Chimpanzees share a remarkable 99% of their DNA with humans. Despite this striking genetic similarity, many assume human cognitive abilities far surpass those of our primate cousins. However, recent research suggests this assumption may be premature. While humans have achieved remarkable feats like flight and disease cures, chimps excel in several fundamental cognitive tasks. This article explores the surprising intelligence of chimpanzees and challenges the notion of absolute human superiority.
Chimpanzee Cognitive Prowess: Surprising Wins for Apes
Several studies reveal intriguing instances where chimpanzees outperform humans in specific cognitive domains. These findings challenge the traditional view of human intellectual dominance.
Strategic Thinking: Mastering the Game
A 2014 Kyoto University study pitted pairs of humans and chimpanzees against each other in a strategic game resembling “Rock, Paper, Scissors.” Researchers observed that chimps consistently reached the optimal game strategy, predicted by game theory, faster than their human counterparts. This suggests that the competitive nature of chimpanzee societies may have honed their strategic thinking skills.

Problem-Solving: The Inaccessible Peanut Task
The “inaccessible peanut task” presents another intriguing example of chimpanzee ingenuity. In this experiment, a peanut is placed at the bottom of a transparent tube, out of reach. While young children struggled to retrieve the treat, chimpanzees quickly devised a solution: filling their mouths with water and spitting it into the tube to raise the peanut. This resourceful approach highlights chimps’ superior problem-solving abilities in this specific context.
Working Memory: A Speed Advantage
A 2007 study further demonstrated chimpanzees’ exceptional working memory – the ability to retain and apply information rapidly. Both chimpanzees and humans participated in a number-ordering game. While accuracy rates were similar, chimps significantly outpaced humans in speed, showcasing their remarkable ability to process and utilize information quickly. Even with extensive training, human participants couldn’t match the chimps’ speed.
Rethinking the Bias: Are We Underestimating Chimpanzee Intelligence?
Primatologist Frans de Waal criticizes the prevalent “Neo-Creationism” bias, which assumes human minds are uniquely evolved and incomparable to other species. This bias may have skewed research methodologies, potentially underestimating chimpanzee cognitive abilities. For instance, historical testing conditions often disadvantaged apes, with factors like testing through bars and limited social interaction potentially hindering their performance.
A 2017 study highlighted methodological flaws in previous research, arguing that testing environments, preparation, and procedures often favored humans. This suggests that the scientific community may be significantly underestimating the true cognitive potential of chimpanzees.
Conclusion: A More Nuanced View of Intelligence
The evidence suggests that chimpanzee intelligence is more complex and nuanced than previously assumed. While humans undoubtedly possess unique cognitive strengths, chimpanzees excel in specific domains like strategic thinking, problem-solving, and working memory. Future research with more equitable methodologies may reveal further surprises about the cognitive landscape of our closest living relatives. A clearer understanding of chimpanzee intelligence not only sheds light on their remarkable abilities but also challenges anthropocentric views of intelligence and encourages a deeper appreciation for the cognitive diversity within the animal kingdom.
