Rich Man, Poor Man: Body Language Can Indicate Socioeconomic Status, Study Shows

The results, reported in Psychological Science, reveal that nonverbal cues can give away a person's SES. Volunteers whose parents were from upper SES backgrounds displayed more disengagement-related behaviors compared to participants from lower SES backgrounds. In addition, when a separate group of observers were shown 60 second clips of the videos, they were able to correctly guess the participants' SES background, based on their body language.

The researchers note that this is the first study to show a relation between SES and social engagement behavior. They surmise that people from upper SES backgrounds who are wealthy and have access to prestigious institutions tend to be less dependent on others. "This lack of dependence among upper SES people is displayed in their nonverbal behaviors during social interactions," the psychologists conclude.
