30 Misleading Terms Used in Science Literature

Let us look at some "give you the wrong idea" words and phrases used by scientists and science writers, terms that tend to mislead the general public. 

#1 Building Blocks of Life

Scientific literature is constantly misusing and abusing the phrase "building blocks of life." The very term is an improper one, because living things are internally dynamic to the highest degree, with a constant replacement of tiny parts (protein molecules and cells) occurring within an organism; so a comparison to a structure with static "building block" parts is inappropriate. If anyone refers to "building blocks of life," there are only two appropriate ways to use the term: (1) when referring to macroscopic life, the "building blocks of life" would be cells; (2) when referring to microscopic one-celled life, the "building blocks of life" would be protein molecules. But routinely science literature will refer to some low-level chemicals such as amino acids or nucleotides as being "building blocks of life" when they are no such things (being at best mere building blocks of the building blocks of life).  A particularly egregious abuse of language occurs when science literature mentions some organic chemicals that are not necessary for life and are neither the building blocks of life nor the building blocks of the building blocks of life, and such literature refers to such chemicals as "building blocks of life." Such misstatements occur often in astrobiology literature and origin of life literature. 

 #2 Long-term Potentiation

What is misleadingly called “long-term potentiation” or LTP is a not-very-long-lasting effect by which certain types of high-frequency stimulation (such as stimulation by electrodes) produces an increase in synaptic strength.  The problem is that so-called long-term potentiation is actually a very short-term phenomenon. A 2013 paper states that so-called long-term potentiation is really very short-lived:

"LTP always decays and usually does so rapidly. Its rate of decay is measured in hours or days (for review, see Abraham 2003). Even with extended 'training,' a decay to baseline levels is observed within days to a week."

So-called long-term potentiation is no more long-term than a suntan. The use of the term "long-term potentiation" for such an effect is deceptive, particularly when it is suggested that so-called "long-term potentiation" might have something to do with explaining memories that can last for 50 years or longer. 

#3 Synaptic Plasticity

When I do a Google search for "plasticity definition," the first result I get gives me a definition of "the quality of being easily shaped or modified."  The Merriam-Webster online dictionary gives two definitions of "plasticity":

1. The quality or state of being plastic especially: capacity for being molded or altered.
2. The ability to retain a shape attained by pressure deformation.

It is rather clear what the intention was when scientists first started using the term "synaptic plasticity."  The intention was to bring to mind the idea of synapses being like clay in which memories can be written. Used by the Babylonians who used cuneiform, writing in clay was one of the oldest methods used by humans to record information. Clay had two great advantages: (1) a person using a metal stylus could instantly write letters on clay; (2) clay could permanently store letters written on it. 

There are two reasons why it is very misleading to be using the term "synaptic plasticity." The first is that no one has ever observed any effect in which synapses quickly take on some particular shape or pattern in response to some causal factor. Nothing like any molding or shaping effect has ever been observed. 

The second reason is that term "plasticity" implies the retention of some pattern that was produced by a shaping or molding effect. The second Merriam-Webster definition of plasticity is "the ability to retain a shape attained by pressure deformation."  What we observe in dendritic spines and synapses is such a high level of variability and instability that there is every reason to doubt that they could be capable of retaining any pattern if such a pattern were ever to be impressed on them. 

The effect that is misleading called "synaptic plasticity" should instead be merely called "synaptic variability" or "synaptic instability."

#4 Dark Matter

Scientists speculate that most of the matter in the universe is some invisible form of matter not yet discovered. They call this "dark matter." But that is a misleading term which implies visible matter that is dark. The "dark matter" imagined by cosmologists is invisible.  A non-misleading term cosmologists should be using for such a possibility is "invisible matter."

#5 Dark Energy

Scientists speculate that most of the energy in the universe is some invisible form of energy not yet discovered. They call this "dark energy." But that is a misleading term which implies visible energy that is dark. The "dark energy" imagined by cosmologists is invisible, and cosmologists should be calling it "invisible energy."

#6 Earth-like Planets

Many Earth-sized planets have been discovered, but no Earth-like planets has been discovered outside of our solar system. We should not be calling a planet "Earth-like" unless life was discovered, and life has not been discovered on any other planet. Scientists and science journalists very often describe a merely Earth-sized planet as an "Earth-like planet." Such language is very misleading. 

