Which defense mechanism is described as justifying unacceptable behavior with rational explanations?

• A. Projection
• B. Rationalization
• C. Displacement
• D. Reaction formation

Answer: (D)

Rationalization is the defense mechanism described as justifying unacceptable behavior with logical-sounding explanations. It lets a person defend actions by offering reasons that seem reasonable, helping to avoid uncomfortable guilt or self-criticism. For example, someone might claim a mistake was acceptable because “everyone does it” or that a misdeed happened because of external pressures, even if the real motive isn’t fully stated.

In contrast, projection involves attributing one’s own unacceptable thoughts to someone else, displacement shifts emotions to a safer target, and reaction formation expresses the opposite of an impulse to hide the true feeling. The described scenario matches rationalization because the emphasis is on giving rational-sounding excuses to justify behavior that’s not acceptable.
