It is pointed out that QSOs are likely to be superluminous objects only if their redshifts are cosmological. For local models in which a large fraction of the redshift is attributed to some other cause, they are more likely to be subluminous. Unbiased searches for quasar-cluster associations should give predictable and remarkably different results for real associations in each model. It is suggested that local quasar theories might be useful in determining whether or not quasar-cluster associations are real. Quasar distances, estimated using a method described by Bell and Fort, are compared with the cluster distances estimated for the quasar-cluster associations found by Bahcall and by Bahcall, Bahcall, and Schmidt. Reasonable agreement is found for 16 out of the 22 cases.
