- Jung's psychological types (1921)
What this is
Jung's ideas in Psychological Types (1921) are used, not his text; the four-letter instrument built on it is a trademark with copyrighted items and none of it is reproduced here. These are original items on the eight functions, each scored on its own 1–100 rather than forced against its opposite — so the code at the top is derived from your stack, not asked for directly. Treat the code as shorthand. The stack is the claim.
Where it comes from
written down, not impliedJung's psychological types (1921)
Jung set out the psychological types in 1921; his ideas are used here, not his text. The four-letter code here is derived from the function stack rather than asked for; the MBTI's trademarked items are not used.

Why these questions carry no evidence
Every questionnaire in this app writes its own items, because the framework behind an instrument is usually public while the published questionnaire is copyrighted. That is the honest way to build it and it has a cost worth stating plainly: reliability and validity belong to a specific set of questions given to a specific group of people, not to the name of the idea behind them. These questions have never been given to a sample, have no norms, and have no evidence that they measure what they are named after.
