We recently reported a study [1] where chimpanzees and bonobos faced decisions between a ‘framed’ option that provided either one or two pieces of fruit, and an alternative option that always provided a constant number of peanuts. We found that apes (especially males) chose the framed option more when it was presented as a gain—apes initially saw one piece of fruit, but sometimes got two after making a choice—than when it was framed as a loss—apes saw two fruits, but sometimes received only one. We argued that the apes showed human-like framing effects, because they judged the fruit option as more desirable when it was presented as a gain than as a loss, despite equivalent payoffs. In a commentary, Kanngiesser & Woike [2] claimed that the apes actually exhibited a pattern opposite of that typically seen in humans...
