#989 - James Kimmel Jr. - Why Violence & Revenge Fantasies Feel Good

By Chris Williamson

In this episode of Modern Wisdom, James Kimmel Jr. examines the neuroscience behind revenge and its connection to addiction. He explains how psychological injuries trigger the brain's pain network, leading to a craving for retribution that, when satisfied, activates reward circuits and dopamine release—similar to patterns seen in substance abuse.

The discussion covers revenge's evolutionary roots in human societies and its modern manifestations, noting that while most people experience desires for revenge, few act on them. Kimmel explores the distinction between revenge and self-defense, analyzes how legal systems sometimes legitimize revenge under the guise of justice, and presents forgiveness as an alternative approach that can deactivate revenge-related brain networks and improve mental health.

1-Page Summary

The Psychology and Neuroscience of Revenge

James Kimmel Jr. explores how revenge operates in the human brain, explaining that it functions similarly to substance addiction. He describes how psychological injuries like insults and humiliation trigger the brain's pain network, particularly the anterior insula, creating an intense desire for retribution.

When revenge is enacted, Kimmel Jr. explains, it activates the brain's reward circuitry, releasing [restricted term] and creating a euphoric high. This pleasure fades quickly, leading to cravings for more revenge—mirroring the neurological patterns seen in substance abuse and other addictions.

Revenge in Human Evolution and Society

According to Kimmel Jr. and Chris Williamson's discussion, revenge likely evolved during the Pleistocene ice age as a mechanism to protect early human communities and enforce social norms. While historically connected to survival threats, today's revenge often stems from trivial grievances that the brain processes as serious threats.

Kimmel shares that while 95% of people experience revenge desires, only about 20% act on them. He notes that certain cultures, like those in the Caucasus, are more prone to revenge-seeking behaviors, while individual tendencies can be influenced by personality, upbringing, and environmental factors.

Distinguishing Revenge From Justice/Self-Defense

Kimmel and Williamson examine the crucial differences between revenge and self-defense. While revenge focuses on emotional punishment for past wrongs, self-defense is about rational protection from present threats. They argue that the legal system often legitimizes revenge by cloaking it in the language of "justice," leading to punitive approaches that fail to resolve underlying conflicts.

Power of Forgiveness as an Alternative to Revenge

Kimmel Jr. presents forgiveness as a powerful alternative to revenge, explaining that it deactivates brain networks associated with pain and revenge cravings. He describes forgiveness as a "superpower" that can improve both mental and physical health by reducing anxiety, depression, and stress.

He advocates for incorporating revenge prevention and forgiveness education into schools and public health policies, suggesting that teaching grievance management strategies could help prevent violent behaviors and manage what he terms "revenge addiction."

Clarifications

  • When revenge is carried out, the brain's reward system is activated, leading to the release of [restricted term]. [restricted term] is a neurotransmitter associated with pleasure and reward, creating a sense of satisfaction or euphoria. This neurological response reinforces the behavior of seeking revenge, similar to how addictive substances trigger the brain's reward pathways. The temporary pleasure from revenge can lead to a cycle of seeking more revenge to experience the same [restricted term]-driven satisfaction.
  • During the Pleistocene ice age, early human communities faced survival threats, leading to the evolution of revenge as a mechanism to protect against harm and maintain social order. This evolutionary adaptation helped deter individuals from harming the group and reinforced cooperation by enforcing norms and deterring free-riders. The instinct for revenge may have provided a survival advantage by discouraging behaviors that could jeopardize group cohesion and individual safety. Over time, this tendency to seek revenge may have become ingrained in human psychology as a way to navigate social interactions and maintain community stability.
  • In the context of revenge, trivial grievances being processed as serious threats means that the human brain can sometimes react strongly to minor offenses, perceiving them as significant dangers. This exaggerated response can trigger a desire for revenge, even though the initial trigger may not warrant such a severe reaction. This phenomenon highlights how subjective interpretations and emotional responses can influence the perception of threats and the subsequent urge for retribution.
  • Individual tendencies towards seeking revenge can be shaped by various factors such as personality traits, upbringing experiences, and environmental influences. For example, someone with a more aggressive personality might be more inclined towards seeking revenge compared to someone who is more empathetic. Additionally, the way a person was raised and the cultural norms they were exposed to can also play a role in how they perceive and respond to situations that trigger feelings of revenge. Environmental factors like social dynamics, economic conditions, and past experiences can further impact an individual's likelihood of seeking revenge in response to perceived wrongs.
  • In some cases, the legal system's approach to justice can be seen as legitimizing revenge when punitive measures are heavily focused on retribution rather than rehabilitation or restoration. This can lead to a cycle of retaliation rather than addressing the root causes of conflicts. The concept highlights a potential overlap between seeking revenge and seeking justice within legal frameworks. This dynamic can sometimes blur the lines between seeking personal satisfaction through revenge and seeking societal balance through the legal system.
  • When forgiveness deactivates brain networks associated with pain and revenge cravings, it means that the mental processes linked to feeling hurt and seeking retribution are subdued. This can lead to a reduction in negative emotions and impulses related to seeking revenge. By forgiving, individuals may experience a decrease in the psychological drive to retaliate against those who have wronged them. This process can contribute to improved mental well-being by breaking the cycle of anger and resentment.
  • Teaching grievance management strategies involves educating individuals on how to address and cope with feelings of resentment or perceived injustices in a constructive manner. This approach aims to help individuals develop skills to navigate conflicts and grievances without resorting to violent or retaliatory actions. By promoting healthy ways to process and resolve grievances, the goal is to prevent the escalation of negative emotions that can lead to harmful behaviors. The concept of "revenge addiction" suggests a pattern of seeking retribution as a coping mechanism, and teaching grievance management strategies can help individuals break this cycle by promoting forgiveness and conflict resolution skills.

