Earthing Unearthed

Sometimes I feel disconnected. It’s almost as if I have been traveling on a highway all my life, largely unaware of the myriad roads that emanate from it. Unaware of the different coloured horizons that have been hiding out there all along. Or is skulking sometimes a better descriptor? Every so often I come across a concept so… bizarre, that I wonder how it even survived long enough to acquire a name. ‘Earthing’ caught my attention immediately.

I feel I have to explain that I don’t go looking for these things, but in the spirit of full disclosure I will confess to being a one-time member of the Skeptics Society –one time, I suppose, because the time constraints of a busy medical practice required that I relinquish at least some of my addenda. Now, retired and awash in compensatory time, I dabble once again.

‘Earthing’, for those of you as naïve as myself, is the act of walking barefoot –not just on the beach or over the soft grass of a lawn, however. It is to soak up earth’s energy fields previously denied to you –blocked, in effect- by your shoes. These energy fields apparently supply free electrons replete with many health benefits. Shoes, as disruptors, ‘[…] allegedly cause inflammation and autoimmune diseases, circadian rhythm disruptions, hormonal disorders, cortisol disorders, heart rate variability problems, arthritis, herpes, hepatitis, insomnia, chronic pain, exhaustion, stress, anxiety, premature aging […].’ Uhmm…

How could I have journeyed so far along the trail of years and not heard this coming up behind me? Call me old fashioned, if you will –or just ‘old’, perhaps- but I would still feel more comfortable if there were credible, corroborative and objective evidence to substantiate assertions before I even decide to consider them -let alone examine them seriously… Anybody can claim things, but as Carl Sagan once declared: ‘extraordinary claims, require extraordinary evidence’.

Now I have to say that just because something seems counterintuitive, I don’t think it should be simply dismissed out of hand. Paradigms do shift, after all. But they still require critical analysis; it is not enough to suggest that, as in the case of homeopathy, for example, any attempt to verify it destroys the field in which it exists. Nor are statements like, ‘It may be that our connection with the earth carries information, helping align us with the greater network of intelligence of our planet.’ either provable, or refutable –the famous philosopher of Science, Karl Popper’s belief that what distinguishes science from pseudoscience is its potential for refutation. For example, to say that all swans are white, only holds until a black one is found. The assertion –if properly attested by observations- is scientific in that the demonstration of even one black swan is able to refute it.

But, academic considerations aside, there is something troubling about ‘Earthing’ and its ilk. That something like this arose at all is, I suppose, a function of the random accretion of isolated and misunderstood bits and pieces of our complex modern world that are only describable in metaphor –as in, say, electrons are the carriers of electricity. True, as far as it goes, I guess, but misleading if taken as literal. Maybe some shoes –all shoes?- may block electrons… But so what?

Just try and understand the electric fields on the earth and in the atmosphere. As an example, a description from (shudder) Wikiversity: ‘The Earth is negatively charged, carrying 500,000 Coulombs (C) of electric charge (500 kC), and is at 300,000 volts (V), 300 kV, relative to the positively charged ionosphere. There is a constant flow of electricity, at around 1350 amperes (A) [approximately 1100 A], and resistance of the Earth’s atmosphere is around 220 Ohms. This gives a power output of around 400 megawatts (MW), which is ultimately regenerated by the power of the Sun that affects the ionosphere, as well as the troposphere, causing thunderstorms. The electrical energy stored in the Earth’s atmosphere is around 150 gigajoules (GJ). The Earth-ionosphere system acts as a giant capacitor, of capacity 1.8 Farads. The Earth’s surface carries around -1 nC of electric charge per square meter’. Do you see why most of us non-experts are dependant on metaphor? And why explanations such as this about ‘constant flow of electricity’ unaccompanied by suitable annotations may lead to some unfortunate and perhaps misguided applications?

On the other hand, I think that trying to dissuade gullible adherents requires some tact. Attempts to ridicule them by referring to the authors of a book on the subject: Earthing. The most important health discovery ever? and saying ‘None of the book’s authors is a physicist— it shows.’ is just ad hominem. Or suggesting that scientific credentials are not available: ‘The studies were not published in mainstream journals. They involved small numbers of subjects and usually failed to use any controls.’ While true -and to those of us with any acquaintance with how science works, compellingly obvious- it likely fails to convince those who mistrust the scientific paradigm and its lack of certainty to start with. And it may antagonize them to the point of utter rejection of any meaningful dialogue. It becomes another us-and-them standoff.

