The process of science--the systematic, evidence-based, rigorous, controlled exploration of the processes of the natural world--has produced an explosion of knowledge and understanding. Since the Italian Renaissance and the Abbasid period in the Persian empire, both of which saw enormous gains in scientific thinking and with them huge leaps in technology and understanding, science has been the beacon of light shining in the darkness of superstition and ignorance.
So it's probably not too surprising that many folks who seek to embrace all sorts of non-scientific ideas try to claim that their ideas are science. Calling these ideas "science" gives them a stamp of validation. If an idea is scientific, that means it has greater legitimacy in many people's minds.
And the world needs to cut that shit out. Not all ideas are science, yet everything from phrenology to metaphysics to "crystal energy" tries to clamber onto the scientific bandwagon.
Most recently, the cry of the pseudoscientist has become "Quantum mechanics says!" Folks who can't actually define what quantum mechanics is are nevertheless eager to fill New Age bookstores with books that claim to "prove" that quantum mechanics validates their ideas.
So here's a handy-dandy, more-than-pocket-sized guide that will help you tell what science actually is and is not. Ready? Here we go!
RULE 1: If it doesn't make a precisely defined, testable, falsifiable claim, it is not science.
This is the first and most basic premise of this whole "science" business. If someone claims "Science shows us that" or "Quantum mechanics proves that" and the next thing out of their mouth isn't a testable, falsifiable claim, then what they're saying is probably bollocks.
For example, "Science says that energy in any form always exhibits relativistic mass, and mass-energy equivalence is a function of the speed of light in the form of E=mC2" is a testable hypothesis. It makes a specific statement about mass-energy equivalence which can be measured and either verified or falsified.
On the other hand, "Quantum mechanics says that consciousness is the most fundamental part of the universe" is not a testable hypothesis. There is no definition of "consciousness" or what it means to be "most fundamental." It makes no empirically verifiable claim. It might be perfectly reasonable as a statement of philosophy, or metaphysics, or religion, and there might be value in debating it as a a matter of religious doctrine or philosophy, but it is not science.
RULE 2: Just because a scientist says it doesn't necessarily mean that it is science.
Scientists are people. Science is one particular way of looking at the physical world, but people--even scientists--often look at the world in many ways. A person who is a scientist can also hold ideas that are not scientific ideas.
For example, the famous physicist Max Planck was a scientist who helped to revolutionize our understanding of physics by laying the foundation for quantum mechanics.
He was also a Christian theologian who wrote several works of theology, and upon retiring from active research became a church warden in Germany.
Planck said that energy could only be emitted from a blackbody radiator in quantized form, and that the energy thus radiated was the product of the frequency of the radiation multiplied by a universal constant h, which is now known as Planck's constant. This is a precisely defined, testable, falsifiable statement; it is science.
He also said "All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind," and that this mind was the mind of an omniscient, benevolent god. This statement does not make a testable, falsifiable claim; it is not science. Folks who use this statement to argue that Max Planck "proved" that the idea of universal consciousness is part of physics do not understand what physics is.
(Interestingly, Planck's religious views led him, late in life, to reject the statistical models of quantum mechanics, because he could not accept a universe whose laws at a small scale were based on probability and not determinism.)
RULE 2a: Competence in one area of science does not necessarily mean competence in another area of scienceRULE 3: If it can't be reproduced by other people, it isn't science
There is often a tendency to assume that scientists must be smart, and that if they know something about one field, that means they must be just as smart in other fields too. This can become particularly insidious in fields which seem, from the outside, to be related or similar.
For example, one of the early discoverers of the human immunodeficiency virus was virologist Dr. Luc Montagnier, a French researcher who, together with Jean-Claude Chermann and clinician Willy Rozenbaum, helped isolate and identify the retrovirus that causes AIDS.
Later, Dr. Montagnier would say that AIDS can be treated with diet alone, and that drugs are unnecessary to halt its progression.
To an outside observer, the fact that Dr. Montagnier is a Nobel-prizewinning virologist seems to give this notion credibility. However, being a virologist is not the same thing as being an immunologist. It is possible to understand a great deal about the molecular workings of viruses without actually having a good understanding of the molecular biology of immunology.
The manner in which HIV thwarts immune response is extremely complex and quite subtle. The fact that Dr. Montagnier is a virologist does not mean that his statements on immunology are necessarily credible. Accepting his pronouncements about the treatment of AIDS simply because he is a virologist, without evidence, violates Rule 4 below and is not science.
