The passage around this formula
Done correctly, the weak principle is pure statistics: it is a conditioning operation, identical in structure to correcting a biased sample in any other empirical science. A concrete instrument in this article’s own world makes the logic exact rather than analogical. A magneto-optical trap holds a cloud of atoms by continuously discarding the ones moving too fast to be captured by the cooling beams; every atom visible in the trap already survived a velocity cut. Someone who measured only the trapped cloud and concluded “the atoms in this room are unusually cold” would be committing exactly Eddington’s error — the room is not unusually cold, the trap is unusually selective, and the correction…
