Useful Delusions

The concept that self-deception, while potentially harmful, can paradoxically serve a functional purpose in our lives. It can enhance happiness in relationships, aid in parenting, and help individuals cope with difficult realities by filtering information or fostering optimism.

Naive Realism

A psychological principle where individuals assume their perception of the world is the objective reality and the only correct way to see it. This bias often leads to judgment and a lack of empathy for others who hold different views.

Delusional Optimism

The idea that a degree of positive self-deception or hopefulness is essential for mental health and functional living. It allows individuals to navigate daily challenges, maintain relationships, and pursue goals without being overwhelmed by harsh realities.

Illusion of Self

A Buddhist concept suggesting that the perceived, consistent 'self' or 'I' is not a fixed entity but a moment-to-moment construction of the mind. Recognizing this illusion, rather than clinging to a solid self, can be a path to liberation from greed and hatred.

?
Can self-deception ever be beneficial?

Yes, paradoxically, self-deception can play a vital role in success, well-being, and maintaining relationships, even nations, by filtering reality, fostering positive illusions, and providing psychological comfort.

?
Why do humans have a robust capacity for self-deception?

Evolution has likely bequeathed us this capacity because certain biases and errors, like filtering sensory information or having positive illusions about loved ones, serve a functional role, allowing us to operate efficiently and survive.

?
How can we distinguish between useful and harmful delusions?

The utility of a delusion is best judged by its outcomes; useful delusions lead to kindness, empathy, and compassion, while dangerous ones cause exploitation, harm, or unethical behavior. It's difficult for an individual to know in the moment.

?
How should one approach someone with a dangerous delusion, like vaccine hesitancy?

Instead of presenting facts or arguing, one should start with empathy and compassion, asking about their fears and concerns. Understanding the psychological purpose the delusion serves can be more effective than simply disproving it with data.

?
What is 'naive realism' and how does it affect our interactions?

Naive realism is the belief that our perception of reality is the correct and only way to see the world. This often leads to judging others as 'wrong' or 'idiots' when their views differ, hindering empathy and understanding.

?
Is depression a form of clear-sightedness or delusional pessimism?

Research suggests that depressed individuals sometimes see the world more clearly than 'mentally healthy' people, challenging the idea that mental health always involves accurate reality perception. It implies that mental health might involve a degree of 'delusional optimism.'

?
What is the Buddhist perspective on the 'self'?

In Buddhism, the sense of a fixed, core 'self' is considered a moment-to-moment construction. Uprooting this delusion, while challenging, is seen as liberating, reducing the wellspring of greed and hatred.

1. Combat Delusions with Empathy

Start with empathy and compassion when trying to disabuse people of dangerous self-deceptions, as this approach is more powerful and effective than argument.

2. Address Delusion’s Psychological Purpose

To effectively challenge someone’s delusion, understand the underlying psychological purpose it serves for them and explore alternative ways to meet that psychological need, rather than just presenting facts.

3. Assume Good Intent, Empathize

Approach conversations with those holding differing views by assuming they are trying to do what’s best for themselves and their loved ones, empathize with their underlying motivations, and then gently explain your different approach.

4. Inquire About Underlying Fears

When someone holds a belief you disagree with, especially on sensitive topics like vaccine hesitancy, ask them directly about their specific fears and worries to understand their perspective, instead of immediately countering with data.

5. Validate Fears, Share Experience

When addressing someone’s fears (e.g., vaccine hesitancy), validate their concerns as justified and stemming from good intentions, then share your own similar thought process and conclusion, rather than belittling them or just presenting facts.

6. Recognize Naive Realism

Understand that your perception of reality is not necessarily the only or correct way to see the world, and that others may genuinely see things differently, which can foster empathy.

7. Question Beliefs’ Deeper Role

Instead of dismissing others’ beliefs as irrational or illogical, ask deeper questions about why people turn to those beliefs and what psychological role they serve for them.

8. Cultivate Self and Other Compassion

Understanding the role of self-deception can lead to greater compassion for your own mind’s workings and for the minds of others, especially when they hold beliefs you disagree with.

9. Be Easier on Self/Others

Adopt a more compassionate stance towards yourself and others regarding self-deception, understanding that it often serves a functional purpose, especially in times of vulnerability or crisis.

10. Recognize Privilege in Rationality

Understand that foregoing self-deception can be a form of privilege, as people in difficult circumstances often rely on ‘wildest self-deceptions’ for hope and coping, making it important to respond with less judgment.

