Knowing that a fact is true is not the same as knowing how to do it

In short: You can memorize every specific fact about riding a horse without ever actually being able to mount one. This distinction defines declarative knowledge: the awareness of facts expressed through sentences. Unlike practical skills or first-hand familiarity, this type of information is context-independent and can be stored in books or on computers.

Declarative knowledge, often called "knowledge-that," refers to an awareness of facts that can be expressed in sentences. Unlike practical knowledge—which involves skills like riding a horse—or knowledge by acquaintance—which is first-hand familiarity like the taste of chocolate—declarative knowledge is context-independent. It can be stored in books, on hard drives, or as explicit memory, and is not tied to a specific purpose or use.

In the field of epistemology, the "analysis of knowledge" seeks to break down declarative knowledge into its essential components, much like a chemist identifies elements in a sample. The traditionally influential "justified-true-belief" theory posits that knowledge requires three elements: a subjective commitment to a claim (belief), an objective state of reality (truth), and a rational basis for that belief (justification). However, this standard view faced significant challenges in the late 20th century following counterexamples by Edmund Gettier, leading to modern debates over whether knowledge requires additional components, such as reliable cognitive processes or the absence of contradicting evidence.

While rote memorization can produce declarative knowledge, it is often more advantageous to integrate new information into wider structures. In medical education, for instance, researchers have explored how "Case-Based Learning" (CBL) helps bridge the gap between declarative knowledge (facts) and procedural knowledge (skills). A study involving 1,886 medical students found that using e-CBL—which combines anonymized patient cases, textbook material, and simulated seminars—led to a significant improvement in clinical examination scores between 2013 and 2015. This suggests that while declarative knowledge is a foundational building block, its true value often lies in its ability to guide problem-solving and decision-making in practical contexts.
