A scientific report published in the journal Science indicates that the ability to imagine is not a purely human characteristic. During a recent study, researchers from Johns Hopkins University and the University of St. Andrews observed a captive bonobo named Kanzi to see if apes could understand make-believe scenarios. This mental skill, which serves as the bedrock of human invention, involves pretending that a situation is real despite knowing it is false. While some wild chimpanzees have displayed similar behaviors with sticks, this experiment provides the first formal data regarding such mental processes in primates. The findings suggest that the capacity for creative thought might be innate to several species within the great ape family.

The investigation involved a series of social tests where scientists poured invisible liquid into containers. Kanzi successfully identified the cup that was supposed to hold the liquid in 68% of the attempts, showing an understanding of abstract concepts. To verify that the animal was not simply confused, the team offered a choice between actual juice and the fake version. The bonobo selected the real option in 80% of the cases, which proves a clear distinction between reality and pretense. However, critics like Michael Tomasello argue that more evidence is needed to confirm a comprehensive understanding of imagination. These experts believe the unique environment of a laboratory might influence such results. Regardless of these debates, the study remains a pivotal development in the field of animal psychology.
