Bots Outperform Humans if They Impersonate Us
Last year, Google unveiled Duplex, its artificial-intelligence-powered assistant.
“How can I help you?”
“Hi, I’m calling to book a women’s haircut for a client. Um, I’m looking for something on May 3rd.”
That’s a robot.
“Sure, give me one second.”
“For what time are you looking for around?”
The machine assistant never identified itself as a bot in the demo. And Google got a lot of flak for that. They later clarified that they would only launch the tech with “disclosure built in.”
But therein lies a dilemma, because a new study in the journal Nature Machine Intelligence suggests that a bot is most effective when it hides its machine identity.
但这里存在一个两难的问题，因为发表在《自然机器智能》(Nature Machine Intelligence)杂志上的一项新研究表明，当机器人隐藏自己的机器身份时，效率最高。
“That is, if it is allowed to pose as human.”
Talal Rahwan is a computational social scientist at New York University’s campus in Abu Dhabi. His team recruited nearly 700 online volunteers to play the prisoner’s dilemma—a classic game of negotiation, trust and deception—against either humans or bots. Half the time, the human players were told the truth about who they were matched up against. The other half, they were told they were playing a bot when they were actually playing a human or that they were battling a human when, in fact, it was only a bot.
And the scientists found that bots actually did remarkably well in this game of negotiation—if they impersonated humans.
“When the machine is reported to be human, it outperforms humans themselves. It’s more persuasive; it’s able to induce cooperation and persuade the other opponent to cooperate more than humans themselves.”
But whenever the bots’ true nature was disclosed, their superiority vanished. And Rahwan says that points to a fundamental conundrum. We can now build really efficient bots—that perform tasks even better than we can—but their efficiency may be linked to their ability to hide their identity—which, you know, feels ethically problematic.
“Those very humans who will be deceived by the machine, they are the ones who ultimately have to make that choice. Otherwise it would violate fundamental values of autonomy, respect and dignity for humans.”
It’s not realistic to ask people for consent before every bot-human interaction. That would, of course, reveal the bots’ true identity. So we, as a society, will have to figure out if making our lives a bit easier is worth interacting with bots that pretend to be human.
