Ubi Dubium… | The Three Faces of Skepticism

Rather than go into a single definition of what modern skepticism is, already done in great detail on this blog’s Media Guide to Skepticism page by Sharon Hill, I’d like to discuss those aspects, those three faces, that to my understanding make it up.
What are those faces of skepticism? They are:
  1. Skepticism is a set of values, both intellectual and ethical: Skepticism favors intellectual honesty, sincerity, integrity, and a high value on the truth of whatever matter we look into. It is to have little patience with those who deceive, save those ‘honest liars,’ professional conjurors who are forthright about the inherently deceptive nature of their trade. Those who knowingly defraud, harm, or manipulate others are fair game for skeptical scrutiny and critiquing. Skepticism acknowledges and respects the limits of human perception, understanding and reasoning. It tells us about and arms us against our biases. It tells us that “I don’t know,” is a better answer to a question than an answer that is not only demonstrably false, but isn’t even worthy of being wrong. If a skeptic is in error, or is knowingly dishonest, they can be and ought to be be corrected, or exposed, by others who are not. Whatever their personal inclinations, if they are not honest, other skeptics will be, and they will be found out.
  2. Skepticism is a set of methods, a way of evaluating arguments and evidence to determine the likely factual status of claims. These are the methods of science, empiricism, and rational inquiry. Skepticism lets us know when someone’s trying to put us on, or putting others on, and that’s the first step to exposing them. Skepticism lets us distinguish sound claims from unsound and good argument from bad. It lets us know, when we are careful, when our prejudices are being pandered to, giving us the first line of defense against fraud and chicanery. These methods assume scientific literacy, scientific thinking, and an understanding of how we deceive ourselves and others through biases and motivated reasoning.
  3. The values and methods of skepticism assume a particular approach to reality. It assumes that there are such things as facts and truth. It assumes the world is knowable and that it is possible to tell truth from falsehood. It assumes that the world is real, regardless of the nature of that reality, it exists, and that it must for anything at all to be meaningfully true, false, or even possible. It assumes that the methods of science, empiricism, and rational inquiry are valid, useful, and powerful ways of knowing reality. It assumes in its methods that solid, reliable and effective ways of knowing are preferable to those that not only lead to error, but are neither self-correcting nor concerned with the actual truth of a matter. While it doesn’t necessarily assume philosophical naturalism, it does assume naturalistic methods, and so eschews resorting to unobservable or unfalsifiable ‘explanations’ for phenomena. But it has no trouble investigating anything that is knowably real and open to objective inquiry.
These are the three faces and together they form the core of my understanding of skepticism as an endeavor, whatever the state of organized skepticism at any time.

Criteria of Adequacy

People often harbor the misconception that science is just an archive, a library, a stagnant body of facts, or a belief system — a collection of truths, a particular worldview, an ideology, and not the vibrantly active, contentious, competitive, and continually advancing search for knowledge it is, with the ability it gives us as a species to enhance our understanding of the world and ourselves.MB3D33REG

Science isn’t the way it is today because some patriarchal Europeans during the Renaissance made some sh*t up and arbitrarily decided that that’s the way it will be for all time — It’s the way it is today, rather more different from how it was then, because that’s what’s been shown over time to work, what gets the best results right now.

Science is an almost Darwinian entity, and so evolves over time, those methodologies and philosophical underpinnings that work are adopted and retained, and the ones that turn out not to are just ditched. Science isn’t perfect, and it probably never will be, but it is progressive. And it’s the only human endeavor that’s designed from the bottom-up to be internally self-correcting.

Despite the occasional fraud or fabrication, the truth prevails. While individual scientists are no more paragons of moral virtue than the rest of us, science as a whole is self-policing. Because scientists like to try to dismantle each others’ theories, if one scientist isn’t honest, others will be. Propose a phony theory of astrophysics, and it will be exposed by a rival. In almost every instance, fraud or error in science are uncovered and vigorously called out by scientists themselves.

Any useful theory in science can have one or several, but often many more supporting ideas, each serving the purpose of a predictor, more properly, a hypothesis, and you need observational facts as well as logic to round a theory out, since it’s a bad idea to try to theorize on an empty mind, but even this just isn’t enough: you have to be able to go a wee bit further than what factoids you know.

