What if the secret to boosting productivity isn’t stricter rules or higher pay, but something as simple as giving workers a voice? Sherry Jueyu Wu shares a field experiment from the production floors of a Chinese factory, which asked whether participatory meetings – in which workers spoke and supervisors listened – could increase productivity. The answer is yes. These findings challenge conventional wisdom about hierarchy and efficiency, and suggest that voice may be a powerful yet underutilized tool for organizations.

When we talk about behavioural interventions, we often need to simplify complex concepts, but this can leave critical questions unanswered. The META-BI framework provides shared terminology to foster clearer and more productive behavioural science discussions, across disciplines and with practitioners.

A one-size-fits-all approach to nudging can be ineffective, or even backfire. Personalising nudges is a way of recognising and acting upon known heterogeneity across and within groups of people to deliver successful behaviour change.

Recommender systems are online algorithms that can help users, reducing complexity and search costs. But they also target and exploit behavioral biases. Recommender systems lend themselves to regulation through 'budges'.

System change and individual behavior change are often conceptualized as mutually exclusive strategies for climate change mitigation – but what if this duality is misguided? Denise de Ridder and Sander Thomaes map four pathways illustrating that system change is effective when it promotes behavior change and vice versa.

AI safety discussions predominantly focus on easy to conceptualise, highly salient risks including algorithm bias, hallucinations and disinformation. While these are crucial concerns, they overlook a fundamental truth we've learned from other high-stakes fields like aviation and healthcare: sometimes the most dangerous risks can hide in plain sight. Dr Moira Nicolson and Holly Marquez (Government Communications, Cabinet Office, UK Government) introduce a framework for anticipating and managing these risks, supporting a safer rollout of AI use in the public sector and beyond.

From keynote visions of ‘Behavioural AI’ to field experiments on job matching and green transport, the 2025 BPP Workshop in Singapore showcased how rigorous behavioural science meets real-world policy. Two days blended cross-disciplinary panels, data-rich case studies and Marina Bay networking, sparking fresh collaborations across sustainability, labour, finance and AI.

What if climate communication could enhance support for unpopular but necessary policies? Valerie Dewaelheyns and colleagues show that collective action framing can increase public acceptance of climate adaptation policies and strengthen citizens' belief in society's collective power to tackle climate change.

As global temperatures rise, so does our reliance on air conditioning (AC), which accounts for 7% of global electricity use in 2022. But what if the solution to sustainable cooling is not just about better AC technology to cool the entire space, but about changing our behaviour to cooling ourselves? Maggie Yang explores how social norms can encourage office workers in China to adopt personal cooling strategies, potentially saving energy while maintaining comfort.

Academics and civil servants have an interest in effective collaboration and “knowledge exchange”, including the sharing of ideas, evidence and expertise. However, the two sectors have different ways of operating and different – sometimes competing – goals. If they can understand each other better, then they can get the most out of working together.

Tax compliance remains a thorny issue for governments worldwide—especially in developing countries where informal economic activity, mistrust in government, and limited enforcement capacity create persistent gaps between potential and actual tax revenues. Can a few carefully worded text messages make a difference?

Air pollution is a worldwide challenge. Despite the serious environmental and health effects, pollution can go unnoticed until very dangerous levels are reached. Rita Abdel Sater, Mathieu Perona, Elise Huillery and Coralie Chevallier use a novel and safe method to make pollution more visible, and demonstrate that personalised feedback can change household behaviours. The Great Smog of London: when pollution became impossible to ignore…

The IPCC suggest that a further 40-70% reduction in greenhouse gas (GHG) emissions could be achieved with more extensive sustainable behaviour change. Yet, when this change impinges on our daily lives, some initial pushback is inevitable. This article explores how trust, fairness, and transparency create conditions in which people feel confident to embrace lifestyle changes to benefit their own health and the future of the planet.

Mathieu Prevelato introduces a new study exploring policy makers’ views on the ethics of behavioural public policy, and invites feedback on it.

Policymakers often introduce programs to encourage businesses to adopt environmentally friendly practices. But even minor administrative hurdles - known as "sludge" - can significantly reduce take-up of sustainable practices. Manuel Grieder, Deborah Kistler and Jan Schmitz draw on a field experiment with Swiss firms and offer ways forward.

Misinformation thrives in an environment where platform providers shape the rules yet evade responsibility. As companies like Meta and X dismantle fact-checking and relax content moderation, users are left to navigate a fragmented and often deceptive digital landscape. But behavioural science offers solutions. In this blog, Christoph M. Abels walks us through the strategies that help individuals critically assess information, resist manipulation, and adapt to a world where platforms no longer seriously attempt to verify content for accuracy.

Ivo Vlaev and Marco J Haenssgen argue that research and policy collaboration with indigenous communities is key to long term conservation success.

In our first blogpost of 2025, Leonhard Lades and Kate Laffan look ahead to the exciting events and opportunities for the IBPPA community. Hope you can join us! Get involved, stay informed, become a member. A lot is happening in the world of behavioural public policy (BPP)! While BPP is still a relatively young scientific field, the activities happening this year suggest that we are maturing and growing, which is looking promising for the future.

Ivo Vlaev, Professor of Behavioural Science, University of Warwick New Year’s resolutions represent more than just a fleeting tradition; they offer a powerful opportunity for self-reflection and intentional growth. Rooted in six fundamental psychological needs shared by all humans, resolutions serve as a catalyst for meaningful change. Here’s why they matter and how they can transform lives. 1. Reflection and Growth…