#7 Adaptations

Biologists use the word "adaptations" to refer to what they believe are extremely complex accidental inventions. For example, a biologist may refer to the first eyes as "adaptations," or the first wings as "adaptations," or the appearance of hands with fingers as an "adaptation." 

What is misleading here is the use of a euphemism designed to hide us from the shockingly far-fetched belief that is being advanced. Imagine if a biologist were to say something like this (referring to the Cambrian Explosion): "At this point in natural history there occurred in many different species the appearances of the extremely complex accidental inventions called eyes." Alarm bells would go off in a person's mind, for he may remember that he has never witnessed in his life anything like an extremely complex accidental invention, and the idea has a nonsensical sound to it. 

By using the term "adaptations," biologists avoid this problem.  But it is misleading to refer to very complex biological innovations as "adaptations," since the word "adaptation" (derived from the word "adapt") merely means "a change or the process of change by which an organism or species becomes better suited to its environment" (to give a dictionary's definition).  It is misleading because the term suggests some little not-too-hard thing has occurred, when some incredibly-hard-to-credibly-explain thing has occurred. In a biology paper whose primary author is Tom Roschinger, a CalTech scientist in the Division of Biology and Biological Engineering, we read, "Biological systems have evolved to amazingly complex states, yet we do not understand in general how evolution operates to generate increasing genetic and functional complexity." Biological innovations so complex and organized that there is no current credible explanation for them should not be referred to by some term ("adaptations") that make them sound like some small-change affair. 

#8 "Reservoirs" in Reference to Extremely Sparse Molecule Levels, which May be Referred to Inaccurately as "Large Organic Molecules"

In the post here I discuss an example of an outrageous abuse of language sometimes occurring in science literature: the use of the term "reservoirs" to refer to molecule levels that are vastly more sparse (i.e. vastly less dense) than the molecule levels found in earthly clouds. The molecules referred are sometimes sometimes some of the simplest organic molecules, but are misleadingly referred to as "large organic molecules." 

#9 Astrobiologist

Until extraterrestrial life is discovered, the term "astrobiologist" must be classified as a misleading term, as it suggests or implies that extraterrestrial life has been discovered.  It would be less misleading if people referred to astrobiologists as "extraterrestrial life theorists," which would correctly signify the speculative nature of their studies. 

#10 String Theory

The term "string theory" is a term that misleads us by suggesting theorists speculating about something not-very-unusual (string being a very common household item). But string theorists make some of the most bizarre speculations ever made. It would be better to call string theorists "other-dimension theorists," which would tell us about how speculative such theorists are.  Different versions of string theory postulate up to 26 different dimensions. 

speculative scientific theory


#11 Many Worlds Theory

Groundlessly claiming a warrant in quantum mechanics, Hugh Everett created a groundless pure-craziness theory that the universe is constantly splitting into different copies of itself, so that every possibility becomes reality. The term "Many Worlds" theory is used for Everett's theory. But such a term is very misleading, because it makes an insane idea have a reasonable sound to it. Because so many extrasolar planets have been discovered, it sounds reasonable for someone to say that there are many worlds.  But Everett's theory involves infinitely more than the mere claim that there are many worlds, since it involves the madness of claiming that there are infinite versions of each and every world, and infinite different versions of you and everyone else. 

#12 Body Plan

The term "body plan" is a profoundly misleading term that biologists love to use, a term that opens the door to deceptions about DNA. In biology literature the term "body plan" has a very limited meaning, something vastly different from a complete plan for constructing an organism. According to a scientific paper "a body plan is a suite of characters shared by a group of phylogenetically related animals at some point during their development." The wikipedia.org article on "body plan" tells us this: "A body plan, Bauplan (German plural Baupläne), or ground plan is a set of morphological features common to many members of a phylum of animals." 

According to this definition, all chordates (including men, bears, dogs and fish) have the same body plan. So when biologists talk about "the human body plan" they
are merely referring to the common characteristics of all chordates, including men, bears, dogs and fish:  basically just the existence of a backbone and bilateral symmetry (having the same things on both sides of the body).  They are not referring to the structure of the 200 types of cells in the human body, or the structure of internal organs, and are not referring to the dynamic intricacies of human physiology. But anyone hearing the term "body plan" will think the term referred to a complete specification of a human body.  So, most misleadingly, biologists may say that this or that "determines the body plan," when all they mean is the beginning of a bilateral organism with a backbone, something a thousand times simpler than the final product of the internally dynamic and enormously organized human body.  This is as misleading as someone saying that he has built a starship, when he has merely built a boat in the shape of a star. 