To be of any worth, a theory should meet at least two or more conditions called Criteria of Adequacy — specifically a set of five that for purposes of this post will be known as Testability, Fruitfulness, Scope, Simplicity, and Conservatism. We’ll deal with them each in turn…


…One great way to tell genuine scientific theories from pseudoscientific ones is by whether or not they can be tested, and any functional hypotheses within a theory must have this property in order to be worth anything — if it doesn’t, well, it just doesn’t measure up as science.

Karl Popper’s idea that any scientific theory had to be testable to be valid was mostly sound, though there was a problem with his use of the word falsifiability for it is that strict, conclusive falsifiability or verification, final proof nay or yea, aren’t possible in science. This is because there is no way to be certain that new data won’t turn up in the future that could refute a hypothesis, and you can always rescue any hypothesis in spite of evidence by toying around here and there with the theory it belongs to. That, and the fact that almost any new theory is already seemingly refuted by a lot of the data available at the time it is first conceived.

Hypotheses can’t be tested all by their lonesome, only with others that make up the basic theory they are part of. Thus, even ‘reductionistic’ hypothesis-testing is holistic in the truest possible sense, since it is done in bundles of hypotheses…

Scientifically functional hypotheses should go further than the predictions that they make with the theory that they’re meant to support, and a hypothesis that doesn’t is what’s known as an ad hoc hypothesis, ad hoc, because my evil self is gonna go all Latin on you, means (in)this case only, and a grunchload of ad hoc hypotheses in a theory is a really good indicator that it is pseudoscience.

Hypotheses let us predict things by telling us what we should observe under what set of conditions, in order to provisionally confirm or confute them. Ad hoc hypotheses, on the other hand, don’t improve upon our understanding by telling us anything we don’t already know. A given hypothesis is of no scientific value if it cannot be tested against that most heinous of taskmasters, reality. If a hypothesis makes predictions on what we can and should observe that its own base theory doesn’t, or can’t, then it’s testable.

Let’s look at a sample hypothesis, the pixie hypothesis of home computer networks, which states that when one boots up the network, tiny pixies living in the the computer, DSL modem, and router flit around at near-light speeds inside the machinery and carry signals between the different circuits to make the computer work, and fly around at light-speed outside the machinery to carry Wi-Fi signals to all the laptops in the network.

As mentioned earlier, there can be any number of hypotheses in a theory, such as the blue LED pixie hypothesis, the green LED pixie hypothesis, the LCD screen pixie hypothesis, and so on, but the pixie hypothesis’ usefulness for scientific purposes depends on what it tells us about pixies, what it predicts we should observe.

Referring back to the base theory and trying to prove or disprove the existence of the pixies by booting up the network does us no good, for this is a tautology — circular reasoning — and the very thing that the pixie hypothesis is meant to explain. It’s obvious that we have to go beyond the basic theory.

Now if this hypothesis tells us that the pixies are visible or tangible or audible, we can just look inside the casing of the computer and network hardware to see or feel or listen around for signs of the pixies. If the hypothesis tells us the they are normally intangible and invisible and silent, but can be seen and touched or heard when the computer’s custom-built suped-up liquid coolant system is in overdrive, we can crank up the coolant system to make them visible. This hypothesis just doesn’t do us any good, though, and is not testable if it says that the pixies are always invisible, intangible, and produce no sound, not even the chattering of little pixie teeth induced by the chill of the supercooled computer.

Yes, I know — that was silly. It’s a general rule that to qualify as scientifically interesting — and valid — any hypothesis must observably predict more than what the theory it belongs to does, assuming that all other properties of the hypothesis are the same in worth.

But testability isn’t the only important factor, since we impart more worth to some hypotheses than others. We need to take more than just testability into account, and the next criterion to be considered is…


…which is a valid condition of a still worthwhile hypothesis and may suffice to rescue it even in the face of contrary evidence, since it lets said hypothesis successfully predict new observational data and to create, often without any initial foresight, entirely unexpected lines of research. If a hypothesis predicts more new and unexpected findings than others, all other factors being roughly the same in importance, then it is the best.

Oddly enough, this is true even if a hypothesis is tested and found to be false. Even in such a case, an incorrect but both interesting and useful, and therefore fruitful hypothesis can sometimes serendipitously lead to new discoveries, because of a number of factors, such as the researcher’s imagination, observational skill, and ability to take advantage of opportunities thrown their way by the winds of random happenstance.

But there are also fields of study that qualify as degenerating research programs, involving theories and hypotheses that are most obviously not fruitful, highly unproductive where pioneering research is concerned, that even if they aren’t limited severely in the phenomena they study, they predict not all that much in the way of new findings, and are largely unsuccessful in their predictions at best. And no, post hoc rationalizations and shoehorned postdictions don’t count.