Counterarguments

  • While revenge may activate the brain's reward circuitry, it's important to consider that not all individuals experience the same level of euphoria or desire for revenge, indicating a more complex interaction between individual psychology and the neurochemical responses.
  • The evolutionary argument for revenge as a protective mechanism may be oversimplified, as human behavior is influenced by a multitude of factors, and not all behaviors can be directly traced to evolutionary advantages.
  • Cultural differences in revenge-seeking behaviors may be more nuanced than presented, with historical, socio-economic, and political factors also playing significant roles in how these behaviors manifest and are perpetuated.
  • The distinction between revenge and justice is complex, and while the legal system may have punitive elements, it also incorporates principles of rehabilitation and deterrence, which are not typically motivations for personal revenge.
  • The effectiveness of forgiveness as an intervention for revenge cravings may vary widely among individuals, and some may require additional forms of support or therapy to address underlying issues.
  • The idea of incorporating revenge prevention and forgiveness education into schools and public health policies, while potentially beneficial, may face practical challenges in implementation and effectiveness, as well as varying acceptance among different cultural and social groups.
  • The statistics provided (e.g., 95% of people experience revenge desires, 20% act on them) may not be universally accurate and could vary based on the methodology of the studies from which they were derived. Further research might be needed to confirm these figures across different populations and contexts.

The Psychology and Neuroscience of Revenge

James Kimmel Jr. discusses the complex psychological and neurological underpinnings of revenge, which fuels the behavior and creates an addictive cycle akin to substance abuse, according to behavioral studies and public health data.

Revenge Activates Brain's Pain and Reward Networks, Creating Addictive Cycle

Psychological Harms Like Insults, Humiliation, and Betrayal Trigger Intense Pain and Retribution Desire

Kimmel Jr. delves into the concept of a "vulnerable brain" and revenge addiction. He explains that unlike other addictions where the substance or activity is external, with revenge addiction, the sense of victimization becomes the trigger. This type of addiction stems from psychological injuries like insults, humiliation, betrayal, and shame which activate the brain's pain network, specifically the anterior insula. Grievances can produce powerful desires to retaliate against those who have inflicted such psychological pain, creating a craving for revenge.

Kimmel Jr. also describes his own childhood experiences with bullying, pointing out the long-term pain and anger caused by humiliation and harassment. Moreover, Kimmel Jr. asserts that the psychological harms causing the need for revenge are considered significant and can activate an intense desire for retribution.

Revenge Activates Brain's Reward Circuitry, Causing Euphoric "High" and Compulsive Behavior

The brain seeks pleasure to counteract this psychological pain and finds it in the act of revenge. This gratification involves the pleasure and reward circuitry of addiction, including the nucleus accumbens and the dorsal striatum. When revenge is enacted, it releases [restricted term], providing a euphoric high that fades quickly, leaving an individual craving more—akin to the cycle of substance abuse.

Kimmel Jr. explains that craving for revenge can consume individuals and lead them to inflict harm on others as a way to feel better, describing it as an addiction where gratification comes from causing pain. This cycle can lead to compulsive behaviors, such as seeking satisfaction by acting against perceived grievances, creating a euphoric [restricted term] hit that reinforces a craving for the highs revenge can bring.

