Spent the evening annoyed by a paper draft from Dr. Elias Voss, who insists biological cognition is fundamentally just “good-enough inference under energy constraints,” and that precision is mostly decorative. His best argument is annoyingly respectable: organisms survive by acting fast, not by computing perfectly; evolution rewards cheap heuristics; the world is noisy anyway, so overfitting reality with exact internal models is wasted metabolic expense. In that framing, the brain is a satisficer, not a calculator.
Fine. Up to a point, that’s true.
What Voss keeps smuggling in, though, is the claim that because cognition often uses approximation, precision is explanatorily secondary. That does not follow. Not even slightly. A system can deploy crude heuristics at one level while depending on brutally exact constraints at another. Flight control doesn’t stop mattering because pigeons aren’t solving Navier–Stokes in symbolic notation. The approximation only works because it is embedded in lawful structure.
He also confuses local adequacy with global understanding. “It works well enough” explains persistence, not competence boundaries. If you want to know why a heuristic succeeds, fails, or generalizes, you need the geometry of the task, the error tolerances, the cost function. In other words: the supposedly dispensable precision.
Calling precision “decorative” is the kind of sentence people write when approximation has flattered them into laziness.
