Deconstructing, reconstructing, preserving Paul E. Meehl's legacy of construct validity.

Area of Science:

• Psychology
• Philosophy of Science

Background:

• Historical debate on explaining human behavior: physically existing factors vs. hypothetical constructs ('useful fictions').
• Influence of key thinkers: Jeremy Bentham, Hans Vaihinger, and Francis Galton.
• Examination of validity, measurement, and definition issues in psychological theories.

Purpose of the Study:

• To analyze the historical and philosophical underpinnings of cause-and-effect explanations in human behavior.
• To critically evaluate the role and validity of hypothetical constructs in psychological theories.
• To highlight the enduring impact of seminal works by MacCorquodale, Meehl, Cronbach, and Meehl.

Main Methods:

• Historical analysis of philosophical and psychological literature.
• Conceptual examination of theoretical constructs and their empirical grounding.
• Review of landmark studies and their influence on psychological theory construction.

Main Results:

• Distinction between empirically grounded and hypothetical explanations of behavior is historically contested.
• Hypothetical constructs present challenges in measurement and definition within psychoanalytic and trait theories.
• Seminal works by MacCorquodale & Meehl and Cronbach & Meehl remain central to the discussion.

Conclusions:

• The debate on the nature of explanatory entities in psychology continues to evolve.
• Careful consideration of hypothetical constructs is crucial for robust psychological theory development.
• The legacy of P. E. Meehl's contributions significantly shapes contemporary discussions in psychological science.