#13 Scientific Consensus

The term "scientific consensus" is one of the abused terms in the world of scientific academia. Some leading dictionaries define a consensus as an agreed opinion among a group of people. The first definition of "consensus" by the Merriam-Webster dictionary is "general agreement: unanimity." But scientists have very often referred to a "scientific consensus" on some particular topic when there was no good evidence that such a consensus existed, and quite a bit of evidence that no consensus actually exists.  

Some scientist advancing a new theory will start to say "more and more" scientists are accepting his theory. Once he starts to get a few people adopting his ideas, he may claim that "there is a growing trend" towards accepting his theory.  If some small fraction of scientists adopts his theory, he may claim this as a "growing consensus." Then if maybe half of scientists adopt his theory, he may claim this as a "consensus."  It is easy to see why such misleading statements occur. The more popular you make a theory sound, the more people will be likely to adopt it. 

I may note that claims of either a scientific consensus or anything remotely approaching a scientific consensus tend to be extremely unreliable.  The only way to reliably measure how many scientists believe in a theory is to do a secret ballot of scientists. Such secret ballots (of large numbers of scientists) never occur or almost never occur. 

#14 Talk of Brain Regions "Lighting Up" or "Activating"

All regions in the brain are constantly active. When scientists do scans of brains, they typically find differences in activity of less than half of one percent (about 1 part in 200) between one region and another. But science writers often refer to such very slight differences in activity as cases of some particular brain region "lighting up"  or some particular brain region "activating." That is misleading, as it suggests a large difference in activity, when the actual difference in activity is only very tiny. 

#15 Skull (When Used to Describe Bone Fragments)

The word "skull" is a word with a very exact definition. The Merriam Webster dictionary defines a skull as "the skeleton of the head of a vertebrate forming a bony or cartilaginous case that encloses and protects the brain and chief sense organs and supports the jaws."  Paleontologists and their press workers routinely misuse the word "skull," by using the term to refer to small bone fragments believed to be from a skull. Calling such fragments a skull is often as misleading as using the term "automobile" to refer to a bumper, a seat and a tire collected from a junk yard.

#16 Big Bang

The phrase "Big Bang" when used in reference to the origin of the universe misleads us by suggesting the idea of the universe started out as some big bomb that exploded, a kind of "cosmic egg" that blew up.  The Big Bang theory actually holds that the universe began in a state of infinite density called a singularity, and expanded very rapidly from such a state, with the density rapidly dropping.  A non-misleading term to describe the theory might be to call it the "origination-from-zero-radius theory" or the "origination-from-infinite density" theory. 

#17 Chemical Imbalances

It has long been claimed that one or more psychiatric problems are caused by "chemical imbalances." Scientists do not have any understanding of how some "chemical balance" results in normal mental function, and they do not have any understanding of how some "chemical imbalance" could cause psychiatric problems. 

#18 Genetically Determined

Scientists and science writers very often claim that some outcome is "genetically determined" when there is merely evidence that the outcome is genetically influenced.  There is a huge difference between a first thing merely influencing or affecting a second thing (merely having some effect on it), and the first thing determining the second thing (being the main cause of that thing).  For example, the weather influences how a car looks, but the weather does not determine how a car looks (a car's look is determined by the manufacturing process used to create it).  We do not have any evidence that either human mental traits or the structure of the human body is genetically determined. Because genes merely specify low-level chemicals such as protein molecules, we have the strongest reason for thinking that human mental traits and the physical structure of humans cannot be determined by genes. All that we have is evidence for a much weaker claim: the claim that human mental traits and the physical structure of humans is influenced or affected by genes. 

