For a collection of moving sources with velocities randomly distributed, the classical Doppler effect predicts that half of the sources appear redshifted and half appear blueshifted. When relativistic speeds are involved, the transverse Doppler effect introduces a preponderance of redshifts over blueshifts. In this article it is shown that the size of the effect (i.e., the ratio of redshifts to blueshifts) can be calculated in a straightforward manner. For quasars, redshifts as large as 3.5, corresponding to velocities of 0.91c, have been observed. At this speed, randomly directed motions will produce almost an order of magnitude more redshifts than blueshifts. This consideration should be mentioned in discussions of whether quasars are ''local'' rather than ''cosmological'' objects.
