Verdubbelingstijd van een aantal sociale fenomenen (Price, 1963, p. 6-7). De verdubbelingstijd van wetenschappelijke publikaties ligt op een hoog niveau, hoger b.v. dan het verdubbelingsritme van de menselijke bevolking. Voor geheel de wetenschappelijke produktie, opgeteld ongeacht haar kwaliteit, geldt een verdubbeling om de 10 jaar. Wanneer men een kwaliteitsnorm invoert, geldt een verdubbeling om de 15 jaar.
