"Chimpanzees Display Surprising Rational Thinking, Study Reveals"

A study from the University of California, Berkeley reveals that chimpanzees exhibit surprising rationality by revising their beliefs based on new information, challenging previous assumptions about animal cognition.

• The research, conducted by psychologists from the University of California, Berkeley and Utrecht University, demonstrates that chimpanzees can rationally update their beliefs, similar to human reasoning.
• Led by UC Berkeley Psychology Postdoctoral Researcher Emily Sanford and Professor Jan Engelmann, the study involved chimpanzees at the Ngamba Island Chimpanzee Sanctuary in Uganda.
• Findings published in Science indicate that chimpanzees possess a level of rationality previously thought to be unique to humans, reshaping our understanding of animal psychology.
