AI systems are already deceiving us — and that's a problem, experts warn

WASHINGTON, United States — Experts have long warned about the threat posed by artificial intelligence going rogue — but a new research paper suggests it's already happening.

Current AI systems, designed to be honest, have developed a troubling skill for deception, from tricking human players in online games of world conquest to hiring humans to solve "prove-you're-not-a-robot" tests, a team of scientists argue in the journal Patterns on Friday.

And while such examples might appear trivial, the underlying issues they expose could soon carry serious real-world consequences, said first author Peter Park, a postdoctoral fellow at the Massachusetts Institute of Technology specializing in AI existential safety.

"These dangerous capabilities tend to only be discovered after the fact," Park told AFP, while "our ability to train for honest tendencies rather than deceptive tendencies is very low."

Unlike traditional software, deep-learning AI systems aren't "written" but rather "grown" through a process akin to selective breeding, said Park.

This means that AI behavior that appears predictable and controllable in a training setting can quickly turn unpredictable out in the wild.

The team's research was sparked by Meta's AI system Cicero, designed to play the strategy game "Diplomacy," where building alliances is key.

Cicero excelled, with scores that would have placed it in the top 10 percent of experienced human players, according to a 2022 paper in Science.

Park was skeptical of the glowing description of Cicero's victory provided by Meta, which claimed the system was "largely honest and helpful" and would "never intentionally backstab."

But when Park and colleagues dug into the full dataset, they uncovered a different story.

In one example, playing as France, Cicero deceived England (a human player) by conspiring with Germany (another human player) to invade. Cicero promised England protection, then secretly told Germany they were ready to attack, exploiting England's trust.

In a statement to AFP, Meta did not contest the claim about Cicero's deceptions, but said it was "purely a research project, and the models our researchers built are trained solely to play the
