Just because you can’t reproduce something in the lab, doesn’t mean it’s not happening in nature.
Psychic abilties may not able to be flicked on/off like a lightswitch on command.
Genuine preminitions may come without warning, (somewhat) spontaneously, or they may require a genuine need, someone or something in danger or distress, in order to activate them.
Not everything that does exist needs to be proven to scientists in a lab, it could be some of the most important phenomena in life are too intricate, delicate and mysterious to replicate in a clinical, sterile fashion, but nonetheless we may be able to prove them to ourselves.
How animals behave in captivity or the lab and the wild can be two very different things.
For example it’s notoriously difficult to get pandas to breed in captivity, it rarely occurs, yet of course it’s occurring in the wild, likewise predicting things beyond chance may rarely occur in the lab, but that doesn’t mean it isn’t happening more frequently outside of it.
Scientists cannot perfectly reproduce all the variables out in nature or society in the lab, there’s too many of them, and just one or two missing ones could completely botch the experiment.
If the spiritual worldview is predicated on the idea that consciousness, will, intention is everything, or a lot, as opposed to matter, than yes of course the intention of those conducting the experiment could adversely interfere with it, especially since this phenomena would be entirely intention based, not material based, I don’t see that as a copout or excuse at all, it’s just keeping in line with their fundameantal beliefs about the nature of reality.
I’m not saying we should trust psychics or our own premonitions if we happen to have any, but myself I’ll give them and it a chance, be open to them and it at least, perhaps even believe in it a little bit more than not, that there’s something to it even if it’s not exactly what they think it is, and perhaps I’ll be pleasantly surprised.
Scientists may be rigging experiments too, most scientists are atheists and aspiritual, many may even be antitheists, so perhaps they’re downplaying the results.
When a team of researchers are Christians or being funded by Christians or some other religious or spiritual organization, other scientists are quick to claim the experiment was biased and dismiss it offhand, but what if the majority of scientists who design the experiments and interpret the results are just as biased against this phenomena, they may not be wiling to give it a fair hearing.
