[Uneasiness with facet analysis: time for a reappraisal]

Area of Science:

• Psychology
• Methodology

Context:

• Facet analysis, despite its age, faces resistance in psychology.
• It is often misconstrued as a research method or theory rather than a logical principle.

Purpose:

• To outline facet analysis and explain the reasons for its limited adoption in psychology.
• To clarify its nature as a logical principle of thought.

Summary:

• Facet analysis is a logical principle, not a narrow research method or theory.
• It is successfully applied in experimental psychology via multifactorial experimental designs.
• Its limited use in differential and diagnostic psychology stems from ignoring construct differentiation validity and rejecting factor analytic methods.

Impact:

• Highlights the overlooked contribution of facet analysis to measurement validity.
• Suggests potential for wider application in psychological research, particularly in differential and diagnostic contexts.
• Advocates for recognizing facet analysis as a foundational logical principle for robust psychological measurement.
