Consider two fields with vast amounts of literature: medicine and law.
Medicine faces two key challenges. First, while research follows the scientific method, much of what makes a good doctor—intuition, pattern recognition, and clinical judgment—is rarely documented. Second, medical data is highly sensitive, limiting access to real-world cases, images, and practice opportunities. Theory alone is not enough; hands-on experience is essential.
Law presents a different problem: unknown unknowns. The sheer volume of legal texts makes it nearly impossible to be sure you’ve found everything relevant. Even with search tools, gaps in knowledge remain a major risk.
Compounding this is the way law is actually practiced. Every judge and lawyer operates with a shared foundation of legal principles so basic they are almost never discussed. The real work happens at two higher levels: first, the process—how laws are applied, argued, and enforced in practice. Then, at a third, more abstract level, legal debates unfold about interpretation, precedent, and systemic implications. The first level is assumed, the second is routine, and only the third is where true discussion happens.
Self-teaching is easier in fields where knowledge is structured, accessible, and complete. Many subjects are not.
