The old general warrant was hated because it searched broadly first and justified later. The digital cognitive version searches a database of curiosity first and identifies people later. The form is more technical, but the danger is recognizable: suspicion is distributed across a population before it is individualized.
Reverse-keyword warrants show the risk most clearly. They may be sought for serious crimes, and courts may sometimes admit evidence. But the method should still be treated as a high-risk exception because it treats a term, phrase, or address as the first suspect.
The danger is the merger of observation, inference, scoring, and consequence.
Cognitive proximity is not culpability
Physical proximity to a crime scene does not prove guilt. Cognitive proximity to a search term proves even less. A person can search the same phrase as a wrongdoer for fear, scholarship, neighborhood concern, legal advice, journalism, coincidence, or curiosity.
The more ordinary AI assistants become, the broader the problem becomes. Prompts can reveal drafts, fears, research questions, role-play, legal hypotheticals, medical concerns, political doubts, and symbolic exploration. Treating prompt similarity as suspicion converts the mind’s scratchpad into a lineup.

Minimum safeguards
The highest safeguard is refusal: do not use cognitive dragnets. If a jurisdiction allows them, the minimum standard should include strict necessity, narrow time windows, independent adversarial review where possible, minimization, notice after risk passes, suppression for overbroad use, transparency reporting, and bans on fishing for political, religious, medical, or journalistic curiosity.
The Cognitive Liberty position is simpler: search histories and prompts are not ordinary business records. They are compressed traces of the inner forum and require heightened protection.
