The passage around this formula
A skeptical reader’s first move should be to ask whether that headline number could be sampling noise dressed up by a generous threshold. It is worth actually running that check rather than asserting an answer to it. Under a null model in which a classifier’s selections are entirely independent of label position — no cognitive bias, no architectural quirk, nothing but content — the expected share of selections landing in any one third of an evenly split label list is = 1/3 , and with n = 3000 independent trials per dataset the standard deviation of that observed share is = 0.0086 , well under one percentage point. The paper’s own forty-percent threshold…
