The "Hawthorne effect"--what did the original Hawthorne studies actually show?

Area of Science:

• Social Sciences
• Psychology
• Intervention Studies

Background:

• The Hawthorne effect is frequently cited to explain positive intervention study results.
• It encompasses various phenomena like observer awareness, compliance due to attention, and stimulus response.
• The term is sometimes equated to the social placebo effect.

Purpose of the Study:

• To critically evaluate the use of the "Hawthorne effect" in social research.
• To advocate for a more precise approach in explaining intervention outcomes.

Main Methods:

• Literature review of critical analyses on the Hawthorne effect.
• Analysis of the ambiguity and disputable nature of the term in research.

Main Results:

• Extensive critical literature suggests avoiding the general term "Hawthorne effect".
• The term is broadly applied, covering confounding variables, observer effects, and participant compliance.
• Its application is often ambiguous and disputable in evaluating intervention effectiveness.

Conclusions:

• Researchers should avoid the ambiguous "Hawthorne effect" in social research.
• Instead, specific, unmonitored psychological and social variables influencing outcomes should be identified and discussed.
• This promotes a more rigorous and transparent evaluation of intervention effectiveness.
