Can you give me an example of "psi" I can directly witness in everyday life without it being a subjective judgment? Say, something I could observe by midnight tonight?
Yes, but Johann, all sorts of things that were not obvious and indisputable nonetheless left a scree of traces across our physical experience. Consider all the diseases we didn't comprehend the origin of when we were not capable of detecting micro-organisms. Nevertheless, a gunshot scatter of symptoms from these diseases were debilitating and killing numerous people. My question about "psi" is...where is this similar scatter of symptoms as actually registered in world phenomena? Where can one go to see it happening or into what (physical) system can one bend one's observation to see it happening, where that happening does not itself become rhetorical to the observation process? If the only real evidence of microbes was that we saw things wiggling under microscopy, then this should give us pause for whether the hypothesis of "microbes" actually does anything.
Just as diseases, indisputably evident, were not
per se supportive of the existence of bacteria; shamanic practices, religious claims of mystical experiences, the proliferation of magical and occult beliefs in human cultures, seemingly inexplicable coincidences and forecasts, and a whole host of other phenomena—all of them there for anyone to witness—are not
scientifically supportive of psychic experience. What psi and bacteria share in common is that both must go "under the microscope" for us to have confidence that they exist. Microbial science uses optical magnification to bring into stark relief entities that we would normally never see; psychical science uses statistical magnification to draw out otherwise imperceptible signals hiding in the peaks and valleys of probability.
The bacteria you can perceive unaided by tools of amplification, such as the
namibiensis, commonly more than .2 mm in length, can probably be counted on one hand; sightings of such species did not occur until long after bacteria, generally, had been accepted as real organisms (and even if such sightings had occurred, it is unlikely they would have been accompanied by identification). Similar things may be stated for psi phenomena; it is possible that traces of psi lie scattered across all human cultures, even in our daily lives, and—like electromagnetic fields before Faraday, or radio waves before Hertz—surround us without our recognition.
It is equally possible that psi does not explain all, or even most, of these ostensibly similar things; bacteria were certainly identified before viruses, but they did not cause measles, polio, cancer, or even the common cold. In concert with other factors (such as human psychology and neurobiology), psi may be only part of the explanation for "the paranormal".
In our struggle to comprehend the complexity and nuance of the natural world, we should discard no tools that may aid our understanding. It is tempting to apply the methods of medieval scholasticism, relying purely on argument and what can be deduced from the senses, but the age of such incremental advance is long past us. Laymen may be intimated by and untrusting of technical scientific methodology (without clear technologies developed from them), but this is just how it is; statistics, mathematics, physics, and chemistry are not things everyone can do, without long and intense study, and that is what make them valuable. In my opinion, the person who claims that psi should be obvious; that casinos shouldn't exist because of psychokinesis, or telephones because of telepathy, is operating at the intellectual level of the man who doubts the existence of climate change because it is not warm everywhere—these arguments deny the efficacy of science by privileging personal speculation. I have seen you advance very similar contentions (at least to the first); you may want to consider what the full acceptance of your philosophy entails.
In sum, I have stated my position:
a priori arguments against psi are, at this point, highly unpersuasive.
