The Short Version
The claim faithfully represents Kurt Danziger's central thesis that psychological categories are historically constructed and function performatively rather than as neutral descriptions of reality. Multiple authoritative sources — including his own "Naming the Mind" (1997) and peer-reviewed discussions of his work — confirm this position. However, the specific examples "low IQ," "gifted," and "normal" are not clearly documented as Danziger's own chosen illustrations; they appear mainly in secondary works applying his framework. The phrase "terms such as" softens this, but readers should note the examples are interpretive extensions, not verified direct attributions.
