Abstract Three independent schemes are proposed for biasing galaxy formation toward luminous galaxies, early collapse, and denser protogalaxies in a universe containing a closure density of cold dark matter. Photinos, or other massive, neutral weakly interacting leptons are assumed to be the predominant dark matter species, and their annihilation in collapsing protogalactic clouds suppresses galaxy bulge formation for isolated systems. Shock destruction of H2 can occur at low redshift during the epoch of massive galaxy and quasar formation; the ensuing collapse and cooling of primordial clouds by Lyα emission results in predominantly massive star formation that should disrupt late-forming galaxies. The high rate of star formation presumed to occur during gaseous protogalaxy collapse effectively strips low-density protogalaxies by initiating a supernova-driven wind.
