Current
What we can say today
Lux has versioned scoring, defined report rules and source-bank internal-consistency evidence. These are documented foundations, not completed Lux-specific validation.
Lux evidence
Lux evidence: current foundations and an active programme
Lux is moving through an active, staged evidence-development programme. We publish what current evidence supports, state the limits, and strengthen claims only when pre-defined studies produce supporting results.
Current evidence status
Active
What we are studying
The evidence programme includes reliability, validity, fairness and utility questions, staged as suitable data and study designs become available.
Claim limit
What we do not claim
Lux is not clinically validated, diagnostic, predictive or a basis for personnel selection. Participant volume alone does not change those limits.
What we know
A documented starting point
The active programme combines ongoing testing of versioned scoring and committed fixtures with staged Lux-specific empirical evaluation. Technical checks make the scoring pathway more inspectable; they do not by themselves establish psychological reliability or validity.
The source/reference evidence and technical architecture are useful context, but neither should be mistaken for completed Lux-specific validation.
Technical source-bank detail
The full ten-item Big Five item banks have documented internal consistency of α .800–.898 in a 603,322-response source/reference dataset.
This is source/reference internal-consistency evidence, not a count of Lux participants and not proof that every Lux output is valid.
Lux also has an evidence-governance architecture: defined fields, versioned scoring, report eligibility and explicit claim limits. That makes the work more inspectable; it does not by itself establish psychological validity.
Evidence roadmap
A staged path, with status stated plainly.
No stage is treated as complete before its evidence supports that status.
Status: Current
Foundations documented
Versioned scoring, defined report rules, evidence boundaries and source/reference evidence provide an inspectable starting point.
Status: Active
Technical checks active
Ongoing checks of versioned scoring and committed fixtures make the scoring pathway more inspectable; they do not establish psychological reliability or validity.
Status: In progress / future, as described
Lux-specific empirical studies
Test–retest work is part of the active programme. Other staged studies proceed as suitable participant data and study designs become available.
Status: Future evidence gate
Stronger claims only after supporting results
Claims advance only when pre-defined studies produce results that support them, not when participation volume reaches a milestone.
Study questions and present claim limits
Test–retest reliability is part of the active evidence programme and will assess score stability as repeat-response data becomes available.
Staged studies will examine convergent and discriminant validity for proprietary Lux fields, representative norms, intended-population fairness and clinical utility as suitable data and study designs become available.
- Lux remains a descriptive assessment. It is not clinically validated, diagnostic, predictive or a basis for personnel selection.
- The programme is active, but it has not yet produced completed Lux-specific validation results.
How claims advance
Evidence grows by study, not volume alone
Eligible participant data enables pre-defined studies; participant volume alone does not establish validity, reliability, norms, fairness or clinical utility. Stronger public claims will follow only when study results support them.
Research and support
Help the evidence advance responsibly.
Research partners can help answer defined questions. Donors can support the staged work without overstating where it stands.
