  In most global fits of the constrained minimal supersymmetric model (CMSSM)
to indirect data, the a priori likelihoods of any two points in tan beta are
treated as equal, and the more fundamental mu and B Higgs potential parameters
are fixed by potential minimization conditions. We find that, if instead a flat
("natural")prior measure on mu and B is placed, a strong preference exists for
the focus point region from fits to particle physics and cosmological data. In
particular, we find that the lightest neutralino is strongly favored to be a
mixed bino-higgsino (~10% higgsino). Such mixed neutralinos have large elastic
scattering cross sections with nuclei, leading to extremely promising prospects
for both underground direct detection experiments and neutrino telescopes. In
particular, the majority of the posterior probability distribution falls within
parameter space within an order of magnitude of current direct detection
constraints. Furthermore, neutralino annihilations in the sun are predicted to
generate thousands of neutrino induced muon events per years at IceCube. Thus,
assuming the framework of the CMSSM and using the natural prior measure, modulo
caveats regarding astrophysical uncertainties, we are likely to be living in a
world with good prospects for the direct and indirect detection of neutralino
dark matter.