  • When someone experiences psychological harm like insults or betrayal, it activates the brain's pain network, particularly the anterior insula, causing intense emotional pain. This pain triggers a desire for retribution or revenge against those who caused the harm. On the other hand, seeking revenge can activate the brain's reward circuitry, releasing [restricted term] and creating a temporary euphoric feeling, similar to the high experienced with substance abuse.
  • The comparison of revenge addiction to substance abuse and other addictive behaviors highlights how seeking revenge can activate similar brain circuitry and reward systems as seen in drug addiction, alcoholism, and gambling. This parallel suggests that the pursuit of revenge can lead to compulsiv ...

Actionables

  • You can practice mindfulness meditation to reduce the intensity of negative emotions and the desire for revenge. By focusing on your breath and observing your thoughts without judgment, you train your brain to detach from the emotional charge of past hurts. This can help weaken the brain's pain network associated with psychological injuries and reduce the urge to retaliate.
  • Develop a habit of writing in a gratitude journal to shift focus from grievances to positive aspects of life. Each day, write down three things you're thankful for, which can range from small pleasures to significant achievements. This practice can help activate the brain's reward circuitry in a healthy way, counteracting the pleasure derived from negative thoughts of revenge.

Revenge in Human Evolution and Society

James Kimmel Jr. and Chris Williamson discuss how revenge may have evolved as a means of enforcing social norms and deterring theft in early human societies, and how it manifests in different cultures and personalities today.

Revenge Evolved to Promote Cooperation in Early Societies

Revenge might have evolved during the Pleistocene ice age as a strategy to promote cooperation within early human communities by retaliating against social norm violators or those who engaged in resource theft.

Retaliating Against Social Norm Violators or Resource Theft Protected Communities

Kimmel Jr. describes the role revenge played in protecting early human communities from threats to survival and reproduction, deterring theft of mates or essential resources by enforcing compliance with social norms.

Revenge Drive Fuels Violence Over Trivial Grievances

He also notes that grievances historically connected to survival threats, such as resource theft, have been largely replaced by more trivial and psychological grievances, like insults to one's ego. The brain processes these minor issues with an intense reaction similar to more serious threats, which can fuel unnecessary violence.

Revenge Is Felt By 95% but Acted On By 20%

Kimmel shares that while 95% of people experience revenge desires, about 20% act on them. This ratio mirrors the pattern seen in substance abuse.

Cultures Prone to Revenge Due to Social and Environmental Factors

Kimmel Jr. describes societies like those in the Caucasus with ongoing blood feuds that are built around revenge-seeking. He points out that certain societies, demonstrated by historical figures like Stalin and regions such as the American South, may have a more vengeful approach due to cultural upbringings. Williamson speculates that environmental factors, such ...

Revenge in Human Evolution and Society

Additional Materials

Clarifications

  • Revenge in early human societies evolved as a mechanism to maintain social order by deterring individuals from violating norms or stealing resources. This behavior helped ensure cooperation and survival within communities by imposing consequences on those who threatened the group's well-being. Over time, the concept of revenge expanded beyond immediate survival threats to include responses to perceived insults or psychological grievances, reflecting changes in societal dynamics and individual behaviors.
  • Revenge played a role in protecting early human communities by deterring theft and enforcing social norms. This helped maintain order and cooperation within the group. Retaliating against those who violated norms or stole resources was a way to ensure the survival and well-being of the community. By punishing such behaviors, early humans could discourage actions that threatened the group's stability and resources.
  • The shift from historically survival-related grievances to more trivial and psychological grievances signifies a change in the nature of triggers for revenge. Early on, survival threats like resource theft were primary reasons for seeking revenge. However, in modern times, minor issues like insults to one's ego can evoke similar intense reactions, leading to unnecessary violence. This shift reflects how societal norms and individual perceptions have evolved over time, influencing what triggers feelings of revenge.
  • Revenge desires are common feelings that many people experience, but acting on these desires involves a decision-making process influenced by various factors such as personal values, consequences, and societal norms. The gap between experiencing a desire for revenge and actually acting on it highlights the complexity of human behavior and the internal conflicts individuals may face. This statistic suggests that while revenge thoughts are prevalent, the majority of individuals ultimately choose not to act on them, showcasing the nuanced nature of human responses to perceived injustices.
  • Social and environmental factors can influence cultures prone to revenge by shaping societal norms and values around retribution. Factors like historical conflicts, limited resources, and cultural traditions can contribute to a society's propensity for seeking revenge. Additionally, upbringing, social ...

