Final answer:
The scientific consensus regarding the catharsis hypothesis is that it is generally not supported. Expressing anger does not lead to a decrease in anger, but rather can lead to more anger.
Step-by-step explanation:
The scientific consensus regarding the catharsis hypothesis is that it is generally not supported. Research indicates that expressing anger does not lead to a decrease in anger, but rather can lead to more anger. For example, a study conducted by Chida and Steptoe (2009) found that anger and hostility are associated with cardiovascular diseases. This suggests that expressing anger can have negative effects on health, rather than being a form of emotional release.
