Just in Time for Halloween: The 1 Scariest Horror Movie Ever, According to Science - Showbiz Cheat Sheet

According to Forbes, broadbandchoices conducted a study to determine the scariest movie of all time once and for all using something called the “Science of Scare Project.”.

To find the scariest movie, broadbandchoices selected 50 random people of all ages and instructed them to watch 100 hours of scary movies.

Since there wasn’t time to screen every horror flick ever made, the study creators focused on the top 50 highest rated scary movies on IMDb, Rotten Tomatoes, and Reddit.

Using their logic, the movie that elevated heart rates the most must be the scariest.

Watching the horror flick made participants’ heart rates increase 32% on average.
