Someone (Tegmark?) used this kind of approach to show the Fermi paradox isn’t so surprising. If you take a uniform log prior over intelligent civilization density, you quickly remove the end where there would be multiple species in the solar system, and then it’s not much of a space until you’re below 1 civ per Hubble volume...
Thanks, this is most useful.
