Understanding these cultural differences can foster greater cross-cultural tolerance and understanding.
A recent study published in Psychological Science found that people from different cultures respond differently to thoughts of death. European-Americans tend to focus on protecting their sense of self, leading to harsher judgments towards those perceived as threats. In contrast, Asian-Americans are more likely to reach out to others an...
