Evidence system
Evidence Framework
The Evidence Framework explains how The Sciences classifies evidence strength, transparency, relevance, limitations and public claim language.
Evidence quality
Strength of support
Evidence may include peer-reviewed research, independent tests, systematic reviews, technical documentation, expert review and transparent operational data.
Relevance
Fit between evidence and claim
A strong study does not automatically support every marketing claim. The framework checks whether the evidence matches the product, population, setting and wording.
Limitations
Visible constraints
The Sciences encourages clear disclosure of limits, uncertainty, conflicts, methodology gaps and areas where evidence remains preliminary.
Proportionate wording
Public claims should not overstate causality, certainty, clinical effect, safety, generalizability or regulatory status.
Practical classification
Records may use internal evidence tiers to distinguish preliminary, supported, independently tested, externally validated and continuously monitored claims.
