Reality has a surprising amount of detail (2017)

Complexity, Fractals, and Limits of Models

• Many commenters connect the essay’s theme to the apparent “fractal” structure of reality: detail appears at every scale, and approximations keep breaking down.
• Others caution that “fractal” is more metaphor than physics: fine and coarse features often arise from different causes, which makes reality less tractable than an actual mathematical fractal.
• Some point to physical examples (cosmology’s “End of Greatness,” thermometers, pinball physics) to show how naïve models fail once you really care about precision.

Perception, Entropy, and Constructed Reality

• A recurring thread debates whether what we call “reality” is fundamentally external, or just models built from perception.
• One view: our perceptions are contingent, threatened by entropy; an exact 1:1 map between mind and world is neither guaranteed nor stable.
• Others push back on claims like “innate” opposite-sex attraction, attributing much of what’s taken as natural to culture.
• There’s confusion and disagreement about entropy as “just uncertainty,” with no consensus reached.

Policy, Economics, and the Danger of Oversimplification

• Several comments extend the essay to macro-systems: economies, governance, and large bureaucracies.
• Argument A: in things like national economies, “all the details matter all the time,” so top‑down plans, simplistic targets, and technocratic control tend to fail and distort their own data.
• Argument B: this same complexity is used to criticize current political efforts (DOGE) to rapidly dismantle agencies and legacy systems without understanding accumulated “edge cases.”
• Supporters of radical reform argue that the technocratic state is inherently unable to cope with complexity, so dismantling bureaucracy could allow more local, contextual decision-making.
• Critics counter that such “experiments” are non-scientific, poorly measured, and will predictably harm or kill vulnerable people; they invoke Chesterton’s Fence and legacy-system “leaky abstractions.”

Human Cognition, Meditation, and Detail Awareness

• Some highlight how schooling and professional life reward oversimplification, leading to people who become angry when reality defies their models.
• Others share practices to widen perception—meditation, deliberate attention exercises, doing the opposite of one’s defaults—as ways to notice more detail and escape “thought-ruts.”

Diversity, Teams, and Escaping Frames

• One subthread links the essay to team composition: diverse backgrounds can reveal hidden assumptions, but homogeneity can improve communication efficiency.
• Debate centers on which effect dominates, with several arguing that learning to communicate across differences is usually easier than expanding a homogenous group’s conceptual frame.