One of the central tenets of science is the notion of reproducibility--the idea that what is true for Bob is also true for Sue, and that if something is a property of the physical world, it can be observed to be true regardless of who's doing the observing.
In science, there are no wizards for whom nature behaves differently than it does for everyone else. If a person in New York City observes that the gravitational force between two mass-bearing objects is the product of a universal constant times the product of the masses of the objects divided by the square of the distance between them, and conducts an experiment which shows the universal constant to be 6.67384x10-11N(m/kg)2, then an experimenter in Teheran should, if he sets up an experiment to determine the gravitational constant, arrive at the same result...at least within the error margin of his experiment and procedure. Science does not depend on personal philosophy, political ideology, religion, subjective experience, or philosophical views. Anything which does vary by religion or politics or philosophy or subjective experience is not science, and should not be labeled as "science."
RULE 3a: If a statement makes a claim that some part of the physical world which has been measured and tested should be different from what it has observed to be, that statement is probably not scienceMore generally, a result which only one person can arrive at, but which others can not reach when they try to perform the experiment themselves, is probably an error. Any idea which proposes that something is true only for a particular guru, or for people who have completed the eighth level of illumination under the supervision of an enlightened master, is not science.
If I were to propose a new model of gravity, and my model of gravity predicts that the universal gravitational constant is 42 N(m/kg)2, then something is very wrong, because many repeated experiments done by different people under different conditions with different methodologies have all agreed that this is not, in fact, what the universal gravitational constant is.
Of course, any measurement of the physical world is going to have error bars associated with it. No measurement can ever be absolutely perfect. And sometimes it may be that some new model might predict some physical property to be something different from what it is believed to be, but close enough that the error bars in its measurement mask the difference.
It is also often true that simple models, such as Newton's laws of motion, can be observed to be true under one set of conditions, but reality deviates from the models under different conditions. Newton's laws don't work well when, for example, things are moving close to the speed of light.
None of this means that observations can just be discarded whenever a new idea comes along. Any theory that accounts for the motion of objects moving at the speed of light had better also agree with Newton's laws for objects moving slowly with respect to one another, because we've measured the behavior of objects moving slowly with respect to each other, aNewton's predictions work. If someone says that a baseball won't follow Newton's laws when it comes off a batter's bat, that person's statements are probably not science, or at the very least will fail when tested.
And speaking of error...
RULE 4: Scientific claims are only as valid as the evidence which supports them
Albert Einstein famously observed, "No amount of experimentation can ever prove me right; a single experiment can prove me wrong." Any scientific idea, no matter who supports it, is only as good as the empirical evidence that backs it up.
No scientific idea is "proven right" by the evidence. Rather, the evidence may support the idea, but the only real proof is evidence which contradicts the idea's predictions. An idea which has a lot of evidence confirming it can usually be trusted...but even a single disconfirmation is all it takes to knock it down.
For that reason, one thing which often quickly separates science from things that aren't science is that in science, we tend to look for evidence that might prove an idea wrong. When an idea is being tested, it is scrutinized from all angles with the question, "What predictions does this idea make, and how might we construct an experiment to show that prediction is false?" The more vigorously an idea resists disproof--the more experiments are done to try to prove it wrong, and instead reveal results that fit the idea--the more the idea can be trusted.
People who want the validation of science for their ideas often complain that the scientific community ignores or ridicules them. From that point, such people often imagine a "conspiracy" of scientific orthodoxy, in which scientists collude to silence them.
That isn't how it works. Instead, science says of new ideas, "Okay, where's the proof? If you want us to listen to you, show us the proof. If your idea can't be disproven, it isn't science. If you don't have reproducible evidence to show us, go away."
For many years, the reigning idea about stomach ulcers was that they were caused by stress. Ulcers were treated with extremely expensive drugs that inhibited production of stomach acid. These drugs had to be taken continually, and would not cure the ulcers; as soon as acid production went back to normal, the ulcers returned.
In 1982, Dr. Barry Marshall and Dr. Robin Warren announced that they believed stomach ulcers were actually caused by infection with an exotic form of bacteria with the ability to protect itself from the harsh acid in the stomach, and that cheap antibiotics could completely cure them.
The scientific community ignored them.
Until they provided evidence, by showing that swallowing the bacterium Helicobacter pylori would give stomach ulcers to a person who didn't have them, and a course of antibiotics would cure them.
