Theories derided from "slothful induction", such
as Periodolia and "Mass Hysteria"....
It's all in our minds!!! And when it strikes in numbers,
"Mass Hysteria"!! How convenient.
This is the Fortean misconception of science, that science simply must be able to explain all things immediately otherwise it collapses like a deck of cards. Science can't explain everything people think they see or everything people claim they see. Many classic Fortean incidents like raining fish were eventually explained.
What would average man have said ?
You're crazy,there is no proof of that,at all .
Actually no one claimed that because no one knew it. This is a strawman argument.
That must be why man is no longer creating new technology and science has been abandoned. Yep, we didn't send a probe to Pluto. We've stopped sending probes to Mars. New space telescope? We have Hubble just like God does! New supercoliders? No thanks, we now know absolutely everything about subatomic particles, just like God does.
The means to measure these things already exists. We have cameras and audio recording equipment and scientists have in fact used these to measure the paranormal. They have shown that paranormal experiences generally have normal explanations and that regular paranormal phenomena tend to immediately stop when such measuring equipment arrives.
It's interesting that you claim that the paranormal exists while also admitting we have no way to verify it exists at the moment. Scientists don't jump to conclusions like that.
Actually it only took Anton van Leeuwenhoek a few minutes with a microscope to discover red blood cells. It greatly helped him that they existed.
