Science Educators Are Doing a Poor Job of Educating the Public

Based on my frequent reading of poor-quality literature written by science professors and science journalists, I had the strong suspicion that a large fraction of the general public have a poor understanding about basic facts of science and fundamental theories of science.  I tried to get some data confirming this suspicion, but this turned out to be very hard work, "like pulling teeth." It seems that our science educators are very bad about polling the general public to determine how well average people understand basic facts of science. I could not find a single paper or article involving a poll in which the general public was asked something like 100 multiple-choice questions to determine how well they understand basic facts of science. 

But after spending hours looking for information, I was able to find a few revealing indications of just how poor a job our science educators have done.  One was a Pew Research poll which asked people whether electrons are smaller than atoms. One of the most basic facts of physics you can learn is that atoms are composed of three types of particles: electrons, neutrons and protons.  If our science educators were doing a good job, we would expect that at least a majority of the public would answer "Yes" to the question "Are electrons smaller than atoms?"  But according to the Pew Research poll discussed here, only 47% of the US public think electrons are smaller than atoms. 

In the poll discussed here, over 700 people were asked questions testing their knowledge of the location of bodily organs. For each organ, they were shown four pictures, each depicting the organ in a very different part of the body.  Only 46% of the general public could correctly identify the location of the lungs; only 27% could correctly identify the location of the stomach; and only 40% could correctly identify the location of the ovaries. 

In the paper here ("A Study of Common Beliefs and Misconceptions in Physical Science") about 300 people were asked whether this statement was true:

"An astronaut is standing on the moon with a baseball in her/his hand. When the baseball is released, it will fall to the moon’s surface."

Only about one third of the people answering gave a correct answer identifying the statement as true. The statement tests whether someone understands the basic idea behind the law of gravitation, that all massive bodies exert a force of gravity. 

In some cases when the population is asked a rather basic science question, almost all of the people answering will give the same answer, an answer that is wrong. In the paper "Hints of a Fundamental Misconception in Cosmology" we read of a poll in which 167 college students were asked if they had heard of the Big Bang theory. Only 54% answered "yes." That 54% were then asked if the Big Bang theory described an "explosion from pre-existing matter" or an "explosion from nothing." 80% answered "explosion from pre-existing matter," only 1% answered "explosion from nothing," and 18% declined to answer.  The Big Bang theory does not describe any explosion from pre-existing matter. The theory describes the universe suddenly beginning in an expanding state, with its radius or diameter starting out as zero, something that is best described as "explosion from nothing" rather than "explosion from pre-existing matter." 

It is rather clear from these examples that science educators have done a very bad job of educating the public.  There are two main ways in which such educators have gigantically failed us.

Gigantic Failure #1: Indoctrinating the Public in False or Very Dubious Claims

One of the main ways in which a science educator can fail is by teaching doctrines that are dubious or untrue, selling such doubtful claims as "science." Sometimes such a failure is relatively harmless. For decades cosmologists and astronomers have endlessly taught the dubious speculative ideas of dark matter and dark energy. Neither have been directly observed, and neither has any place in the Standard Model of Physics.  Relatively little harm is done by such poor teaching. We are told that the universe consists mainly of invisible dark energy, and that most of the universe's matter is invisible dark matter. Such dogmas have very little to do with who we are or how we got here, so teaching such dogmas does little harm. 

An entirely different state of affairs involves the false or dubious dogmas taught by biologists and psychologists, dogmas that misinform about who we are, how each of our individual bodies and minds arose, and how humanity itself arose. These include the following very dubious or groundless dogmas endlessly repeated by our science educators:
  • The groundless legend that a biologist of the nineteenth century (Charles Darwin) created a theory that explains the origin of species such as the human species.
  • The groundless boast that biologists currently understand how there arose fantastically organized organisms such as birds, mammals and humans. 
  • The completely fictional claim that scientists have some understanding of how life could have originally started on our planet.
  • The untrue claim that DNA or its genes have some blueprint or program for making a human body, and that the progression from a speck-sized zygote to the state of vast organization that is an adult human body occurs because of the reading of such a blueprint or program. 
  • The unfounded claim that human minds can be explained as being products of the human brain.
  • The falsehood that there is little difference between humans and animals, and that humans are a type of animal (the latter claim being one that is "proven" solely by appealing to senseless and arbitrary classification conventions of biologists).
  • The unfounded claim that human memory processes such as memory formation, lifelong preservation of memories and instant memory recall can be explained by processes in the brain. 
By teaching these untrue or very dubious claims, our science educators have committed an enormous crime against the general public: the crime of filling people's minds with false or very dubious ideas about who they are, how their bodies and minds arose, and how their species arose. Such miseducation is not merely a failure, but a kind of intellectual crime of a very bad type. Teaching boastful claims that benefit the prestige of science educators like themselves at the severe cost of filling people's minds with the worst type of false or unfounded ideas, our science educators have been guilty of errors as bad as those committed by medieval educators who taught that sickness is caused by demon possession. 