Counterarguments

  • The evolutionary basis of revenge as a means to promote cooperation is a theory that may not account for all aspects of human behavior; cooperation can also arise from mutual benefit, altruism, or kin selection without the need for revenge.
  • The role of revenge in protecting early human communities might be overstated; other factors such as diplomacy, alliance-building, and conflict resolution strategies could have been equally or more important.
  • The transition from survival-related grievances to trivial ones may not be universal; in some cultures, survival-related issues are still predominant, and the importance of trivial grievances could be a reflection of modern, more secure living conditions.
  • The statistic that 95% of people experience revenge desires but only 20% act on them could be misleading without understanding the context of these desires or actions, and the methodology used to obtain these figures.
  • Cultural proneness to revenge might be more complex than presented, with historical, economic, and political factors also playing significant roles in shaping societal behaviors.
  • The idea that certain societies or regions are more vengeful due to cultural upbringings could be an oversimplification and may not consider individual variation and the capacity for cultural change.
  • Environmental determinism, such as the idea that limited resources increase the likelihood of revenge-seeking behaviors, may not account for the variability in human responses to environmental stressors.
  • The suggestion that some personalities or upbringings foster revenge-seeking tendencies might not fully consider the potential for individuals to learn and choose behaviors that go against their predispositions.
  • The claim that less than 4% of the human population may lack empathy and be mor ...

Distinguishing Revenge From Justice/Self-Defense

Chris Williamson and James Kimmel Jr. explore the complex dynamics between revenge, self-defense, and the concept of justice in modern society.

Revenge Punishes; Self-Defense Protects From Threats

The discussion begins by noting the ethical confusion people may feel when trying to differentiate between seeking revenge and engaging in self-defense or setting boundaries. Kimmel and Williamson address the fact that holding someone to account is often conflated with revenge-seeking when true accountability should state the harm done without intentions of retaliation. This blurring of lines leads to the crucial distinction that while revenge is concerned with punishing past wrongs, self-defense is about protection from present or imminent threats.

Revenge Is Emotional, Self-Defense Is Rational

The podcast delves into the emotional nature of revenge, which is centered on punishment for past actions, as opposed to the rationality of self-defense. Kimmel notes the emotional component of revenge, highlighting that unlike immediate defensive needs, revenge is not rationalized by a protective instinct, but by a pathological desire to punish.

Seeking "Justice" Can Euphemistically Mean Indulging Revenge Fantasies and Causing Harm, Rather Than Restoring Fairness

James Kimmel Jr. explains that the term "justice" has been co-opted to serve dual meanings, with one being equity and fairness, and the other reflecting punishment and retaliation. He suggests that actions taken post 9/11 under the guise of "justice" were steeped in revenge, an emotional response to the attacks. Williamson expands on the dangers of cloaking revenge with the righteousness and obligation of "justice," pointing out that it can often exacerbate harm rather than reach fair resolutions.

"Justice" Language Legitimizes and Profits From Revenge Cravings

Kimmel Jr. argues that the language of "justice" is strategically used to mask intentions of revenge, whic ...

Distinguishing Revenge From Justice/Self-Defense

Additional Materials

Clarifications

  • Revenge involves seeking retribution for past wrongs, often driven by emotional impulses and a desire to punish. Self-defense, on the other hand, focuses on protecting oneself from present or imminent threats, rooted in the need for immediate safety rather than past grievances. The key distinction lies in the intent: revenge aims to retaliate for past harm, while self-defense aims to prevent harm in the present or future. Revenge is more about emotional satisfaction through punishment, while self-defense is a rational response to protect oneself from harm.
  • The term "justice" can have dual meanings in society. One interpretation is about fairness and equity, focusing on restoring balance and upholding moral principles. The other meaning involves punishment and retaliation, often driven by emotions like anger or a desire for retribution. These contrasting interpretations can lead to confusion and ethical dilemmas when seeking to understand the true nature of justice in different contexts.
  • Legal professionals being referred to as "professional revenge-seekers" suggests that the legal system, through its punitive approach, can sometimes prioritize seeking retribution or punishment over other for ...

