Researchers say that the horror genre offers opportunities to safely experiment with fear.

Why are humans hooked on horror?

A haunted horror attraction in Denmark is regularly stalked by researchers of the world's only laboratory dedicated to understanding fear's good side. Fear is one of many human emotions that correspond to a physiological response. As fear rises, so do adrenaline, cortisol, and heart and breath rates. As it ebbs, the body is flooded with dopamine, a hormone and neurotransmitter associated with desire, learning, and motivation.

Some theorize that horror's artifice turns fear into enjoyment

The “excitation transfer theory” suggests that the unpleasant feelings a jump scare might elicit (like shortness of breath) are quickly relieved when the audience member remembers what they’re witnessing is fake.

Horror is an artistic genre aimed at scaring its audiences

Whether it's a movie, novel, comic book or any of the genre's other terrifying incarnations, horror's primary purpose is to scare its audiences. Throughout its history, the style has evolved and splintered, and now includes many subgenres, like the slasher flick, the found footage film, and even the horror comedy.

The science of fear

The Hidden Brain podcast team explores the science of fear by traveling to a haunted house curated by a scientist to investigate what scares us, and why some people enjoy this sensation more than others.

Researchers are studying roller coasters to improve mental health treatments

Scary rides stimulate our fight-or-flight response while simultaneously releasing feel-good endorphins like dopamine, serotonin, and oxytocin. Once we realize we're in a safe space, we can enjoy the ride and even feel confident and relieved by the accomplishment of overcoming a fearful feat.

Fearology, or the study of fear, explores the difference between stress and fear

Our brains involuntarily respond to our environment and signal alarm when that isn't always needed, triggering responses that include goose bumps. But understanding fear and how to talk our brains into calming down can improve daily life.

Horror video games rely on terrifying sound design

Horror has become a popular gaming genre, which designers say is due, in large part, to the games' soundtracks. Don Veca, the audio director for the game Dead Space, said, “Sound and music prepare the player to be scared – it’s all about the buildup, the tension, and then the release when something jumps out at you.”

Why so many people love roller coasters even though they’re scary

When a threat arises, it triggers our bodies to go into fight-or-flight mode and prepare for danger. However, when no obvious threat to our safety is present, this natural high can become enjoyable. Some people are more likely to enjoy these thrills based on factors like individual brain chemistry or physical health.

Why we pay to be scared

Why do we love roller coasters? It’s not just the speed or height, it’s controlled fear. Your brain thinks you’re in danger, then rewards you with dopamine.

Fear has a specific 'smell'—at least to machines

This excerpt from a Mythbusters episode takes on the smell-of-fear question, comparing the sweat composition of individuals exposed to snakes, rats, and scorpions with that of people exercising. Molecularly, the sweats are different to a gas chromatography machine, but to most noses would be indistinguishable.

‘Horror hosts’ helped build the genre’s cult following

Horror is now considered high art, but much of its cult popularity is due to the B-movies that defined the genre. Starting in the 1950s, many of these low-grade films were licensed on the cheap by television networks to fill airtime, introduced by “horror hosts”—MCs with campy, over-the-top personas.

The jump scare, a horror genre trope, was invented to keep costs low

RKO Pictures hired Val Lewton to produce horror films in the Universal model: small budgets, big spectacles. His first movie was 1942's "Cat People" and he used tension and offscreen terror to save money. A perfect example is the movie's jump scare, a misdirection technique that catches viewers off guard.

Body horror is a subgenre that uses anxieties about appearance

Made popular in the 1980s through films like “The Fly,” the body horror subgenre focuses on physical transformation and violence. It gained significant attention in 2024, thanks to the critical attention “The Substance” received, including an Academy Award nomination for best picture.

Literary theorists distinguish between ‘terror’ and ‘horror’

In her essay “On the Supernatural in Poetry,” gothic novelist Ann Radcliffe defined “terror” as the lurking, unseen specter in a story—something that defined gothic literature. “Horror,” on the other hand, was the explicit portrayal of it. For her, the former was artistic, while the latter was cheap.

Horror evolved from Gothic literature

Although creepy tales can be found in nearly every folk tradition, the roots of modern horror can be traced back to Gothic literature, which focused on the battle between humans and unnatural, evil forces.

A comparative analysis of the romance and horror genres' overlap

Both genres aim to make their readers' hearts pound, albeit in different ways. Romance novelist Trilina Pucci argues that the gap between the two aims is much slimmer than it may seem, with some horror tropes (like a man enraged by the abuse of his wife) and romance tropes (like the subgenre of dark romance) blurring the line.

The best horror movies of all time

The genre has been scaring audiences for over a century, in many different forms and through many other methods. While any list is subjective, this Rotten Tomatoes list is based on the films' aggregate critical scores. We're sure it'll inspire some additions to your watch list—along with some spirited conversations.

Horror stories often rely on tropes

All literary genres use tropes, a word used to describe established plot devices, character types, and themes. Horror has many of them, like the "Creepy Child" and the "Evil Mask." Some are based on folklore, like the "Deal with the Devil."