Parapsychology is a good example of one such field, as it has never succeeded in predicting and actually revealing any new and unexpected observations, no practical applications for either ESP or PK, and no new facts excepting ingeniously contrived excuses as to why even its most cutting-edge research protocols don’t independently replicate when non-believers in psi are involved in the experiment.

Even to this day, after over 130 years of research, it is riddled with ad hoc hypotheses, such as the decline effect, the observer effect, psi-missing, and even bizarre claims of the retroactive skepticism of readers of parapsychology journals reaching back through time to affect (previously) successful experiments in the past.

In fact, despite largely unsuccessful attempts to co-opt quantum mechanics and other poorly-understood ideas of bleeding-edge physics for the purpose, such as zero-point energy fields and string theory, parapsychology still lacks a sound consensus on any coherent theoretical underpinnings.

Most of the claims of parapsychology violate much of what we can honestly say is currently known in biology, physics and psychology, three fields that it would have revolutionized had it been as successful as some of it’s advocates sometimes claim, and as successful as its pioneers would have wished it to become, given the time it’s had.

This is not to say that Psi violates laws of nature in any absolute sense, but it does appear to violate those laws as we presently understand them. Our understanding of these laws may indeed be incorrect, or incomplete, but unless parapsychologists can identify the ones that are, and demonstrate new laws with observational data that explain the universe better than the current ones, we have no good cause to suspect that currently known laws are wrong.


This is a crucial component of any theory with wide applications, how capable it is of organizing and putting our understanding of that which it describes all in the same convenient package, and this also has the bennies of reducing the probability of the theory being wrong. The superior theory is that which predicts and explains the widest range of phenomena, all other factors being the same in importance.

In my Gods of Terra science fiction setting, the discovery of Kurtz-Dunar Hypermatrix Theory (or KDHT for short) finally unified the older theoretical paradigms of Quantum Mechanics and Einsteinian Relativity into a fully integrated, coherent whole, incorporating more precise and deeper understanding of the first four forces they dealt with — Gravity, Electromagnetism, the Strong and Weak forces, and in addition, the Cosmological Constant, or Dark energy — and all of the various phenomena they governed, in addition to resolving any conflicts that had arisen in its predecessor theories.

KDHT was a distant descendant of String Theory, but one that had arisen when the technology of the day was up to the task of testing its predictions, which finally allowed humanity, and any similarly developed technological species, access to the Superforce and its technological applications, using it to more precisely manipulate its component forces and phenomena under their purview. It also had, in addition to the virtues of Testability, Fruitfulness and Scope, that of…


…which deals with a theory’s elegance and logical consistency. Generally, assuming everything else being about the same, the theory with the greatest logical coherence and the fewest unnecessary assumptions is the better.

Going back to our last example, Raoul Kurtz and Ranan Dunar’s highly successful Hypermatrix Theory was especially liked by its co-founders because of its parsimony and elegance, since not only was their idea tested and provisionally verified shortly after its conception, not only did it lead to new and surprising avenues of research, not only did it allow humanity relatively easy access to interstellar travel, cheap surface-to-orbit transit and biologically friendly long-duration space voyages through its tremendous applicability to a wide range of phenomena, its simplicity allowed for fewer possible ways to falsify it, thus making it more likely to be true when first formulated.

Simplicity allowed this “theory of almost everything” to stand apart from its more cumbersome competitors, and this criterion has been justly esteemed in the real world since the days of the Ionian Awakening in classical Greece, starting historically with Thales of Miletus.

You’ve likely kind of noticed how hypotheses explain what they do by postulating the existence of certain things, and simplicity tells us that it’s a good idea to resort to the use of the rule of thumb called Occam’s razor, which states that ‘Entities should not be multiplied without necessity.’

It’s important to consider the fact that assuming the existence of something without a really good reason is not a logical thing to do.

But even the revolutionary impact of Hypermatrix Theory, new as it was, also had to abide by one more criterion, the final one in this post, that of…


…which deals with a character of sound scientific hypotheses concerned with the consistency of new ideas with prior knowledge.

This is an important feature for what we can honestly say we know, and a ginormous red flag should pop up in one’s head about any sort of claims that conflict with much of what we have good reason to think we know, especially if what we know at present results in the creation of technologies and techniques that actually work, like the computer server that hosts this blog.

