“I have high cholesterol,” my mother sighed over the phone. “Just got back from my doctor, and my cholesterol reading was 523.”

“Is that high?” I asked. I knew nothing about cholesterol to say nothing of medicine’s ability to measure it. But I know my mother. If the doctor found something alarming, she would immediately go about and make any necessary changes to correct the problem. She wasn’t disciplined in all aspects of her life, but when it came to her health, she was. Fear is a powerful motivator.

She proceeded to tell me everything she knew about high cholesterol, which is what the doctor told her. Cholesterol and fat are responsible for heart disease and strokes. It’s caused by eating fatty food and food high in dietary cholesterol like eggs. And with heart disease in the family and the leading cause of death among Americans, my mother immediately changed her diet. If she left any eggs in the refrigerator, they were for making cookies and cakes. Butter from cows milk fat- out. Whole milk- gone. Cheese, cottage cheese, and yogurt- to the back!

My mother was no longer eating eggs or whole milk or butter or most other dairy products. Unfortunately, that didn’t do much for her cholesterol levels. “Still too high,” she’d tell me. I could tell she was worried. Anxious even. Lurking in the back of her mind was her father, who died of a massive heart attack at the young age of 72. Playing a game of pool with his friends, he leaned against the pool table, crumpled to the ground, and died. Maybe her fate was sealed.

For her, worry came naturally. It was 1995. She was in her mid 60’s, in great shape, and a breast cancer survivor. With dozens of grandchildren, my mother had a lot to live for.

Eventually, I, too, have my cholesterol levels checked. To my consternation, my triglycerides are a bit whacked. My grandfather dies young of a heart attack, and my mother has high cholesterol. It only stands to reason that I, too, would be afflicted. Today, we know that individual cholesterol levels are largely a function of one’s genetics.

My mother is eventually prescribed a statin drug, and her high cholesterol count did come down a bit- but just a bit. I asked her if there were any side effects in taking these drugs. Sure, but that didn’t make her any less of a believer. She committed herself to an egg-free low-fat diet, taking her statin meds, and going for a brisk walk every morning.

During one of my many visits, I would open her kitchen cabinets in search of a bowl of cereal. I found one unopened and one half-eaten box of Special K next to the refrigerator. ‘Heart Check’ they claimed. The Kellogg folks had some research done, and a ‘Heart Check’ symbol from the American Heart Association was printed on the corner of the box. Kelloggs paid the association thousands of dollars for the right to claim it ‘heart healthy.’ A bowl of Special K would reduce my mother’s cholesterol, the box implied. I’m sure she thought that to be true. Then on to the refrigerator for some milk. All I could find was ‘skim’ milk fortified with vitamin D. I hated skim milk in part because it tasted as if it had been watered down. That wasn’t the case the milk industry assured me. Removing all the fat from milk also changed its color. At least the margarine folks attempted to make their product have the look and texture of butter. With no other options, I grabbed a bowl of some Special K and skimmed milk and choked it down. I would never eat it again. I’d rather a bowl of water and soggy cardboard.

Being healthy and young, I could afford to be cavalier about what I ate. I recall a great sense of optimism about what appeared to me was incredible advances in health science. With increasing rapidity, magazine and newspaper articles touted each discovery. If taken at face value, one had the sense that eventually, heart disease and a host of other conditions would soon be eradicated- and in my lifetime. Science was finally going to discover the fountain of youth. I had nothing to fear because science was all over it. It would have been easy to believe that science was on the brink of knowing everything they needed to prevent death itself. Perhaps a pill with no known side-effects.

Good health sells. Glossy magazines touting all sorts of good health content piled up on my mother’s kitchen table. She’d read these magazines and soon became a bit of an expert. At least she thought she was. An article would claim this, and soon she believed that. My mother read a book by Dr. Ancel Keys titled ‘Eat Well and Stay Well.’ Dr. Keys would claim the reason for writing the book was to declare war on cholesterol. Then he was featured on the cover of ‘Time’ magazine as the foremost authority on why atherosclerosis (heart disease) was killing so many. My mother believed all of this. She grew up in an age when you could believe what you read.

The sun was shining brightly one winter, Florida morning. My wife and I were visiting her grandfather, who was well into his 80’s. His wife had faithfully made him a breakfast of half a grapefruit, one hard-boiled egg, and a strip of bacon every morning for years. After breakfast, he’d chow down on a crossword puzzle to keep the synapses firing. I recall inquiring about his breakfast habits and his cholesterol level. If he knew and told me, I don’t recall. But it didn’t stop him from enjoying his regulation breakfast every morning. He lived to be 92 years old.

