UK consumers retain purchase control when using AI shopping agents

ACI Worldwide · 22 June 2026

YouGov surveyed 2,080 UK adults for ACI Worldwide from 19 to 22 June 2026. 19% trusted AI to make everyday purchasing decisions under user-set rules, 69% did not, 70% said purchases made without asking would affect willingness to use an AI shopping agent, and 60% said one mistake would cause them to stop using one.

This is the observable fact the cited source supports, stated without interpretation.

Tests whether autonomous systems displace human interaction at transaction and decision stages.

Human-Bounded Interaction

Boundary evidence for HBI. Agentic discovery can expand while consumers retain approval over economically consequential decisions.

The fieldwork occurred after publication and directly measures willingness to delegate purchase authority.

This is the framework's reading of the fact above. The source does not endorse it and is not cited as doing so.

early signalanticipated boundary

Retained human control at consequential transaction points is an anticipated trust and control boundary. The monitor will track whether this persists or recedes as trusted delegation infrastructure develops.

Current evidence is recorded immediately. The paper's longer empirical horizon determines when persistence becomes a stronger framework-level test.

This is stated preference, not observed transaction behaviour. Better trust and payment controls may increase delegation over time.

Recorded for every observation assessed at strength 4 or 5. A record that cannot state the strongest competing reading of its own evidence is not published.

What would strengthen this evidence

Observed transaction data showing human confirmation remains common as agentic commerce scales.

What would weaken or falsify this interpretation

Large-scale autonomous purchasing without per-transaction approval.
