Experiments reveal that new evidence alters chimpanzee choice behaviors, suggesting a complex relationship with beliefs.
Schleihauf et al. (2025) provided a compelling set of experiments that demonstrate that chimpanzees will change their choices when given new evidence about one or more of those choice options.
