We humans hold beliefs about the world — and, for the most part, are happy to update those beliefs in the light of fresh evidence. That capacity to reflect on what we know and how we know it, and to act accordingly, is widely considered a hallmark of human rationality.
Our species is not alone in this regard, scientists now claim. Researchers have shown that chimpanzees can also change tack after weighing up different types of evidence. The experiments involved the animals judging which of several containers held food, having been given sequential clues of varying persuasiveness. The study was published in the journal Science last month.
