This is your brain on resentment –

December 12, 2020 –  To be clear, the retaliation doesn’t need to be physically violent—an unkind word, or tweet, can also be very gratifying. Scientists have found that 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. Although these are new findings and the research in this area is not yet settled, what this suggests is that 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.  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.

 People suffering from addiction tend to experience relationship problems and conflicts, display periods of euphoria followed by depression and restlessness, and fail to meet their responsibilities or fulfill their professional obligations. They spend long periods of time obsessing over and planning ways to gratify their cravings, and engage in the addictive behavior despite the physical or psychological harm it causes.
