When it comes to horror films, everyone probably has their favorite. Whether psychological horror, slasher, or other – if you ask friends about the scariest movie they have ever seen, the answers will be very subjective. However, scientists wanted to find out exactly and conducted a study to measure the physical reactions of participants when watching horror films.
The heart races, the breath catches – some people who have seen a really good horror movie may be familiar with these reactions. To find out which horror films raise the heart rate the most, broadbandchoices.co.uk conducted “The Science of Scare Project.” For the second year running, the researchers wanted to find out which horror films frightened the 250 study participants the most.
Overview
In total, participants had to watch 40 horror films. The selection of films was based on lists from film critics and suggestions from the Reddit community. The researchers measured how much the heart rate or pulse rate changed while watching. The average value of the test subjects at rest was 64 beats per minute (BPM). The higher the average increase, the scarier the movie is considered.
The results produce the following top 30 scariest horror films on a scientific basis:
1st place: Host (2020), +24 BPM
In first place is Host by director Rob Savage. The film was not only released during the coronavirus pandemic but also indirectly dealt with it. Six friends book a séance with a medium. This takes place via Zoom during the lockdown. The plot makes you smile at first. However, the movie itself quickly turns creepy with the appearance of a ghost and the fear of dying.
2nd place: Sinister (2012), +22 BPM
Sinister was still in first place last year, but the story about crime novelist Ellison Oswalt (Ethan Hawke) still promises quite a lot of creepiness. He specializes in true crime cases and wants to solve them. One day, he finds a box of videos. What he sees on it leaves him speechless and takes his current case a step further.