At that point, the scientific community changed its mind, the idea was accepted, and Dr. Marshall and Dr. Warren won the Nobel Prize.
Claims like "Scientists just don't want to recognize my idea because it's too revolutionary" or "Medical doctors won't accept my idea because it would mean less money for drug companies" are not science.
RULE 4a: Extraordinary claims require extraordinary proofRULE 5: A vaguely-worded, rewritten, or imprecise restatement of a scientific principle is not (necessarily) science
Every so often, someone proposes an idea that would turn the whole, or a good part of, our understanding of the physical world on its head. Whenever that happens, the person who proposes the idea had better have a whole lot of evidence if he is to be taken seriously.
If someone claims that the sun came up this morning, we don't need a lot of proof to think that claim is likely true. It fits with the observations we've made and with our understanding of what happens in the morning. It's predicted by our models of cosmology and the behavior of the solar system.
On the other hand, if someone claims that archaeology supports the notion that the Bible is literal truth, or that ancient space aliens built the Pyramids, those claims require quite a tremendous weight of evidence if they are to be credible.
And not ordinary evidence. The notion that some events described in the Bible might be supported by archaeology is not overwhelming; we know the city of Troy existed, but that's not proof that the Iliad is literal truth. We know that the Danish king Harald won many battlefield victories, but that is not proof that the Viking god Odin favored him.
When it comes to supporting extraordinary claims, simple garden-variety evidence just doesn't cut it. A picture in a Mayan temple of a guy with a round circle around his head doesn't rise to the level of proof required that aliens visited the Mayans, especially in light of the fact that that notion is actually less plausible, with its prerequisite assumptions of interstellar space travel and the unanswered issue about why space aliens would hang around with pre-technological societies for a time and then just go away, than the idea that they had strange tastes in hats. The idea that the Pyramids could be built by hand is actually less farfetched than the idea that space aliens somehow traveled here in violation of current understanding of the laws of physics to do it and then leave.
That doesn't mean we understand physics or that interstellar travel is impossible. It just means that given two explanations for something, one of which is "people are smart and good at engineering" and the other of which requires turning all of physics upside-down, the former is probably the safer bet. Statistically, extraordinary claims are extraordinarily unlikely to be true.
The notion of ancient space aliens has a certain pop-culture appeal, which makes it sound like a better story than "a bunch of people were clever, had nearly unlimited supplies of raw physical labor, and were good at engineering." However, it's still not science. Rule 9 talks more about that.
RULE 4b: The plural of 'anecdote' is not 'data'
Our brains are marvelous, finely-tuned, incredibly complex instruments carefully optimized to get it wrong.
For folks who live in small pre-industrial tribes in the African veldt, getting it wrong is often the right thing to do. People facing the possibility of hostile leopards or poisonous food need to be able to make snap decisions in an instant, and if the decisions are wrong, those people might not spread their genes. So our brains are gifted to us by our ancestors who made snap decisions conservatively, and lived.
If someone feels sick, and takes a pill that she thinks will make him better, and after taking the pill she feels better, it's often true that no force in the universe can convince her that it wasn't the pill that did it. If someone is told a story by a friend, or witnesses something himself, he will tend to place a great deal of emphasis on it, and tend not to look at things which might contradict that experience. All these helped our ancestors; they didn't necessarily know that it was the mushroom they ate which made them feel bad, but our ancestors who tried to repeat the experiment sometimes died for that curiosity.
Worse, we don't remember the world the way it is. When we remember something, that memory isn't like a video recording; it's pieced together based on our ideas, our preconceptions, our emotions at the time, and our emotions now. We remember things that fit our preconceptions and don't remember things that don't.
We also remember stories, especially stories that relate to our own inner narratives about our place in the world. Anecdotes, by their nature, are more powerful stories than, say, double-blind controlled studies, or mathematical charts, are.
All this adds up to the fact that our personal experience is rubbish when it comes to understanding the physical world. No matter how vivid your own experience might be, no matter how many examples of something being true you may personally remember, ideas based on your experience or on reports of other people's experiences are not science. When someone says that homeopathy totally cured his uncle's cancer or his uncle's broken arm, that is not science. When someone says "My toddler got a measles vaccination and six months later I found out she was autistic, that shows measles vaccinations cause autism," that is also not science.RULE 4b(i): Personal experience, revelation, and subjective data are not evidenceRULE 4c: A thought experiment is not a real experiment
No matter how powerful they are, personal experiences--even experiences (especially experiences) you can't understand, aren't actually proof that something exists. Any argument made on the basis of personal experiences is not science.
