Abstract
Via numerical experiments, we show that the ∼10%–20% passive fraction seen at z ≳ 3 is consistent with galaxy star formation histories being maximally correlated stochastic processes. If so, this fraction should reflect a time-independent baseline that holds at any epoch or mass regime where mean star formation rates are rising. Data at

and z ≲ 0.5 bear this out, as should future James Webb Space Telescope observations.
