The Short Version
No credible, independently verifiable source confirms that Kurt Danziger published a work in 1977 arguing that psychological concepts are constructed through measurement practices. Every high-authority source attributes this thesis to his 1990 book "Constructing the Subject." The only reference to 1977 comes from unverifiable background knowledge that vaguely mentions "articles in the 1970s" without a concrete title, journal, or citation. The specific date attribution is unsubstantiated.