#19 Scientific Method

The myth that scientists follow some algorithm called "the scientific method" is one of the most long-standing myths of scientist culture. Statements of how this "scientific method" works vary widely but a typical description will include steps such as this:

  1. Formulate a hypothesis
  2. Design an experiment to test the hypothesis
  3. Communicate results whether the experiment supports the hypothesis
  4. If the experiment fails to support the hypothesis, formulate a new hypothesis.
Scientists do their work in a hundred different ways, and most do not follow such a method. Descriptions of the so-called "scientific method" make it look like scientists are ready to discard a hypothesis when it fails to be supported by an experiment.  The reality is that belief traditions arise in scientific communities, and scientists tend to very stubbornly cling to such belief traditions, regardless of observational or experimental results.  When scientists get a result that conflicts with their belief traditions (which may include some theory), scientists typically handle this in ways that do not involve abandoning the theory they are testing.  Such ways may include:
  • Creatively interpreting the negative result to make it look like something supporting the hypothesis being tested.
  • Changing the hypothesis to match whatever result was obtained.
  • Playing around with the data in some statistical way until the negative result can be claimed as a positive result in favor of the hypothesis (or a neutral result consistent with the hypothesis).
  • Dismissing the result conflicting with the hypothesis by special pleading, such as claiming that far-above-chance results in tests of psi or ESP were produced by subjects cheating, or claiming that there was experimenter error or equipment error.  
  • Simply filing away the results without trying to publish them, and retrying the experiment, perhaps with some modification that will make the experiment much more likely to produce a seemingly positive result. 

#20 "The Neural Circuitry Behind" Some Behavior or Mental State

The very term "neural circuit" is misleading. A circuit is an unbroken electrical path, typically a roughly circular path that starts and ends in the same place. Neural pathways are not circular or even rather circular, they do not start and end in the same place, and they have a huge number of breaks, the breaks of synaptic gaps. Therefore, sections of brain tissue should not be referred to as "neural circuits."

As for the the idea that some behavior or mental state or mental trait can be explained by some arrangement of tissue in the brain, such an idea has no empirical support. 

#21 Claims Brains Are "Wired for" or "Hard-Wired for" This or That

The term "hard wiring" is an old mechanical term meaning to be determined by a particular arrangement of wires. Before modern electronics and software programming, the behavior of certain mechanical devices such as switchboards were determined by arrangements of wires, particular arrangements being called types of "hard wiring." Although neuroscientists sometimes speak as if investigating arrangements of wire-like components in the brain might shed light on human behavior, no one has ever shown that any human behavior can be explained by some arrangement of such components in the brain. It is therefore very misleading to claim that humans are "hard-wired" to do any particular thing. 

#22 Theory of Everything

The misleading term "theory of everything" has long been used by physicists to mean some theory that would unite two major physics theories: quantum mechanics and the theory of relativity.  The term has always been misleading, because each so-called "theory of everything" is merely a physics theory, and explains nothing in the world of biology or psychology. 

#23 "Regulate" or "Control" or "Sculpt" or "Mold" or "Direct" When Used About Genes or Chemicals

Chemicals inside the body are mindless things, and it is misleading to refer to them using action words that suggest they are intelligent agents. The quote below in a biologist's essay suggests that there is a massive problem of biologists using verbs in an inappropriate way when describing genes:

In scientific, as well as popular descriptions today, genes 'act,' 'behave,' 'direct,' 'control,' 'design,' 'influence,' have 'effects,' are “responsible for,' are 'selfish,' and so on, as if minds of their own with designs and intentions. But at the same time, a counter-narrative is building, not from the media but from inside science itself."

#24 "Intended to Simulate" When Used About Experiments Like the Miller-Urey Experiment

For seventy years science literature has been speaking in a very misleading way about experiments like the Miller-Urey experiment. That experiment used a small closed glass aparatus filled with chemicals. Every other day the chemicals were continuously bombarded with electrical discharges. The result was some amino acids that accumulated at the bottom of the apparatus. Claimed as a simulation of early Earth conditions, the apparatus was no such thing, as nowhere in the early Earth did there ever exist such an enclosed space subject to even a thousandth as much electrical energy. Moreover, the chemicals used are now believed to be a mixture not matching the atmosphere of the early Earth. 

