Dr. David Serio shares his perspective on what he considers the greatest subluxation facing the profession, pointing not to mechanics but to interference in thinking and identity. He reflects on how fear, compromise, and the desire for approval can gradually shift messaging away from a clear subluxation-centered objective. Drawing from history and experience, he distinguishes philosophical certainty from exaggerated claims and emphasizes leadership maturity in communication. His message is direct: clarity and congruence are not optional if chiropractic is to remain anchored in its foundational principles.