So, what to do? Tolerate or proselytize? Divide and conquer? Provoke and legislate…?

Perhaps it’s my age, but I’ve seen many fads arise and then dissipate like waves on a beach, with any one of them having about as much individual significance. Think of alien abduction, recovered memory therapy, pet rocks… Each seems to have a brief super nova-like appearance, and is intriguing for a while, and then, when a new star is born, interest flags. Social media may extend the lifespan, perhaps, but novelty is usually trump for those attracted to the fringe belief realms. I’ve learned not to obsess on what I consider the irrational; I will attempt to educate, but not to the point of taking arms against a sea of trouble and by opposing, ending them –as Hamlet would have us decide. If they are not harmful, then they will, as certain as the tide, recede.

In the turmoil of this uncertain world I think we all try to find secure and novel refuge, and when the storm has passed, set out again. It’s what we do –Shakespeare again: ‘Wise men ne’er sit and wail their loss, but cheerily seek how to redress their harms.

Earthing, with benign neglect, may itself be unearthed…



A Pink Elephant in the Room?

You could see her waiting in the wings, peeking around the curtain, anxious for her debut on the public stage. And what a buildup; the opening acts pretty well guaranteed her a receptive audience -one that would assume that anything less than a full symphonic orchestral introduction and a dais at centre stage would be discrimination. Gender imparity. No, her time was already too long delayed; everybody had come to see Ms Pink Viagra perform –maybe even out-perform what had come before.

Well, okay, I understand the problem –I even suspect I understand the parity issues: it seems unfair to help the man with sexual dysfunction (read erectile dysfunction) while appearing to believe that any problem in the woman is just psychological… Or his fault. Beyond the Pale, in other words. The current situation is a vexing one to be sure and the answer is clearly not an easy one. But I’m hoping that we don’t merely end up prescribing medication alone for an issue that is almost certainly multifactorial.

There was a helpful, albeit preliminary, article on the subject in the Canadian Medical Association Journal this December:  At the time of publication, the American FDA had recently approved a drug (flibanserin) for the treatment of ‘acquired, generalized hypoactive sexual desire disorder’ in premenopausal women. The concern, in the Canadian context at least, was whether any company approved to market it would be able to adhere to Canadian law in advertising it: ‘direct-to-consumer advertising is not allowed in Canada, but direct-to-consumer information campaigns are legal’. One of the problems is the quality of evidence for the information supplied. For example, in the USA, the company selling it claims that ‘hypoactive sexual desire disorder affects as many as one in three women in the US’, whereas ‘reliable and independent scientific data show that only about 1 in 10 women experience distress as a result of their low desire and thus have the condition’. Suggesting, of course, that low desire does not always need to be treated; and therefore the corollary that low desire in either partner is not necessarily pathological…

I’m also concerned about the drug’s promulgation in the cause of equivalency. Fairness. If information about a product is what is allowed by law, surely neutral presentation of all that information is what was intended -expected, if not required. As the article suggests: ‘Bias is introduced if emotive campaigns that are not linked to strong evidence underpin the provision of information.’  And it goes on to say, ‘What about asking the more pertinent questions of whether the existing evidence can tell us if the condition really exists or whether drugs are the only response to a “dysfunctional” level of sexual desire?’ Indeed, perhaps the entire subject of sexual dysfunction in either sex requires a more critically based analysis.

I have to admit that, as a general gynaecologist, I have always felt very uneasy and ill-equipped for dealing with the subject of sexual dysfunction. It’s not that I find that it is embarrassing -I don’t (although the patients usually do); and I don’t mind that it is time consuming (my accountants not withstanding); it’s not even that it contains an undercurrent –often well disguised and overtly denied- of recrimination, blame, or guilt (although it can be all of those). No, I suspect that it is rather that the solution to the problem is seldom straightforward or easily solved. And, unlike an infection, it may require more than a pill to cure. It seems to me that the answer often lies with both parties –and each comes to the table with different perspectives. Different interpretations… Different appreciations of the issue, for that matter. Occasionally it may respond to empathetic listening, and the provision of impartial information along with counselling; more often it requires a multidisciplinary approach , or at least an expertise beyond that of the average practitioner, however well-intentioned. And that may be difficult to obtain in a timely fashion.

