Personality test methodology: scoring, frameworks and limits
Diahu uses a mix of public-domain instruments and original reflection tools. Their evidence, rights, scoring, and local readiness differ; each assessment page states which route it uses.
What we measure
We do not treat every popular framework as a validated scale. Each page identifies whether its items are public-domain, independently authored, licensed, or still blocked; what dimensions the current form covers; and whether the market has answerable local items or only a development-method page.
How a result is calculated
Scoring is rule-based and transparent, not a black-box guess. Your answers feed a defined set of dimensions with fixed weights, and those dimensions decide your result type. The same answers always produce the same result, and AI is used only to phrase the write-up — never to invent the score.
Norms and percentiles
Where a quiz reports a percentile, it compares your raw score against a reference sample for that assessment. A percentile tells you where you sit relative to others who took the same questions; it is a position, not a verdict.
What this is for — and not for
Diahu is for self-reflection and entertainment. It is not a medical device, not a diagnosis, and not treatment. If a result resonates, treat it as a prompt for thinking and conversation, and pair it with your own real-life context.
Your data
You can take any assessment without an account. We keep data collection minimal, never use your psychological answers for ad targeting, and let you choose what to save or share.