Gigantic Failure #2: Failing to Properly Educate the Public About Many of the Most Important Realities of Bodies, Minds and Nature

Our biology educators have been extremely bad about educating the public about many of the most important realities regarding life, minds and matter.  Such a failure often seems to have a strategic nature. It is as if our biology educators are deliberately trying to teach "crayon sketch" depictions of living things, so that the public will be more likely to believe in ideas of accidental unguided origins. 

Consider the question of the origin of life. Biology educators are constantly using the very misleading phrase "building blocks of life." We constantly get a phony story that goes like this:

"Long ago there was a primordial soup that was rich in chemical building blocks of life. Then with the help of some lucky event such as lightning or heat, life got started."

The idea of simple "building blocks of life" is profoundly erroneous, for reasons discussed in the visual below. 
 
building blocks of life
Beside the deceit depicted in the visual above, there is a lot of additional deceit involving claims of building blocks of life. Science educators often claim without warrant that "building blocks of life" would have been abundant in the early Earth, a claim not supported by any experiments realistically simulating the early Earth. Science educators often make untrue claims such as "the building blocks of life are abundant in space." A look at the abundances of units such as amino acids in space will show that they exist in only the tiniest amounts such as 1 part per billion. 

Our science educators habitually make untrue claims suggesting progress in understanding a natural origin of life, something that has not at all occurred.  The reality of investigative failure is rarely described. 


Our science educators routinely present to us the most preposterous claims about the origin of life, such as claims that life can originate from non-life when some "spark of life" occurs from something like lightning. Our science educators can get away with such deceptions because they have committed the most appalling failure to properly educate people about the vast complexity and enormous organization of even the simplest living things. 

Our science educators routinely fail to properly educate the public about the complexity of cells. Such educators fool people into thinking that cells are thousands or millions of times simpler than they are, by using deceptive diagrams of cells, diagrams that make cells look very simple.  Human cells are so complex it is sometimes said they are as  complex as factories or cities. 
 

Continuing to teach the outdated and groundless legend that the origin of species was explained in the 19th century by Charles Darwin, our science educators fail to educate the public about the enormous hierarchical organization of the human body. That organization is listed in the table below. The items in yellow are facts that Darwin never knew about during his lifetime.


HUMANS CONSIST OF HUMAN BODIES AND HUMAN MINDS.

Human minds have displayed a vast number of capabilities, many of which mainstream scientists fail to properly study.

HUMAN BODIES MAINLY CONSIST OF ORGAN SYSTEMS AND A SKELETAL SYSTEM.

The human skeletal system contains 206 bones.

ORGAN SYSTEMS CONSIST OF ORGANS AND SUPPORTING STRUCTURES.

Examples of organ systems include the circulatory system (consisting of much more than just the heart), and the nervous system consisting of much more than just the brain.

ORGANS CONSIST OF TISSUES.


TISSUES CONSIST OF VERY COMPLEX AND VASTLY ORGANIZED  CELLS

There are more than 200 types of cells in the human body, each a different type of system of enormous organization. Cells are so complex they have been compared to factories with many types of manufacturing devices. 

CELLS TYPICALLY CONSIST OF VERY COMPLEX MEMBRANES AND THOUSANDS OR MILLIONS OF ORGANELLES.

  • A cell diagram will typically depict a cell as having only a few mitochondria, but cells typically have many thousands of mitochondria, as many as a million.

  • A cell diagram will typically depict a cell as having only a few lysosomes, but cells typically have hundreds of lysosomes.

