Evidence
How this platform is built, and how to check it
Every claim on this platform is either original PMA Science material, an observable procedure, or a statement about the state of the evidence. This section tells you which is which, and how we review it.
How we source and review
The sourcing standard, the review cycle, the rights rule, and what happens when we get something wrong.

What psychology can and cannot tell you
Six things that are well supported, and six that are routinely over-claimed.

Four commitments
- Original material only. We publish no reproduced questionnaire, item bank, coding manual, scoring system or certification content — ours or anybody else’s.
- Limits stated inside the resource. Not in a disclaimer at the bottom of a page. Every downloadable resource opens with a scope page that says what it will not do.
- No score, no threshold, no classification. Nothing here rates, screens, indicates or identifies any person or condition.
- Contested claims are marked as contested. Where the evidence is weak or disputed, we say so, even when the confident version would sell better.
The page that costs us money
The limits of facial inference exists because the commercial market around reading faces substantially over-states what the evidence supports. We would sell more by selling certainty. We are not going to.
Educational scope. Everything published on PMA Science Psychology is provided for education, study and professional documentation. Nothing here is a diagnostic instrument, a psychometric test, or a substitute for assessment, treatment, supervision or emergency care by a qualified professional.
