Fugmann (1990) claimed indications for correlations between Lick galaxies and high-redshift, radio-loud background sources. We re- analyze these correlations using an improved statistical method based on Spearman's rank-order test, which we have introduced recently (Bartelmann & Schneider 1993). To our surprise, we are not able to reproduce Fugmann's results, but we detect a significant correlation between moderate-redshift sources from the 1-Jansky catalog and Lick galaxies, which increases when we apply an optical flux limit to the source sample. We interpret these empirical results in terms of an amplification bias caused by gravitational light deflection by dark matter; in particular, we argue that the observed large-scale QSO-galaxy correlations can provide a proof for the association of luminous matter (galaxies) with dark matter.
