Clio Research: AI Reduces Cognitive Load 25% — But Only If Firms Protect Non-Billable Time

Clio's UK & Ireland Legal Insights Report, featured in a Legal Support Network piece published July 6, finds that AI can reduce overall cognitive load by up to 25% — particularly in billing and document review — and that lawyers using AI tools log on average 2.9 billable hours out of an 8-hour day, leaving 5.1 hours unbilled. The key finding for wellbeing officers is not the efficiency gain but the explicit caveat: AI efficiencies do not automatically improve work-life balance, and the greatest benefits only materialize when AI simultaneously enables more work and reduces after-hours catch-up. If firms use AI gains purely to increase matter throughput, the technology transfers attorney capacity into additional output rather than restored recovery time. Wellbeing-conscious firms will need to pair AI deployment with explicit policy commitments — hours floors, after-hours email norms, on-call expectations — that prevent capacity gains from becoming invisible workload additions.