The brain is fabulously complex, and it can do some pretty weird things. People often have the personal experience of having some sort of revelation imparted to them from the outside, or of leaving their bodies, or of encountering strange and terrifying things.
All these things can be caused by physical processes in the brain. Strong G-forces, among other things, can reduce blood flow to the brain; reduced blood flow can create powerful experiences of floating outside or above one's body. It is possible to wake in the middle of a nightmare, and be conscious of where you are while still being unable to move or to speak; these "night terrors"can be incredibly powerful visceral experiences, but they are not proof that there are monsters at the foot of the bed. (Sadly, many folks throughout history, and sometimes even today, have become so convinced that these waking nightmares are proof of malevolent forces that they have accused their neighbors of witchcraft or sorcery, with disastrous results.)
Proponents of past-life regression often try to claim that the experiences of people under hypnosis are proof of reincarnation. These claims are not science. A person under hypnosis is easily suggestible, and hypnosis can often create vivid, compelling, detailed, rich, powerful memories of events that simply didn't happen. The inner subjective experience of the world is easily altered or tricked. Memories "recovered" under hypnosis, like any other subjective experiences, are not science.
The physical world doesn't always work in ways our intuition might predict. Thought experiments are sometimes useful as ways to consider an idea, but they are not actually evidence; the result of a thought experiment is never as compelling as the result of an actual experiment.
A classic example is the behavior of two falling weights. If we are to imagine how they act, we might think that a heavy weight--a 10-pound dumbbell, say--would fall faster than a lighter weight, like a 2-pound dumbbell. In fact, this seems so obvious that many philosophers didn't bother to test it.
When you do test it, however, you observe a counter-intuitive result: heavy weights fall at the same speed as lighter weights.
Any claim which attempts to use a thought experiment as the only evidence which supports it is not science.
One of the places where people often get tripped up in making all sorts of claims about science that aren't actually science is Heisenberg's uncertainty principle.
The common lay understanding of Heisenberg's uncertainty principle is that you can not know simultaneously both the precise position and the precise momentum of a subatomic particle. This is one of the cornerstones of our understanding of the physical world, and it lays the foundation for the probabilistic approach to particle physics.
It also lays the foundation for a lot of metaphysics and confusion. Christians argue that the uncertainty principle does not apply to God because God has infinite knowledge. Yogic teachers interpret Heisenberg's idea to mean that human awareness has a tangible effect on the universe, and therefore human intelligence supersedes the laws of physics. New Age philosophers have interpreted it to mean that all things in the world are one with human consciousness.
All of these statements are not science. In addition to not making falsifiable claims (Rule 1), they misunderstand what Heisenberg's uncertainty principle is. The uncertainty principle itself is given by
where ¦Òx and ¦Òp are the standard deviations of position and momentum and ? is Planck's constant divided by 2¦Ð.
There are no terms for "consciousness" or "awareness" in this equation. Heisenberg's principle doesn't state that we can't know a particle's position and momentum at the same time because human consciousness affects the particle or because human awareness is inferior to God's awareness. We can't know a particle's position and momentum at the same time because the particle does not HAVE defined position and momentum at the same time. Subatomic particles are not like little marbles and they don't act like little marbles.
More generally, Rule 6 applies to any imprecise statement of any scientific principle. The misunderstanding that evolution says mankind came from apes, and arguments based on it, are not science; evolutionary biology says no such thing, but instead asserts that humans and apes share a common ancestor at some point in the past. The misunderstanding of mass-energy equivalence that leads some mystics to claim that matter is an illusion and everything in the universe is actually made up of "energy fields" is not science.
RULE 5a: A metaphor used to express a scientific statement is not itself scienceRULE 6: If you start by assuming the premise that you're trying to prove, then the result is not science
The pursuit of science often produces results that are not easy to understand without a thorough, rigorous educational background. Because of this, scientists and science teachers will often use metaphors to try to communicate the gist of scientific principles.
These metaphors themselves are not science and should not be confused with science. Any metaphor, if pushed too hard, will break. A metaphor by itself isn't a scientific truth, and on the flip side of the same coin, finding a flaw in a metaphor that's being used to explain a scientific idea is not the same thing as finding a flaw in the scientific idea.
