Polygraphs: erosion of the privacy right

Area of Science:

• Forensic Psychology
• Legal Studies
• Constitutional Law

Background:

• The polygraph, commonly known as a lie detector, is often oversimplified in its perceived danger and invasiveness.
• Its operation delves into private physiological responses, raising significant ethical and privacy concerns.

Purpose of the Study:

• To critically analyze the mechanics and theoretical underpinnings of polygraph technology.
• To evaluate the legal admissibility and practical application of polygraphs across various settings.
• To explore the profound human, social, and constitutional implications of polygraph usage, particularly concerning individual privacy.

Main Methods:

• Review of polygraph mechanics and theoretical basis.
• Analysis of legal precedents regarding polygraph admissibility.
• Examination of constitutional arguments against polygraph use.

Main Results:

• Polygraph use intrudes upon private physiological data.
• Reliability concerns exist, especially in personnel, business, and disciplinary settings.
• Constitutional arguments for restricting polygraph use, particularly in the private sector, are substantial.

Conclusions:

• The polygraph's invasive nature necessitates a thorough consideration of its human, social, and constitutional ramifications.
• Questionable reliability and significant privacy intrusions warrant a constitutional basis for restricting its use, especially in the private sector.
