Anger causes a reduction in cognitive ability and the accurate processing of external stimuli. Dangers seem smaller, actions seem less risky, ventures seem more likely to succeed, and unfortunate events seem less likely. Angry people are more likely to make risky decisions, and make less realistic risk assessments. In one study, test subjects primed to feel angry felt less likely to suffer heart disease, and more likely to receive a pay raise, compared to fearful people. This tendency can manifest in retrospective thinking as well: in a 2005 study, angry subjects said they thought the risks of terrorism in the year following 9/11 in retrospect were low, compared to what the fearful and neutral subjects thought.
