TWENTIETH-CENTURY SYSTEMS · THREE PROVENANCES
Three modern maps, three different objects
MBTI begins from questionnaire choices. Human Design calculates a BodyGraph from birth data. Gene Keys turns part of that machinery into a contemplative sequence. Their proximity in time does not make them interchangeable.

What this page is for
Three modern maps, three different measurement problems.
Questionnaire preference, calculated BodyGraph, and contemplative sequence are not interchangeable merely because their communities share language.
Boundary: Cross-system resemblance should be tested at the level of variables and procedures, not vocabulary alone.

Comparison rule: map only the claim in front of you. A partial vocabulary match does not establish equivalence, inheritance, or predictive validity.
The Research Library keeps these papers beside the older traditions without calling them ancient.
