Why doesn’t everyone see the world the same way?

People often misinterpret their perceptions of people and situations as objective fact, rather than just their own interpretation.

UCLA psychologist Matthew Lieberman explains why people may see things differently.

Why are we so sure that the way we see people, circumstances, and politics is correct and that the way others see them is wrong?

According to a recent study by University of California, Los Angeles psychology professor Matthew Lieberman, the answer lies in a part of the brain he calls the “gestalt cortex,” which helps people make sense of ambiguous or incomplete information— and reject alternative interpretations. .

The study, which was based on an analysis of over 400 previous studies, was published in the journal Psychological Review.

People often mistake their perceptions of other individuals and events for an objective fact, rather than just their interpretation. People who experience this phenomenon of “naive realism” feel that they should have the last word on the world around them.

“We tend to have unreasonable confidence in our experiences of the world and see others as misinformed, lazy, unreasonable or biased when they fail to see the world as we do,” Lieberman said. “Evidence from neural data is clear that the gestalt cortex is central to how we construct our version of reality.”

He believes that the most overlooked cause of conflict and mistrust between people and organizations is naive realism.

“When others see the world differently than we do, it can serve as an existential threat to our contact with reality and often leads to anger and suspicion of others,” Lieberman said. “If we know how a person is seeing the world, their subsequent reactions are much more predictable.”

While the question of how people make sense of the world has been an enduring topic in social psychology, the underlying brain mechanisms have never been fully explained, Lieberman said.

Mental acts that are coherent, easy, and grounded in our experiences tend to occur in the gestalt cortex. For example, a person may see another person smiling and, without giving it any apparent thought, perceive that the other person is happy. Because these conclusions are immediate and effortless, they usually feel more like “seeing reality” — even though happiness is an internal psychological state — than like “thinking,” Lieberman said.

“We believe that we have simply witnessed things as they are, which makes it more difficult to evaluate, or even consider, other points of view,” he said. “The mind emphasizes its best answer and rejects rival solutions. The mind may initially process the world as a democracy where any alternative interpretation gets a vote, but it quickly ends up as an authoritarian regime where one interpretation rules with an iron fist and dissent is suppressed. In choosing one interpretation, the gestalt cortex literally inhibits others.

Previous research by Lieberman has shown that when people disagree face-to-face — about a political issue, for example — activity in their gestalt cortex is less similar than for people who agree with each other. (This conclusion was supported by a 2018 study in the journal

The gestalt cortex is located behind the ear, and it is situated between the parts of the brain responsible for processing vision, sound and touch; those parts are connected by a structure called the temporoparietal junction, which is part of the gestalt cortex. In the new study, Lieberman proposes that the temporoparietal junction is central to conscious experience and that it helps organize and integrate psychological features of situations that people see so they can make sense of them effortlessly.

The gestalt cortex isn’t the only area of the brain that enables people to quickly process and interpret what they see, he said, but it is an especially important one.

Using neurosurgical recordings to understand the “social brain”

In a separate study, published in April in the journal Nature Communications, Lieberman and colleagues addressed how, given our complex social worlds, we are able to socialize with relative ease.

Using the first mass-scale neurosurgical recordings of the “social brain,” Lieberman, UCLA psychology graduate student Kevin Tan and colleagues at Stanford University showed that humans have a specialized neural pathway for social thinking.

Lieberman, author of the bestselling book “Social: Why Our Brains Are Wired to Connect,” said humans are social by nature and have an exceptional capacity for assessing the mental states of others. That ability requires the brain to process a large number of inferences from a vast array of idiosyncratic cues. So why does that process often feel so effortless compared to simple tasks like basic arithmetic?

Clear answers have been elusive for those who study social neuroscience. One culprit could be scientists’ reliance on functional magnetic resonance imaging, which is effective at scanning where brain activity occurs, but less effective at capturing the timing of that activity.

Researchers employed a technique called electrocorticography to record brain activity at millisecond and millimeter scales using thousands of neurosurgical electrodes. They found that a neurocognitive pathway that extends from the back to the front of the brain is especially active in areas closer to the front when people think about the mental states of others.

Their findings suggest that the temporoparietal junction may create a fast, effortless understanding of other people’s mental states, and that another region, the dorsomedial prefrontal cortex, may be more involved in thinking things through more slowly and carefully.
