Psychology professor Etzel Cardeña wrote an article last year for American Psychologist that purports to show evidence for parapsychological phenomena. To bolster his case, Cardeña referenced quantum mechanics, the theory of relativity, and the block universe hypothesis, a model in which past, present, and future exist simultaneously.
As a counter to Cardeña’s claims, psychologists Arthur Reber and James Alcock penned an essay for Skeptical Inquirer, in which they opined that Cardena’s effort was the latest in a 150-year failed attempt to legitimize parapsychology. There reasons for these failures, they assert, is that every claim made by psi researchers violates fundamental principles of science.
Reber and Alcock did not examine Cardeña’s data since they considered it irrelevant. As a comparison, they noted that pigs cannot fly, so any data that points to swine being independently airborne would be the result of “flawed methodology, weak controls, inappropriate data analysis, or fraud.” They focused not so much on Cardeña’s claims but on parapsychology’s in general.
One reason they did so is because, as they noted, parapsychology is a faux field that hasn’t progressed since its inception in the 1880s. Then, as today, the overarching theme is that there is an unidentified, untraceable “more” to our universe beyond atoms, molecules, senses, people, and planets. This grandiose claim comes with zero testable or empirical evidence.
One scientific law that would need to be violated for parapsychological claims to be true is causality. Effects have causes and, with psi, there are no causal mechanisms, and none have been hypothesized. More relevant, there is no consideration of if the supposed psi effects have one causal mechanism or many. There is also the issue of inconsistency. The skeptical duo ask, “If psychokinesis affects the roll of dice in a psi lab, why not at craps tables? If telepathy exists, why are our brains not constantly abuzz with the thoughts of those around us? For allegedly existing now, the future only shows up in parapsychology lab tests.”
Then there are violations of Time’s Arrow. Parapsychology asserts an ability to warp time, most glaringly when involving precognition. Psi researchers regularly love to drop the term “Quantum Mechanics” and they often do so when referencing the entanglement effect. This in an example of pseudoscience, where scientific terms are used, albeit incorrectly, to try and lend credence to a position. Now, it’s true that two spinning particles separated in space are entangled since the state of one is simultaneously aligned with the other. But this does not equate to a reversal of time; there are merely concurrent effects.
“The notion that the strangeness of the quantum world harbors an explanation of the strangeness of parapsychology is a false equivalency,” Reber and Alcock write. Indeed, this is the secular version of “I don’t know, therefore a god did it,” with quantum mechanics replacing the instigating deity.
Quantum mechanics is hellaciously complex and probably less than one percent of people fully comprehend it. That leaves ample room for confusion and in this large area is where pseudoscientists like Cardeña operate. But there’s nothing in quantum mechanics that would validate or necessitate paranormal occurrences.
Yet another law that would need to be violated for parapsychological claims to be valid relates to thermodynamics. Again, consider precognition. For the future to impact the present, this would necessitate violating the principle that energy cannot be created or destroyed in an isolated system. The act of choosing a playing card, a common technique in psi research, involves neurological processes that involves measurable biomechanical energy. The choice is presumed to be caused by a future that, having no existential reality, lacks energy.
Finally, we have an Inverse Square Law violation. In supposed telepathy, the distance between the two involved persons never seems to be a factor. This is inconsistent with the principle that signal strength falls off with the square of the distance traveled. Psi researchers again employ the entanglement effect as a possible explanation, but within quantum mechanics, there is no transmission of energy between the separated particles, they are merely entangled.
In conclusion, if psi effects were genuine, they would have already landed fatal blows to vast blocks of scientific knowledge.
