Public claim rule
Logos may describe optional study-session controls, historical inspiration, and evidence boundaries. It should not promise medical, cognitive, grade, memory, or guaranteed learning outcomes.
Evidence and citations
Evidence belongs beside the claim, not hidden behind it.
Logos can use real history, controlled findings, and practical product hypotheses while keeping unsupported outcomes out of public copy.
Apple-safe posture
Keep silence and user-selected settings available. Present listening filters as optional controls, not treatment, diagnosis, correction, or validated prescriptions.
Citation-backed topics
Five public evidence boundaries.
Each topic separates what the cited evidence can support from what Logos must not claim.
Controlled evidence
Auditory Laterality
Safe wording
Research often finds a right-ear advantage in competing-speech experiments. Logos turns that idea into an optional listening control, not a guaranteed learning result.
Boundary
The strongest evidence comes from dichotic-listening speech tasks. It does not validate a fixed music balance, a natural 70/30 brain ratio, focus gains, memory gains, grades, or learning speed.

Disputed efficacy
Tomatis History
Safe wording
Alfred Tomatis developed an influential listening method. Logos uses that history as inspiration for an optional filter; it does not provide the Tomatis Method or promise treatment or learning outcomes.
Boundary
History and influence are real. Broad treatment, language, memory, creativity, or academic outcome claims remain disputed and require stronger evidence.

Systematic review
Baroque Study Audio
Safe wording
Research finds small average background-music effects with large context differences. Logos offers instrumental Baroque audio as an optional study environment, not a guaranteed learning boost.
Boundary
Small average or subgroup findings do not prove a uniquely Baroque mechanism, a universal 60-BPM rule, or benefits for every learner and task.

Disputed historical method
Suggestopedia And Superlearning
Safe wording
Suggestopedia is a historically important learning method built from music, relaxation, expectation, teacher performance, and practice. Logos borrows the safer idea of a calm optional study ritual, not guaranteed accelerated learning.
Boundary
Suggestopedia was a multi-component classroom method. It does not prove that an app audio setting unlocks hidden reserves, subconscious memory, intelligence, grades, or accelerated learning.

Product hypothesis
Focus-Session Design
Safe wording
Logos tests practical focus-session structures: start, focus, pause, reflect, and choose whether to return. It measures completion and voluntary return, not grades or cognitive improvement.
Boundary
The best session length, break rhythm, reminder pattern, and reflection style vary by person, task, and context. App retention is not learning efficacy.

Questions skeptics ask
Does this evidence prove Logos improves learning?
No. These pages support bounded wording and design decisions. They do not prove app-level effects on grades, memory, intelligence, or learning speed.
Why include historical systems if evidence is mixed?
History can explain where an idea came from and which claims to avoid. Historical influence is not the same thing as validated product efficacy.
What can Logos measure first?
Logos can measure session start, completion, voluntary return, preference, and selected settings. Those metrics guide product design but are not proof of learning outcomes.
