rationalization

What Is Rationalisation?

Rationalisation is a self-deception defence mechanism where one reinterprets threatening motives as more acceptable ones. PDD examiners watch for rationalisation during the Pre-Test Interview because faulty test questions that empower self-deceit could produce false negative results. No research has formally evaluated its effects on PDD efficiency.

Significance in PDD

This concept is part of the theoretical and practical framework supporting psychophysiological detection of deception. Understanding it helps practitioners, researchers, and informed consumers appreciate the scientific foundations of modern polygraph testing and the ongoing refinement of techniques and methods based on empirical research.
