Why are humans hooked on horror?

Horror offers opportunities to safely experiment with fear

Researchers at Denmark’s Aarhus University study people attracted to what they call “recreational fear,” which includes any media (like a horror movie) or experience (like a haunted house) that’s intended to give them a scare. They say these people appreciate playing with fears and anxieties safely.

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.

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.

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.

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.

Fear (and stress) can be contagious via pheromones secreted by the body

While seeing someone else in a panicked state may induce a stress response, researchers have found stress can be literally contagious—chemicals contained in sweat and other secretions can trigger stress hormone release in others. Theories suggest this feature is an evolutionary adaptation to protect groups from danger.

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 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.”

Goose bumps are often triggered by emotions

A physiologist and professor of zoology explains that the subconscious release of adrenaline, a stress hormone, causes a contraction of skin muscles. It’s released in several situations, including when humans are cold, afraid, or feel strong emotions. (Some readers may experience a paywall.)

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.

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.

What exactly is dopamine?

Dopamine is a neurotransmitter—a chemical released by neurons that enables neural communication—that makes people want things with an "almost animalistic desire," compelling them to snack or check phone notifications. Often misrepresented as a "pleasure" chemical, dopamine is involved in motivation, learning, attention, habit formation, and more. Trends like dopamine fasting overinflate its role in mental health and often use it as part of "straw man" biohacking claims.

Fear or disgust related to clusters of holes and cracks, called trypophobia, may stem from evolutionary processes to help us avoid pathogens.

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.

Fear or disgust related to clusters of holes and cracks, called trypophobia, may stem from evolutionary processes to help us avoid pathogens

This type of extreme reaction to harmless holes, dots, cracks, and seed collections can be debilitating for those who have it, but it is not an officially recognized disorder in the DSM-5.

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

Some vacationers flock to the sites of tragedies

Auschwitz, Chernobyl, Gettysburg, and more have all become tourist destinations, despite the horrible events that have occurred at the sites. The phenomenon is sometimes called "dark tourism," a trend that seems to be spurred by interest in history, morbid curiosity, and popular culture (like HBO's series "Chernobyl").

Learn about the neuroscience and psychology of why we crave comfort foods

The term was coined in 1966, when psychologist Joyce Brothers suggested humans turn to food associated with the feelings of comfort from their childhoods when experiencing emotional distress. Since then, studies have shown that the familiarity, reliability, and convenience of certain foods from one's upbringing can become tied to feelings of nostalgia.

Humans can track smells on the ground quite well—our ability to crawl is a limiting factor

As part of a scientific bet, neurobiology researchers dragged a chocolate bar across the grass and sought to see if a human could track it—she could. This led to a more in-depth experiment on human olfactory capabilities and behavior when other senses were blocked.

The limbic system drives emotion, memory, and survival instincts in the brain.

This interconnected group of brain structures—including the amygdala, hippocampus, thalamus, and hypothalamus—processes emotional responses, regulates bodily functions, and plays a key role in memory and learning.

The history of torturing robots

When machines fail, its easy to get mad and even give them a good kick. But as humanoid robots become more sophisticated, the degree to which people abuse them has shifted, depending on how much emotion the robot expresses. Studies revealed when robots were programmed to cry during distress, participants felt empathy. Learn more about the history of human abuse of robots here.

There are 5 key reasons why people carry out hoaxes

While it's hard to pinpoint just one motive for trickery, many cases indicate that hoaxers are seeking attention. Other reasons include making a profit, or simply that fooling others is fun.

Why dystopian literature remains popular

Yale English professor Joe Cleary argues that dystopian literature’s continued relevance is due to a torrent of additional societal anxieties and that the streaming adaptations of dystopian classics "The Handmaid’s Tale" and "The Man in the High Castle" have expanded the genre’s popularity, introducing new audiences to its tropes.

Why don't humans hibernate?

This essay in Aeon explains this helpful natural process and why humanity's technological advancements may have hindered our ability to participate in the practice. Learn about the rising interest in human hibernation as a result of modern adversity, and if it could potentially become a reality.

At its root, cringe comedy is about empathy

Cringe comedy has never been more popular, even if it's too uncomfortable for some people to bear. Sören Krach, a professor of psychiatry at Germany’s Lübeck University who coauthored a paper on cringe comedy, notes that, although it may seem cruel, at the core of watching cringe comedy is empathy.

A researcher thinks she knows why people keep touching museum exhibits

A museologist who studied unauthorized touch at the British Museum concluded that people may feel it's difficult to learn about things "unless you handle them" and that people are trying to connect with the past, viscerally. Her work has included interviewing British Museum visitors who committed unauthorized touches and spending extensive periods observing people touching prohibited items across 2004 and 2005.

Cordyceps: the fungi that turn ants into zombies

The hit show (and video game) "Last of Us" was inspired partly by real-life species of fungi that have been known to turn ants into zombies. Spores of the Cordyceps fungi are capable of penetrating the exoskeletons of arthropods, after which they break into enzymes and proliferate within the body. The fungal cells then hack the ant's nervous system and trigger compulsive climbing.
