Where the article explains it
Writing R for the pre-study odds that a tested relationship is genuinely true (the ratio of true to false relationships among everything a field is currently testing), for the false-negative rate, and for the false-positive threshold, the positive predictive value of a significant finding is PPV = The term worth sitting with is R .
The passage around this formula
…dynamic by expanding the numerator in Ioannidis’s framework without expanding the denominator: a hypothesis-generation agent that proposes thousands of biologically plausible mechanisms overnight lowers the effective R of the claims entering a field’s pipeline unless wet-lab or clinical capacity to check them grows to match, and a materials-discovery model that reports millions of computationally stable candidates can create exactly the appearance of abundance that the Cheetham and Seshadri critique found…
