The Most Dangerous Words in Medicine: “We’ve Always Done It This Way”

What will it take for us to start asking harder questions about our children’s health?

Often, it takes a life-changing experience to make someone question everything they’ve believed. A personal tragedy. An unexpected diagnosis. A moment that forces them to see something differently. 

But should it really take something so personal?

Look at the health challenges facing children today. Childhood obesity. Chronic illness. Developmental disorders. Rising autism diagnoses. These are serious concerns that deserve our attention. Although they have different causes and contributing factors, together they raise an important question:

Shouldn’t the health of our children be reason enough to keep asking questions?

We live in a society that places tremendous trust in medical institutions, established guidelines, and professional expertise. Much of that trust is well-earned. But trust should never replace critical thinking. Especially in medicine. Science was never meant to stand still. It advances through questioning, investigation, and the willingness to reconsider what we once believed.

When Listening Changes Everything

Early in his career, Dr. Brian Thornburg followed conventional childhood vaccination recommendations, much like most pediatricians. At the time, questioning those recommendations wasn’t something he had seriously considered.

But as parents began bringing him medical literature, research, and thoughtful questions, something shifted. Rather than dismissing their concerns, he began examining the evidence for himself.

As he explored the literature, he identified what he considered inconsistencies, weaknesses in study design, and unanswered questions, particularly concerning long-term health outcomes. It wasn’t simply that parents were questioning established recommendations. He began questioning the strength of the evidence behind what he had been taught. That willingness to listen and investigate gradually changed his approach to medicine.

For the majority of his career, Dr. Thornburg embraced an approach centered on informed consent and parental choice, respecting families’ involvement in decisions about childhood vaccinations.

Only within the past year did his evolving perspective lead him to stop administering vaccines in his practice. But perhaps the most important part of his journey isn’t where his thinking ultimately led.

It’s that he remained willing to reconsider what he had been taught.

The Danger of Becoming Too Certain

One of the greatest risks in medicine is believing we already have all the answers. Medical recommendations change. New research emerges. Treatments evolve. Scientific understanding advances.

Yet when physicians become so firmly attached to established beliefs that they refuse to consider new evidence, curiosity can give way to complacency.

Questioning doesn’t mean rejecting science. It means participating in it. It means evaluating research critically, recognizing limitations, acknowledging uncertainty, and remaining willing to change when credible evidence warrants it. 

True confidence in medicine should never require closing the door to new information.

Our Children’s Health Should Be Our Why

Most people have a personal reason that pushes them to question, investigate, or change direction. But when it comes to the health of our children, shouldn’t the challenges we see around us be motivation enough? We shouldn’t have to wait for a personal tragedy or life-altering experience to become curious about the factors influencing children’s health. The growing burden of chronic health conditions and the challenges families face deserve continued attention, meaningful research, and honest conversations. These concerns don’t establish a single cause, but they reinforce the importance of asking questions and seeking evidence-based answers.

The health of our children should never be something we become complacent about.

Parents Deserve a Voice

Finding the right pediatrician is about more than credentials or years of experience. It’s about finding someone who listens.

Someone who welcomes questions without judgment, takes concerns seriously, and can explain both the evidence supporting a recommendation and its limitations.

Parents shouldn’t feel intimidated or dismissed for wanting to understand decisions affecting their children’s health. A strong physician-parent relationship is a partnership built on trust, respect, and open communication. You don’t have to agree on everything to create an environment where meaningful conversations can happen. And sometimes, those conversations can change the way we think.

Medicine should never stop Evolving
Dr. Thornburg’s journey reminds us that growth often begins with the willingness to question what we’ve always believed. Being open-minded doesn’t mean accepting every claim or abandoning established evidence. It means examining information fairly, even when it challenges our own conclusions.

That responsibility is especially important for those entrusted with the health of others. Because medicine should never be about defending a position simply because it’s familiar. It should be about having the humility to keep learning, the courage to keep questioning, and the willingness to truly listen.

Our children deserve nothing less.
