In a test based on playing an online game, study participants disagreed with 66% of the advice offered by an artificial intelligence. U.S. Army researchers and colleagues at the University of California, Santa Barbara have found a persistent gap in basic knowledge about the use of artificial intelligence (AI), and it is unknown which AI aspects will or will not help military decision-making. The researchers developed an online game in which players obtained points by making good decisions in each round; an AI was used to generate advice in each round, which was shown alongside the game interface. The AI also made suggestions about which decisions players should make, which they were free to accept or ignore. About 66% of human decisions disagreed with the AI, regardless of the number of errors in the suggestions.
