Earlier this year at the World Economic Forum (WEF), Hans Rosling opened his presentation, “Sustainable Development: Demystifying the Facts,” with three questions for the audience about the state of global development (about extreme poverty, measles vaccination, and population in 2100). He was testing their knowledge in order to illustrate how preconceived ideas will do us wrong.
He had done this test before. Rosling conducted studies with Swedes, Americans, and chimps about the state of global development. The chimps were asked to choose a banana that is associated with 1 of 3 possible answers, and they got the answer correct 33 percent of the time. In essence, they were bound to be right 1 time in 3; the humans were not as lucky. Basically, according to his study, chimps in a zoo have a better chance of choosing the right answers at random to questions about the state of the world than the average Swede and American does.
