The problem of QSO-galaxy associations has been analysed1,2 by taking into account different classes of QSOs with the conclusions that: (1) the strong excess of 3C QSOs near bright galaxies3 is not confirmed by larger QSO samples, which do not show any tendency towards QSO-galaxy associations, so that the 3C QSOs appeared as a statistical fluctuation1.
