Archer (1912, ch. XV) argues that what matters on stage is plausibility, not demonstrable probability; that plausibility works on three planes (external manners/costume/dialect; uncharacteristic events independent of the characters' will, where chance and coincidence belong; and psychological plausibility, which he says is 'vastly the most important'); that the second plane is 'its indispensable condition precedent' for some plays; that standards differ by form (realistic drama versus romances, farces and light comedies whose charm is 'delightful improbability'); and, citing Sarcey, that audiences swallow improbable antecedents (the past) more readily than improbabilities shown now. The result is a genre-relative audit: first tag the form, then apply the strict test only where the form makes a realism promise. All of this is one author's reasoning with chosen examples; no audience was measured.
