Everyone loves horror when Halloween is near, and during the month of October we’re regularly being emailed various studies and infographics from unlikely sources. Such is the case with Broadband Choices’s “The Science of Scare,” an infographic put together based on a scientific study that set out to determine the scariest movies ever made.

The outlet explains, “Is there anything better than a night in with the lights off and a truly terrifying movie that gets your heart pounding? We don’t think so. That’s why we’ve explored the science of the scare, with our experiment to categorically find the scariest films for your scary movie night. Our team studied critic’s lists and Reddit recommendations to curate 50 of the best horror films ever made, before subjecting them to our test subjects.”

“Watching each movie in 5.1 surround sound, our panel of 50 people consumed over 120 hours of the best horror movies, each fitted with a heart rate monitor to measure which movies got their blood pumping the most to find the ultimate horror movie.”

The “king of fright night,” according to this particular experiment, is Scott Derrickson’s Sinister, with heart rates also spiking considerably when the panel watched Insidious, The Conjuring, Hereditary, Paranormal Activity, It Follows, The Conjuring 2, The Babadook, The Descent and The Visit. Those films make up the top ten “scientifically scary movies.”

Other movies that made the cut include Halloween, A Quiet Place, The Ring, Scream, The Exorcist, Hush, The Blair Witch Project, Alien, The Thing, Poltergeist and Audition.
