This is the scientific reason why we find horror films scary

With All Hallows’ Eve rapidly approaching, you can thank something called the amygdala within the brain for the reason you so often leap out of your seat while watching horror films 

If you look at the highest-grossing films of recent years, you’ll find lots of predictable, Marvel-y type fare – but you’ll also see a strong showing of blockbuster horror films. Get Out, A Quiet Place and It rank as some of the most successful movies of 2017 and 2018.

And as we approach the spooky pumpkin season, here’s the scientific reason why we find horror films so bone-chillingly scary – and why we just can’t get enough of ‘em.

Fundamentally, it boils down to a process within the brain and, more specifically, the amygdala – a small almond-shaped set of neurons located deep in the brain’s temporal lobe that plays an important role in processing emotions like fear.

As Inverse points out, scary films bypass the conscious parts of the brain and directly play on our fight or flight response.

The amygdala is triggered by anything that looks like a threat, sending an alarm racing through your body and causing your adrenal glands to pump you with a boost of adrenaline, which in turns sets your heart racing.

Psycho director Alfred Hitchcock was so aware of the body’s primal response to horror movies the he told scriptwriter Ernest Lehman: “The audience is like a giant organ that you and I are playing.

“At one moment we play this note, and get this reaction, and then we play that chord and they react. And someday we won’t even have to make a movie — there’ll be electrodes implanted in their brains, as we’ll just press different buttons and they’ll go ‘oooh’ and ‘aaah’ and we’ll frighten them, and make them laugh. Won’t that be wonderful?”

Hitchcock knew exactly how to make us all so terrified     

So if we’re being triggered on such a deeply biological level, why do we keep coming back to horror films and why are they so popular?

This can probably be traced to addiction pathways within the body – i.e. we enjoy the rush of adrenaline and want to feel that high again.

There’s also something called the Excitation-Transfer Theory, which suggests that the stimulation we experience via fear can intensify other positive feelings, like when the characters make it out alive.

Now you’re totally clued up on the science behind what makes stuff scary, dive into our list of the best horror films of 2018 so far and the 25 scariest movies on Netflix right now.
