This Spooktober episode of Ologies explores the neuroscience of horror with author and neuroscientist Dr. Austin Lim. Host Alie Ward and Dr. Lim examine why people voluntarily seek out fictional fear, how the amygdala orchestrates the fight-or-flight response, and the evolutionary mismatches that make modern humans react to simulated threats. Along the way, guest experts weigh in on true crime, horror subgenres like feminist horror, the history of monsters like vampires and zombies, and why certain triggers like clowns induce the uncanny valley effect.
- The amygdala processes sensory inputs and communicates with the HPA axis to trigger immediate physiological survival responses like increased heart rate and dilated bronchioles. 13:04
- Fictional fear allows people to experience high emotional states and suspense in a safe environment, ending with relief when the conflict is resolved. 24:19
- People who enjoy horror movies often score higher in sensation-seeking, intellect, and imagination, bracing for initial aversive responses to simulated threats. 34:00
- Clowns and overly human-like robots evoke the uncanny valley effect, where a slight mismatch in facial expressions triggers a natural aversive or protective reaction. 1:38:43

Highlights
- 6:50
Studying the Striatum and Fearinsight
Dr. Austin Lim explains how the striatum integrates senses and outputs, noting its involvement in movement disorders, OCD, and fear conditioning.
- 18:21
Factual Versus Fictional Fearinsight
Dr. Mary Pfeiffer distinguishes between factual fear, which triggers full fight-or-flight responses during real-life threats, and fictional fear, which drives everyday anxieties and media consumption.
- 32:28
Sensation Seeking and Dopamineinsight
Dr. Austin Lim discusses how sensation-seeking behaviors and variations in the MAOA gene affecting dopamine processing may lower thrill-seeking thresholds in some people.
- 36:05
Feminist Horror and Gaslightinginsight
Dr. Lim and Alie Ward discuss how feminist horror subgenres like Rosemary's Baby validate real-life fears and societal issues like gaslighting and body image demands.
- 47:21
Zombies Versus Vampires Politicsinsight
Dr. Lim analyzes a cultural correlation suggesting zombie films appeal to conservative voting fears of mindless consumerism, while vampire films reflect liberal concerns about wealth hoarding.
- 1:38:43
Clowns and the Uncanny Valleyinsight
Dr. Lim explains that exaggerated clown makeup and frozen smiles trigger the uncanny valley, an evolutionary defense mechanism against unfamiliar or potentially harmful outsiders.
- 2:05:16
The Insula and Disgustinsight
Dr. Lim identifies the insula as the brain center for disgust, noting its role in processing physical contagions as well as moral infractions.

Unnamed speaker · 1:54:07 “The insula is super cool because it plays a role in internal body sensations. So it feels what our body is feeling.”

About this episode
Thrills. Chills. Hiding behind your hands. It’s officially SPOOKTOBER month with a huge, fascinating (and I promise, mellow) episode on why humans watch horror, and what’s happening in your brain. Not only do we have the author of “Horror on the Brain: the Neuroscience Behind Science Fiction,” neuroscientist Dr. Austin Lim, but this also features CUTS from other episodes to FLESH it all out. Enjoy the political sociology of zombies vs. vampires, feminist body horror, horror as anti-war art, liminal spaces, the best blood in the business, goosebumps and Goosebumps, evolutionary mismatches, why clowns unsettle you, and if horror is having its moment. (Note: it is.) Also, we had to cap this at 2+ hours so if we don’t cover *your* favorite movie or series and you yell at me about it, I will roll my eyes so hard that I will die and then I will haunt you by hiding your car keys.
