The Philosophy of Pseudoscience
In my encounters across the internet looking for interesting topics related to art, philosophy, and science, I've come to realize there's a whole bunch of pseudoscience out there, which I've decided to make the topic of this post. One of the more prevalent and interesting examples is the popularity and general interest in the metaphysical and healing properties of crystals. To be upfront, I don't subscribe to any of these types of beliefs, nor find any of them at all plausible. That being said crystalline structures and other organic gemstones are abundantly interesting as scientific and artistic objects of study (at least to me)> They're wondrous examples of the way nature self organizes out of chaos, and illustrate the intersections between physics, information theory, and theories of life. That in itself understandably seems almost supernatural. I still believe in asking big "what if's" as a means of shifting our perspective on real world problems (Philosopher Daniel Dennett would call these “intuition pumps”), but where issues arise is when we make specific claims to reality that are not in any way measurable or testable, and try to construct a hard science based on those claims. That being said, I think crystal healing provides a good demonstration of different ways in which pseudoscience operates and proliferates alongside science.
Most of the pseudoscientific systems that are built around crystal healing revolve around some sort of abstract notion of energy that flows through all living things. You’ll hear it referred to as the Chinese “Chi” or “Qi”, or of the Hindu “Charkras”, or the more credibly scientific “energy grid” or “life force”. In any case these terms appeal to established belief systems in both science and religion. Rhetorically, this is referred to as a “call to authority” and upon any further examination of the content of these words, we find them vague or unmeaningful. All pseudoscience relies heavily on jargon to create false credibility and disguise otherwise empty concepts. Not wanting to be perceived as naïve or unintelligent, we simply nod our heads instead of asking for an explanation; like when a friend asks you if you’ve heard of a band you’ve never heard of, and you say yes out of fear of social ostracism. Contrary to its more esoteric uses, in physics energy is an observable and measurable force, which comes in units such as the Joule, Newton, watt, or calorie. What then is the unit of measure for life force, or chi?
But what about all the folks that swear by crystal medicine? Surely they can't all be misinformed or deceived? Isn't there some tangible, measurable effect that they are all feeling independently of each other and of the rhetoric surrounding crystal healing? Yes. It's called the Placebo Effect, in which an ineffective treatment yields measurable improvement in a patient's condition simply because he or she believed that the treatment works. The placbo effect can be quite powerful, one Harvard study found that patients who were told that their medicine was ineffective still showed a measurable improvement in condition. Having felt a tangible improvement in their health seemingly as a result of magic crystals, proponents of crystal healing are led into what is known into a cognitive bias, in which one interprets reality based one’s beliefs or wishes. More specifically it’s a case of confirmation bias, in which an observer focuses myopically on evidence that supports his or her claim, while ignoring or discrediting contradictory evidence. At this point belief in crystal healing becomes a type of self-reinforcing feedback loop.
Beside discrediting the metaphysical healing properties of crystals, I think it's valuable to consider why ideas like these become so popular in the first place. One possible explanation is societal. The alternative medicine industry has grown incredibly in recent decades, and is now valued at over 30 billion dollars annually. "Alternative Medicine" itself is an incredibly broad term that encompasses everything from health foods, vitamins and supplements, herbal medicine, yoga and exercise, homeopathy, acupuncture, chiropractics, marijuana and psychedelic therapies, the list goes on. It's a cultural movement as much as a medical one.
That being said, against the backdrop of the immense, uncaring, and corporatized health industrial complex, alternative medicine posits itself as both humane and attractively counter-cultural. It’s this sort of institutional alienation that fraudulent science thrives on. Consider Kevin Trudeau, the infomercial king and convicted fraud who sold over five million copies of his book titled “Natural Cures “They” Don’t Want You to Know About.” Note the vague and ubiquitous “They” in the title. Yes, it’s really in quotations.
Not to say that some of these practices are not valuable. I'm completely supportive of the medical benefits of diet and exercise, meditation, even the potential for psychedelics to treat PTSD, depression, and addiction. Additionally, there are broad aspects of the movement that are quite positive; the focus on the body and health as a whole, rather than as a series of isolated symptoms. Or the emphasis on diet lifestyle and exercise rather than medication or surgery. It could be appropriate in some situations that healthcare shouldn't be limited institutional medicine. I think it's plausible to have a healthcare system in which institutional and alternative medicine temper and complement each other, as is the goal of the integrative medicine movement.
A more general explanation for popularity of pseudoscience relates to science itself and the sometimes blurry boundaries of the field. To philosophers of science, this is referred to as the problem of demarcation, or the problem of distinguishing what is valid scientific reasoning and what is not. The austere position would say that verifiability, the ability to either prove or disprove a claim by observation, is the only standard of scientific practice. This was the position of the logical positivists, and of the Vienna Circle. Unfortunately, this position throws much of contemporary science out of the window. Verifiability falls short when it comes to relativistic phenomena, as when two observers from different locations see the same event differently. Which observation is correct? Similarly, in the realm of quantum mechanics, it’s not that light is necessarily both wave and particle, but it can be described as either one or the other in a satisfactory way. So which one is it? This is referred to as a equivalence of description in which two models describe the same phenomena just as well.
A trickier problem is the misuse of theoretical scientific entities. This is especially true in light of the general public interest in topics from contemporary science. Recent times have seen an explosion of interest in things like black holes, string theory, and parallel universes, which have been widely incorporated into science fiction and popular science entertainment. While this is encouraging, the tendency of popular science is to focus on the entertaining and interesting aspects of these entities, and does little to elucidate them rigorously. Consequently, in this climate it is easy for charming personalities to align themselves with popular science, and draw wildly incorrect conclusions that otherwise look legitimate. To quote a New York Times Article by Massimo Pigilucci and Maarten Boudry:
"Philosophers of science have long recognized that there is nothing wrong with positing unobservable entities per-se, it's a question of what work such entities actually do within a given theoretical-empirical framework. Qi and meridians don't seem to do any, and that doesn't seem to bother supporters and practitioners of Chinese medicine. But it ought to."
This is the crucial point that advocates of crystal healing and the like miss. In the end there is no sharp dividing line between valid and invalid theoretical entities, between science and pseudoscience, but this certainly any a free pass to any proposition you like. There are plenty of pseudoscientific theories, personalities, and products that take creative license with the more exotic flavors of scientific theory and run amuck with them. A perfect example are the range of "zero-point energy" devices, which claim to heal and restore the body with fields of energy discovered by quantum physics, or "Quantum Jumping" Bert Goldman's self help system with a sci-fi twist that allows one to meet and learn from alternate versions of themselves in parallel universes. Note the characteristic vagueness, jargon, and calls to scientific authority associated with both.
Granted, pseudoscience has been around as long as science, probably longer. What seems to be a unique problem to the present is that science itself is becoming more abstract and removed from direct observation and provability, and the criteria for truth is becoming more abstract as well. In a secular, postmodern society, science (and pseudoscience) are occupying more space in our imagination traditionally held by religion and philosophy, perhaps more than it should. It is in this space that crystal healers, zero-point wands, and quantum jumping slither in alongside more meaningful attempts to explain reality. Perhaps this is symptomatic of scientific illiteracy in our culture, or our ability to teach sound reasoning in general. Or perhaps the persistence of crystal healing suggests that some of the major problems for science in the 21st century are going to be those of self definition and demarcation. In either case, philosophy of science is going to be an indispensable tool for understanding and parsing out pseudoscience.
In the meantime, hold onto your crystals, it's going to get weird.
