If you are a fan of horror movies like me, then I am sure you always hunt for those which are the scariest. However, as fear can be subjective, it is almost impossible to find which, of all the horror flicks in the history of cinema, is the scariest. But when there is science, there is always a way to find answers. So, a company has recently conducted a scientific study to find the scariest movie of all time.

Now, for the big reveal, the scariest movie of all time, according to the study, is “Sinister”, which released back in 2012. Well, wasn’t expecting that, were you? Even I did not expect Sinister to be the scariest movie of all time.

The researchers also discovered that “Sinister” gave the participants an even scare throughout the movie. However, the scene in which the heart-rate of most of the participants rose to 133 bpm was from the 2010 horror flick, “Insidious”.