One metaphor that folks often tend to get tangled up about is the metaphor of Schr?dinger's cat. This metaphor is used to help explain a very complex and non-intuitive concept called "quantum entanglement," in which a system of subatomic particles may exist in more than one state simultaneously, and then undergo "collapse" and behave like it is in a single state when it encounters something whose state depends on its state.
Schr?dinger proposed a system where a cat might be in a superposition of states where it is simultaneously both alive and dead until it interacts with an observer. However, this thought experiment is only a metaphor. It is not possible to place a cat (or any other large, macroscopic object) in a superposition of states in this fashion. In point of fact, another place where laypeople trying to understand quantum mechanics get tangled up is in the idea of an "observer." In Schr?dinger's thought experiment, the detector that responds to radioactive decay by either killing or not killing the cat is an observer! An observer isn't a person looking at something. It's anything whose state depends in a thermodynamically irreversible way on the state of the thing being observed.
An argument such as "Schr?dinger's cat proves that we all create the universe around us" is not science--not just because it fails to make a falsifiable claim (Rule 1), but also because it confuses the metaphor with the underlying idea. The metaphor itself is also not science.
A common fallacy of reasoning is assuming a premise you're attempting to prove is true, then using the truth of that premise to "prove" the premise. This kind of reasoning occurs often in claims about the existence of a god or gods. A simplistic version looks like "Consciousness exists within the universe the universe. There can only be one source of consciousness. The source of consciousness must itself be conscious. Since there can only be one source of consciousness, and since that source must be conscious, and since the only consciousness which can create the universe is god, then god must exist."
Embedded within this argument are the assumptions that its premises ("there can only be one source of consciousness," "source of consciousness must itself be conscious") must be true. If it is possible for consciousness to arise from things which aren't conscious, or if consciousness is an emergent property which can arise in many places from many different types of events, then the argument doesn't work. The premises must be true for the argument to stand, but the premises are what the argument is trying to prove! The argument itself is therefore not science.
People make claims that are purported to be science but that assume their own premise often. Conspiracy buffs often try to argue that the World Trade Center collapse must have been the result of a controlled demolition because it looks like a controlled demolition and only controlled demolitions look like that--an argument that assumes one of its premises ("only controlled demolitions look like that") to be true. This claim is not science.
Now, this is different from assuming the premise in order to show an absurd result, which is an argument called reductio ad absurdum. The premise is shown to be false by deriving a false outcome which would have to be true if the argument is true. For example, let's say that a person claims to have found a perfect chess-playing strategy that would always let him win any game, with no possibility of a loss or a draw, regardless of which side he played. If we assume the claim is true, we quickly reach an absurd conclusion: two people playing against each other who both employed this strategy would both win, with neither losing nor drawing. But this is not possible in a game of chess; ergo, the claim to have discovered such a chess-playing strategy must be false.
Using reductio ad absurdum arguments--assuming a premise is true in order to show that this true must lead to a contradiction--is science. Assuming that a premise is true for the purpose of proving it is true, however, is not science.
RULE 7: If your idea depends on common sense or what is intuitively obvious, it is not science
I once had an old friend express great consternation to me when he heard that time moves slower inside a gravity field, so time on the surface of the earth moves slower than it does in space. How was it, he asked me, that gravity could slow down his wristwatch? Wasn't it possible to build a watch that wasn't affected by gravity? His intuition didn't cope well with the notion that it wasn't the watch that was moving slower...it was time. Everything--not just the watch, but all physical processes, chemical reactions, even nuclear reactions, move slower in a gravity field.
We don't think of time as being malleable in this way because our intuition was not shaped where it is something we observe directly. Yet it is true nonetheless, even though it messes with our intuition about time.
The physical world is not under any particular obligation to make intuitive sense to a human being. In fact, human intuition developed in a very specific environment--an environment of relatively large, relatively non-energetic things moving relatively slowly with respect to each other. Unless we believe that the entire universe is this way, there's no reason to believe that the entire universe will behave in a way that matches our intuition. And in fact it doesn't.
There are several schools of New Age thought that say the universe can be understood by intuition. Some people claim that intuition springs from an all-knowing, all-powerful subconscious mind, in harmony with the essential oneness of universal consciousness. In addition to being appeals to intuition, these ideas don't make falsifiable claims (Rule 1), and often depend on a vague, metaphorical understanding of quantum mechanics (Rule 5). They are not science. Claims based on these ideas, such as the notion that a psychic healer can intuit a sense of what is wrong with a patient merely by concentrating, are also not science. Appeals to "trust your intuition" about what is correct are likewise not science; our intuition is limited by our experiences, our environment, and the things that we want to be true or really wish were true.
