Question

Quizplus · Accepted Answer

Cross-cultural comparisons of personality traits can be misleading because people in each country rate themselves based on the people they know. This means that cultural differences in how familiar people are with certain personality traits can affect how they rate themselves and can skew the results of cross-cultural comparisons.

Answer: D 
 Another reason why cross-cultural comparisons of personality traits can be misleading is that cultures vary genetically as well as socially. This means that certain personality traits might be more common in certain cultures due to genetic factors rather than socialization, which can make it difficult to accurately compare personality traits across cultures.
