It’s nearly Halloween season, which means it’s time for things to go bump in the night and for horror movies to give you the heebie-jeebies. But which frightening flick reigns supreme in the scare stakes? We now, incredibly, have an answer – according to science, that is.

So, the scariest horror movie of all time? That would be 2012’s Scott Derrickson-directed horror movie Sinister. Following in second place is Insidious, while The Conjuring, Hereditary, and Paranormal Activity round out the top five.

But what’s the methodology behind the spooky study, commissioned by Broadbandchoices (opens in new tab) for their Science of Scare project?

Simple: put together a list of the top 50 horror movies – across IMDb, Reddit and the like – wrangle some willing participants, connect them to a heart monitor and away you go. Throw in the audience member’s average resting heart rate for each movie compared to their usual resting heart rate and you get the results once you work out the difference.

While Sinister may have topped the charts for this study, it was actually James Wan’s Insidious that caused the biggest spike in heart rates, with one scene generating a pulse-pounding 133 beats-per-minute. Not for the faint-hearted then, clearly.

Now, I’m not a horror person in the slightest – Hereditary messed me up for a long time – but if you want to go all-in this Halloween, you could do a lot worse than this complete top 10...

  • Sinister
  • Insidious
  • The Conjuring
  • Hereditary
  • Paranormal Activity
  • It Follows
  • The Conjuring 2
  • The Babadook
  • The Descent
  • The Visit
