Abstract
Observational arguments suggest that the growth phases of the supermassive black holes in active galactic nuclei have a characteristic timescale yr. We show that this is the timescale expected in the chaotic accretion picture of black hole feeding, because of the effect of self-gravity in limiting the mass of any accretion disc feeding event.