The human biological system is incredibly complex made more so because each individual is a unique system unto its own. My mother is much different than my wife’s grandfather. We each contain an infinite number of physiological variations. Throw in all the possible environmental differences such as obesity and exercise and the quality of healthcare, and we begin to understand how difficult research on human nutrition must be. Then consider how long some effects of our human diet can take to affect our health either positively or negatively. Many years in many cases.

To understand how so many nutritional scientists bought into the notion that a diet that contained fat and cholesterol would certainly lead to death by heart disease, we need to examine the nature of early research. But equally important, we best understand what the rest of the world did with this information. I hope to shed some light on how we deviled the egg with shoddy science, sophisticated public relations, and the shameless use of fear and intimidation. The images of arteries clogged by fatty deposits and cholesterol traumatized a generation, including my mother.

The ‘Deviling’ of the Egg

In the early 1900s, science was making significant strides in understanding human systems. Heart disease had been around a long time. Since we’re curious enough to poke around a corpse for clues, researchers in Germany found something interesting. The observations soon turned into a theory by esteemed German pathologist Rudolph Virchow when he posed that cholesterol in your blood became the ‘plaque’ in your veins.

Taking a different tack, the Russians were studying rabbits. Having fed rabbits food high in cholesterol, Nikolaj Nikolajewitsch Anitschkow from St. Petersburg, discovered that the rabbits soon suffered from arterial lesions. Clear and convincing evidence that cholesterol leads to plaque buildup in the arteries. Eventually, someone took a closer look at this bit of research and suggested a possible flaw. Rabbits are herbivores and don’t naturally eat things with cholesterol. Feeding rabbits high doses of something they never eat is like feeding us rotting contaminated food to examine why worms appear immune to salmonella. The same experiment was then conducted using the common dog. Dogs are carnivores with a diet more similar to humans. When fed a diet high in cholesterol, dogs did not develop arterial lesions as the rabbits did.

In 1953, Dr. Ancel Keys published the Seven Countries Studies. He collated data from seven countries whose population was known for their high consumption of dietary fats and a high incidence of heart disease and connected the two. Why he didn’t include data from all 22 countries in which data was collected is still not known. Some have speculated that it did not support his hypothesis. He had a book to sell. Only later, when data from all 22 countries were eventually tallied, little to no correlation was found between the consumption of dietary fat and coronary heart disease when a variety of other factors were considered.

Another paper to hit the scientific community was called the Framingham Heart Study. This study, commissioned by Congress, started in 1948 and included a detailed assessment of nearly 6000 individuals all living in Framingham, Massachusetts. It also included other factors that might lead to heart disease; obesity, smoking, and lack of exercise. It, too, found a link, albeit a weak relationship between consumption of dietary cholesterol and heart disease. However, if you read carefully, you’ll also learn that something of an anomaly was discovered. A former director of the Framingham Heart Study, Dr. William Castelli, may have sensed the studies’ contribution to groupthink and attempted to clarify. He stated, “In Framingham, we found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories, also weighed the least and were the most physically active.” Finally, being ‘physically active’ and in good physical shape was given some weight. The study also hinted at the strong genetic component of individual cholesterol levels. But none of this would be heard.

By 1995, it was too late to set the record straight. Government, the processed food industry, the medical community, the pharmaceutical companies, the media with their clickbait headlines, and my mother were all singing in unison- eggs are evil. Eggs represent an existential threat!

Yet, these research papers, however flawed, started a revolution. Literally billions of words, thousands of dubious products, millions of medical tests, billions of statin drugs, and an anxious mother was the result. It was all settled. For the egg industry, the fallout was simple. The weakest went bankrupt. For the dairy industry with its complicated government controls, unmarketable milk was turned into cheese. Eventually, so much cheese was stockpiled, it was given to schools to be fed to the kids not yet worried about their cholesterol levels.

Such is the nature of research. A hypothesis is posited, research results in data, theories are developed, papers are written, media attempts to explain it, and science is advanced. It’s a wonderful rational process and nearly always benefits humankind. But even scientists are human and subject to making errors, holding strong biases, and some have even been caught fudging a bit to prop up a wished-for narrative. But as we’ll see, our natural world is immensely complicated, and human behavior is somewhat predictable. Humans are prone to ‘confirmation bias’ and ‘groupthink,’ which contributes to the confusion. That sometimes, a perfect storm gathers that obfuscates the truth, which leads all of humanity to follow a rabbit down the hole.

