The science behind why we're creeped out by 'uncanny valley'

In 1970, Japanese robotics professor Masahiro Mori proposed the "uncanny valley" hypothesis, which suggests that we're most comfortable with objects and beings that are almost but not entirely human. The theory was based on the observation that people tend to feel uneasy around dolls or robots that look too human, because they're not quite right. Recent research has shown that the uncanny valley effect is real and may have to do with our brain's attempts to make sense of ambiguous stimuli.


The uncanny valley is a theory that suggests that when something looks and behaves almost like a human, but isn't quite right, it causes an eerie feeling in people. This phenomenon was first observed by Japanese roboticist. Masahiro Mori noticed that people were more likely to be creeped out by robots that looked and acted almost like humans, but weren't perfect. This "valley" of unease occurs because the brain tries to reconcile the robot's human-like appearance with its non-human behaviour. When the two don't match up, it creates an unsettling feeling in people.



The science behind the uncanny valley


If you've ever seen the movie "The Stepford Wives," you know what the uncanny valley is. It's that feeling you get when something is just a little too human, but not quite right. Scientists have been trying to figure out why we find things that are just shy of being human so creepy for years, and they think they may have finally found an answer.


It all comes down to evolution. Our brains are wired to recognise faces and other human features, because it's important for us to be able to identify people in order to survive. When we see something that looks almost human, but not quite, our brains start to freak out a little bit. We don't know what it is, so we assume it's dangerous.


Theories about the uncanny valley


One theory is that the valley is caused by a mismatch between the character's appearance and the expectations that we have for that appearance. For example, when we see an animated character that looks realistic but moves in a jerky way, it can cause an unsettling feeling because it doesn't match our expectations.


Another theory is that the uncanny valley arises from a fear of death or decay. This could explain why zombies are so popular in horror movies – they combine the aspects of death and decay with something that is still alive, which creates an unsettling feeling.


A third theory is that the uncanny valley occurs because we are trying to identify with the character. When a character looks and behaves realistically but isn't quite right, it can create feelings of confusion and Uncertainty.



Applications of the uncanny valley


The uncanny valley has been used in a number of different contexts, from movies to video games to advertising. In particular, the uncanny valley has been found to be useful in predicting people's reactions to certain kinds of stimuli. For example, one study found that people were more likely to be disturbed by a character that was close to human but not quite human than they were by a character that was completely inhuman. This suggests that the uncanny valley can be used to create characters that are realistic but still disturbing. Additionally, the uncanny valley has been used in advertising to create an unsettling feeling in consumers. This feeling can then be used to promote products or ideas.


The future of the uncanny valley


The future of the uncanny valley is unclear. Scientists are continuing to study the phenomenon, but they have yet to identify a clear cause. Some researchers believe that the uncanny valley is simply a result of humans' natural aversion to anything that looks or behaves too much like them. Others believe that it may be due to an inability to properly interpret certain facial expressions or body movements. Still others think that it may be caused by a fear of death or robots becoming too human-like. No one knows for sure, and more research is needed in order to determine the root cause. However, scientists remain hopeful that they will one day be able to overcome the uncanny valley and create robots that are both realistic and appealing to humans.
