The following is an excerpt from an interview with David Brin in Wired:
But the notion of self-righteous indignation being a drug high seems to develop naturally out of recent scientific results that show that addiction is actually the most natural of human processes. You’ve heard the phrase “addicted to love.” Well, you can deliberately enter less salubrious mental states. You can deliberately go to Las Vegas, and the slot machines are now tuned to track the pattern of your behavior at the slot machine and change their rewards pattern so you start getting more rewards when it calculates that you’re about to stand up and give up and leave. So there’s gambling, thrill addiction. Well, it turns out that there’s substantial evidence that self-righteous indignation is one of these drug highs, and any honest person knows this. We’ve all been in indignant snits, self-righteous furies. You go into the bathroom during one of these snits, and you look in the mirror and you have to admit, this feels great! “I am so much smarter and better than my enemies! And they are so wrong, and I am so right!”
And if we were to recognize that self-righteous indignation is a bona fide drug high, and that yes, just like alcohol, some of us can engage in it on occasion — as a matter of fact, when I engage in it, I get into a real bender — but then say, “Enough.” If we were to acknowledge this as a drug addiction, then it might weaken all the horrible addicts out there who have taken over politics in America, and allow especially conservatism to return to the genteel, calm, intellectual ways of Barry Goldwater and William F. Buckley.
