How Lying To Yourself (A Little) Can Improve Your Relationships and Make the World Feel Less Insane | Shankar Vedantam

September 29, 2025

Key Takeaways Copied to clipboard!

  • Self-deception, while potentially harmful, plays a vital, functional role in success, well-being, and maintaining relationships, contrasting with the traditional Buddhist view of delusion as a 'poison.' 
  • The utility of a delusion should often be judged by its outcomes—positive illusions in relationships or optimism in crisis are functional, whereas deceptions leading to exploitation are dangerous. 
  • Naive realism—the belief that one's own perception of reality is the only correct one—prevents empathy and understanding of why others hold seemingly outlandish beliefs, which often serve a psychological purpose. 
  • The persistent sense of self, which feels real moment-to-moment, may itself be a functional, yet potentially dangerous, self-deception that fuels greed and hatred according to Buddhist practice. 
  • The brain, as an organ of self-deception evolved through natural selection, presents a fundamental problem when attempting to use it to pierce the veil of that very self-deception. 
  • A practical technique for reducing the ownership of negative emotions is to reframe internal statements from "I am angry" to "There is anger," viewing emotions as transient meteorological phenomena rather than core identity. 

Segments

Origin of Useful Delusions Inquiry

(00:04:52)
  • Key Takeaway: Shankar Vedantam began investigating self-deception’s upside after studying the Church of Love con.
  • Summary: Dan Harris, a fan of Shankar Vedantam’s work, initiated the discussion by asking how Vedantam, a rationalist, came to explore the positive aspects of self-deception. Vedantam explained his exploration began with investigating the unusual con known as the Church of Love. This investigation revealed that self-deception could sometimes aid people, even when the con was exposed.
Church of Love Con Revealed

(00:06:03)
  • Key Takeaway: Followers of the Church of Love defended the con man even after the fraud was revealed because the relationships provided vital anchors.
  • Summary: The Church of Love was a con run by Donald Lowry, who wrote love letters as fictional ‘angels’ to thousands of men. Many recipients fell deeply in love and sent large sums of money, defending Lowry at trial because the relationships saved some from alcoholism or suicidal ideation. This demonstrated how self-deceptions can play a salutary role during moments of crisis.
Evolutionary Basis of Self-Deception

(00:08:25)
  • Key Takeaway: Biases and errors in decision-making might be functional adaptations rather than merely outdated evolutionary remnants.
  • Summary: The conversation explored the mystery of why evolution bequeathed humans a brain capable of self-deception. While many biases are explained as outdated evolutionary traits, Vedantam suggests some errors might play a functional role in our current success and well-being. If these biases were eliminated, humans might actually find themselves set back.
Functional Filtering of Reality

(00:10:06)
  • Key Takeaway: The brain filters out the vast majority of sensory input to function efficiently, a process akin to profound self-deception.
  • Summary: The human eye takes in about a billion bits of information, but the brain filters this down to about 40 bits for processing at any moment. This filtering, which bears little resemblance to raw reality, allows the brain to function frugally and attend to necessary tasks. Similarly, positive illusions about romantic partners lead to happier and more stable relationships.
Parental Delusion as Evolutionary Aid

(00:12:23)
  • Key Takeaway: The belief that one’s child is the most special in the universe is a useful delusion necessary for enduring the challenges of parenting.
  • Summary: Parents often hold the delusion that their child is uniquely incredible, which is necessary because parenting is inherently challenging, time-consuming, and frustrating. Without this vast self-deception, parents might conclude their children are more curse than blessing, failing in their evolutionary duty to raise them securely. The survival of humanity testifies to the value of parental self-deception.
Double-Edged Sword of Self-Deception

(00:15:14)
  • Key Takeaway: Self-deception is a double-edged sword, simultaneously functional in maintaining relationships (e.g., positive partner illusions) and pernicious in abusive situations.
  • Summary: In intimate relationships, believing a partner is the ‘most beautiful’ can be useful, but self-deceptions that rationalize abuse are profoundly harmful. The Mahabharata illustrates how parental love can blind a king to his son’s evil, leading to ruin, showing how delusion can cause ethical harm. Ultimately, the utility of self-deception must be judged by the outcomes it produces.
Mortality Denial as Self-Soothing

