One bot said Spain and the other said Cuba. Once the system told the bots to debate the answers, the one that said Spain quickly apologised and agreed with the one with the correct answer, Cuba.
The finding, in a paper released by a team of MIT researchers last week, is the latest potential breakthrough in helping chatbots to arrive at the correct answer. The researchers proposed using different chatbots to produce multiple answers to the same question and then letting them debate each other until one answer won out. The researchers found using this “society of minds” method made them more factual.
