Research transparency

Evidence before certainty.

The Triad is a published conceptual framework and an exploratory public instrument. This page keeps those two things distinct.

Established

Published proposal

The conceptual framework, domain definitions, Developmental Expansion Index, applications, and validation agenda are publicly archived.

Operationalized

Transparent Prototype 05

The public questionnaire contains 30 items per domain, plus 12 separate Developmental Expansion items. When listening evidence is available, within-domain statement and listening weights are 80% and 20%; a domain uses statements alone if none of its audio tasks can be assessed. The magnitude index weights the DEI module at 75% and the mean of the three pre-share 1–5 domain scores at 25%.

Not established

Psychometric validity

The public score is not normed, diagnostic, a percentile, or evidence that the three-factor structure has been confirmed.

Required next

Empirical program

Expert review, pilot item analysis, behavioral comparison, reliability, factor testing, invariance, longitudinal study, and appropriate norms.

An evidence map—not borrowed certainty.
