Study: Rich people are less likely to notice you

Like your cultural background, your socioeconomic status affects the way you think.

In a 2016 study published in the Association for Psychological Science, researchers at New York University claim that, compared to the working-class, the rich aren't as likely to notice or be interested in the people around them.

NYU doctoral student Pia Dietze and her co-author, psychologist Eric D. Knowles, came to that conclusion after performing a series of experiments on how members of different social classes feel about the "motivational relevance" of others, or "the degree to which others are seen as potentially rewarding, threatening or otherwise worth paying attention to."

"Across field, lab and online studies, our research documents that other humans are more likely to capture the attention of lower-class individuals than the attention of higher-class individuals," said Dietze in a press release, and as reported by Quartz.

For the first experiment the researchers had subjects roam New York City streets wearing Google Glass so they could record their visual fields. What the researchers found was that those who identified as upper-class looked at others on the street just about as frequently as those who said they were working-class, but the upper-class individuals did not hold their gaze on others for as long.

Smart glasses, however, only really measure the direction in which you're looking. So, to be more precise in the second experiment, the researchers used eye-tracking technology on subjects as they looked at photos of busy streets.

This time, those who identified as less wealthy spent more time looking at people in the photos, while the upper-class individuals were more likely to dwell on "things."

At this point the researchers had clearly defined a trend, but they still wanted to confirm whether the difference in behavior was a conscious choice. "It may be that class affects only deliberate aspects of attention — such that higher-class individuals consciously choose to devote less attention to other people than do lower-class individuals," they report. "Or social class may also influence spontaneous attentional processes that occur independently of voluntary control."

They explored the question using a "flicker paradigm," meaning they showed nearly 400 participants recruited online pairs of images that quickly alternated back and forth. The images were of everyday objects like plants and clothing, as well as human faces, and most pairs contained subtle differences. The goal of the participant was to identify those differences as quickly as possible.

As it turned out, when one of the objects was different in the two images, the upper- and working-class participants had similar reaction times. When it came to changes in faces, however, upper-class subjects were slower to detect them.

The differences, they concluded, were involuntary: "Social class affects information processing in a pervasive and spontaneous manner," Dietze said.

Previous research, as the authors note in the paper, has found that, compared to members of the upper class, members of the working class have a more interdependent and holistic social outlook. Along the same lines, working-class individuals have been found to more accurately judge others' emotions and feel more compassion for others' suffering.

This study now posits that the contrast "may have as much to do with attentional neglect as it does with reduced empathic ability."

"Our work contributes to a growing knowledge base around the influence of social class background on psychological functioning," says Dietze. "The more we know about the effect of social class differences, the better we can address widespread societal issues — this research is just one piece of the puzzle."