The Answer is Highly Processed Substitutes

In free-market systems, innovators and risk-takers are always looking for opportunities. That is nearly always a good thing. If sugar is bad for you, then we’ll figure out a way to make our sugary sodas sugar-free. With gifted marketing folks given budgets rivaling that of the GNP of mid-tier nations, soda companies can convince the world that a can of soda is the equivalent of a glass of water. Zero everything!

So it must have been with some delight when the processed food folks realized that Humpty-Dumpty had been pushed from the wall and needed to be replaced- pronto. Soon grocery store shelves were full of products that addressed the evils of fatty cholesterol-laden food.

Since we insist on spreading something on our bread, the magicians of industrial food came up with a product called ‘margarine.’ So good was margarine, they claimed you couldn’t tell the difference between it and butter. How pleased the butter eating public must have been to enjoy something that tastes like butter, looked like butter, spread like butter, and sat in the cooled butter display case. The package boldly stated as fact, as good as butter without all the nasty dietary cholesterol. “Don’t fool with mother nature,” they lectured. In a most memorable TV advertisement, Mother Nature herself, played by a stern-looking woman, was seen having been entirely fooled by an industrial food concoction called ‘I Can’t Believe It’s Not Butter.’ She was not happy haven been duped, but she loved the trans-fat-laden margarine.

Out with nature’s natural food and in with highly processed foods. Soon, concoctions of chemicals cleverly stirred together without the bad stuff yet providing our senses the idea that we are still enjoying the old stuff. We didn’t much notice or care that many of the ingredients were there for presentation value. Stuff to make it stick together like butter and be smooth and creamy to spread like butter and taste just like butter without any actual dairy product in the brew. Only later would we come to understand that this new butter substitute, margarine, typically contained a heaping of heart-damaging trans fats. Eventually, the makers of these products would be called out for all the trans fats. Until then, my mother was spreading nothing but margarine on her lunch sandwiches.

Food companies, startups, and wall street soon grew to see the size of the opportunity. They hired bright chemical and biological researchers and gave them white coats and high powered electron scopes and told them to develop substitutes.

I imagine a scene where the director of research walks into a meeting carrying a single ordinary egg. The chief demonstrably lays it on a sterile stainless steel table and slowly addresses her team. “Ladies and Gentlemen. Today we embark on a new journey. A journey so critical that the well being of all humankind is at stake. Men and women are dying of heart disease at alarming rates because of cholesterol and fat in their diet. We all know the likelihood of the average person voluntarily changing their diet (a few snickers could be heard.) Since that is unlikely, we must offer substitutes.”

The chief continued, “Research has discovered a link between this egg (she points with disgust at the lonely egg on the table) and plaque buildup on the arteries of men and women leading to atherosclerosis.” She pulls out a visual that shows a blood vessel clogged like a kitchen sink. “Just this morning, the CEO gave us the go-ahead and a three million dollar budget to develop a new product. A substitute egg.” Several researchers looked at each other with slightly tilted eyebrows. The chief continues, “Our substitute egg must look like an egg, taste like an egg, and be prepared like an egg- well a scrambled egg.” Some chuckles were heard as the assembled attempted to imagine the magic of creating an eggshell. “In every regard, the egg-loving public shall enjoy our egg as much as any egg nature has ever provided.” “Any questions?” she asks. One small hand emerged with a question. “Mam, what about the nutrients of this new product. Does it need to reflect that of an egg from nature?” she asked. “Good question. Marketing believes that if we include an industry solution of your standard off the shelf synthetic vitamin pack. They will plaster ‘fortified’ on the packaging, we’ll have a product that will sell like hotcakes,” the chief concluded as she closed the meeting. “We’ve already paid the AHA for the right to place ‘Heart Check’ on the packaging. Let’s get to work.”

Today, we have the dubious benefit of eating an egg substitute with something like 30 different chemicals carefully co-joined to resemble an egg, albeit somewhat poorly. The scientist did their best, but an egg is hard to replicate. But Humpty-Dumpty had fallen, well pushed actually, and couldn’t get up. My mother walks right past the egg cooler at the grocery store to the display right next to it. That’s where she’ll find the substitutes.

