Rationalization is a suboptimal defense mechanism associated with clinical and forensic problems

Area of Science:

• Psychology
• Forensic Psychology
• Clinical Psychology

Background:

• Rationalization is often considered a rational cognitive process.
• This perspective is challenged by evidence suggesting it may be a suboptimal defense mechanism.

Purpose of the Study:

• To evaluate the rationality of rationalization as a defense mechanism.
• To examine empirical evidence linking rationalization to psychological and behavioral outcomes.

Main Methods:

• Review of empirical clinical and forensic psychological evidence.
• Analysis of studies associating rationalization with developmental and behavioral issues.

Main Results:

• Rationalization is empirically supported as a suboptimal defense mechanism.
• A significant association exists between rationalization and poorer emotional development.
• Rationalization is linked to a spectrum of antisocial behaviors, including shoplifting, pedophilia, and murder.

Conclusions:

• Rationalization is not a rational defense mechanism.
• Its use is associated with negative psychological and behavioral consequences.
• Further research into the clinical and forensic implications of rationalization is warranted.
