It is well-known that the knowledge of a group is not the same as the union of knowledge states of the group members. Let’s consider several two examples. If an agent A knows that a > b and if an agent B knows that b > c for some real numbers variables a, b and c, then together these agents know not only a > b and b > c, but also a > c. If, in another case, A knows that a ≥ b and B knows that b ≥ a then together they know also that a = b. One can then state that the power of the collective knowledge exists owing to the inconsistency of knowledge of its members.
