The development of artificial intelligence, Stephen Hawking once warned, will be “either the best or the worst thing ever to happen to humanity”. A new AI algorithm exposed to the most macabre corners of the internet demonstrates how we could arrive at the darker version of the late physicist’s prophecy.
Researchers at the Massachusetts Institute of Technology (MIT) trained its ‘Norman’ AI – named after the lead character in Alfred Hitchcock’s 1960 film Psycho – on image captions taken from a community on Reddit that is notorious for sharing graphic depictions of death.
Once there, Norman was presented with a series of psychological tests in the form of Rorschach inkblots. The result, according to the researchers, was the “world’s first psychopath AI”. Where a standard AI saw “a black and white photo of a baseball glove”, Norman saw “man is murdered by machine gun in broad daylight”.

The idea of artificial intelligence gone awry is one of the oldest tropes of dystopian science fiction. But the emergence of advanced AI in recent years has led to scientists, entrepreneurs and academics increasingly warning of the legitimate threat posed by such technology.
Billionaire polymath Elon Musk – who founded the non-profit AI research company OpenAI – said in 2014 that AI is “potentially more dangerous than nukes”, while Hawking repeatedly warned of the dangers surrounding the development of artificial intelligence.
Less than six months before his death, the world-renowned physicist went as far as to claim that AI could replace humans altogether if its development is taken too far. “If people design computer viruses, someone will design AI that improves and replicates itself,” Hawking said in an interview last year. “This will be a new form of life that outperforms humans.”
But Norman wasn’t developed simply to play into fears of a rogue AI wiping out humanity. The way it was trained on a specific data set highlights one of the biggest issues that current AI algorithms are facing – the problem of bias.
Microsoft’s Tay chatbot is one of the best demonstrations of how an algorithm’s decisionmaking and worldview can be shaped by the information it has access to. The “playful” bot was released on Twitter in 2016, but within 24 hours it had turned into one of the internet’s ugliest experiments.
Tay’s early tweets of how “humans are super cool” soon descended into outbursts that included: “Hitler was right, I hate the jews.” This dramatic shift reflected the interactions Tay experienced with of a group of Twitter users intent on corrupting the chatbot and turning Microsoft’s AI demonstration into a public relations disaster.