Unthinking acceptance of inconsistent ideas both erodes and forces us to reject what we know without sound reason. The plausibility of ideas that violate Conservatism is probably not very high if they go against applications of established knowledge that have real practical benefits.

Overall, a more conservative hypothesis is more plausible, more useful, and most closely fits previous valid claims to what we know, provided other criteria are of equal standing.

Even though KDHT led to a new and more powerful understanding of the universe, allowing mankind to tap the Superforce and spread across interstellar space, the properties of the Superforce, while some where specific to it, did not contravene those properties of its sub-forces, nor violate the new, deeper understanding of the older Quantum and Relativity theories, for example: Superforce radiation does not exceed the speed of light, traveling at roughly 300,000 Kilometers per second in a vacuum, falls off in strength over distances in accordance with the inverse-square law, and when sublimating into any of its component forces, obeys all of their physical properties, and finally, obeys Einstein’s law of E=mc² and all of the laws of Thermodynamics. It does not allow one to violate physical laws that still enjoy empirical support in the science of the Gods of Terra setting, rather allowing one instead to make use of those not previously known or otherwise poorly understood at best.

However, not all hypotheses are of equal worth, and it’s rational to accept an idea that doesn’t abide by one criterion as long as it abides by others.

Much to my Troythuluness’s regret, there is no such thing as a completely ironclad way to tell when any criterion should be outranked by others, and there is no formal methodology for applying them. There is no known way precisely measure the various elements of a hypothesis and no known means by which a formal ranking system may be applied to any of them.

We just might, for example, conclude that Conservatism should have a greater rank than, say, Fruitfulness, if the idea under consideration has a relatively narrow scope. Or Conservatism may be outranked by Simplicity and Scope, in particular if said hypothesis has a great deal of the latter, though Testability is a must.

Hypothesis selection is not a strict, mechanistic process involving rigid logic, and like any process of decision-making, like the proceedings of a court of law, much less the court of science, requires the exercise of our ability for sound judgment employing methods themselves not very amenable to formal conventions, though this process isn’t completely subjective either: There are processes that we can’t easily gauge that are nonetheless objective.

For example, it is not possible to strictly delineate the exact cut-off point at which light becomes dark, or at which the wavelength and frequency of red light becomes that of orange light, though it would be absurd to claim that these things cannot be distinguished from each other, with the difference between the extreme ends of these spectra, these wavelengths of light, or light and dark, being as objective as far as it goes.

Since most distinctions range along a continuum instead of there being a strict split between them, with a fuzzy but real difference, it would not be rational to argue that that because there is no arbitrary demarcation between light and dark, that the difference between them does not exist and that therefore they are the same. To suppose this is highly specious reasoning, the commission of the False Continuum fallacy.

It is also wrong to believe, for example, that spontaneous generation, alchemy, phrenology, vitalism, or luminiferous ether theory are still valid scientific ideas even if they were at one point. And I know of no diplomatic way to say this: To steadfastly adhere to a claim of fact, belief system or doctrine that isn’t supported by any of the criteria discussed in this post is to hold irrational views.

MetaCognitions | Thoughts on my Editorial Policy


I prefer rationalism to atheism. The question of God and other objects-of-faith are outside reason and play no part in rationalism, thus you don’t have to waste your time in either attacking or defending.

(Photo credit: Wikipedia)

The above quote, by the late Science Fiction writer and skeptic, Isaac Asimov, encapsulates nicely the essence of the current editorial policy.

I’m by circumstance, not by choice, a nonbeliever in all of the world’s ancient, respected, and confident faith traditions.

Let others believe as they will, whatever they will, as they will. I’ve no say in that.

I can have no say in that.

Skepticism, science, and rationalism, not atheism or anti-theism, are the foci of this blog.

My current editorial policy requires me to avoid posting on matters of faith or politics, unless their advocates try to make scientific claims, attempt to impede scientific literacy for ideological reasons, or indoctrinate the young or vulnerable for less than ethical intentions. ‘Nobody likes a skeptic’ it’s said, but scammers can be dangerous, and can part you from more than just your money. Those, not religion or politics themselves, are fair game.

No one wants to hear about how much I don’t believe this doctrine, or arguments against that theology, as those are matters outside of science and so outside the purview of this site.

No one wants to see yet another tiresome attack from me on faith, another boring tirade on contradictions in somebody’s holy book. No one cares, and neither do I enough to have blogged about it recently or do so anymore. I’ve said it all before, so no longer.

