After Watching a TV Drama, the Brain Tracked Rivalries More Clearly Than Friendships

In A Nutshell

  • A brain imaging study found that after college students watched episodes of Suits, certain brain regions showed activity patterns tied specifically to on-screen rivalries.
  • Comparable patterns for friendships didn’t clear the study’s statistical bar.
  • The research involved 21 students watching a fictional legal drama, not real-world relationships.
  • Researchers say hostile ties may act as anchors when the brain builds a mental map of a social world learned through narrative.

Watching a TV show may largely feel like mental relaxation, but beneath the surface our minds are still at work. A brain imaging study suggests that when people learn who’s feuding with whom on screen, certain brain regions take special notice. Researchers compared how the brain responded to the faces of eight characters from the legal drama Suits before and after volunteers watched six episodes, and found that neural activity linked to hostile relationships showed up more clearly than activity linked to friendly ones.

Published in Communications Psychology, the study adds a wrinkle to research on how the brain builds a “social map,” an internal picture of how people in a group relate to each other. Much of that research has focused on the warmer side of social life: friendship, cooperation, trust. This study points to something else.

Researchers frame the idea with a line from a politician character played by Al Pacino in the 1996 film City Hall: “A man’s stature is determined by his enemies, not his friends.” It’s a dramatic way of putting it, and the study itself is narrower than that quote implies: 21 college students watched a fictional drama in a lab setting. Whether the same pattern applies to real coworkers, friends, or family members remains an open question.

College Students Watched Six Episodes of ‘Suits’ for Science

Researchers recruited 21 college students, 12 men and 9 women between 19 and 23, none of whom had seen Suits before. Each had their brain scanned by MRI while looking at photos of the show’s eight main characters, before watching a single episode. Then they went home and watched the first six episodes, about five hours of television spread across several days, and returned roughly two weeks later for a second brain scan while looking at the same faces.

To confirm people had actually paid attention, researchers asked comprehension questions after each episode; participants averaged 90 percent accuracy. After the second scan, participants rated all 28 possible pairings of the eight characters on two scales: how strong the relationship seemed, and whether it felt friendly or hostile. The strongest bonds tended to sit at the extremes, either clearly friendly or clearly hostile, while weaker connections between characters who barely interacted clustered closer to neutral.

Three Brain Regions Lit Up for On-Screen Rivalries

Researchers then compared how similar or different the brain’s response was to each pair of characters, and tested whether those differences lined up with how participants rated the pairs as hostile or friendly, while accounting for how similar the characters’ faces looked to each other.

Three brain regions showed activity patterns tied specifically to antagonistic relationships: the left anterior supramarginal gyrus, an area linked to reading other people’s intentions; the left superior parietal gyrus; and the right medial prefrontal cortex, a region tied to thinking about other people and making social judgments. Researchers found clear neural patterns associated with antagonistic relationships, while comparable effects for friendly relationships weren’t strong enough to count as real findings by the study’s own standards. That gap doesn’t prove friendships go unrepresented in the brain; it may simply reflect the limits of a small study’s statistical power.

Scans also picked up something in the precuneus, a region tied to autobiographical memory. Overall activity there increased after the drama, though it didn’t track the specific web of relationships the way the other two regions did. Researchers see this as a possible division of labor: one set of regions may store memories about individual people, while regions toward the front and sides handle a more abstract map of who opposes whom. Watching the drama also made the brain’s responses to different characters grow more distinct from each other overall, a broader sign that the show sharpened how individually the brain represented each character.

Conflict May Anchor the Brain’s Social Map, Researchers Say

One possible explanation comes from earlier psychological research showing that negative social information can carry outsized weight in personal memory, workplace dynamics, and international politics. The new study didn’t directly test whether conflict was more memorable or emotionally powerful; it measured brain activity patterns, not memory or emotion.

This study’s sample was small and entirely college-aged, and it didn’t ask participants to actively judge relationships while being scanned; the social structure was picked up as a byproduct of simply viewing faces. The researchers note that future work should test whether the pattern holds with larger, more varied groups, and what happens when people are asked to reason directly about who’s on whose side.

At least when people learn a social world through a television drama, hostility and rivalry appeared to leave a clearer neural signature than warmth and alliance. That’s a narrower claim than “the brain prioritizes enemies,” but a genuinely interesting one. It suggests conflict may serve as a particularly useful anchor point when people are piecing together a map of who stands where, at least in the fictional worlds many spend hours absorbing.


Paper Notes

Limitations

Study authors note that participants were not asked to actively evaluate or reason about character relationships during the brain scans; the social structure was captured implicitly. Future studies that directly prompt participants to make relational judgments, such as by presenting character pairs, could shed more light on how the brain processes explicit social reasoning. The researchers also note that significant effects tied to relationship structure were not observed in the hippocampus, despite previous studies pointing to that region as central to social mapping; they suggest this may reflect differences in task demands, since prior studies required active social navigation while this one did not. The study was not preregistered. The participant pool consisted entirely of college-aged individuals, and information on gender identity, race, ethnicity, and socioeconomic status was not collected, which limits how broadly these findings can be generalized.