Pharmaceutical Companies Smell Blood

The pharmaceutical companies were not going to let industrial food folks get all the spoils. They, too, started to stir some ingredients together and came up with various forms of statins to reduce the cholesterol count of those with high cholesterol.

With heart disease being the leading cause of death in America, the pharmaceutical industry was already pumping out drugs to treat coronary disease and prevent heart attacks. But it wasn’t until cholesterol was accused as the rotten egg that they went to work on developing anti-cholesterol preventive medicines. The most successful being a class of drugs known as ‘statins.’ Statins would become the most profitable category of drugs in all of history. It is estimated that one trillion dollars of statins will be sold worldwide in 2020.

In 1972, a Japanese biochemist discovered a chemical found in a particular type of mushroom that would inhibit certain microorganisms from forming into other organisms. These ‘inhibitors’ prevented the maintenance of cell walls, therefore, inhibiting their formation. In 1976, the Brits had stumbled upon essentially the same mechanism, which resulted in a compound called Mevastatin. Fortunately, Mevastatin was never marketed because it caused muscle deterioration, tumors, and even death of laboratory dogs.

While the scientific community was committed to removing eggs from our future, all that was left was its colorful history and significant contribution to cultures everywhere.

A Brief History of the Egg

Historians believe it was the Chinese that first domesticated the chicken for purposes of enjoying their eggs around 6000 BC. Some records exist that the Egyptians and Romans used eggs for baking, having discovered the eggs’ ability to act as a binding agent in bread and cakes. Domesticated chickens didn’t arrive with Columbus, but they did come on the very next boat.

There is something about the shape of the egg, its conical sphere wider at the bottom, slowly tapering towards the top, which makes it so compelling. Similar to a round sphere or a ball but just different enough to make it interesting. So also thought the ancients. The cultural significance of the egg over all of recorded history is perhaps without equal in the category of food.

I recall a story out of the Midwest and reported on CNN. A junk dealer made a bid of $14,000 for someone’s entire pile of junk. This particular dealer would typically take the trinkets that contained gold or silver and have them melted down to reclaim the precious metals to make a few bucks. Just before he was to box up a collection of trinkets to be melted, he carefully examined one final time an item that looked like an ornamental mantelpiece complete with three very ornate legs suspending what was an object shaped like an egg. In a long shot, the junk dealer ‘googled’ ‘egg’ and the name of “Vacheron Constantin,” which he had found inscribed on the object.

One link led to another, which finally led him to the conclusion that he might possess something rare and precious. It turns out that he owned an original Russian Faberge. These beautiful eggs were not just any Faberge. This particular trinket was the ‘Third Imperial Easter Egg’ made by Faberge for the Russian Royal Family. One of only 50 made for the Royal family; this particular one was number three and worth nearly 33 million dollars. And that is how an unsophisticated junk dealer from the Midwest came into possession of a piece of art created to represent the observance of Easter and a love token. That’s one very expensive Easter egg.

The very first Easter Eggs are thought to have been painted by early Christians in Mesopotamia (modern-day Iraq). They painted them red to signify the blood of Christ. The tradition expanded and involved to where today, the Easter Egg is a significant component of celebrations across the globe. So strong is the Easter Egg, even attempts to de-sanctify it as a healthy food source has not diminished its symbolic power. Americans consumed $16.4 billion of multicolored plastic eggs filled with candy, chocolate bunnies, marshmallow Peeps, and other Easter holiday staples in 2015, according to the National Food Federation. In contrast, the egg industry sold 9.4 billion dollars worth of production in 2019. Fill a plastic shell resembling an egg with candy and chocolate and other sugary morsels, sell billions of dollars of them, and no one raises an eyebrow.

An Easter Egg is just one symbolic use of the egg recorded in history. Many cultures saw the eggs as a symbol of fertility. Several went so far as hanging eggs from temple doorways as an offering to the fertility gods. In ancient Iran, brides and grooms exchanged eggs, and in France, the bride would crack an egg before entering into her new home. Ancient Chinese would use eggs to divine the future. They would paint eggs, boil them, break them, and carefully read the ‘cracks’ to reveal the unknown.

