habitual voters are defined as those who have a higher propensity to vote (in this case, those who voted in each of the…
