Recently I have been reading about the significant increase in childhood diseases that previously had been well controlled with vaccines. There are a number of factors at play here. One is the pandemic which has reduced doctor’s visits and with it some routine vaccinations. But the most significant factor is the resistance among the vaccine deniers not just the COVID vaccine, but vaccines in general.
This is especially troubling to me. These are people, many of whom are well educated, who have chosen not to vaccinate their children or themselves. The majority of these decisions are based on misinformation which has resulted in faulty decision making. I’ve addressed this in a previous post entitled Fake News. However, I would like to address some additional issues related to what is commonly called “critical thinking”. The ability to apply critical thinking would most likely have resulted in a far smaller vaccine denial movement and fewer deaths and disabilities.
Just to start, I’m going to repeat the definition of critical thinking I used in that post. “Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.”
That post was principally geared to critical thinking in adults. I wanted to discuss how to gather information, evaluate it and make a rational decision. I’ve come to realize, that by the time we are adults our method of thinking is very close to being set in stone. If we are to make a significant impact on the way our population evaluates data and makes decisions, it must start with the children.
I believe that the two pillars of early education should be reading and critical thinking. Admittedly, I am not an educator, but I believe if you can read you can teach yourself anything. But you also need the ability to decide what you should believe. The framework for being able to make these decisions is critical thinking.
In some ways critical thinking has been taught in the past, often as the Socratic method. Elements of it have been in specific courses such as philosophy, logic, and scientific investigation. These courses are usually designed for older, advanced students who most likely have already developed these skills or have a natural inclination to pursue such inquiry and evaluation.
For most students, if they haven’t learned how to gather information, evaluate competing ideas and draw coherent, fact based conclusions by the time they are in high school, it may be difficult for them to do so. Critical thinking must be a substantial part of education from the beginning. It cannot be a separate course. It must be integrated into the way every subject is taught. Students should not just be given rote information to be memorized. They should be taught how to think and evaluate and then they should be provided with all the information necessary to make their own informed decisions.
What does this mean? It means that all sides of a topic should be covered. There should be no forbidden subjects. There cannot be an effective analysis of competing information if only one side is presented. This needs to begin in the very first years of education. After all, as Americans we want education not indoctrination.
The ability to develop critical thinking and to make informed decisions requires the exposure to all varying ideas without any value judgment being attached by the teacher. The idea of an academic “safe space” where students are insulated from hurt feelings presupposes that they are unable to evaluate competing ideas and must be protected. This is the very essence of indoctrination and should be an anathema to education.
Children need to learn that the world is not a safe place. If they are not exposed to the competing ideas, how can they be expected to evaluate and recognize the harmful ones? If they are only exposed to one side, they will come to believe that side is the only true side regardless of its value.
I will use myself as an example. There were no efforts to teach critical thinking when I was a student. We were taught that everything presented in class was the right thing, and we were not to question it. Well, this might be true in math and many science classes, but it is not true anywhere else. It was not until well into my adult years that I recognized many of the things I had been taught were the result of societal prejudices and in some cases even ignorance. As a result, like many people, I tended to defend my long-held opinions even after I recognized their weakness.
I was very slow to adopt new ideas. Many of the opinions I now hold are far different from those with which I grew up. Critical thinking was not easy for me; challenging your core values never is. We don’t want our children and grandchildren to have to suffer through the same weakness of thought that we did.
Would the evaluation of competing information that is part of critical thinking have helped prevent the wide scale vaccine denial that we are currently experiencing? Many rumors are being spread about COVID and about the COVID vaccine, just as they have been about other vaccines in the past. There were many rumors that the disease did not exist and that the deaths were faked. These rumors are still on the Internet. They never had any verifiable source and anyone taking the effort to view the data would know that there was a significant death toll early in the pandemic.
The effectiveness of COVID vaccination can easily be checked on the Centers for Disease Control and Prevention website www.COVID.cdc.gov. A study in November 2022 shows unvaccinated Americans had a 16 times (not percent) higher rate of hospitalization compared to the fully vaccinated and a study from January 2022 shows the unvaccinated had a 12.7 times higher COVID related death rate.
