Community Disorder: How Do We Prevent an Information Emergency?

Drawing on the August 2024 UK riots — triggered by algorithmically amplified disinformation about the Southport attack — this Demos report provides the most comprehensive analysis available of how an information emergency unfolds in a democratic society and what infrastructure failures enable it. The report maps the information supply chain failures that allowed disinformation to propagate from fringe channels to mainstream social media to real-world violence: platform demoderation, the absence of rapid rebuttal infrastructure, and the collapse of local media that would historically have provided accurate local information.

The August 2024 riots are the most important domestic case study of algorithmic amplification of disinformation in a UK context, and this report is the primary reference for that case. The proposed emergency response architecture — drawing on crisis communication frameworks from public health and emergency management — is the most operationally specific available recommendation for how the UK should build the rapid-response information infrastructure that the riots demonstrated is currently absent. For practitioners working on crisis communication, platform governance, and information emergency response, this report is essential reading.