Counterarguments

  • Revenge can sometimes be a natural and understandable human response, which may serve a social function by deterring future wrongdoing.
  • Self-defense can be emotionally driven as well, especially in high-stress situations where rational thinking may be compromised.
  • The concept of "justice" is multifaceted and can encompass both retributive and restorative elements, which are not necessarily rooted in revenge.
  • The legal system, while imperfect, is designed to provide a structured and regulated means of conflict resolution that goes beyond personal vendettas.
  • Punitive measures within the legal system can serve as a deterrent to crime and may be necessary to uphold social order and safety.
  • The notion of "professional revenge-seekers" oversimplifies the role of lawyers and the courts, which aim to balance various interests, including justice, fairness, and the rule of law.
  • Restorative justice approaches, which focus on healing and reconciliation, are increasingly recognized and implemented within the legal system, challenging the idea that it is solely punitive.
  • The legal system's approach to punishment is often the result o ...

Power of Forgiveness as an Alternative to Revenge

The power of forgiveness is presented as a transformative tool that can counteract the visceral need for revenge, not only aiding personal healing but also promoting peace on a societal level.

Forgiveness Deactivates Brain Networks Tied To Revenge, Aiding Healing

James Kimmel Jr. discusses how forgiveness can provide tangible benefits to mental and physical health by deactivating certain brain networks associated with pain and revenge craving.

Forgiveness Reduces Resentment and Urge to Retaliate

Forgiveness is likened to a "superpower" that lessens the desire for retribution and diminishes resentment, according to Kimmel Jr. He gives an example of role-playing through an app that simulates a courtroom for users to put their wrongdoers on trial mentally, satisfying the need for accountability while enabling the mental shift towards forgiveness. Kimmel explains that by deciding to forgive, it turns off the anterior insular pain network, which eliminates the pain that drives the need for revenge. This act calms the reward circuitry associated with revenge cravings and rumination, allowing one to break free from the cycle.

Forgiveness Benefits Mental and Physical Health, Reducing Anxiety, Depression, and Stress

Kimmel Jr. expounds on the substantial mental and physical health advantages of forgiveness, which functions like a "wonder drug." It reduces anxiety, depression, and stress, while also having positive impacts on bodily functions such as lowering blood pressure, reducing heart disease, and improving sleep quality. When individuals forgive, they engage their prefrontal cortex, kickstarting the decision-making processes that aid healing and allow them to move forward from past grievances.

Education and Campaigns on Revenge Dangers and Forgiveness Benefits Could Shift Societal Attitudes

Kimmel Jr. advocates for incorporating teachings of grievance and retribution management into schools and public health policies.

Power of Forgiveness as an Alternative to Revenge

Additional Materials

Clarifications

  • The reward circuitry associated with revenge cravings and rumination involves the brain's system that reinforces behaviors linked to seeking pleasure or avoiding pain. In the context of revenge, this circuitry can become activated when someone dwells on thoughts of retaliation, triggering feelings of satisfaction or relief. This cycle of rumination can strengthen the desire for revenge as the brain associates it with a reward, perpetuating the urge to seek retribution. Understanding how this circuitry operates can shed light on why thoughts of revenge can become consuming and difficult to let go of.
  • When individuals engage their prefrontal cortex in forgiveness, they activate the brain region responsible for decision-making and emotional regulation. This activation helps in processing and letting go of negative emotions associated with grievances. By involving the prefrontal cortex, individuals can make conscious choices to forgive, leading to healing and moving forward from past hurts.
  • Grievance and retribution management strategies involve techniques and approaches aimed at addressing feelings of resentment and the desire for revenge in a constructive manner. These strategies can include mindfulness practices, forgiveness-focused training, and other interventions to help individuals navigate and resolve conflicts without resorting to harmful or retaliatory actions. By promoting understanding, empathy, and healthy coping mechanisms, these strategies seek to prevent escalation of grievances and promote peaceful resolutions in personal and societal contexts. Integrating these strategies into education and public health initiatives can help cultivate a culture of forgiveness and co ...

Counterarguments

  • Forgiveness may not deactivate revenge-related brain networks in all individuals, as the process of forgiveness and its neurological effects can vary greatly from person to person.
  • Some individuals may find that forgiveness does not significantly reduce their resentment or urge to retaliate due to deeply ingrained emotions or particular circumstances surrounding the offense.
  • While forgiveness can have mental and physical health benefits, it is not a panacea and may not be as effective as other treatments for certain individuals with specific psychological or medical conditions.
  • Education and campaigns may not be sufficient to shift societal attitudes if not accompanied by broader systemic changes that address the root causes of revengeful behavior, such as social injustice or trauma.
  • Implementing grievance and retribution management in schools and public health systems may face practical challenges, such as lack of resources, resistance from stakeholders, or cultural differences in the perception of forgiveness.
  • The ...
