In many countries, the approach to tackling violent crime has been dominated by two ideas for generations. On the one hand, use bigger sticks, like longer prison sentences; on the other, use bigger carrots, like more economic opportunities, to make crime a less attractive choice.

Both of these pillars of policy - enforcement and opportunity - rest on a fundamental assumption - that people are making rational decisions before they act. What if, for the vast majority of violent incidents, that assumption is wrong?

What if the story of violence is less about good vs. evil, or poverty vs. wealth, and more about the way the human mind reacts to pressure?

In this episode of the BIT Podcast, recorded at the Safer Streets Conference in London, Michael Hallsworth, BIT's Chief Behavioural Scientist explores a different way of thinking about violence - one rooted in behavioural science.

We hear from:

🎙️ Jens Ludwig, University of Chicago Professor and co-author of the book Unforgiving Places - on the stubborn problem of violence and challenging the status quo

🎙️ Dr Chico Tillmon, Executive Director of the Community Violence Intervention Academy at the University of Chicago - on programmes designed to reduce serious violence

🎙️ Oeindrila Dube, Professor of Global Conflict Studies at the University of Chicago's Harris School of Public Policy - on working with the Chicago Police Department to train officers in de-escalation skills

🎙️Jennifer Doleac, Executive Vice President at Arnold Ventures - on which interventions will have the greatest impact

Social norms can change rapidly — sometimes sparked by viral moments, other times by subtle cultural shifts. Can behavioural science not only explain these changes — but help shape them?

Recorded at the Behavioural Exchange conference #BX2025 in Abu Dhabi, Michael Hallsworth, BIT's Chief Behavioural Scientist, dives deep into the science behind these shifts - asking the question 'What can behavioural science tell us about changing social norms?'

We hear from:

🎙️ Nikos Nikiforakis, Professor of Economics at NYU Abu Dhabi and Director of the Center for Behavioral Institutional Design - on what triggers norm shifts, what holds them back, and why "social pioneers" matter.

🎙️ Elke Weber, Eindlinger Professor for Energy and Environment at Princeton University - how individual choices ripple into collective change

🎙️ Rasha Attar, Director of the UAE's Behavioural Science Group - on how leadership and policy can act as catalysts for societal shifts

🎙️ Barbara Fasolo, Director of the Behavioral Lab of Research and Teaching at the London School of Economics - takes us inside organisations to explore how internal norms evolve and how to overcome the biases that slow them down.

What drives change, and how can we harness it? Tune in for a fascinating look at the evolving rules of society, and the science that might just shape its future.

The Behavioural Insights Team have spent the last 10 years developing solutions that are informed by behavioural science. These insights do not emerge overnight. Instead, they are grounded by a firm understanding of the systems in which we operate. Reading academic (or policy) papers is an important step to developing evidence based interventions, but it will only get you so far if you want to understand the context in which you want to implement an intervention. Instead, we argue that you need to leave the office and try to experience the context as closely as you can, either by directly experiencing it, or by directly speaking to the people that do.

To try to convince you that you should step away from our desk, we've created a podcast which we think will give you a much better sense of why you can't read your way out of a complex policy problem. In this podcast, Alex Gyani and Rory Gallagher from BIT's Sydney office speak to Zoe Powell, Saul Wodak, Allison Wong, Edwina Crawford and Sophie Munroe about their experiences of going out into the field and some of the insights they took from that process. We'll describe projects that have tackled domestic violence, unemployment and the health and safety of gig economy workers. If you want to know more about those specific projects, just follow the links posted in this description.

Note: that this podcast describes the court processes involved in domestic violence cases. While no acts of violence are described in the podcast, if you are affected by domestic violence or abuse, there are a number of services you can reach out to.

Australia: Call 000 if you are in immediate danger. To access 24/7 counselling and support call 1800RESPECT on 1800 737 732.

New Zealand: Call 111 if you are in immediate danger. Call 0800 456 450 free from any phone, 9am to 11pm every day.

UK: Call 000 if you are in immediate danger. For free and confidential advice, anytime call 0808 2000 247.

US: Call 911 if you are in immediate danger. For free and confidential advice, anytime call 1800 799 7233.

