I've written up a post offering my take on the "unreasonable effectiveness of mathematics." My core argument is that we can potentially resolve Wigner's puzzle by applying an anthropic filter, but one focused on the evolvability of mathematical minds rather than just life or consciousness.
The thesis is that for a mind to evolve from basic pattern recognition to abstract reasoning, it needs to exist in a universe where patterns are layered, consistent, and compounding. In other words, a "mathematically simple" universe. In chaotic or non-mathematical universes, the evolutionary gradient towards higher intelligence would be flat or negative.
Therefore, any being capable of asking "why is math so effective?" would most likely find itself in a universe where it is.
I try to differentiate this from past evolutionary/anthropic arguments and address objections (Boltzmann brains, simulation, etc.). I'm particularly interested in critiques of the core "evolutionary gradient" claim and the "distribution of universes" problem I bring up near the end.
The argument spans a number of academic disciplines, however I think it most centrally falls under "philosophy of science." I'm honestly surprised that other people haven't covered this question on LW before, since it feels like very centrally in the space of questions LW folks tend to be interested in. At any rate, I'm happy to clear up any conceptual confusions or non-standard uses of jargon in the comments.
Looking forward to the discussion.
Imagine you're a shrimp trying to do physics at the bottom of a turbulent waterfall. You try to count waves with your shrimp feelers and formulate hydrodynamics models with your small shrimp brain. But it’s hard. Every time you think you've spotted a pattern in the water flow, the next moment brings complete chaos. Your attempts at prediction fail miserably. In such a world, you might just turn your back on science and get re-educated in shrimp grad school in the shrimpanities to study shrimp poetry or shrimp ethics or something.
So why do human mathematicians and physicists have it much easier than the shrimp? Our models work very well to describe the world we live in—why? How can equations scribbled on paper so readily predict the motion of planets, the behavior of electrons, and the structure of spacetime? Put another way, why is our universe so amenable to mathematical description?