RULE 7a: If your idea depends on notions of 'perfection,' or Scripture, or philosophical arguments, or what is beautiful, or what is aesthetically pleasing, it also isn't scienceRULE 8: Arguments like "They laughed at Galileo!" or "We don't know everything yet, so anything is possible!" are not science
The creation "science" folks have a really, really bad case of science envy. In their literature, they describe themselves as scientists; there's a creation science movie in which a person who's claimed to be a paleontologist claims that he and more mainstream scientists look at the same information, they simply start from different premises so they reach different conclusions.
Unfortunately, the moment you start from the premise that a particular idea, book, work of scripture, or philosophical construct must be true, what you're doing is not science.
Creation "science" tends to assume its own premise (Rule 6), but it also runs off the rails by assuming the infallability of one interpretation of one bit of scripture as well. When you've already arrived at a fixed conclusion ("The world is 6,000 years old") and you interpret evidence only in such a way as to validate that conclusion, what you're doing is not science.
Science must be able to change its conclusions based on the things that are being observed, rather than observing things with an eye toward making them fit the conclusion. This is very hard for human beings to do naturally; we tend to see that which validates our ideas and not see that which doesn't, a pernicious tendency of the brain that goes by the name "confirmation bias." One way to deal with this, as I mentioned in Rule 4, is to search for evidence that prove your ideas wrong, not search for evidence that proves the ideas right. The more firmly an idea resists attempts to knock it down, the stronger it is...at least until that bit of evidence comes along that does knock it down.
They also laughed at Bozo the Clown, and he is no scientist. Also, it was church leaders, not scientists, who rejected Galileo.
RULE 9: Storytelling is not science
We are a storytelling species. We tell ourselves stories every day to make sense of the world, often without even knowing we're doing it. When someone says something on the Internet that we don't like, we tell ourselves stories about that person's intentions, intelligence, or agenda in order to make whatever she said seem less valid. When we see things happen, we tell ourselves stories about why they happened in order to try to give ourselves a sense of what makes the world behave the way it does (and, often, in order to make ourselves feel like we have control over the world).
These stories are much more satisfying to us than answers like "I don't know." When ancient people looked at the sun and asked "What is that thing?" they invented stories about gods and heros and flaming chariots speeding through the sky. If two people were asked "What is the sun?" and one of them said "The sun is an orb created by a divine all-powerful being who ignited it and threw it into the sky" and the other said "I don't have the faintest idea," the person with the story about all-powerful beings was more likely to be believed, because his story is far more satisfying than "I don't know."
Even today, people tell stories in the face of "I don't know." A religious person might say to a scientist "If the universe came from a singularity that exploded during the Big Bang, then where did that singularity come from?" When the scientist says "I don't know," the religious person's story about gods or the wheel of creation and destruction or the all-beingness of an eternal deity feel more compelling. But they are not science. Just because someone has a story to fill in a hole where someone else says "I don't know" doesn't actually mean that the story is true, and certainly doesn't mean the story is science.
Conspiracy theories are a form of storytelling. We tend to like a good story; we find good stories engaging and memorable, especially when they describe ideas we can relate to. Stories of sinister government plots and secret machinations in the halls of power excite and grab us more than stories about angry religious fanatics who seize airplanes and fly them into buildings; 9/11 conspiracy theories gain traction just because they sound like more entertaining stories and they validate ideas we already have. These stories often assume their own premises (Rule 6), depend on anecdotal information (Rule 4), and/or rely on people speaking outside their areas of competence (Rule 2) as well, and are not science.
And while we're on the subject of conspiracy theories...
RULE 10: Starting from a conclusion and then working backward is not science
This is related to assuming the thing you want to be true, but it's not quite the same thing. If you start from a fundamental position ("Western medicine is all a scam by greedy corporations," "Space aliens are visiting us," "The government is using secret mind control agents on the public") and then work backward from that, attempting to find proof for the conclusion while ignoring contradictory information, then what you are doing in snot science.
Science starts from observation and forms conclusions based on those observations. The conclusions are not determined in advance; conclusions are reached only when evidence points to them, and if contradictory evidence comes along, those conclusions are discarded. Science looks at ALL the evidence, not only evidence that seems to support the conclusion. It also considers alternative explanations for the evidence.
If you start out by saying "I just know there are mind control drugs in the water--now I need to find the proof!" then what you're doing is not science.
