It's not really an inversion, the angry people seek out disconfirming evidence to argue against, and are only "accidentally" convinced by it.
If you ever want to ad lib anger, and you're tired of listening to Drowning Pool or HedPe, take a gambit at Magnetos Anger 1 and 2
The current research explores the effect of anger on hypothesis confirmation — the propensity to seek information that confirms rather than disconfirms one’s opinion. We argue that the moving against action tendency associated with anger leads angry individuals to seek out disconfirming evidence, attenuating the confirmation bias. We test this hypothesis in two studies of experimentally-primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity to read about a controversial social issue. Study 2 measured participants’ opinions and information selection about the 2008 Presidential Election and the desire to ‘move against’ a person or object. Participants in the angry condition reported a greater tendency to oppose a person or object, and this tendency led them to select more disconfirming information.