Folk horror involves remote settings and ancient traditions

Folk horror often features outsiders venturing to isolated areas and finding the locals engaged in disturbing (often occult) traditions. Rather than using supernatural elements, the horror often comes from the locals themselves. Examples include the 1973 film “The Wicker Man” and Shirley Jackson’s 1948 short story “The Lottery”.

Animal phobias are likely the most common type of phobias, followed by an extreme fear of heights.

Contemporary horror novelists on their favorite scary stories

Ten of horror's best writers name the books that still give them nightmares. From established classics, like Stephen King's "IT" and Shirley Jackson's "The Haunting of Hill House," to unexpected picks like Katherine Dunn's "Geek Love," this collection of scary stories is a perfect reading list for Halloween.

Stephen King is drawn to horror's childish power

This 1986 appearance promoting King's directorial debut finds him reflecting on what makes horror, which he says is its ability to strip away pretense, reducing supposedly sophisticated people to terrified children. He also seems to have already soured on the movie business, calling filmmaking "a primitive way to create," a not-so-subtle dig at Stanley Kubrick's adaptation of "The Shining," which notoriously disappointed King.

Ten of the most horrifying moments in film

Many films in the genre lean into gratuitous horror, putting off the average viewer. This list of ten moments highlights particularly terrifying scenes from films that otherwise met with mainstream acclaim, from "Mulholland Drive" to "The Lord of the Rings."

Researchers have investigated the benefits of extreme pain rituals, exploring how and why we engage in these events when humans generally naturally avoid pain and perceive it as a negative experience.

The Hays Code limited the ways horror films could scare audiences

Beginning in 1930, the Hays Code laid out a strict set of guidelines for Hollywood filmmakers to prevent films that might corrupt those with a “susceptible mind.” That meant no graphic violence, no sexual relations outside of marriage (or of a homosexual nature), and no interracial relationships, among other dictums.

The perception of haunted places is influenced by psychology, setting and suggestion

Gothic architecture and tragic histories contribute to the perception of hauntings. Infrasound and black mold can cause experiences reminiscent of paranormal phenomena. Although paranormal investigators use technology to seek natural explanations, many paranormal experiences remain non-falsifiable.

Unlike milder fears, phobias may get in the way of proceeding with your life.

Horror grossed more than $1B at the box office for the first time in 2017

It was the first time the genre broke the barrier for domestic box offices, powered by hits like "Get Out," "IT" and "Split." Since then, horror movies have remained commercial juggernauts: In 2025, the genre surpassed the $1B mark by September.

Ghost stories can help us process death

Scholar Coya Paz’s research into ghost stories indicated that people often use them to grieve and remember tragic histories. Paz notes that specters in stories almost always demand to be acknowledged. She also shares the three most common types of ghosts we hear about are either vengeful, unwelcoming, or comforting.

Horror exploded as a commercial literary genre in the late 1960s

Ira Levin’s 1967 novel “Rosemary’s Baby” showed publishers horror was a viable commercial genre. That was proven again in 1971, with William Peter Blatty’s “The Exorcist” and again in 1974 with Stephen King’s “Carrie.” The books dealt with societal fears (the occult, drugs, sex) during a time of political upheaval.

The science behind ghosts, explored

Every culture has them—restless spirits, haunted houses, things that go bump in the night. But why do we believe in ghosts? Psychologist and skeptic Dr. Chris French joins host Sony Kassam to explore the science behind the supernatural, from sleep paralysis and hallucinations to the brain’s pattern-making instincts.

The best Valentine's Day-themed horror movies

It may seem like an odd combination—a holiday centered on love and a film genre dedicated to fright—but the hyperspecific subgenre thrives on the apparent juxtaposition, along with some campy send-ups of an overly commercialized holiday.

Consuming true crime media can increase stress and anxiety

Consuming true crime media can activate one's sympathetic nervous system, which controls the fight-or-flight response. Staying in this heightened state of vigilance can lead to stress-related illnesses, including hypertension, and mental conditions, including depression and anxiety. Additionally, people who actively consume crime news, whether they consider it to be entertainment or educational in nature, report being more fearful of crime, regardless of actual crime rates.

There are psychological benefits to believing in spirits

A number of psychologists believe religion helps subdue our fears of death by giving us a sense of what’s to come and, therefore, a sense of control over how to ensure the best possible outcome.

How to build curiosity

Change and uncertainty induce stress, but reframing the unknown into an opportunity for discovery has tangible benefits. Approaching change with curiosity enhances activity in the hippocampus and promotes neuroplasticity, promoting learning and serving as a barrier against anxiety. A neuroscientist explains how embracing the unknown, trying small experiments, and other techniques build curiosity.

The ‘Universal Monsters’ series solidified horror as a film genre

Before 1931, most scary movies were billed as “mystery” or “suspense” with grounded explanations for anything "supernatural." That changed with “Dracula,” which presented the character as a real vampire who drank victims' blood. Universal continued adapting similar titles, including HG Wells’ “The Invisible Man” and Edgar Allan Poe’s short stories.
