Perceptual defense refers to the psychological tendency to overlook or rationalize information that is personally or culturally uncomfortable, thereby protecting one's worldview.
Step-by-step explanation:
The term that refers to a tendency to distort or ignore information that is either personally threatening or culturally unacceptable is perceptual defense. This psychological concept relates to how individuals protect themselves from information that may be unsettling or that contradicts their existing beliefs or cultural norms.
