We conducted a systematic search for an overview of reviews of scholarly evidence on scale up, and 11 practice interviews with behaviour science researchers and practitioners to identify the factors and activities that influence the scale up of behaviour change interventions, learn about scale up, its challenges, and useful frameworks, identify which behaviour to target with an intervention, assess the feasibility of different intervention ideas, and select a scalable behaviour change…

To reduce the speed of motor vehicles on the Yarze highway, Nudge Lebanon, in collaboration with the Traffic Management Centre (TMC), placed a salient image of overlooking eyes, coupled with a message informing drivers that their speed was being monitored on a Variable Message Sign (VMS). Vehicles in treatment time slots, with speeds above 100km/h reduced their speed by around 11.5% compared to similar vehicles in the control group. Moreover, compared to the control group, the treatment was more…

Measuring the effect of community based social marketing on the rate of application for home energy…
In Ireland, grants for retrofitting homes with energy upgrade measures are available from the Sustainable Energy Authority of Ireland. Improved energy efficiency of households is an important aspect of Ireland’s climate emergency related targets.
Barriers to retrofitting include a lack of understanding about retrofitting and the process, and a lack of awareness of grant availability. Community based social marketing (CBSM) might be an effective way of increasing uptake because it addresses…
The project’s goal was to increase voter turnout among potential voters: registered voters who participated in one or fewer primary elections since 2000. Voting is a high-salience, socially important behavior that is essential to a functioning democratic society. While campaigns and organizations spend millions of dollars to increase voter turnout, recent research suggests that simple interventions like facilitating plan-making can help people follow through on their intentions.
Switzerland's Energy Strategy 2050 aims to reduce energy-related environmental pollution, for example by increasing the energy efficiency of individuals, households, and companies.
To help achieve this goal and raise public awareness of the issue, the Swiss energy provider Primeo Energie ran an energy-saving campaign (hereinafter referred to as the campaign) in winter 2023/24. Customers who consume significantly less energy in the winter of 2023/24 than in the winter of the previous year can…
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…
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 -…
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…
Online experiment tested two novel public health messages on social distancing.
•Messages focused on potential to infect vulnerable people or many people.
•Participants (N = 500) randomized to see control or (one of two) treatment posters.
•Behavioral intentions and acceptability judgements of behaviors measured later.
•Both posters increased caution with respect to social distancing.