The Egg as a Food Source

The egg is unique in all of nature. The nutrient profile is profound in its completeness and complexity. A single egg contains 75 calories, 7 grams of high-quality protein, 5 grams of fat, and 1.6 grams of saturated fat and a large variety of vitamins, minerals, carotenoids, and 187mg of dietary cholesterol per large egg. Carotenoids are known for reducing the risk of macular degeneration and the disease-fighting attributes of lutein and zeaxanthin. You can legitimately call an egg ‘brain’ food in that brain development and memory may be enhanced by the choline content of the humble egg. The egg contains no carbohydrates, no sugar, and no gluten.

Just after World War II, annual egg consumption stood at around 422 eggs per American. Egg prices were relatively low, and farm and breeding practices were substantially improving egg production. Americans were also dying of cardiovascular disease. The leading cause of death at the time.

There is no other food source with a history as rich as the egg. Yet, within just a few years, the egg became unwelcomed in American kitchens. Between 1950 and 2011, egg consumption in America decreased by nearly 40%. Had not the continued falling of egg prices and rising incomes, the decline in consumption likely would have been worse. Most food experts agree that the consumer’s concern about the egg’s contribution to heart disease was the major contributor to declining consumption.

So over several decades, the mighty egg with a history of thousands of years providing human sustenance, to say nothing of its rich cultural heritage, fell and cracked into a sort of science purgatory. That might have been a just end to a proud legacy if we had gotten the science right. But we didn’t. It was as if a rogue prosecutor convinced a gullible jury that Humpty-dumpty was guilty on the equivalent of a rumor. Like many rumors which started with a morsel of truth, the humble egg soon morphed into a mythical killer. Poorly conducted research had taken on a life of its own. Soon, many were invested in a particular outcome; the food industry, the AHA, the National Institute of Health, the pharmaceutical giants, nothing could stop a guilty verdict.

The role of government in the pushing Humpty-Dumpty off the wall

To convince Americans of anything, it’s best to start with a freshly baked apple pie and a healthy public relations budget. When something as apple pie as the American Health Association and the National Institute of Health team up to publish nutritional guidelines, we best pay attention. The guidelines relied heavily on Dr. Ancel Keys and his infamous Seven Countries Studies. That was the study that took the eating habits from seven countries and claimed a correlation between a diet high in saturated fats and cholesterol with heart disease. It would become the most seminal study conducted to date on eating habits and the effects on health.

With the new dietary guidelines, the AHA, the National Institute of Health, and the Senate Committee on Nutrition changed the way Americans related to their food. Congressional hearings were held in 1976, where testimony revealed that 98.9 percent of world nutrition researchers all agreed; heart disease was caused by foods high in fat and high in cholesterol. The bipartisan committee agreed, and new dietary guidelines were published. Increase your carbohydrate intake and decrease your fat intake. Soon my mother was told that nine out of ten doctors also agreed. Cut out the eggs, the dairy, the red meat, and you’ll never die from heart disease.

The train was rolling so smoothly that by 1985, the AHA and the National Institute of Health rolled out a slick national campaign called “National Cholesterol Education Program.” It is still in existence. The goal was simple; convince Americans to reduce their cholesterol consumption. Millions of dollars were spent. So convinced of these substantial efforts, the then AHA president claimed that if the dietary guidelines were followed, atherosclerosis would be “conquered” by 2000. We were one step closer to the fountain of youth.

In 1988, the AHA knew they had a moneymaker. They threw out their long term corporate by-laws preventing them from selling sponsorships and started selling sponsors to a slick new campaign called ‘Heart Check.’ Even the orange producers of Florida got hoodwinked out of $200,000.00 for the exclusive right to put the AHA ‘Heart Check’ symbol on its packaging. If you grew oranges in California, you were out of luck.

Nearly every food package soon claimed how healthy it was based on two criteria; low fat and no or low cholesterol. And if you were an egg or butter- well, so sorry. Some politicians even considered forcing the egg industry to warn egg eaters of the dangers by placing images of clogged arteries on the egg carton as if it were as dangerous a killer as cigarettes. In their opinion, what was needed was more fear.

Would anything put Humpty-Dumpty back together again? A resurrection seemed unlikely. Nary a word was uttered in support of the egg. Who dared? A few tried. Some did suggest that human health was more complicated than just blaming eggs and consuming highly processed food and swallowing a statin pill a day. Dr. Atkins, a New York physician, tried by suggesting that we look at carbohydrates a bit closer. And if weight loss is your goal, then consider removing some of the carbohydrates from your diet. But he was quickly labeled a ‘quack.’ Other ‘charlatans’ would come and go. Today, we’d call them ‘deniers.’ In some cases, their contributions to nutrition science are finding a more receptive audience today.