  • A cell diagram will typically depict a cell as having only a few ribosomes, but a cell may have up to 10 million ribosomes.

  • A cell diagram will typically depict one or a few stacks of a Golgi apparatus, each with only a few cisternae. But a cell will typically have between 10 and 20 stacks, each having as many as 60 cisternae.

ORGANELLES CONSIST OF VERY MANY PROTEIN MOLECULES AND PROTEIN MOLECULE COMPLEXES.

There are some 100,000 different types of protein molecules in the human body, each a different type of complex invention. Protein molecule complexes are groups of different types of protein molecules that work together as team members to achieve a function that cannot be achieved by only one of the proteins in the complex. Very many protein complexes have so many parts working together dynamically that such complexes are now being called "molecular machines." 

PROTEIN MOLECULES CONSIST OF HUNDREDS OR THOUSANDS OF WELL-ARRANGED AMINO ACIDS, EXISTING IN A FOLDED THREE-DIMENSIONAL SHAPE.

Small changes in the sequences of amino acids in a protein are typically sufficient to ruin the usefulness of the protein molecule, preventing it from folding in the right way to achieve its function.  See "The Fragility of Fine-Tuned Protein Molecules" section of the post here for quotes stating this. 

AMINO ACIDS CONSIST OF ABOUT 10 ATOMS ARRANGED IN SOME SPECIFIC WAY.

Some amino acids have 20 atoms. Given 10+ atoms in amino acids, and an average of about 470 amino acids per human protein molecule, a human protein molecule contains an average of about 5000+ very well-arranged atoms. Amino acids in living things are almost all left-handed, although amino acids forming naturally will with 50% likelihood be right-handed.

ATOMS CONSIST OF MULTIPLE PROTONS, NEUTRONS AND ELECTRONS.

A carbon atom has 6 protons, 6 neutrons, and 6 electrons.

Why do our science educators fail to decently educate the public about all these different levels of organization? I suspect because it is such educators may sense that the more you know about the vast amount of complexity and organization in human bodies, the less likely you will be to accept the boast that science educators seem hell-bent on promulgating: the boast that scientists understand how the human species originated. Claims of the accidental origin of something are inversely proportional to the complexity and organization of that thing. The more organized and the more well-arranged something is, and the more well-arranged parts it has,  and the more fine-tuned the arrangement of its parts, the less credible is a claim that the thing arose by blind accidental processes.  For example, someone throwing a deck of cards into the air many times might produce one or two times a "house of cards" consisting of one card leaning diagonally against the other. But if the whole universe was filled with people throwing decks of cards into the air, doing that half of their lives, it would be vastly improbable that even one of them would ever accidentally produce a triangular house of cards consisting of thirty very well-arranged cards.  

We are now in a situation where it is very clear that the wonders of biology are far greater in their hierarchical organization and fine-tuned dynamic complexity than anything that humans have ever constructed. An aircraft carrier is a less impressive work of fine-tuned organization than the human body. Humans know how to make aircraft carriers equipped with all of their aircraft. There is not a corporation in the world or a nation in the world that could construct from lifeless materials a living adult human body. It is notable that humans are completely incapable of creating machines that can reproduce themselves.  There is not a robot in the world capable of building from raw materials a robot just like itself. But self-reproduction is something that occurs throughout the world of biology, as does molecular machinery

What we see in biological organism are massive numbers of engineering effects and endless examples of information-rich fine-tuned architecture. Such a reality makes nineteenth century explanations of biology origins sound like old wives' tales. Ink splashes don't produce long functional essays telling how to perform complex tasks; accidents don't engineer things; and random variations don't create novel astonishing works of information-rich fine-tuned architecture. It is not true that we can explain such wonders of biology by a simple principle of "random variations occur, and nature saves the good stuff," because most of the good stuff we see  requires arrangements of atoms so improbable you would never get such good stuff from random variations.  The reason that would never happen is pretty much the same as the reason why ink splashes don't produce well-written essays telling how to do complex things. 

But our science educators keep senselessly claiming that the wonders of biology are not the product of intelligent agency, but mere accidents of nature, as accidental as mountains. They keep telling us that we must follow opinions of the scientist Darwin, reached around the year 1859.  To keep such a legend afloat, our science educators fail over and over again to teach about the reality of the enormous engineering effects in our bodies. As a substitute, they offer the crudest "crayon sketches" of our bodies and our minds. 