But as with depression, for example, it is often so much easier for the uncomfortable and busy practitioner to reach for a prescription pad after a brief hearing, and a subsequent cursory analysis of the complaint. And even if the medication, in the cool, reasoned glow of retrospect, turns out to be more of a placebo than a targeted and specific cure, well, that’s better than nothing… Isn’t it?

Maybe it is, but is it an example of critical thinking? Evidence-based medicine? Is it really the result of an honest and respectful consideration of the problem? If the condition is indeed often multifactorial, shouldn’t the treatment be that as well? I’m sure that the directions on the probably-pink package will make that perfectly clear, though… Right?







The Polarization Bias

Okay, I have to admit to living an unbeknownst lie –unbeknownst to me, at any rate. Sometimes it is easy to coast, to accept help where it is offered and feel almost foolishly grateful for suggestions that foster the dependence. Advice is seductive, guidance addictive. But more importantly, it is insidious. Critical thinking -critical analysis- suggests that we process whatever information we are offered by considering its validity when compared with other sources, other viewpoints, other contexts. It is what we should do; it is not what we usually do. Time constraints, biases, laziness –they all conspire to let us float on the tide. Drift.

I suppose my awareness of the current may have started when I was casting about for a book to read. Like many of us, I have a passion for reading that is naively open to recommendations. The online Amazon book store is an almost limitless cornucopia of books. And when you click on one, a section appears just beneath your choice that says: Customers who viewed this item also viewed… And a list of similar books on similar subjects is just a click away: a topic-specific, yet unrequested bounty spilling onto the screen. And all with seemingly different approaches but eerily similar viewpoints to the book you’ve chosen. A coincidence? Or a recognition that you have a particular worldview whose advocates you are more likely to read? And buy.

At first, I was both pleased and amazed that Amazon could find so many different authors and topics that I found compelling and place them before me like a waiter with a dessert tray. So easy to choose from only what is offered –too easy… What I initially thought of as a diverse array of well-considered opinions, I began to realize was an artfully arrayed selection that fostered my already-held biases. A compass that always pointed north, no matter the coordinates.

I suspect that most of us, even offered the choice, would find no compelling reasons to change allegiance, or flirt with opinions we have been taught to mistrust. We feel uncomfortable accepting that the opposition feels the way it does on grounds that are equally persuasive for it. Rather than being open even to thought-provoking alternative ideas, we rust into positions that further restrict our ability to move.

But what if the news we so avidly ingest nowadays could be similarly sorted to our tastes and presented to us as a fair representation of what is really happening? How would we know of the manipulation? How could we become aware of the slanted viewpoint when it so closely agrees with our own –when it is what we want to hear? Confirmation bias is difficult to resist even at the best of times.

I hadn’t realized that many people actually read those snippets on Facebook that purport to inform. I had thought most of them were not terribly well disguised ‘infomercials’, but perhaps that is my bias -the boreal plain to which I am unwittingly confined. But that our serving of news should be chosen for us according to our likes and dislikes is anathema. And that our meal of information should be expurgated and mashed into a small, more easily digestible aliquot of words smacks of propaganda. Control. Handling… I would like to digest unchewed information in my own way, thank you. I can deal with heartburn; I’m not good with starvation.

The dilution of mainstream media and its as-yet relatively unfettered ability to pretend to present both sides of an argument is worrisome. Similarly, the accretion of our sources of information into a few huge monolithic blocks with their own interests to serve is dangerous. Especially when they presume to know what opinions will keep us quiet.

“Let every eye negotiate for itself and trust no agent,” says Claudio, in Shakespeare’s Much Ado About Nothing. Bravo!

Critical Thinking and Bullying

A few weeks ago, a young woman came in to see me to have her first Pap smear. While I was taking a routine sexual history, she admitted she had recently been bullied online. I’m not even sure how the topic came up, but she didn’t seem very upset, so I asked her about it.

“The guy was a real dick,” she said. And when I asked her how she reacted, she merely shrugged. “Everything he said was false and all my friends should know that… So I ignored him.”

“And did he try it again?” I admired her reaction, but I have to admit I was curious.

She liberated a beautiful smile and shrugged mischievously. “Yeah, once… But then I guess he gave up.” She allowed her eyes to roll upwards comically. “My mother always told me to ignore stuff that wasn’t true.”