There were many reports about side effects of the vaccine. Checking available medical sources, it is easy to discover that while there are some side effects, there are many misstatements or exaggerations about the COVID vaccines. The side effects are similar in frequency to other vaccines and medications in general. Vaccine side effects tend to diminish as the vaccine is improved in subsequent versions. A detailed review of COVID vaccine side effects can be found on www.cdc.gov/coronavirus/2019-ncov/vaccines21.
Social media were quick to jump on every alternative to vaccination. It took very little research to realize that none of these alternatives (think Clorox) had documented medical justification and had never been effectively studied. The supposed studies that were cited were either significantly flawed or could never be duplicated or even be found. Because they had no experiencing in critical thinking, many people accepted the unsupported statements that most satisfied their desires, either politically, socially or medically and adopted them as truth. Unfortunately, this failure in critical thinking resulted in hundreds of unnecessary deaths and severe illnesses.
Ignorance Redux

On his first day in office, the new far right governor of West Virginia issued an executive order allowing for extensive exemptions from the school vaccination mandate. When taken with the nomination of a virulent anti vaxxer for Secretary of Health and Human Services, I am concerned that we are in a rush to allow our children to die of easily preventable diseases. With this in mind, I’m reposting my article The Triumph of Ignorance from last April. At that time—as you will see in the first paragraph—I had some hope. Those hopes have since been dashed.
“There are two ways to be fooled. One is to believe what is not true; the other is to refuse to believe what is true.”– Søren Kierkegaard
Saturday morning, I was reading in the newspaper about the resurgence of measles in West Virginia. I find it appalling that this disease should be returning, given that we have safe and effective vaccinations. What is next, polio, smallpox, or even plague? It is only through the unexpected veto by our governor that the ill-advised bill passed by our legislature to make all vaccinations virtually optional did not become law.
Some people may wonder why vaccinations are important. There are two principal reasons to ensure that a large portion of the population is vaccinated against communicable diseases. The first is that it reduces the individual vulnerability to disease. The person who is vaccinated is protected. But there is also a second, sometimes not well-understood, reason. That is herd immunity.
Communicable diseases require a large susceptible population to spread. When a significant portion of the population has been vaccinated the disease does not have the core of potential victims to allow spreading. This means that the vaccinated are protecting the non-vaccinated. However, it does require a large portion of the population to be vaccinated. The idea is that herd immunity will protect those who are unable to be vaccinated either due to age, allergies, or other medical conditions that would prohibit vaccination. It is never going to protect a large proportion of the population who just choose not to be vaccinated. For example, about 90-95% of the population needs to be vaccinated against measles to provide herd immunity.
So why do people who otherwise can be vaccinated choose not to be?
There are, of course, those who have true religious objections to vaccination. There are others who object to vaccination on the basis of personal autonomy. They believe their right to refuse vaccination outweighs any consideration of the health concerns of the frail members of our community.
There are many who mistrust the medical system. There were some cases in the past where unethical studies were conducted on unsuspecting populations. Given the rigorous oversight of medical research now, this no longer happens. Information about research into vaccinations and their safety and efficacy can be found on websites for the Centers for Disease Control and Prevention and the World Health Organization among others. (Website references are provided at the end of this post.)
What concerns me most are those who refuse to believe reputable medical authorities, government agencies, and mainline news services. They prefer to get their information from anonymous websites or from conspiracy theory websites that still give credence to the now-discredited 1999 study linking the MMR vaccine to autism. They completely ignore the fact that 10 of the 11 reported co-authors disavowed any part in the conclusions of the study. They also ignore the fact that the principal author was found guilty of fraud for personal gain as he was employed by the manufacturer of rival drugs. They also ignore the fact that he lost his medical license over his falsifications in this study. Yet, he is still cited in anti-vaccine literature as an expert source.
Equally disturbing is the fact that vaccine resistance has become a part of political identification. Certain reactionary political groups have, for some unfathomable reason, decided that refusing vaccination is a badge of their political allegiance. They seem to care more about maintaining their political purity than they care about science, public health, or even the welfare of their family and friends. Politicizing public health is dangerous for all of us. I’m not sure how we overcome this. It is easy to find the truth and verify it through fact-based studies, yet people refuse to do it.
I encourage everyone to work hard to ensure that our political leaders do not remove vaccination mandates for school children. For those of us of my age, we already have immunity through vaccination or prior exposure to the disease. It is our grandchildren and their children and their children’s children who will suffer through the return of these deadly diseases.
