There's no such thing as "scientism." That's a weasel word that woo-promoters use to discredit science when it conflicts with their ideology.
The claim that everything is measurable by science and that anything which isn't, i.e. religion and philosophy, is a delusion, is a common one here.
Science can detect anything we can detect with our senses. By definition, anything humans can detect that actually corresponds to external reality is being detected by our senses, because that's what senses do - they detect things in reality.
Thus, experiences of "detection" that are not via the human senses must, therefore, be inventions of the mind - delusions. Sure,y ou'd like to hold out the idea that "there's more than what we can sense", but if we can't sense it, how would we know about it? How would we generate ideas about it that would be anything but guessing, and therefore immediately false?
If there's something "out there", but we can't generate accurate ideas about it, what's the point in holding the door open when nothing good can come through?
And moreover - what makes you think that
science doesn't provide a nearly endless supply of "more than we can see"? It seems like science has illuminated a hundred invisible worlds, some as close to us as our skin, and the advantage science has is that those new worlds
are really real, not the fancy of religion or philosophy. And we can generate, through science, through our senses, accurate information about those worlds.
Surely generating accurate information is a more noble cause than generating flights of fancy. How on Earth can the mysteries of the universe
we know about not be enough for someone? I just can't understand it. Why try to gild the lily? The universe is already vast and weirder than you can imagine. Anything you could
make up with your little human mind - be it religion, or God, or spirituality, or the Force, or what have you - must pale by comparison to
what's really out there.
Science is the gateway to what's really out there. Your imagination, your gut feelings, can't take you nearly as far - they can't take you anywhere but where you already are.
I've seen estimates that 50% of Americans claim to have had a supernatural or paranormal experience.
Well, one in 4 Americans had a diagnosed mental illness in the past year, and one in four of
those had a
serious mental illness, like schizophrenia.
Also 50% is about how many Americans question the evolutionary model and promote some kind of creationism, incidentally.
It is not true that all research ever done on the subject has reached negative conclusions.
It is true. There has never been a paranormal experience that has survived rigorous inquiry.
Maybe part of the problem lies in the methodology of the studies.
In almost every study the proponents of the specific woo under inquiry are worked closely with, to ensure that the methodology doesn't interfere with the test. If even the specific proponents of the paranormal signed off on the methodology, what possible objection can you raise?
Do you think they will all back down and say OK, it was just a mistake, or I must be delusional?
A lot of them do, when faced with the evidence. A fair number of them say "oh, I guess I
didn't have a paranormal power I could use at any time. I guess it was just wishful thinking."
