The interplanetary-scintillation visibility of extragalactic radio sources, defined as the fraction of flux density originating in compact components with angular size less than about 1 arcsec, is statistically shown to increase with decreasing flux density and decreasing overall angular size. These relations can be satisfactorily explained if a majority of extragalactic radio sources have fine structures in between those found in recent high-resolution studies of Cygnus A and 3C 33 and if most of the weaker sources are located farther away. It is also suggested that the angular size of compact components found by the method of interplanetary scintillations refers to different structures in radio sources at different redshifts, and their use as 'rigid rods' for cosmological studies should, therefore, be treated with caution.
