Response acquiescence can forge fake statistical links between unrelated measures

Evidence

Furthermore, researchers noted long ago that unbalanced scales usually correlate best with other unbalanced scales (Hyman and Sheatsley, 1954; Campbell, Siegman, and Rees, 1967)—or indeed with anything potentially affected by yea-saying, including single-item questions. Shared acquiescence could thus create a connection between any two things, no matter what they (supposedly) measure. — Bob Altemeyer, The Authoritarian Specter, 775

  • QUESTION: This is a foundational critique of survey methodology worth chasing further—how often do published correlations in personality/social psychology trace back to shared acquiescence rather than real construct overlap?
  • XREF: Connects to the general literature on invalid correlations/methodological artifacts—the ‘garbage in, garbage out’ problem in quantitative social science.
