The hypothetical existence of a good theory of mixed motives predicts many deep phenomena related to algebraic cycles. One of these, a generalization of Bloch's conjecture says that "small Hodge diamonds" go with "small Chow groups". Voisin's method [22] (which produces examples with small Chow groups) is analyzed carefully to widen its applicability. A threefold of general type without 1-and 2-forms is exhibited for which this extension yields Bloch's generalized conjecture.
