Feeling lonely can make us self-centered, and vice-versa

Feeling lonely can make us self-centered, research shows, and the reverse is also true, though to a less extent.

“If you get more self-centered, you run the risk of staying locked in to feeling socially isolated…”

The findings suggest a positive feedback loop between the two traits: As increased loneliness heightens self-centeredness, the latter then contributes further to enhanced loneliness.

“If you get more self-centered, you run the risk of staying locked in to feeling socially isolated,” says John Cacioppo, a psychology professor at the University of Chicago and director of the Center for Cognitive and Social Neuroscience.

The researchers write that “targeting self-centeredness as part of an intervention to lessen loneliness may help break a positive feedback loop that maintains or worsens loneliness over time.” Their study is the first to test a prediction from John Cacioppo and coauthor Stephanie Cacioppo’s evolutionary theory that loneliness increases self-centeredness.

This kind of research is important because, as many studies have shown, lonely people are more susceptible to a variety of physical and mental health problems as well as higher mortality rates than their non-lonely counterparts.

The outcome that loneliness increases self-centeredness was expected, but the data showing that self-centeredness also affected loneliness were a surprise, says Stephanie Cacioppo, assistant professor of psychiatry and behavioral science at the Pritzker School of Medicine.

Not alone in feeling lonely

In previous research, the Cacioppos reviewed the rates of loneliness in young to older adults across the globe. Five to 10 percent of this population complained of feeling lonely constantly, frequently, or all the time. Another 30 to 40 percent complained of feeling lonely constantly.

Their latest findings are based on 11 years of data taken from 2002 to 2013 as part of the Chicago Health, Aging, and Social Relations Study of middle-aged and older Hispanic, African-American, and Caucasian men and women. The study’s random sample consisted of 229 individuals who ranged from 50 to 68 years of age at the start of the study. They were a diverse sample of randomly selected individuals drawn from the general population who varied in age, gender, ethnicity, and socioeconomic status.

Early psychological research treated loneliness as an anomalous or temporary feeling of distress that had no redeeming value or adaptive purpose. “None of that could be further from the truth,” Stephanie Cacioppo says.

The evolutionary perspective is why. In 2006, John Cacioppo and colleagues proposed an evolutionary interpretation of loneliness based on a neuroscientific or biological approach.

In this view, evolution has shaped the brain to incline humans toward certain emotions, thoughts, and behavior. “A variety of biological mechanisms have evolved that capitalize on aversive signals to motivate us to act in ways that are essential for our reproduction or survival,” the coauthors write. From that perspective, loneliness serves as the psychological counterpart of physical pain.

“Physical pain is an aversive signal that alerts us of potential tissue damage and motivates us to take care of our physical body,” the researchers write. Loneliness, meanwhile, is part of a warning system that motivates people to repair or replace their deficient social relationships.

Evolution and loneliness

The finding that loneliness tends to increase self-centeredness fits the evolutionary interpretation of loneliness. From an evolutionary-biological viewpoint, people have to be concerned with their own interests. The pressures of modern society, however, are significantly different from those that prevailed when loneliness evolved in the human species, researchers found.

“Humans evolved to become such a powerful species, in large part due to mutual aid and protection and the changes in the brain that proved adaptive in social interactions,” John Cacioppo says. “When we don’t have mutual aid and protection, we are more likely to become focused on our own interests and welfare. That is, we become more self-centered.”

In modern society, becoming more self-centered protects lonely people in the short term but not the long term. That’s because the harmful effects of loneliness accrue over time to reduce a person’s health and well-being.

“This evolutionarily adaptive response may have helped people survive in ancient times, but in contemporary society may well make it harder for people to get out of feelings of loneliness,” John Cacioppo says.

When humans are at their best, they provide mutual aid and protection, Stephanie Cacioppo adds. “It isn’t that one individual is sacrificial to the other. It’s that together they do more than the sum of the parts. Loneliness undercuts that focus and really makes you focus on only your interests at the expense of others.”

The Cacioppos have multiple loneliness studies in progress that address its social, behavioral, neural, hormonal, genetic, cellular, and molecular aspects, as well as interventions.

“Now that we know loneliness is damaging and contributing to the misery and health care costs of America, how do we reduce it?” John Cacioppo asks.
