Hard Problem of Fact

The dilemma that facts are not raw, uninterpreted bits of the world, but are always "theory-laden." What counts as a fact depends on the conceptual framework you're using. A fact is a statement about the world that we agree is incontrovertible within a given paradigm. The hard problem is that when paradigms shift (e.g., from Newtonian to Einsteinian physics), old facts can become false or meaningless. This means facts are not eternal building blocks of knowledge, but temporary settlements in an ongoing negotiation between observation and interpretation.

Example: For centuries, "The Sun revolves around the Earth" was a brute fact, confirmed by daily observation. The shift to heliocentrism didn't change the raw data (the sun's motion in the sky), it changed the interpretive framework. The "fact" became "The Earth rotates, creating the illusion of solar motion." The hard problem: There is no neutral observation language. What you call a fact reveals your theoretical commitments. A fact is like a piece in a puzzle—it only has a definite shape and place relative to the picture you're trying to build. Hard Problem of Fact.

Hard Problem of the G Factor

The statistical reality that performance on diverse cognitive tests tends to correlate, suggesting a single, underlying general intelligence factor (*g*). The hard problem is figuring out what *g* physically is in the brain. Is it neural processing speed? Efficient connectivity? Working memory capacity? Or is it just a mathematical phantom emerging from the way we design tests? It's the hunt for the biological engine of intellectual horsepower, separate from specific skills or knowledge.

Example: "Neuroscientists found a correlation between *g* and prefrontal cortex efficiency. But the hard problem of the g factor remains: Is that efficiency the cause of general intelligence, or just another symptom of a deeper, still-mysterious root? It's like finding a bigger battery in smarter people, but not knowing what the battery actually powers." Hard Problem of the G Factor
