Preliminary Evidence That Lonely People Lose the Reflex to Mimic Other People’s Smiles, Potentially Sustaining Their Isolation
The findings suggest that a failure to mimic other people’s smiles automatically could be playing a role in loneliness. A failure to mimic a smile might send an antisocial signal to others, the researchers note, undermining social connections, and leading to social disconnect. “Indeed, this could be one behavioral mechanism that maintains chronic loneliness,” they add. This is a small study, and it can’t speak to the causal direction: does loneliness lead to a problem with smile mimicry or is it the other way around? But it does suggest a new target for addressing loneliness, and for further research into the role it might potentially play in real-world encounters.
