Phroneme
Public evidence status

What exists, what does not, and what every public claim rests on.

Phroneme currently has external evidence, internal drafts, and product demonstrations. It does not yet have a Phroneme participant dataset, psychometric validation results, population norms, a preregistered confirmatory study, or an independent replication.

Current scientific boundary

Cognitive autonomy is a proposed multidimensional construct, not an established diagnosis, intelligence score, or measure of human worth. Its reliability, validity, fairness, and sensitivity to change have not yet been empirically established.

These records govern the material claims retained after the first repository audit. Approval means approved for the qualified wording shown here. It does not mean peer review, institutional approval, or validation of the CAI.

EXT-KOSMYNA-2025-001
External Preprint

In a 54-person preprint, the LLM-assisted group showed the weakest EEG connectivity of three tool conditions and struggled to quote its own work. The study does not establish long-term causal harm or population-wide effects.

Known limitations

Preprint, small and task-specific sample, only 18 participants completed session 4, and the design does not establish population-wide or long-term causal effects.

Approved 2026-07-17; review by 2026-10-17
Known limitations

Healthy volunteers typed memorized sentences in a costly MEG system; the v2 dataset is embargoed until journal publication and the result is not ready for routine clinical use.
