Devices can now log ‘P300’ attention spikes, creating auditable records showing whether users actually engaged with key terms. Prominence disputes, they suggest, may become ‘largely academic’.

The authors warn regulators and developers alike: without guardrails, manipulative design may become normalised. Consent may soon be measurable—but also more easily engineered.
