The passage around this formula
…Q is the held-out probe set of size k and is m ’s response to probe q . I(m) is a dimensionless rate between 0 and 1: the fraction of probes that elicit the trait. Average I(m) within each class to get , , and = . is the article’s single most important number, because it is the rate at which the trait shows up in models that never touched the source at all — the convergence baseline , the rate any theory of pure coincidence has to beat.
