What this part means

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.

Its job in the formula

I0I_0 is part of the quantity the equation computes from the expression on the right.

Where the article explains it

I0I_0 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.

The passage around this formula

…rm(q)r_m(q) 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 IˉV\bar I_V , IˉH\bar I_H , and I0I_0=Iˉ∅\bar I_\varnothing . I0I_0 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.
