Query: Why radio quiet quasars are preferred over radio loud quasars regardless
  of environment and redshift   Evidence has accumulated suggesting the clustering of radio loud quasars is
greater than for radio quiet quasars. We interpret these results in a context
in which the fraction of radio loud quasar formation is less than or equal to
that for radio quiet quasars for all environments and redshift. Because we
assume that post-merger cold gas onto large black holes produces either a radio
loud or a radio quiet quasar, we show that for largest black hole masses that
live in largest dark matter halos, fRLQ approaches 0.5 from below but does not
exceed it, such that in rich clusters the formation of a radio loud quasar
tends to be equally likely to occur as a radio quiet quasar. In dark matter
halos with smaller mass, by contrast, radio quiet quasars are more likely to
form and the likelihood increases inversely with dark matter halo mass. As a
result, averaging over a population of radio loud and radio quiet quasars will
necessarily generate lower average black hole masses for the radio quiet
subgroup. Hence, despite the fact that the formation of radio quiet quasars is
preferred over radio loud quasars in any environment, at any mass scale, at any
luminosity, or redshift, averaging over a range of radio loud quasars will give
the appearance they are preferred in cluster environments over radio quiet
quasars. We show how this also accounts for the order of magnitude difference
in the total number of jetted active galaxies compared to non-jetted
counterparts.