(00:17:39)
  • Key Takeaway: The widespread self-deception that one will not face impending death serves to prevent paralyzing despair and allows functional living.
  • Summary: The belief that one will not be the next to die, despite witnessing aging and death constantly, is a self-deception that keeps people focused and hopeful. Constantly carrying the thought of impending doom would be debilitating and weigh down daily interactions. Spiritual practices like Memento Mori offer a middle path by using mortality to vivify the present moment, leading to gratitude.
Judging Useful vs. Harmful Delusions

(00:21:03)
  • Key Takeaway: The utility of a delusion is best determined by observing its real-world outcomes, such as whether it fosters kindness or exploitation.
  • Summary: There is no simple line demarcating useful from harmful delusion; outcomes must be observed. Delusions leading to kinder, better, and more empathetic behavior are considered functional, while those causing exploitation or harm are dangerous. While one might try to challenge harmful thoughts (like racial bias), the decision to allow a useful one (like believing one’s child is special) is based on its positive result.
Compassion Through Understanding Delusion’s Function

(00:26:37)
  • Key Takeaway: Understanding that self-deception soothes psychological needs fosters compassion for oneself and for those holding views one disagrees with.
  • Summary: Vedantam’s research led him to be more compassionate toward his own mind, such as his self-soothing belief that COVID-19 ’liberation’ was always four weeks away. This insight extends to others: when encountering outlandish beliefs, one should ask what psychological purpose the delusion serves rather than simply arguing with facts. Effective change requires addressing the underlying psychological need.
Limits of Empathy in Extreme Cases

(00:38:04)
  • Key Takeaway: Empathy for delusions has limits when immediate physical danger is present, but psychological intervention is necessary when delusions are widely shared.
  • Summary: In situations of immediate threat, like an armed person at the door or the storming of the U.S. Capitol, immediate protective action (calling police) supersedes psychological exploration. However, when a dangerous belief is shared by large numbers, like vaccine hesitancy, psychological explanations and interventions become necessary. These interventions can leverage self-deception, such as framing vaccination as a social norm or introducing artificial scarcity.
Naive Realism and Judgment
Copied to clipboard!
(00:41:30)
  • Key Takeaway: Naive realism causes people to assume their perception is the objective norm, leading to judgment against those who see the world differently.
  • Summary: Naive realism is the psychological principle that one’s view of reality must be the correct view everyone else should share. This is illustrated by the observation that drivers going faster than you are maniacs, and those going slower are idiots. This tendency prevents empathy, as seen when Vedantam initially judged members of the Church of Love as being ‘wrong’ for believing the letters.
Self-Deception as a Form of Privilege
Copied to clipboard!
(00:44:08)
  • Key Takeaway: The ability to forgo self-deception is often a privilege afforded by a life currently free of severe vulnerability or crisis.
  • Summary: When facing a life-threatening situation, like Vedantam’s emergency retinal detachment, one immediately places absolute trust in an authority figure without time for rational evaluation. This vulnerability proves that self-deception (or faith in others) is often a necessity when life is not going well. Those whose lives are currently stable and healthy have the luxury of not needing the comforting self-deceptions others rely on.
Hope as Essential Self-Deception

(00:47:51)
  • Key Takeaway: Hope is one of the most important functions of self-deception, counteracting the dispiriting realization of human insignificance in the vast universe.
  • Summary: Human lives are cosmically inconsequential, easily forgotten specks in the universe, a realization that is inherently dispiriting. To function, humans across all cultures create beliefs, rituals, and self-deceptions to give their lives meaning and purpose. Providing hope is a primary way the mind deceives itself to avoid nihilism and paralysis.
Depression: Clear Sight or Delusional Pessimism?

