Refers to a situation where opposing attitudes, beliefs, identities, interests, norms or values coexist. This can lead to an active disagreement between people. Conflicts are likely to arise when individuals or groups in a given decision-making process feel their values are being ignored; or when they cannot agree on the underlying value rationality, or the way in which values will be integrated, traded-off or reconciled to inform a given decision. When different values collide in a decision-making situation, the conflict can be described as a value conflict.