11. Cultivate Positive Partner Illusions

Believe your romantic partner possesses very positive traits (e.g., handsome, kind, generous), even if not entirely true, as these positive illusions can lead to a happier and more stable relationship.

12. Embrace Parental Delusion

Allow yourself the self-deception that your child is the most special, as this ‘useful delusion’ helps parents endure the challenges of raising children and fosters a secure upbringing.

13. Cultivate Delusional Optimism

Recognize that a ‘delusional sense of optimism’ can be functional and necessary to navigate daily life, motivating you to be productive, a good parent, partner, and community member, even if it means not seeing reality ‘clearly’.

14. Soothe Anxiety with Short-Term Delusion

During difficult, open-ended challenges, create a short-term, self-deceiving timeline (e.g., ’liberation is a month away’) to soothe anxieties and make the situation more bearable.

15. Break Down Monumental Challenges

When facing monumental challenges or despair, break them into bite-sized portions (e.g., ‘one day at a time’) to make them easier to navigate and survive.

16. Highlight Positive Social Norms

To encourage a desired behavior (like vaccination), emphasize the number of people who are adopting it, rather than focusing on those who are not, as people tend to follow social norms.

17. Create Artificial Scarcity (for vaccines)

To encourage vaccine uptake, create a sense of artificial scarcity by personalizing doses and communicating that an individual’s specific dose will be given to someone else if not claimed, leveraging the fear of loss.

18. Use Psychological Interventions for Widespread Beliefs

For beliefs shared by large numbers of people (e.g., dangerous mass delusions), psychological explanations and interventions are necessary, as direct confrontation or force is not feasible.

19. Reframe Emotions as Phenomena

When experiencing powerful emotions or desires, reframe them in your mind from ‘I am angry’ to ’there is anger,’ to see them as transient phenomena rather than core aspects of your identity.

20. Practice Emotional Detachment

Regularly remind yourself that you are not your emotions, they are transient experiences happening to you, and practice patience with them to see their true nature.

21. Record and Observe Feelings

To gain perspective on your emotions, record what you’re feeling onto a voice recorder and listen back, allowing you to observe your experiences from a slight distance rather than being fully immersed in them.

22. Contemplate Mortality Mindfully

Allow yourself a fleeting thought about your own mortality to vivify the present moment, fostering gratitude and a healthy sense of urgency, rather than agonizing or denying it.

23. Enhance Interactions with Mortality

Remind yourself that any interaction or meeting might be the last, which can make you more attentive, mindful, compassionate, forgiving, and empathetic towards others.

24. Regular Mortality Contemplation

For meditators or practitioners, it is possible to contemplate mortality on a regular, consistent basis without feeling overwhelmed, potentially leading to deeper insights.

25. Adopt Empathy and Compassion

Embrace empathy and compassion as a core mandate in your life, as it leads to greater understanding and sympathy for the world, rather than anger or contempt.

Self-deception can indeed do great harm to us, but it turns out paradoxically that it can sometimes do great good for us.

Shankar Vedantam

If we were to perform a mere cost-benefit analysis about the value of our children, some of us might conclude that our children are not quite worth it, that in fact, our children are more curse than blessing.

Shankar Vedantam

We see death and dying around us all the time, but all of us in our heart of hearts believe that it's not going to come for us or that we will not be the next person to die.

Shankar Vedantam

Delusions, when they occur, are often playing a psychologically functional purpose. They might be wrong, they might be inaccurate, they might even be harmful, but they're playing some kind of role that soothes or answers a psychological question that we're experiencing.

Shankar Vedantam

Foregoing self-deception, ironically might be a form of privilege.

Shankar Vedantam

Part of being mentally healthy might involve not seeing the world clearly, but seeing the world through a delusional sense of optimism, through a delusional hopefulness.

Shankar Vedantam

To claim anger is yours as a misappropriation of public property.

Approaching People with Dangerous Delusions (e.g., Vaccine Hesitancy)

Shankar Vedantam
  1. Start with empathy and compassion, rather than argument or providing evidence.
  2. Ask the person what is worrying or bothering them, seeking to understand their fears.
  3. Acknowledge that their fears may stem from a good place (e.g., love for their children or family).
  4. Explain how you might approach the question differently, without belittling their concerns.
  5. For large-scale interventions, recruit the 'self-deceiving brain' by communicating social norms (e.g., most people are vaccinated) or creating artificial scarcity (e.g., 'this dose is for you, but you can lose it').
