According to a recent study, people who live in countries with diverse populations tend to smile more than those who live in more homogenous places.
People who come from more diverse countries tend to smile more and for different reasons, according to a new study.
It is thought that nonverbal forms of communication become more important when people with different languages and cultural norms have to interact.
Conversely, in countries with homogenous backgrounds, smiles communicating dominance are more prevalent since social hierarchies are well-established.
To arrive at these findings, the research team first scored countries’ levels of historical heterogeneity which reflects whether their populations came from few or numerous places over their previous 500-yea
