Some researchers in Germany recently decided they might make excellent guinea pigs. They wanted to see if chatbots would respond to certain psychological prompts the way humans do: If they tried to induce the chatbots to feel sad or angry, how would they respond?
To their surprise, they were able to coax them into very specific emotional states like sadness or stress. Once they had induced these states, the chatbot would reflect the emotional bias back to them in simple sentence completion tasks. The scientists published their results in The Lancet.
