October 15, 2012 Enid Burns for redOrbit.com – Your Universe Online Smile, and the whole world smiles back at you.

A report presented at the annual Society for Neuroscience conference in New Orleans titled by Evan Carr, a graduate student at UC San Diego and one of the study’s authors, shows people tend to return the smile of someone they feel is in a station below them. Alternately, when someone feels powerless, they tend to return everyone’s smiles.