It got me thinking about why some people are able to withstand that kind of thing, while others succumb. I don’t pretend to know what motivates bullying, but I do suspect my patient was taught an effective remedy from an early age.

Critical thinking is a way of examining a statement or assertion in order to understand the background and motivating factors for its existence. Its credentials, in other words. It is a way of distancing oneself from the message and analysing everything that went into making it before either accepting or rejecting its content. Also, it is a way of avoiding confirmation bias –reading or assessing only those issues with which one already agrees, rather than sampling a variety of views and thinking of them as interesting, but as yet unproven assertions.

In important ways, this is what Science does: everything is open to checking and possible refutation. Nothing is spared re-examination. Carl Popper, the philosopher of science, suggested that an assertion, a theory, must be worded in such a way that it is testable, otherwise it can not be generalized -or as he would put it, it can only be considered scientifically valid if it is falsifiable- ie checkable. Anything else is merely an opinion -as, for example, the statement ‘Red is the most beautiful colour’. It is not testable, and therefore certainly neither provable nor undeniably valid. This is the first simple rule of thumb we can teach: we must help children to parse input.

Young children tend to question everything- it is how they learn. But in the very young –under, say, six or seven years of age- they often use magical thinking: cause and effect are not necessarily demonstrable either by reason, or even observation. Past that age, however, they begin to understand agency. Causal chains. It is a good time to introduce the concept of validity: was something really a result of an action, or was the action merely associated in time or location so as to seem to have influenced it? And although this is a good first start it is nonetheless one that is not necessarily intuitive. For example it would be tempting to assume that a boy running past a crying girl had done something to her -it might fit with a previous experience. But maybe he was running to catch a bus and it was a coincidence that the two were in the same area at the time she was crying… It requires more proof. More examination.

The habit of questioning things before accepting them can be taught. It can be made into a reflex before reacting. But it needs to be developed early, before the temptation to interpret hastily, or even reciprocate mindlessly, has become entrenched.

The basic elements of simple logic can be taught. For example with inductive reasoning, one attempts to generalize from observations. So if all the crows you have ever seen were black, then you might conclude that all crows are black… Until somebody sees a white crow that is… It is falsifiable, in other words. Most taunts are of that variety -and with practice, easily refuted.

Or even with deductive reasoning which works the other way -from the general to the particular: All men are mortal; Socrates is a man; therefore Socrates is mortal -the classical example. But it only works if the premise is valid (ie. that all men are mortal). And it may only be somebody’s opinion that it is valid…Once again, is it like that example of red being the most beautiful colour? We can all be taught to analyse things like this. We can all be taught to be wary of unsubstantiated statements. Rumours. Gossip. Taunts…

And the critical thinking approach can even apply to actions as well as assertions. A simple example: a young girl is hit by a snowball and another child, a boy, is standing nearby in a group of boys and staring at her. Was he to blame? Did he throw it? Maybe, but without further analysis, further investigation, there’s no proof. No reason to jump to a conclusion. Why did she think it was him? Is her reason based on anger, or is it justified..? This is the basis for the idea that a person is innocent until proven guilty… It is an important concept to inculcate in the growing mind. It is a way of distancing oneself from the action, no matter how provocative, and setting it aside until it has been analysed further. We all judge input, we all react to issues we encounter. And some things do require an immediate response. But it’s how we come to the judgement, how we analyse the data –how we react- that is critical.

You can see where this is leading I suspect: bullying. Bullying -whether on the playground or online, whether by deed or word- has the advantage of unfair leverage only if the process is unexamined. Only if the person being assailed is not used to subjecting taunts to the same questioning. Stepping back, if only momentarily, and processing the information. Checking it. Falsifying it. Refuting it -like my patient was able to do.

A difficult thing to do in the moment, for sure. But without any experience in dissecting assertions –deconstructing them, as PhD candidates are fond of saying- there are only reactive emotions. Victimization. Loss of self esteem that could and should withstand the storm. Self esteem, after all, is partly based on one’s ability to see oneself as in control.

As in mathematics and science, critical thinking is a valuable tool for assessing what we experience in the world. It helps us to parse what we read, what we’re told, what we think… It brings perspective to the unexpected, the hostile and the just plain annoying. It can and should be taught from grade school onwards, building on the simpler examples from year to year –class to class. Younger children may not understand the complexities of the Scientific Method, nor what Popper was on about, but with patience and persistence they will.

They deserve the chance…
