And then there are the indignation junkies

In some people, a hedonic gratification pattern can be achieved simply by entering certain frames of mind. For example, the cyclical jolt from gambling can be a genuine addiction, requiring as much effort to break as cocaine or kicx. Habitual thrill seekers, video game potatoes, and Wall Street “wizards” have all been shown to follow similar patterns. Once aboard the roller-coaster, they cannot let go. One mild version can be seen in those riveted to spectator sports… and then there are the indignation junkies. People who regularly get high off self-righteousness and sanctimony. You know the kind—we all do.
