The top reason is privacy and security, not confusion. Just 6% of those cutting back say they feel unprepared to use the technology.
A survey of 2,055 UK adults for King’s Digital Futures Institute and Responsible AI UK finds that 42% deliberately limit how much AI they use; 46% say they don’t, and 12% don’t know.1 Use is common — 46% use tools such as ChatGPT, Claude, Gemini or Copilot weekly, and 32% don’t use AI at all1 — so pulling back is mostly a choice, not a gap left by people without access.
Limiters were asked to pick the single most important reason. Privacy, security and compliance concerns led by a wide margin, ahead of a simple preference to keep working the way they already do.1
Gen Z use AI more regularly than Millennials or Boomers, and 93% call themselves “very” or “fairly” confident using it — yet they are the age group most likely to limit their use.1 Confidence and comfort aren’t the same thing: even among daily AI users, more than a third still say it carries more risk than benefit.1
The pattern holds economy-wide. Between October 2023 and June 2026, the share of adults who see more risk than benefit rose 4 points, 48% to 52%, while those seeing more benefit than risk fell 4 points, 38% to 34%.1 Belief in personal benefit moved both ways at once — agreement rose 6 points (32% to 38%) but disagreement rose faster, 8 points (19% to 27%) — a drift away from the middle, not a swing to one side.1
This is the survey’s initial data release; the full academic paper and open dataset are still pending, so the 42% figure has not yet been independently replicated by a second UK survey using the same question. “Limiting” use is self-reported and self-defined — the survey doesn’t measure actual usage logs, and given 70% of adults think avoiding AI exposure entirely would be difficult or impossible, some self-reported “limiters” may still be using AI-embedded tools without registering it as AI use. The reasons question forced a single “most important” choice, which likely understates how often privacy and habit act together. The Oct 2023 comparison point comes from a differently-commissioned survey (the government’s Centre for Data Ethics and Innovation) using the same pollster and question wording, which supports the comparison but isn’t a like-for-like replication.1
