There has been much debate about the use of catharsis in the reduction of anger. Some scholars believe that "blowing off steam" may reduce physiological stress in the short term, but this reduction may act as a reward mechanism, reinforcing the behavior and promoting future outbursts. However, other studies have suggested that using violent media may decrease hostility under periods of stress. Legal scholars have linked "catharsis" to "closure" (an individual's desire for a firm answer to a question and an aversion toward ambiguity) and "satisfaction" which can be applied to affective strategies as diverse as retribution, on one hand, and forgiveness on the other. There's no "one size fits all" definition of "catharsis", therefore this does not allow a clear definition of its use in therapeutic terms.