(00:51:56)
  • Key Takeaway: Some research suggests that depression involves seeing reality more clearly than mentally healthy individuals, whose functioning relies on delusional optimism.
  • Summary: Historically, mental illness was seen as detachment from reality, but depression patients sometimes demonstrate clearer perception than healthy individuals in experimental settings. This suggests that being mentally healthy might require a delusional sense of optimism or hopefulness to function daily. Seeing reality exactly as it is might be accurate but dysfunctional for navigating life’s challenges.
Self as Ship of Theseus Metaphor

(00:57:43)
  • Key Takeaway: The continuous physical and psychological change inherent in life suggests that the consistent sense of ‘self’ is itself a functional self-deception.
  • Summary: Drawing on the Ship of Theseus paradox, Vedantam notes that both the body’s material components and the mind’s beliefs constantly change over time. The belief that one is the same person across decades—serving that future self—is a functional self-deception. This concept aligns with Buddhist ideas that the persistent sense of self may be an illusion.
Self as Illusion Debate

(01:00:18)
  • Key Takeaway: The continuity of the self across a lifespan might be a profound, yet functional, self-deception.
  • Summary: The discussion questions whether the consistent sense of self experienced over time is an illusion, similar to Buddhist concepts. If one believes they are the same person across childhood and old age, actions are taken to serve that future self. However, this belief might be a functional self-deception, even if profoundly disturbing to consider.
Evolutionary Function of Self

(01:04:28)
  • Key Takeaway: Emotions like fear and love are understood as functional inventions of natural selection, suggesting the sense of self is also evolutionarily useful.
  • Summary: If the brain is a product of evolution, its contents, like fear or love, exist because they are functional for survival. The sense of self is likely invented by natural selection for similar utility. The challenge lies in whether minds can now transcend these evolutionary inventions for a greater good.
Two Levels of Reality

(01:06:32)
  • Key Takeaway: Buddhist practice suggests evolving beyond the self by distinguishing between conventional reality and ultimate reality.
  • Summary: Buddhists often describe reality in two tiers: conventional reality (operating as Dan or Shankar in daily life) and ultimate reality. In ultimate reality, while one is present, the entity asking the question of ‘who’ cannot be found, suggesting the self is an illusion at that deeper level.
Machine Probing Itself

(01:07:44)
  • Key Takeaway: Using the self-deceiving brain machine to pierce the veil of self-deception presents a massive, inherent philosophical and practical problem.
  • Summary: If the brain is designed to produce self-deceptions (like the illusion of self), using that same machine to uncover those deceptions is inherently problematic. Meditation practice is described as riding this flawed vehicle against the current of forgetting and denial, which is why it is so difficult.
Linguistic Trick for Detachment
Copied to clipboard!
(01:10:46)
  • Key Takeaway: A linguistic shift from “I am angry” to “There is anger” helps create psychological distance from powerful emotions.
  • Summary: A meditation teacher suggests changing language to frame emotions as external phenomena, such as saying “There is desire” instead of “I am hungry.” Claiming anger as one’s own is described as a misappropriation of public property, and recognizing emotions as transient events is liberating.
Psychotherapy and Observation

(01:12:18)
  • Key Takeaway: Standing apart from one’s experiences, similar to psychotherapy techniques, is psychologically wise even if challenging the core self is avoided.
  • Summary: The wisdom of standing apart from experiences is central to psychotherapy, where a therapist helps a patient listen back to themselves. Recording one’s feelings and listening back allows one to become an observer, slightly detached from the immediate experiencer.

(01:13:26)
  • Key Takeaway: Shankar Vedantam’s new book, Useful Delusions, encourages greater compassion by understanding the mind’s self-deceptions.
  • Summary: The book Useful Delusions: The Power and Paradox of the Self-Deceiving Brain is available everywhere and aims to help readers approach difficult conversations with more effectiveness and compassion. The book is an outgrowth of his previous work, The Hidden Brain, which inspired the Hidden Brain podcast and radio show.
