Final answer:
The assertion that facial expressions displaying emotions are not consistent across the globe is false. Universal emotions with corresponding facial expressions have been identified through decades of research by Paul Ekman, indicating a biological basis rather than a cultural one for these expressions.
Step-by-step explanation:
The statement in the question - that facial expressions that display emotions differ according to culture across the globe - is false. Paul Ekman's research, including his fieldwork in New Guinea, shows that the ability to produce and recognize facial expressions of emotions is universal, transcending cultural boundaries. While cultural display rules may govern the appropriateness of showing certain emotions in different contexts, Ekman identified seven universal emotions, including happiness, surprise, sadness, fright, disgust, contempt, and anger, each associated with distinct facial expressions.
Ekman's conclusions are supported by the observation that even congenitally blind individuals, who have never seen facial expressions, produce similar expressions when experiencing these emotions. This suggests a biological basis for emotional expressions. Moreover, these findings are in line with Charles Darwin's earlier work, emphasizing the evolutionary perspective on the universality of facial expressions in expressing emotions.
