People will be like "yes parapsychology has been studied for hundreds of years and never once had a conclusive shred of evidence to support it. Yes it's been studied at very prestigious institutions and universities. And yes every single supposedly successful trial has turned out to be either a hoax, a mistake, or outright fraudulent. And yes every single positive result has completely vanished when more stringent methodology was used. And yes improvements in technology have only ever made supernatural claims easier to disprove. And yes even the most famous and confident of psychics mysteriously choke up every time they try to pass even a mildly hoax-proof test.
. . . but it's totally real and scientists are just too narrow-minded to accept that there's something beyond their worldview :/"
