“it turns out that your brain on grievance looks a lot like your brain on drugs. In fact, brain imaging studies show that harboring a grievance (a perceived wrong or injustice, real or imagined) activates the same neural reward circuitry as narcotics.”

“in substance addiction, environmental cues such as being in a place where drugs are taken or meeting another person who takes drugs cause sharp surges of dopamine in crucial reward and habit regions of the brain, specifically, the nucleus accumbens and dorsal striatum. This triggers cravings in anticipation of experiencing pleasure and relief through intoxication. Recent studies show that similarly, cues such as experiencing or being reminded of a perceived wrong or injustice — a grievance — activate these same reward and habit regions of the brain, triggering cravings in anticipation of experiencing pleasure and relief through retaliation. To be clear, the retaliation doesn’t need to be physically violent—an unkind word, or tweet, can also be very gratifying.”

“similar to the way people become addicted to drugs or gambling, people may also become addicted to seeking retribution against their enemies—revenge addiction. This may help explain why some people just can’t let go of their grievances long after others feel they should have moved on—and why some people resort to violence.”

“Trump’s unrelenting efforts to retaliate against those he believes have treated him unjustly (including, now, American voters) appear to be compulsive and uncontrollable. The harm this causes to himself and others is obvious but seems to have no deterrent effect. Reports suggest he has been doing this for much of his life. He seems powerless to stop. He also seems to derive a great deal of pleasure from it.”
…
“Like substance addiction, revenge addiction appears to spread from person to person. For instance, inner-city gun violence spreads in neighborhoods like a social contagion, with one person’s grievances infecting others with a desire to seek vengeance. Because of his unique position and use of the media and social networks, Trump is able to spread his grievances to thousands or millions of others through Twitter, TV and rallies. His demand for retribution becomes their demand, causing his supporters to crave retaliation—and, in a vicious cycle, this in turn causes Trump’s targets and their supporters to feel aggrieved and want to retaliate, too.”
…
“Political parties and interest groups have come to rely upon inflaming grievances and stoking vindictiveness to generate donations and motivate voters. Media, entertainment and social networking giants also rely upon grievance and revenge-based content to attract viewers and users and increase advertising and sales. More people need to become savvy about how, why and for whose benefit they are being made to feel aggrieved and must decide to stop dealing in the drug of their own destruction.”
