We recently wrote a blog on a recent study that finds that an individual’s use of facial expressions, such as smiles, is related to the migratory history of where they’re from. More specifically, the recent research suggests that if you come from a country of immigrants, you’re more likely to crack a friendly smile on the street.
A recent Science Podcast highlighted this research in their May 8 show. You can listen to the podcast in it’s entirety here. Fast forward to 6:45 to listen to the research on smiles!
