Policy learning and system change – devolution’s missed opportunity (so far)

It’s been a busy couple of months.

A few weeks ago, I was fortunate to get to speak at the University of Glasgow’s Centre for Public Policy conference. The theme of the conference was about what we need to stop doing and start doing in Scotland to deliver better policy outcomes. I spoke about why we need to start measuring what matters to inform better policymaking.

I have also been out and about with colleagues in recent weeks in Belfast, Edinburgh and Cardiff meeting policy stakeholders to discuss challenges and opportunities around embedding deliberative and participatory approaches into our parliaments. I’ll be in London for a similar meeting later in March.

In addition, Carnegie UK’s CEO, Sarah Davidson, recently gave evidence to the Scottish Parliament’s Finance and Public Administration Committee reflecting on the role of the Committee over this parliamentary term and the importance of this function continuing into the new session.

And finally, informed by all the point above, last week in the office (well on a Slack thread really) we were discussing and debating the various essential things needed to deliver systems change at government level. Spoiler alert: 1) it’s complex; 2) a lot of it is about fixing incentives and 3) yes, we really are that cool to be talking about that on a Friday.

In trying to get my head around all of this, it strikes me that there is a common thread that runs through much of these challenges and topics. Basically our governments and our legislatures are not well set up for reflection, analysis and review of how they work.

It’s all very well folk like me banging on about how the system needs to change, but does the system itself actually have the ability to learn, reflect and change?

The scrutiny gap

It’s a tricky question to answer and opinions on all sides can be hard to prove. However, one useful proxy for a state’s capacity to be genuinely reflective would be to examine its parliament’s use of post-legislative scrutiny. Sadly, doing so does not make for encouraging reading and it’s something that’s harder to get consistent data on than you might imagine.

On the numbers I was able to find, since devolution:

I want to note upfront that the numbers above may not be fully accurate. It turns out that due to the different ways in which this data is recorded across various official websites, it is trickier than I anticipated to accurately map the passing of Acts to the right parliamentary session. Similarly, there are not really consistent records across our legislatures of post-legislative scrutiny or inquiries undertaken. Which is all somewhat indicative of wider data collation challenges across our parliaments.

Nonetheless, even with these caveats and even if they are just indicative, these numbers generate a few compelling bits of insight:

When devolution was established across Scotland, Wales, and Northern Ireland, the ambition was for a new kind of politics – one that was more responsive and agile than the established Westminster model. Decades later, we have succeeded in becoming prolific lawmakers. But we have failed to build the policy feedback loops essential for a system that actually improves lives. We are really good at the ribbon-cutting of new legislation, yet we rarely return to the site to see if the building is still standing.

This might all seem very technocratic (and it is), but it matters.

If we do not know which Acts or policies actually work to improve people’s lives then we risk simply pulling more legislative levers in the hope that something eventually clicks.

Legislate less, deliberate more

The next phase of devolution, and the incoming session in Wales and Scotland, should be characterised by a shift in posture: legislate less and deliberate more. This might be seen as a hard sell if it is interpreted as politicians should “do less” but this is about getting more done that achieves better impact for people at scale.

To my mind there are three things needed to make this happen:

The devolution dividend

The dividend of devolution was never meant to be a higher volume of output on the statute book. It was meant to be a better quality of life for people in places.

After 25 years of devolution, Scotland, Wales and Northern Ireland have built remarkably productive legislatures, but not reflective ones. Across all three, only a tiny percentage of Acts ever receive formal post-legislative scrutiny. This scrutiny gap represents a missing feedback loop in our policymaking system. To deliver the original promise of devolution – improved wellbeing, not just more laws – the next parliamentary sessions must normalise post-legislative review, institutionalise deliberative democracy, and radically improve how nations share what works.

If we want our policy making to actually improve our lives and wellbeing then our parliaments must be brave enough to stop and ask: did that actually work? If our devolved policy systems cannot learn, then they will struggle to meaningfully improve.
