“‘Historically, these systems have not been good at saying, ‘I just don’t know the answer,’ and when they don’t know the answer, they just make stuff up,’ Conitzer said. ‘Kind of like a student on an exam that says, well, if I say I don’t know the answer, I’m certainly not getting any points for this question, so I might as well try something. The way these systems are rewarded or trained is somewhat similar.’”