The results of such an experiment never should have been claimed as a result in support of claims of abiogenesis. But for 70 years science literature has been passing off such an experiment as something supporting claims that amino acids could have naturally formed  on the early Earth.  Typically science writers will not claim that the experiment realistically simulated the early Earth (a claim that is obviously false). Instead, we will merely hear that the experiment "intended to simulate" or "was designed to simulate" the early Earth. The insinuation is that the experiment might have simulated the early Earth, but we know that the experiment never was a realistic simulation of the early Earth.  The same phrase of "intended to simulate" is used for other experiments that just as obviously fail to realistically simulate early Earth conditions.  

#25 Cambrian Diversification

Since the time of Darwin, the Cambrian Explosion has always been the greatest embarrassment to Darwinists.  The main branches of animal species are called phyla, and there are about 35 phyla in the animal kingdom. Contrary to what we would expect under the assumptions of Darwinism, all or almost all of the animal phyla first appear in the fossil record in a relatively short span of time, what is called the Cambrian Explosion occurring about 640 million years ago.  Under Darwinist assumptions, we would expect such phyla to have originated gradually during the past 700 million years. 

To reduce this embarrassment, some science writers have started using the euphemistic term "Cambrian Diversification," which does not sound like such a dramatic and sudden burst of biological innovation.  You can compare this to someone avoiding references to the "atomic bombing" of Hiroshima and Nagasaki, and referring instead to the August 1945 events as the Hiroshima and Nagasaki "urban renewal projects," or someone trying to trivialize the painting of the Sistine Chapel's ceiling by referring to it as a "ceiling color diversification."   

#26 Natural Selection 

Selection is a term meaning a choice by a conscious agent. The so-called "natural selection" imagined by those who use such a term does not actually involve any selection or choice.  The "natural selection" imagined by biologists merely involves a survival-of-the-fittest effect, in which fitter organisms survive longer or reproduce more. The duplicity of using the term "natural selection" for some imagined effect that is not actually selection is a word trick that was started by Charles Darwin, who coined the term "natural selection."

#27 Selection Pressure

When biologists use the term "selection pressure," they are simply using a variant of the term "natural selection." The term "selection pressure" is doubly-misleading, first because there is no actual selection involved in so-called selection pressure (selection being an act by a conscious agent), and second because there is no actual pressure involved.  

#28 Early Human

The defining characteristic of humans is their use of symbols.  The term "early human" is very often misleadingly used in science literature, to refer to pre-human species which have never been proven to have used symbols. Such language is used to try to bolster claims that species arising before humans were ancestors of humans.  A person who lacks any good evidence that Species X existing before humans evolved into humans may simply take the shortcut of calling this Species X an "early human" species.  But if there is no good evidence that Species X used symbols, then it should not be called an "early human" species. 

#29 "Genetic Blueprint" or "Genetic Program" or "Genetic Recipe"

What I call the Great DNA Myth is the myth that inside DNA is some blueprint or recipe that specifies how to make a human body.  

There are various ways in which this false idea is stated, all equally false:

  • Someone may describe DNA or the genome as a blueprint for an organism.
  • Someone may describe DNA or the genome as a recipe for making an organism.
  • Someone may describe DNA or the genome as a program for building an organism.
  • Someone may claim that DNA or genomes specify the anatomy of an organism. 
  • Someone may claim that genotypes (the DNA in organisms) specify phenotypes (the observable characteristics of an organism).
  • Someone may claim that genotypes (the DNA in organisms) "map"  phenotypes (the observable characteristics of an organism) or "map to" phenotypes.
  • Someone may claim that DNA contains "all the instructions needed to make an organism."
  • Someone may claim that there is a "genetic architecture" for an organism's body or some fraction of that body. 
  • Using a little equation, someone may claim that a "genotype plus the environment equals the phenotype," a formulation as false  as the preceding statements, since we know of nothing in the environment that would cause phenotypes to arise from genotypes that do not specify such phenotypes. 

All of these versions are equally false, because DNA only contains low-level chemical information (such as which sequences of amino acids make up polypeptide chains that are the starting points of protein molecules), not high-level structural information Many biology authorities have confessed this reality, and at the post here you can read statements by more than twenty biology experts stating that DNA is not a blueprint or a program or a recipe for building an organism. 

#30 "Essential for"

In the world of neuroscience we often have incorrect claims that this or that protein or this or that brain part is "essential for" some cognitive ability.  In some cases experiments have shown that the cognitive ability continues to exist even when the supposedly "essential" thing has been removed.