Except for bankrupt egg producers, few lamented the plight of the mighty egg. My mother, adjusted by reaching for margarine full of trans fats, Special K with a paid-for AHA ‘Heart Check’ sticker, vitamin D fortified skim milk that tasted worse than water, and egg beaters fortified with a few synthetic vitamins instead. Despite the ‘settled’ nature of things, a few rubes kept eating eggs despite the apparent overwhelming evidence. But the smart folks believed it hook, line, and sinker because- well because 98.9 percent of nutrition researchers said so.

With near unanimity of belief possibly the result of the most successful PR campaign ever choreographed, one big question still hung out there like a pinprick to a balloon. Does a low-fat, low cholesterol diet prevent heart disease? No. There was simply no evidence that it does.

Eventually, new dietary guidelines were produced in response to better research. The new guidelines still suggest some moderation. And if you’re a diabetic, some research suggests you carefully monitor your intake of foods high in fat and cholesterol. Finally, Humpty-Dumpty is back on the wall, and the low-fat no cholesterol nonsense is over.

So what went wrong?

Just how does nine of ten doctors come to agree with a very steamy dog pile of science? Or what about the 98.9 percent of the world’s nutrition researchers who claim to all sing in perfect harmony? Suffice to say that I know neither the exact question they all allegedly agreed too or who tallied up the results. But it’s in the congressional record that the sheer overwhelming nature of peer agreement was so persuasive that it resulted in a bi-partisan consensus that kept the ruse going and the money flowing.

How Human Behavior Contributed


“Groupthink,” social psychologist Irving Janis, the man who coined the term, says, “occurs when a group makes faulty decisions because group pressures lead to a deterioration of “mental efficiency, reality testing, and moral judgment.”

Ouch- he just insulted every one of us. Nearly everyone exists within a group or two. In a group, any group, the pressure from that group can lead us astray. We are likely to act differently, less independently, than if we’re outside of the group. I’ve seen it on the playground, in churches, on twitter, and in TV newsrooms. We can all become corrupted. Our desire to be liked, to get along, and to stay safe in the fold becomes, perhaps, more important than personal integrity and independence. Maybe there is something to be said for ‘go along to get along.’

Unfortunately, the side effects of groupthink are serious. Groupthink will ignore alternatives and quickly, collectively, dehumanize other ideas and other groups. Groupthink tends to insulate the group from outside opinions. It also tends to create a false sense of harmony and coherence, which comes at the expense of accurate analysis and critical evaluation. In the safe bosom of the group, members only see the ‘rightness’ of their cause. We no longer need to spend energy developing our arguments as we possess the moral certitude to go straight to disgust or personal attacks with our ideological opponents. We become intellectually lazy.

Noble Cause

A manager of a food industry conglomerate once told me that they were just trying to feed the world as the rationale for why the industry shouldn’t be held to the same standards as other industries. The ‘feeding the world’ meme is undoubtedly noble, but it was a purpose the industry itself was pursuing and possibly a construct of a savvy PR department. And when convenient, it was used to rationalize poor behavior. This comes close to an example of what is known as the ‘Noble Cause’ phenomenon.

Most are likely to agree that it is immoral for an individual, for personal reasons, to lie, cheat, or steal. The motive is to use corrupt means to gain personally. When an individual involved in a moral cause, seeks to use any means possible to advance the cause, noble cause corruption becomes possible. This behavioral phenomenon is the fodder of many books and the intrigue of some great movies. There is something noble when ‘stealing from the rich and giving to the poor.’ Just ask Robin Hood. As long as what you steal doesn’t benefit you personally, then taking is entirely justified. The ‘ends justify the means.’ It is morally fulfilling but will likely lead some to a sense of moral superiority.

Confirmation Bias

In a Senate hearing room recently, a senator was debating climate science with several scientists who he deemed ‘deniers.’ As evidence of man-made climate change, this senator used the example of unusual snow accumulation last winter in his home state. A personal observation made even more real by human behavioral phenomena known as confirmation bias. A particularly nasty winter simply confirmed his bias. The senator did not seem to enjoy being told that his state suffered many other brutal winters, and a particularly ugly winter was experienced in 1750. A winter far more severe than the winter he experienced.

