In Simple Terms
Researchers watched people view videos of someone being embarrassed or put down, and measured how their brains responded. People with higher scores on narcissistic traits showed less similar brain activity to one another than people with lower scores. That does not mean they lack empathy or that the study can diagnose anyone; it shows only that their responses to these social scenes varied more.
A Social Scene, Not a Still Image
A team of researchers at Aalto University in Finland studied brain activity as people watched filmed social interactions. The work was part of a multi-university project called Faces of Narcissism. The findings appeared in Cerebral Cortex on 1 October 2026, in a paper titled “Reduced Inter-Brain Coupling Among Observers of Threats to Others’ Self-Image in Narcissism.”
The researchers began with a methodological concern: many earlier tests relied on brief, limited cues, such as a picture of a sad face or a simple signal associated with pain. But relationships do not usually unfold as a series of disconnected images. They develop through words, context, and tone, and the same remark can mean different things depending on what came before. The team therefore designed an experiment using scenes that resembled fuller social interactions rather than isolated emotional cues.
Fifty-eight people took part in the brain scans after an initial screening of nearly 1000 adults. The researchers divided them into two groups according to their scores on measures of grandiose narcissistic traits: 28 people had high scores, and 30 had low scores. Such traits exist along a spectrum. A high score on a research measure is not, by itself, a clinical diagnosis of a personality disorder.
While inside the scanner, participants watched clips of actors having relatively natural-sounding conversations. One person told a personal story about either being socially excluded or receiving admiration from others. After the story, another person responded with criticism that challenged the storyteller’s standing or public image. For example, the critic might question whether the storyteller deserved the admiration they had received or blame them alone for being rejected in the past.
The viewers were not asked to take a particular side, and they were not given direct instructions such as imagining how the storyteller felt or trying to comfort them. That allowed the researchers to observe brain activity as participants followed the scene without prompting them to produce a specific empathic response. The distinction matters: the experiment examined how people process a social situation spontaneously, not how they respond when they already know what reaction is expected of them.
What Does It Mean for Brains to Respond Similarly?
The researchers were not suggesting that everyone’s brain produces an identical response, or that brain scans can read a specific thought. Instead, they used a measure called intersubject correlation, which compares changes in brain activity across viewers as they watch the same clip. If several people show a similar pattern over time, their neural responses can be described as more synchronized in that context.
That similarity does not prove that every participant felt the same emotion or interpreted the conversation in the same way. Nor does it reveal, on its own, what was going through anyone’s mind. It does, however, offer a way to assess how closely a group’s responses align while watching a shared scene. When people’s activity patterns differ, that may reflect differences in their attention, interpretation, or evaluation of the situation. Further research is needed to identify the precise reasons.
Among participants with lower scores, the researchers found a clearer alignment in brain responses when they watched the storyteller receive remarks that threatened their social image. Among those with higher scores, activity patterns were less consistent in specific brain regions. Put simply, members of the higher-scoring group did not show the same degree of similarity in their brain responses to the same social moment. Their responses varied more from one person to another.
Regions Involved in Understanding Context and Other People
The difference stood out in two regions: the dorsolateral prefrontal cortex, or dlPFC, and the posterior cingulate cortex, or PCC. These areas are associated with cognitive processes that include organizing thought, tracking context, and forming an understanding of other people’s perspectives and the meaning of their interactions. The researchers were interested that the difference appeared in networks involved in processing social meaning, rather than being evidence of a general difference in detecting sounds or images.
The team also examined the anterior insula, known as the aINS, which is involved in several processes related to internal sensations and responses to emotionally significant situations. However, the difference in synchronized activity in this region did not reach statistical significance. This is an important reason not to generalize the findings to every brain area associated with empathy: the clearest evidence concerned the dlPFC and PCC, while the result for the anterior insula was not statistically conclusive.
So the study does not suggest that a set of brain regions simply switches on or off, or that people with higher scores on these traits are unable to understand other people’s feelings. The narrower finding is that activity in some regions involved in thinking about social situations was less similar among members of the higher-scoring group as they watched another person face a social threat. Several explanations could account for this variation, including differences in what viewers noticed, how they read the speaker’s tone, or what judgment they made about the storyteller.
Why Focus on Protecting a Social Image?
The experiment drew on the idea of “face-work,” associated with sociologist Erving Goffman in the 1950s. Here, “face” does not mean a person’s physical features. It means the social image someone hopes to maintain in front of others: being seen as worthy of respect, acceptance, or admiration. In everyday life, people consciously or unconsciously help preserve this image during conversation, and may try to repair it if they are embarrassed or their image is undermined.
