Rigorous research for a stronger movement

We believe good research makes everyone in the movement stronger. That’s why we run large-scale experiments, partner with academics, and work closely with campaigners to understand what really moves the dial.

In 2024, we ran the largest political Randomised Control Trial in UK history, tested hyperlocal messaging at scale, and used AI to analyse how people talk about politics online – producing insights that helped shape campaign strategy across the ecosystem.

Our research is designed to be practical and shareable. Whether it’s testing new tactics or exploring how new tech can be used ethically, our goal is simple: generate evidence that helps campaigners win – and share what we learn, so no one has to start from scratch.

Executive Summary This report details the findings of a Randomized Controlled Trial (RCT) conducted during the Leamington Clarendon local by-election. The study sought to test whether presenting Labour-likely voters with specific, ward-level local issues (such as pothole repairs and planning permissions) would increase voter turnout. Despite a small-scale yet well-executed deployment, the intervention yielded no […]

Last month, we had the pleasure of hosting Dr. James Ackland, a postdoc from the University of Glasgow’s Geospatial Data Science Group, who shared fascinating insights into how where we live influences how we vote. If you’ve ever wondered why polling can be spot-on in some areas but wildly off in others, this session offered […]

At the final Campaign Lab Academic Series of 2025, we heard from Dr Katrina Lawall from the University of Reading. We often hear talk about helping support women entering office, but there is a problem that gets far less attention than recruitment: retention. Even where parties and civil society have made progress encouraging women to […]

This test examined how different peer-to-peer (P2P) SMS message framings affect member engagement during a time-sensitive Get-Out-The-Vote (GOTV) effort for an internal organisational vote. The core challenge was to identify whether more informational or narrative-driven messages could outperform a simple reminder in prompting members to respond and confirm participation before the voting deadline.
This pilot study explored whether living next to visible campaign materials, specifically garden stakes, affect voter turnout during elections. The underlying hypothesis was that visible signs of community political support might influence civic behaviour by fostering social norms around participation, signalling local engagement, or encouraging individuals to vote when they see that others nearby are politically active.

Campaigners often assume that people are more likely to be persuaded by someone who looks or sounds like them, someone of a similar age, gender, or background. After all, research has long shown that we tend to trust people who seem “like us.” But a new study challenges that assumption head-on. In their paper, Shared […]

In the tenth edition of the Campaign Lab Academic Series, Isolde Hegemann, a PhD researcher at the London School of Economics, presented early findings from a major new study examining how Republicans in the United States respond to different forms of fact-checking. Her work comes at a moment when the American information environment has shifted […]

The ninth entry of our Academic Series asked a deceptively simple question: how did Labour secure one of the largest post-war majorities in 2024 while winning a historically low share of the vote for a governing party? Professor Charles Pattie walked us through the mechanics of First Past the Post (FPTP) to explain why this […]