‘Confirmatory bias’ is a tendency to search for or interpret information in a way that confirms one’s preconceptions, leading to statistical errors. The University of Iowa dug deeper into this psychological phenomenon and released a study in 2015. In that study, they also uncovered what they termed the ‘explanation effect.’ When their test subjects were asked to predict a particular outcome and to put that prediction in writing stating their rationale, the subjects were more likely to cling to their predictions in the face of evidence to the contrary. The act of putting into writing one’s belief substantially hardens the convictions of that belief. It becomes manifestly more difficult to admit your error. Is it also possible that the ‘explanation effect’ plays a roll in academia’s obsession with global warming?

Linus Pauling, a brilliant chemist, and Nobel Prize winner, touted the benefits of taking massive doses of vitamin C and wrote a book about it. My father read the book and became a believer. To his dying day, he’d vigorously promote the notion that massive doses of vitamin C have substantial health benefits even in light that Linus Pauling’s findings have been substantially debunked. After much research, there is no substantial evidence that massive doses of vitamin C benefits anyone except possibly the manufacturers of vitamins. I am quite certain that my father was unwilling to read more recent research on the topic and was quite satisfied that he possessed all the knowledge necessary to maintain his belief. To change his mind after all he’s said and written was unlikely.

Many conspiracy theories have their roots in confirmation bias. If my political disposition is not to trust authority as represented by, let’s just say, the government, confirmation bias would suggest that I am more likely to believe that the horrendous events of 9/11 were a giant conspiracy cynically designed by foreign and possibly our own government. Any bit of unknown or potentially ambiguous information becomes fodder that emboldens their convictions.

Confirmation bias knows no limits. It affects both sides of any argument and is often used as ammunition to taint the other side’s logic. Many of us are more than willing to hang onto a preconceived notion ignoring new evidence even if it were to cost us money. Confirmation bias is known to influence what it is we read and watch. If you have progressive leanings, you are likely to read left of center blogs and news sites, and inversely, if your politics are to the right, you’re more likely to watch and read things that you find yourself agreeing with.

Our natural world is a collection of extraordinary complex systems that we humans have been attempting to understand since we were imbued with the ability to ask questions. Our efforts through scientific endeavors have just begun to reveal that complexity. If understanding were represented by layers, science has no idea how many tiers are left. Expose one layer, and it reveals a multiple of new layers not previously conceived. Yet, in our hubris, we observe, test, record, theorize, publish, create mandates, and claim it all settled. Settled? Settled science. Where have I heard that phrase before?

Some weeks ago, I engaged a neighbor in a discussion on what it means when science claims something is settled. He seemed quite taken by the notion that 97% believe in something, and he gave that enormous weight. A good rationale for concluding something likely to be true. After all, who doesn’t want to be part of the majority? You’d have to be willing to claim a lot of very smart people are wrong.

So I asked him, “What percentage of scientists believe the theory of relativity?”

“I’d imagine that is nearly all of them. Maybe 100 percent,” my neighbor answers.

“Of course and for a good reason. We experience gravity every moment of our lives. It keeps us in bed. It’s what keeps my scrambled egg in a frying pan. Gravity is critical to much of life best I can tell. Now, if I ask how many believe in Einstein’s theory of relativity as the final word of how gravity works, a few hands might come down. Would you agree with me?”

“I don’t think so. I don’t believe there is any real challenge to the theory of relativity.”

“Well, actually there is,” I counter. “You’ll find a few astrophysicists and quantum physicists who have been troubled of late by some unexplained anomaly to the theory of relativity as observed deep in space. Something to do with dark matter and dark energy and antimatter. For these folks, what was ‘settled’ now appears a bit unsettled. Predictably, other scientists have quickly cast doubt on these renegades and claim the theory still safe.”

My neighbor looked at me a bit skeptically as he should. I hope he went home to do a little of his own digging.

The pursuit of knowledge is a pesky, persistent thing. It will go on. That is just the nature of our curious being. That has been the history of scientific inquiry. Something will be discovered that will turn much of what we thought we knew on its head. Fortunately, many scientists pursue knowledge for its sake alone. Political agendas and belonging to groups and gaining peer admiration is not their goal. Their commitment is to search for truth wherever that leads. With courage and healthy skepticism, they know that our natural world, both near and far away, will throw us a few more curves before it floods or burns or whatever the Illuminati believe will be the end of things.

I am not a scientist nor particularly well educated. I’ve lived long enough to have heard many predictions. Some of them were said to scare me. Some came from very smart people.