This idea helps explain why the researchers chose scenes involving recognition or rejection, followed by remarks that put the storyteller on the defensive. The experiment was not simply showing viewers a sad person. It presented a moment when the balance of a conversation shifted and someone’s standing was challenged in front of both a conversation partner and an audience. A viewer might feel embarrassed on the storyteller’s behalf, think the criticism was fair, find it harsh, or focus on other parts of the exchange. The possibility of all these different interpretations is what makes social context more complex than a single facial expression.
This relatively naturalistic approach adds an important dimension to personality research: traits may show up in how someone responds to events with social meaning, not just in their answers to a questionnaire. But videos cannot recreate everyday life in full. This remained a controlled experiment, with selected situations, actors, and short scenes. It did not cover every kind of relationship or all the circumstances that shape real-world interactions.
What the Findings Can—and Cannot—Tell Us
The researchers suggest that less similar responses may help explain one aspect of communication difficulties observed in some people with high scores on narcissistic traits. If members of a group interpret a social situation in more varied ways, misunderstandings or mismatched reactions may become more likely. But the study did not track participants’ real-life relationships over time, and it did not show that this neural pattern alone causes relationship problems or inevitably leads to breakups.
Most importantly, empathy is not a single thing. Feeling another person’s pain is different from working out what they may be thinking or understanding why they acted as they did. Both are also different from choosing to offer support. This experiment focused more on the alignment of responses related to processing social meaning and considering another person’s perspective. It would therefore be misleading to reduce the findings to a broad claim that participants “do not feel empathy.”
The sample of 58 participants—28 in the high-trait group and 30 in the low-trait group—allowed the researchers to examine brain activity in depth inside the scanner, but it cannot make the results a verdict on everyone. Participants were selected from an initial pool of nearly 1000 adults, yet the final research sample was still limited compared with the full range of personality traits and social situations. And comparing people at the two ends of the score range does not mean society is actually divided into two distinct types. Personality traits vary by degree, and behavior can depend on both the person and the situation.
The results also cannot identify the correct explanation for each participant’s internal response. Some viewers may have focused on the speaker’s authority or whether the criticism was fair; others may have paid more attention to the storyteller’s embarrassment or the details of the earlier story. Experience, mood, attention, and other factors may also shape responses, and these cannot be reduced to a single personality trait. The findings are therefore a starting point for understanding how traits may relate to patterns of social processing—not a tool for labeling people or reading their intentions.
Toward Experiments That Feel More Like Everyday Life
The study’s value lies in combining brain measurements with a social scene involving several people, while allowing participants to watch without being told how they should feel. A design that captures more of the details of an interaction may reveal differences that do not show up when someone sees a single face for a few seconds or is asked to judge a simple cue. Following a complete clip also makes it possible to relate brain activity to the unfolding story and responses, rather than to an isolated moment alone.
Even so, brain imaging cannot explain social behavior on its own. Activity in a particular region cannot be equated with a specific feeling, and less similarity between participants does not mean an absence of empathy. The measure captures how closely response patterns align across a group, while each individual’s brain activity follows its own course. To understand what lies behind the pattern, future studies could combine imaging with behavioral measures, ask participants how they interpreted the scene, and track their interactions in a wider variety of situations.
The scenes in this study also examined one specific kind of social threat: hearing a comment that diminished the value of a personal story or reframed an experience of acceptance or rejection. There is no reason to assume the same result would appear in the same way in every setting, such as family disputes, teamwork, or watching someone face physical danger. Social embarrassment has its own characteristics, and personality traits may relate to it differently than they do to responses to other kinds of distress.
The Aalto University team’s findings, published in Cerebral Cortex, offer a more precise picture than familiar generalizations about narcissism. This was not a direct measure of how kind or cruel people are. It was an observation about how closely activity in social-cognitive networks was synchronized as people watched someone else’s social standing being challenged. That precision may help researchers ask better questions about how people understand one another and what makes understanding easier or harder.
The Bottom Line
In a study of 58 participants—28 with high scores and 30 with low scores on measures of grandiose narcissistic traits—the higher-scoring group showed less similar patterns of activity in the dlPFC and PCC while watching someone receive a remark that threatened their social image. The difference in the anterior insula was not statistically significant. The experiment used interactive video scenes inspired by the idea of protecting one’s social image, and it did not explicitly ask viewers to empathize.
The findings do not mean that everyone with higher scores lacks empathy, and they do not prove that a pattern of brain activity causes relationship problems. Instead, they suggest that people in the higher-scoring group may process social situations less similarly to one another, in regions that help us understand context and other people’s perspectives. The study offers a way to investigate personality and brain responses using scenes closer to real interactions, while keeping conclusions within the limits of what the researchers actually measured.
