007 has a new way to determine your real background – how you express emotion. Turns out, facial expressions have accents. They vary based on your culture and where you were raised.
Science has long thought that six (or seven, depending on who you ask) emotions are expressed the same way universally – happy, surprise, fear, disgust, anger, and sad. However, new research has found that emotional expression varies by language and culture. So while most Westerners may express disgust by wrinkling their nose and flaring their nostrils, those from the East may express it differently – such as rapid eye movements.
Overall though, commonalities tend to outweigh differences in expressions.
