Cognitive consonance is a comfortable and pleasant state of harmony and internal consistency arising from compatibility among a person's attitudes, behavior, beliefs, and/or knowledge. It is the opposite of cognitive dissonance.
In an Agent-Based Model, cognitive consonance can be described as a conflict resolution between agents. The resolution of conflicts and contradictions is pleasant for the mind, society or population as a whole, because group integrity is restored. Each conflict resolution reduces confusion, and is associated with a pleasant insight. The moments of discovery where cognitive consonance is reached are called the "aha," "eureka!" or "light bulb" moments. In these moments of insight, "EEG recordings revealed a distinctive flash of gamma waves emanating from the brain's right hemisphere" . They are related to a flash of neural waves, a real flood of neural activation.