Below from page 137 of a PhD thesis is a list of biological systems described as if they were very impressive machinery:

An article by scientists discusses molecular machines in the human body:

"A molecular machine (or ‘nanomachine’) is a mechanical device that is measured in nanometers (millionths of a millimeter, or units of 10-9 meter; on the scale of a single molecule) and converts chemical, electrical or optical energy to controlled mechanical work [1,2]. The human body can be viewed as a complex ensemble of nanomachines [3,4]. These tiny machines are responsible for the directed transport of macromolecules, membranes or chromosomes within the cytoplasm. They play a critical role in virtually every biological process (e.g., muscle contraction, cell division, intracellular transport, ATP production and genomic transcription)...Myosin, kinesin and their relatives are linear motors that convert the energy of ATP hydrolysis into mechanical work."

We do not learn about such impressive realities from the vast majority of our science educators.  Instead of teaching about such sophisticated realities, such educators have endlessly repeated childish "old wives tales" about how a human body originates. The main such tale has been the lie that a human body arises from a reading of a blueprint in human DNA, a blueprint of how to make a body. No such blueprint exists in our DNA, which does not even tell how to make any of the cells in our body.  And if such a blueprint existed, it would not explain how we get our bodies, because blueprints don't build things. 

Our science educators should have very humbly confessed the truth, saying: "We don't understand how humanity originated; we don't understand how any human mind originates; we don't understand how any adult human body originates; and we don't even understand how human cells are able to reproduce."  But instead, having crowned themselves as Grand Lords of Explanation, our science educators kept telling whatever lies they needed to tell to get people to believe their achievement boasts. 


A large part of the failure of science educators has been the failure to teach the public about many important observations having the greatest relevance to the nature of the human mind: observations of spooky events that humans can't explain and anomalous human mental powers that scientists can't explain. Senselessly our science educators declared such observations to be taboo, largely because they help undermine the dogmas that such educators try to promote, such as the dogma that the mind is merely the product of the brain.

When teaching about the brain, our science educators routinely fail to tell us about some of the most important facts we could learn, such as the very heavy signal noise all over the place in the brain, the unreliable transmission of signals across chemical synapses, the lack of any microscopic discovery of learned knowledge in human brains, the lack of any understanding of a neural system by which memories could be encoded, the lack of any thing in a brain that could explain instant memory recall, and so forth. We were not told about such things because our science educators wanted us to believe a dogma that they cherished, that minds are merely the products of brains. 

Some of the main science educators are science journalists, who these days are notorious for their production of misleading clickbait stories with frequently phony headlines. 


bad science journalism

Nowadays science journalism is a kind of "anything goes" hall of mirrors in which the chief object seems to be to attract clicks on interesting-sounding headlines that lead to pages containing ads, pages that generate revenues for various parties. 

science news problem

In the area of physics and cosmology, our science educators had the most meaningful and interesting account that they could have told: an account of a universe mysteriously appearing out of nothing, in an incredibly fine-tuned state, equipped with very many fine-tuned fundamental constants and fine-tuned laws necessary for the existence of creatures such as humans.  But our science educators failed to tell that story properly. Instead of learning of such an account in high school, which would have kept students interested, our high school physics students were tortured by boring calculation problems.  

Our science educators taught us a naive, authoritarian model of science, a kind of triumphal "scientists keep gloriously marching towards the truth" story. This was not a correct description of the "a loop of two steps forward, and one step backward" reality of science: the reality that scientists are conformist members of belief communities that often promote outdated dogmas that are balls-and-chains inhibiting the progress of science, and that groupthink and herd behavior frequently chains scientists to bad old ideas that keep being taught way past their proper expiration date. Our science educators constantly advanced a profoundly erroneous "they can explain all the big stuff" portrait of scientists at odds with the reality that human knowledge is merely fragmentary, and that what humans know is very tiny compared to what they don't know. 

scientist misinformation

When it comes to science education, the public has been very badly misled. The public put its trust in science educators, entrusting them with the enormous responsibility of acting as guides to help understand who we are and what kind of universe we live in.  Very many or most of our science educators have badly betrayed that trust.
