Ever find yourself people-watching in a cafe, or tuning into reality TV just to see who's arguing with who? You're not alone鈥攁nd it turns out, you might have more in common with chimpanzees than you think.

In a new study comparing social curiosity in chimpanzees and children, a team of international researchers have found that both are deeply interested in the interactions of others, even when it comes at a cost.

The research, in Proceedings of the Royal Society B: Biological Sciences, suggests that being curious about social behavior isn't just a human quirk鈥攊t's shared with one of our closest primate relatives.

Lead author, Dr. Laura Simone Lewis at the University of California in Santa Barbara, said, "After years of observing both children and chimpanzees sometimes jumping up in the middle of research games to observe their peers, the research team was inspired to pursue a new social avenue in the blossoming field of curiosity research."

Previously, little was known about the developmental and evolutionary roots of social curiosity, defined as the motivation to gain information about the actions, relationships, and psychology of others.

Now, the research team has found that chimpanzees and young children prefer to watch videos of social interactions compared to videos of a single individual, and young children and male chimpanzees even pay a material cost to gain social information.

"This means social curiosity emerges early in human development and is shared with one of our closest living cousins, the chimpanzees," added Dr. Lewis. "Our strong interest in the lives of others鈥攖hink gossip magazines and celebrity shows鈥攕eems to have deep evolutionary roots in our great ape lineage."

The study involved three experiments and was carried out at the Ngamba Island Chimpanzee Sanctuary in Uganda and at sites in California, including the Oakland Zoo and the Lawrence Hall of Science.

Dr. Esther Herrmann from the University of Portsmouth's Center for Comparative and Evolutionary Psychology co-authored the research. She said, "This study tells us that curiosity about what others are doing鈥攚hat you might call being a bit nosey鈥攕tarts young and runs deep. It's probably something that helps not only us but also our closest living relatives to survive and thrive in complex social groups."

What they did

To measure social curiosity, researchers built two special "curiosity boxes"鈥攚ooden structures that held tablets playing different videos. In each experiment, chimpanzees and 4- to 6-year-old children could choose between opening one box to watch a social interaction (like grooming, playing or arguing) or opening the other box to watch a video of just one individual acting alone.

In the first experiment, both species consistently spent more time watching the social scenes. In the second, participants had to choose between a reward (jackfruit seeds for chimps, marbles for kids) and the chance to watch a social video. Some鈥攅specially younger children and male chimpanzees鈥攃hose the video over the treat.

The final experiment tested whether individuals preferred watching positive interactions (like grooming or play) or negative ones (like conflicts). While chimpanzees didn't seem to show a strong preference either way, human children did: as they got older, boys were more interested in the negative interactions, while girls leaned towards the positive ones.

The study is one of the first to test social curiosity directly in both humans and chimpanzees using the same setup. It suggests our interest in what others are doing鈥攚ho's cooperating, who's falling out, who's worth keeping an eye on鈥攎ay be something we inherited from a common ancestor millions of years ago.

And that curiosity might be more than just entertainment. Watching how others interact helps us understand relationships, avoid trouble, and figure out who we can trust.

Dr. Herrmann added, "This kind of social curiosity is actually really important for learning about our environment, making decisions, and building relationships."

The researchers suggest future studies could explore how social curiosity develops in younger chimpanzees and across different human cultures, as well as compare adults from both species. They also recommend testing other great apes like bonobos and orangutans, and examining how factors like familiarity or relationship type (friends vs. strangers) affect curiosity. These insights could help uncover how social curiosity evolved and why it varies across age, gender, and species.
