What cash-strapped governments can learn from behavioural science’s big successes
Tomorrow the UK heads to the polls to choose their next government. In anticipation, Lucy Makinson, BIT’s Head of Policy, considers how an incoming government can deliver impact, even in the face of fiscal constraint.
If the Conservatives and Labour have agreed on one thing this election, it’s that money is tight. UK government borrowing is the highest it has been since the Second World War, and any incoming government will have to work hard to balance the books. This can make it feel like the parties are hamstrung, constrained to middle-of-the-road policies because the finances don’t allow for anything more exciting.
But no money doesn’t have to mean no ideas. BIT (the Behavioural Insights Team) was set up with a sunset clause: make 10x your cost in government savings, or get shut down after two years. The project that delivered the biggest savings early on (tax payments) also won us the Civil Service Innovation award. Good ideas don’t have to blow the budget.
Over the last 15 years, as behavioural science has spread globally, the methods and impact have evolved far beyond those early successes. And almost always at low cost.
So what can three successes from our behavioural science work teach a new government about delivering impact from tight coffers?
Almost all UK employees are now automatically enrolled into their employer pension scheme, following measures introduced in 2012. Saving rates have skyrocketed: over 90% of employees now save for a pension, either with their employer or separately. The biggest impact has been on the most vulnerable. Before auto-enrolment, just 22% of the most financially vulnerable were saving for a pension. Now 90% are – almost indistinguishable from higher earners.
In a public policy rarity, the programme was cheaper and more successful than anticipated.
Seemingly small frictions (such as needing to opt-in or sign–up to a programme) can have disproportionate negative impact. The greatest harm is to the most vulnerable, who are more likely to be time poor, and less likely to have the resources to navigate complex systems.
Yet automatic enrolment was a rare success – too many government schemes are still marred by complexity, excluding the very people they aim to help.
Introduce auto-enrolment for key benefits, including childcare subsidies and Free School Meals status
Measure government ‘sludge’, and make tackling it a key priority
Extend pension pots to rainy-day savings
It is much easier to eat healthily when we have healthy options in front of us, rather than needing to constantly restrict our own behaviour. With this in mind, the Soft Drinks Industry Levy (SDIL) or ‘Sugar Tax’ was designed to encourage drinks’ producers to reformulate their products with less sugar.
By 2019, four years after the levy was announced, the sugar content of eligible drinks had fallen by 44%. Recent studies suggest the Sugar Tax is already reducing childhood obesity and tooth extractions, and the Institute for Government says the policy has a “rare status as a win-win policy for both public health and industry”. Far from costing money, the Sugar Tax generated £355m of government revenue in 2022/23.
Our behaviour is strongly shaped by our environment. Approaches which help to shape markets deliver disproportionate impact, far beyond just health.
Introduce supermarket nutrition targets
Require job adverts to publish pay ranges
Develop quality metrics for key markets
In one of BIT’s earliest trials, we worked with job centres in Essex to redesign meetings between job coaches and job seekers. This included massively streamlined paperwork in the first session, so that they could focus on building rapport; shifting the focus for subsequent meetings onto the week ahead, not the week passed; and incorporating goal-setting and motivational activities.
Job seekers who received the new support were 3% more likely to find jobs quickly. Across the UK, that would equate to about 50-100m fewer days spent on benefits each year.
A side benefit of the work with job centres was that job centre staff were also better off: they were nearly twice as likely to say they were happy at work, 30% more likely to feel their job was worthwhile, and reported lower anxiety. With retention crises across the public sector, understanding what motivates staff – as well as service users – is critical.
Stress and poverty often exacerbate our behavioural biases, so behavioural design matters even more when designing systems for the most vulnerable. Yet there is still low-hanging fruit in how these systems are designed.
Give universal credit (UC) claimants more choice over how their payments are disbursed (extend ‘Scottish Choices’)
Measure and reward rapport with job coaches (and wider public services)
There’s no denying that fiscal pressures pose a significant challenge for any incoming government, with numerous areas crying out for increased investment. However, this financial constraint makes it even more crucial to seize low-cost, high-impact opportunities where they exist.
The examples and proposals outlined here demonstrate that effective governance isn’t always about massive spending. Rather, it’s about smarter delivery – achieved through a keen understanding of how citizens interact with services and respond to their environment. While that may not be the catchiest campaign slogan, we should hope that once the election dust settles, there’s a genuine appetite for evidence-based effectiveness in policy making.
