Yeah I hate this one. It's probably my least favorite, too. You'd think with the SCP Foundation being over a decade old at this point, writers would realize you can do some creepy shit with the scientific method, skepticism, and experiments.

For example, let's say a house is haunted. Some science nerds go to the house to start investigating how the house became haunted and they conduct a study the same way you'd study animals in the wild. Lions are still really fucking scary when they rip your colleague's head off when something supposed to protect them didn't work.

It's also one of the ways that unintentionally makes characters unlikable. We, the audience, know the protagonist is experiencing something real. Then having some asshole brush them off (especially a man being skeptical of his wife) just makes us frustrated with the film as a film and not with the plot. It Follows was great because even though only one person could see the monster at a time, everyone who cared about the protagonist believed her that she was experiencing something irregular.
