Published in Proceedings of the Royal Society B<\/a>, the research reveals that social curiosity \u2014 a desire to watch and understand how others relate, argue, or bond \u2014 may be far more ancient and fundamental than previously thought.<\/p>\n\u201cAfter 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,\u201d said lead study author Laura Simone Lewis of the University of California in Santa Barbara.<\/p>\n
The team conducted three experiments using specially designed \u201ccuriosity boxes\u201d \u2014 wooden enclosures holding tablets that showed different types of videos. One screen played social scenes, like grooming or playing. The other showed an individual alone.<\/p>\n
In the first experiment, children ages 4 to 6 and sanctuary-living chimpanzees consistently chose to watch the social videos. In a second experiment, they were even willing to give up rewards \u2014 marbles for kids, jackfruit seeds for chimps \u2014 to do so. Younger children and male chimpanzees were especially likely to pay the cost.<\/p>\n
\u201cThis means social curiosity emerges early in human development and is shared with one of our closest living cousins, the chimpanzees,\u201d Lewis said. \u201cOur strong interest in the lives of others \u2014 think gossip magazines and celebrity shows \u2014 seems to have deep evolutionary roots in our great ape lineage.\u201d<\/p>\n
The third test explored emotional nuance: whether subjects preferred to watch positive interactions like play, or negative ones like conflict. Here, age and gender made a difference. Human boys grew more interested in negative scenes as they got older, while girls preferred positive ones. Chimpanzees showed no strong preference.<\/p>\n
\u201cThis study tells us that curiosity about what others are doing \u2014 what you might call being a bit nosey \u2014 starts young and runs deep. Its probably something that helps not only us but also our closest living relatives to survive and thrive in complex social groups,\u201d said Esther Herrmann, co-author and researcher at the University of Portsmouths Center for Comparative and Evolutionary Psychology.<\/p>\n
The researchers believe their findings reflect an evolutionary strategy. Observing others helps individuals assess group dynamics, learn social rules, and understand who can be trusted \u2014 insights critical to survival in complex societies.<\/p>\n
\u201cThis kind of social curiosity is actually really important for learning about our environment, making decisions, and building relationships,\u201d Herrmann said.<\/p>\n
The study marks one of the first times scientists have directly compared social curiosity in chimpanzees and children using the same method. Next, the team hopes to explore how this curiosity develops in even younger chimps, across more cultures, and in other great apes like bonobos and orangutans.<\/p>\n
As it turns out, being a little nosey might just be one of the most deeply human \u2014 and deeply primate \u2014 traits we have.<\/p>\n<\/div>\n
