Description:
Social media is full of AI-generated images and videos that may look flawless but feel off. Experts say the uncanny valley might explain our uneasy reactions to them.

FULL STORY ======================================================================

Scroll through social media, and its almost impossible to avoid AI-generated images and videos. At first glance, they can look realistic. But stare a little longer and they often start to feel a little off.

Maybe its the lighting that doesnt quite make sense, the skin thats too smooth, or the infamous extra fingers. Theyre not always obvious fakes, and
as the tech improves, its harder to tell for sure - take a look at Sora 2 . But its hard to shake the feeling that something often isnt right.

That uneasy feeling got me thinking. Is this just another version of the uncanny valley? A concept thats been around for decades to explain why humanoid robots can creep us out. Could it also apply to the flood of AI images and videos filling our feeds?

Ive written before about the rise of AI slop and the strange ways we react to machine-made content. This time, I asked researchers who study the uncanny valley whether its principles could also apply to the digital realm. Welcome to the uncanny valley

The uncanny valley effect describes how we react emotionally when things
start to seem increasingly human, says Dr Steph Lay , a horror writer, psychologist, and expert on the uncanny.

At first, we respond positively, but that only holds up to a point. If something gets too close to human but still isnt perfect, we start to react with disquiet or unease, even disgust. Think of dolls, clowns, or statues. Theres something creepy about how theyre nearly human but not quite right,
Lay says.

Researchers think this sensitivity has evolutionary roots. Spotting small irregularities in faces and bodies may once have helped us avoid danger, detect illness or decide who to trust. Blame the robots

The concept of the uncanny valley is most often applied to humanoid robots. Especially the kind youve probably seen unveiled at tech conferences. But not all robots are unsettling; our expectations play a big role.

I did some research into how people would feel about having a robot living as a companion in their homes, and most people baulked at the idea of sharing their home with a near-human helper, Lay tells me. They would feel much more comfortable with something that looked definitely artificial.

Dr. Christoph Bartneck , a professor of human-robot interaction in the department of Computer Science and Software Engineering at the University of Canterbury, says it comes down to how closely we scrutinise human likeness. The more human-like a robot or AI-generated character becomes, the higher our expectations. We dont expect a floor cleaning robot to exhibit biological movement. It is okay if it moves like a machine.

"But once the robot becomes human-like, we apply human standards," Bartneck explains. "Were sensitive to small changes in facial expressions, gestures, and posture. Even the slightest irregularity in someones gait can throw us off.

Its these small changes, the barely-there glitches in a movement or smile or walk, that tip us into the uncanny valley. When the uncanny hits your feed

So what happens when the almost-human figure in front of us isnt a robot on a stage but an image or a video online?

With AI-generated content, theres often something that the algorithm gets wrong, Lay says. Even when the overall image looks polished and perfect, that flaw tips us into that disquieting valley. We might not be able to explain
why straight away, but something definitely feels off.

Interestingly, Lay doesnt think our instinct to spot those flaws will fade, even as AI improves. I think this sensitivity will always be there. Were very closely attuned to whats real and whats not, particularly when it comes to faces.

We may adapt, but not in the way AI companies might hope. With the current advances in image and video generation technology, were in an unprecedented period for exposure to things that arent real. Our perceptual systems are primed to learn and adapt, so I think well just get more discerning over
time. The real stakes of fake faces

The uncanny valley feeling can also shape how we respond to the content
around us.

I was interested to know whether people care if the things they see are real or not. In my experience, people absolutely care, Lay says. It all comes down to the reason the image was generated. She points to her own work on Into The Fog, a YouTube channel telling paranormal stories. Because the creators are transparent about which images and videos are AI-made and which are archival, audiences accept them as part of the storytelling and atmosphere-building.

The problem is when that same content shows up in our feeds with no label or context. If were talking about AI content we encounter on social media, that doesnt come to us in a neutral way, its pushed by an algorithm that has been meticulously tuned to show us things that well react to, Lay says.

And once it lands, the effect compounds. The echo chamber effect is real, but its subtle and complex. Very few people deliberately seek out AI content. It comes as a push into our worlds, in spaces we think of as social, so theres already an expectation well engage with it. Spotting the unreal in real time

There may be no way out of the uncanny valley. Our brains are simply too finely-tuned to irregularities. So well probably always feel a bit off about the almost-real AI images and videos filling our feeds.

Thats not a bad thing. It might keep us sharper about whats real and whats not. And if you do struggle to tell, Lay says the old advice still holds. If something looks too perfect, it probably isnt real.

She also suggests stepping away for some perspective if you notice that uncanny, unsettled feeling setting on. If something you see disturbs you,
then get away from the screen for a while, Lay recommends. After all, the
more time you spend staring at the almost-real, the harder it gets to see the truth.