Earlier posts on my earlier views will stay up, as Google gets very angry about my deleting posts, and as I am not in the habit of writing inflammatory polemics there’s no worry there.

I admit, it’s a policy that I should have adopted long ago. So no rhetorical sparring with apologists, or debating political ideologues. This is not a forum for that…

…but for science, skepticism, and those things that matter to me…

…and the fractals. That’s all.

The Pure Majesty of Reality

Mission: Earth, Voyage to the Home Planet

Mission: Earth, Voyage to the Home Planet (Photo credit: Wikipedia)

Life, the universe, and yes, everything, has an astounding majesty readily apparent to the perceptive and tough-minded observer, this majesty being more apparent still to the scientifically literate.

Well, my toughness of mind is often not what I would wish, and my observational skills frequently lacking, but the contributions I bring to the table, with what little science-literacy I have, give me a picture of the world that in spite of its tragedies transfixes me in an awe bordering on terror, and sometimes almost brings tears to my eyes, as when noting the interplay of physical forces in my surroundings when walking on the beach or when looking at the stars at night through a telescope.

The things I see, hidden from mundane sight, yet seen with the mind’s eye through science, bring to mind the phrase much loved of some believers, “none are so blind as he who will not see,” but ironically this cuts both ways, and a good rejoinder to this would be “and none are so blinkered as he who sees what is not truly there to be seen.”

But the things I see with the mind’s eye are even better than the imaginary things seen through wishful thinking, for the things of science are real, and knowably so, for these things, as impossible as they are for mere human senses to make out — atoms; microbes; the molecule of heredity, DNA; the neurotransmitters being exchanged across the synapses of my brain as I type this; black holes; dark matter; dark energy; as familiar but invisible as gravity itself; the vast 100 billion galaxy universe beyond the range of the naked eye — these things are all tied to us in more profound ways than those promised by mystical doctrines.

We are unavoidably part of a reality we can only dimly know in a limited fashion, but the more we learn the more apparent our deep connection to the universe is, to paraphrase Neil deGrasse Tyson, “…to each other, biologically; to the Earth, chemically; to the rest of the universe, atomically.”

The real account of our origins, from the formation of the solar system, that of the Earth, the origin of life, and the evolution of that life once formed, leading to life as we know it today, is far grander, taking billions of years and colored by both variety in speciation and extinction on an epic scale, than in any ancient writings.

I look at the universe in times when my thinking is clearest, my mind’s eye most active, and my understanding surer, and I wonder why some have a need for anything beyond reality itself, a drive to add something to the universe that doesn’t need to be added, a supernatural component of reality beyond what we can possibly know.

Why? It’s an exercise in frustration sometimes, noticing people who see so little of what’s really there and wanting to replace what they don’t even know is there with ancient narratives of mystical forces and beings…

…things that have been related endlessly in the popular culture, since the times immemorial when they were and still are told around campfires.

Things wholly of human fancy and fiction as far as can be demonstrated.

Nothing wrong with stories mind you — I love good fantasy fiction — but in terms of claims of a separate realm of reality, it all seems too much alike to me, a failure of the human imagination with the same tired concepts circulated endlessly by a credulous media to a public all too eager for more of the same.

Even seeing what little I do, I’ve no need to add anything to reality that doesn’t need to be added — new discoveries will come as we make them, real knowledge with the added bonus of real understanding, not appeals to faith, arguments from ignorance and gods-of-the-gaps.

A View of Earth from Saturn

With the good science crowded out by bad science, even antiscience, too many miss out on seeing things as they are and replace it with the ignorant ravings of mystics in hoary texts that have been edited, reedited and edited yet more over thousands of years by political opportunists seeking to control and retain control over their followers.

But the people this happens to aren’t stupid. There’s a lot of native intelligence on humans, and I get the impression that most such people have been had by those in charge of whatever tradition they’ve been raised to accept, victims of those themselves victimized by indoctrination, punctuated by the occasional cynically knowing profiteer — pseudoscience and religion are lucrative businesses in much of the world — who knows perfectly well what he’s doing, and doesn’t care.

But all the bad in the world just means more good to be done, and even if winning is impossible, so what? I want to assist people in thinking for themselves, using their own considerable brainpower to reach more sound conclusions and make better decisions, and even if I can reach only one person in my life, then my time has been well-spent in achieving something meaningful and lasting.

I think that that one person can make a difference, and that alone makes it worthwhile.
