A modified Wilson action with an additional chemical potential for the number of negative plaquettes'' is used to study the role of {ital Z}{sub 2} artifacts in SU(2) lattice gauge theory and their possible influence on large-scale physics. The phase diagram of the model with modified action is studied. We show that large-scale objects, e.g., Wilson loops and their ratios, can be strongly influenced by lattice artifacts.