Behavioural science has made a major impact on important issues over the past decade, such as antimicrobial resistance, educational attainment, and sustainability. But it's also clear that applied behavioural science needs to evolve to fulfil its true potential.

BIT has just published A Manifesto for Applying Behavioral Science - a landmark guide to the future of applied behavioral science. This Manifesto takes a clear-eyed look at challenges facing the field and offers 10 proposals to address them:

Use behavioral science as a lens that can help us see all issues better, rather than as a tool for limited challenges.

Build behavioral science into the design of organizations' standard processes, to give it scale and sustainability.

Step back, understand the system, and use behavioral science to make targeted changes that lead to wider results.

Improve randomized controlled trials to better deal with the complexity of the real world.

Approaches successful in one context can fail in another – find out why, and how we can adapt them better.

Don't just think about biases in behavior – aim for practical theories that offer reliable ways of solving real-world problems.

Predict what people will do, confront when you were wrong, and change your views accordingly.

Be humble about what you know, more curious about why people do things, and help others use behavioral science to improve their own lives.

Use data science to identify, understand and reduce inequities. Be realistic – recognize that behavioral scientists always bring their own values to whatever they do, and help the field to broaden its range of perspectives.

In this episode the Manifesto's author and Managing Director of BIT in the Americas, Michael Hallsworth, takes to the streets of New York City to explain more about what point 3, the importance of 'understanding the system' means in the context of behavioural science. The journey will take him from Times Square to Governors Island, discussing oysters, pedestrian crossings, plastic bags and much more.

New research in BIT's 'How to build a Net Zero society' report finds that most people find it hard to make more sustainable choices in their own lives, despite 9 in 10 wanting to do so. They want to see strong leadership from government and business to make green choices easier.

These high levels of public support aren't just in the abstract - there are big majorities in favour of a whole host of specific policy recommendations, including many often deemed more controversial.

Listen to the team discuss this new research and what it means for how behavioural science can help reach Net Zero. The 'How to build a Net Zero society' report can be downloaded here: https://www.bi.team/publications/how-to-build-a-net-zero-society/

This episode looks at recent work from the team in the areas of road safety, online fraud, conflict resolution and synthetic data.

Over the past decade, car crash death rates in the US for pedestrians rose by 36%, even as death rates fell for drivers and passengers. Over a third of San Francisco's traffic deaths are caused when drivers make left turns and don't see the person in the crosswalk. BIT's Lis Costa is joined by Maximillian Kroner from our US office to discuss a pilot study conducted by BIT on the roads of San Francisco that reduced average speeds of cars approaching potentially dangerous turns by 17%.

If you're not familiar with the concept of synthetic data you are not alone but its potential in the fields of behavioural science and policy research is considerable. BIT's Head of Data Science and Technology Dr Paul Calcraft spoke to BIT's Aisling Colclough to explain more.

Boko Haram in Nigeria has been conducting a violent campaign against the authorities for many years but increasingly members are turning away from the militant group, expressing remorse and asking to rejoin the society they were previously terrorising. BIT's Dr Antonio Silva talks about the work the team have been doing to help with this reconciliation and reintegration challenge.

Finally this episode features a project from BIT France looking at how to help protect people from the ever present risk of online fraud. This project was run with and financed by the DITP - France's Département for Public Transformation. Tom McMinigal from BIT France speaks to BIT's Andrew Schein about his experience pretending to sell coffee machines through a fake online scam to help teach people how to avoid the actual ones.

In the second of a two-part climate change special, BIT's Head of Energy & Sustainability, Toby Park, sits down with Cambridge University's Professor Theresa Marteau, Moira Nicolson from the Cabinet Office and Valentine Quinio from the Centre for Cities to unpick three of the biggest areas we need to decarbonise to reach Net Zero by 2050: Food, Transport and Energy.

We know we cannot achieve Net Zero without behaviour change - the question is, how we can make it happen and devise effective solutions to decarbonise the way we produce and eat food, the way we travel and the way we heat and power our homes.

Our guests discuss the barriers that prevent us from eating more sustainably, uptaking public transport and electric vehicles and switching to green energy suppliers; and the potential levers we can use to change the behaviours of individuals, corporations and governments.
