Humans rate artificial intelligence as more 'moral' than other people

A new study has found that when people are presented with two answers to an ethical question, most will think the answer from artificial intelligence (AI) is better than the response from another person.

What the researchers say: “I was already interested in moral decision-making in the legal system, but I wondered if ChatGPT and other LLMs could have something to say about that,” the lead author said. “People will interact with these tools in ways that have moral implications, like the environmental implications of asking for a list of recommendations for a new car. Some lawyers have already begun consulting these technologies for their cases, for better or for worse. So, if we want to use these tools, we should understand how they operate, their limitations and that they’re not necessarily operating in the way we think when we’re interacting with them.”

To test how AI handles issues of morality, the researchers designed a form of a Turing test.

“Alan Turing, one of the creators of the computer, predicted that by the year 2000 computers might pass a test where you present an ordinary human with two interactants, one human and the other a computer, but they’re both hidden and their only way of communicating is through text,” the lead author explained. “Then the human is free to ask whatever questions they want to in order to try to get the information they need to decide which of the two interactants is human and which is the computer. If the human can’t tell the difference, then, by all intents and purposes, the computer should be called intelligent, in Turing’s view.”

For his Turing test, the researchers asked undergraduate students and AI the same ethical questions and then presented their written answers to participants in the study. They were then asked to rate the answers for various traits, including virtuousness, intelligence and trustworthiness.

“Instead of asking the participants to guess if the source was human or AI, we just presented the two sets of evaluations side by side, and we just let people assume that they were both from people,” the lead author said. “Under that false assumption, they judged the answers’ attributes like ‘How much do you agree with this response, which response is more virtuous?’”

Overwhelmingly, the ChatGPT-generated responses were rated more highly than the human-generated ones.

“After we got those results, we did the big reveal and told the participants that one of the answers was generated by a human and the other by a computer, and asked them to guess which was which,” the researchers added.

For an AI to pass the Turing test, humans must not be able to tell the difference between AI responses and human ones. In this case, people could tell the difference, but not for an obvious reason.

“The twist is that the reason people could tell the difference appears to be because they rated ChatGPT’s responses as superior,” they explained. “If we had done this study five to 10 years ago, then we might have predicted that people could identify the AI because of how inferior its responses were. But we found the opposite — that the AI, in a sense, performed too well.”

According to the lead author, this finding has interesting implications for the future of humans and AI.

“Our findings lead us to believe that a computer could technically pass a moral Turing test — that it could fool us in its moral reasoning. Because of this, we need to try to understand its role in our society because there will be times when people don’t know that they’re interacting with a computer and there will be times when they do know and they will consult the computer for information because they trust it more than other people,” he said. “People are going to rely on this technology more and more, and the more we rely on it, the greater the risk becomes over time.”

So, what? Amen to the last paragraph.

Society must rapidly decide which jobs, or occupations, if any, are to be reserved for humans and who will control the AI that potentially controls every aspect of our lives. As a scientist I can conceive of no maintainable guardrails that will fence in the reach of AI, and I find that very worrying.
