A significant limitation in personality psychology is that theories and assessments developed in Western societies may not be universally applicable. Cultural context is crucial, as concepts valid in one culture might not apply to others. For instance, studies have shown that the Eysenck Personality Inventory yields relevant results in a collectivist culture like Papua New Guinea only when analyzed within that specific cultural context. Similarly, personality assessments for groups like Native Americans can be biased if they don't account for culture-specific responses and tribal frames of reference, requiring assessors to have deep cultural knowledge to ensure accuracy.
