I recently came across this article discussing a recent study on managing anger. The study examined the concept of "venting" to see if it reduced anger effectively. This concept is very much a part of our popular culture, and it goes back to the psychoanalytic model of the mind proposed by Sigmund Freud over a hundred years ago. Freud was not a good scientist, but he was a pretty amazing popularizer.
It is something of a cliche that psychology (and magick, for that matter) tends to latch onto the latest new technology as a metaphor for how the mind works. The recent fascination with computer-like models bears this out today. Before computers it was telephone switchboards, before that it was electricity, and back in Freud's day, psychoanalysis latched onto a model based on something akin to hydraulic pressure. Freud saw emotions as a kind of energy that could be bottled up ("repression") or transformed into socially viable outlets ("sublimation") rather than expressed directly in socially unacceptable ways.
The idea of venting anger comes right out of this schema. Anger is seen as a building up of pressure, like water boiling in a closed pot. "Blowing off steam" in theory reduces this pressure. But in reality, the scientific basis for this has not been supported by studies. Conditioning theory, for example, suggests the opposite, that acting out in anger feels good in the moment but reinforces acting out. This can lead to more suboptimal behavior, not less. But again, studies that directly support this conditioning model are likewise sparse.
So that is what these researchers sought to test, in order to determine how to actually reduce anger. What they found was interesting because it lines up perfectly with recommendations from ancient spiritual practices and does not exactly fit either of the modern models. The most effective methods for curbing anger were found to involve reducing physical arousal - by means of, for example, meditation. That's advice they could have gotten from the Buddhist sangha up the street, and from many other sources including Hinduism and even contemplative Christianity.
