Attachment Styles

Categories (secure, anxious avoidant, anxious ambivalent, disorganized) describing how toddlers react to caregiver separation and return. These styles are strongly predictive of an individual's romantic attachment patterns later in life, though they are malleable.

Autonomic Arousal (Seesaw Analogy)

Refers to the state of the autonomic nervous system, which can range from alert to calm. The 'hinge' of this seesaw represents one's autonomic tone, indicating how readily their physiological state can shift between these extremes.

Empathic Matching

The process where one individual's autonomic nervous system tends to mimic or synchronize with another's. This autonomic coordination, involving brain areas like the insula and prefrontal cortex, is crucial for establishing and maintaining emotional bonds.

Positive Delusions

Beliefs that only a specific person can make one feel a certain way. These beliefs are identified as a critical factor for the stability and longevity of long-term relationships.

The Four Horsemen of Relationships

Four behaviors identified by the Gottmans (criticism, defensiveness, stonewalling, and contempt) that are powerful predictors of relationship failure. Contempt is considered the most potent and destructive of these.

Self-Expansion

A metric involving one's perception of self as seen through the relationship to another. It describes how being in a relationship can make an individual feel better about themselves and more capable, contributing to healthy interdependence.

?
What are the four attachment styles identified in children?

The four attachment styles are secure, anxious avoidant (insecurely attached), anxious ambivalent/resistant (insecure), and disorganized/disoriented, categorized by how toddlers react to a caregiver's presence and absence.

?
How do childhood attachment styles influence adult romantic relationships?

Childhood attachment styles are strongly predictive of an individual's attachment style in romantic partnerships later in life, although these patterns can be modified over time through self-awareness and understanding.

?
What is the role of the autonomic nervous system in desire, love, and attachment?

The autonomic nervous system, conceptualized as a seesaw of arousal, is a key component, with autonomic coordination (the synchronization of physiological states between individuals) being a hallmark feature of desire, love, and attachment.

?
What brain circuits are crucial for establishing and maintaining emotional bonds?

Multiple brain circuits are involved, including those for the autonomic nervous system, empathy (involving the insula and prefrontal cortex for autonomic matching), and positive delusions, alongside the dopamine system for motivation and pursuit.

?
What behaviors are strong predictors of relationship failure?

The 'four horsemen of relationships' identified by the Gottmans—criticism, defensiveness, stonewalling, and contempt—are powerful predictors of relationship breakdown, with contempt being the most destructive.

?
Can a structured set of questions facilitate falling in love?

A study involving 36 progressively deeper questions has shown that people who engage in this exchange report feeling a strong sense of knowing and attachment, or even love, for the other person, possibly due to the establishment of a personal narrative and autonomic coordination.

?
How does self-expansion in a relationship affect one's perception of other potential partners?

When individuals experience high self-expansion from their significant other (e.g., through praise that highlights their importance to the relationship), brain areas associated with assessing the attractiveness of others show lower activation, making alternative partners appear less attractive.

?
What is the combined role of testosterone and estrogen in libido?

Both testosterone and estrogen are essential for libido and sex drive in both males and females; it's a coordinated interaction between these hormones, and very low estrogen levels can significantly impair libido.

?
Does simply increasing dopamine always lead to higher libido?

While some level of dopamine increase is necessary for libido, excessively high dopamine levels can lead to such intense autonomic arousal that individuals may desire sexual activity but struggle to engage the parasympathetic system required for physical arousal.

1. Cultivate Stable Self-Representation

Develop a stable internal representation of yourself and a stable autonomic nervous system, as this foundational self-stability is crucial for forming and maintaining stable romantic partnerships.

2. Recognize Malleability of Attachment

Understand that early-life attachment styles are not fixed and can shift over time, as merely knowing they exist and are malleable is a powerful way to change them.

3. Assess Your Attachment Style

Reflect on whether you exhibit secure, insecure, or other attachment styles, as understanding this can be a foundational step in addressing desire, love, and attachment.

4. Cultivate Autonomic Self-Regulation

Strive for healthy interdependence by being able to adjust your own autonomic nervous system and self-soothe even when your partner is absent, rather than solely relying on their presence.

5. Recognize Autonomic Self-Soothing

Become aware of your autonomic nervous system’s state, especially whether you can self-soothe and calm yourself when alone, or if you are overly dependent on another’s presence for comfort.

6. Avoid Relationship “Four Horsemen”

To maintain stable relationships, avoid criticism (especially frequent and intense), defensiveness (lack of empathy), stonewalling (emotional cutoff), and contempt, as these are strong predictors of relationship failure.

7. Offer Partner Self-Expansion Praise

If your partner benefits from self-expansion, offer praise and statements that highlight their vital role in creating an exciting, novel, and challenging relationship, as this can reduce their perception of others’ attractiveness.

8. Regulate Caregiver Autonomic State

As a primary caregiver, manage your own stress and distress, as children’s autonomic nervous systems tend to mimic yours, influencing their long-term stress and trauma responses.

9. Ask 36 Questions for Connection

Engage in a structured conversation using the ‘36 questions that lead to love,’ progressing from ordinary to deep emotional topics, as this process can foster strong feelings of attachment and intimacy by creating a shared personal narrative.

10. Utilize Comprehensive Blood Testing

Consider using Function Health for comprehensive blood testing of over 100 biomarkers to gain insights into your bodily health, detect issues like elevated mercury, and receive expert-guided recommendations for improvement.

11. Consult Doctor, Monitor Supplements

Before starting any supplements like tongat ali or maca, consult your physician and regularly monitor your blood work and subjective responses to ensure they are safe and effective for you.

12. Avoid Excessive Dopamine for Libido

Do not excessively drive up your dopamine system, as overly high arousal states can hinder the engagement of the parasympathetic nervous system needed for physical sexual arousal, despite increasing desire.

13. Consider Libido-Boosting Supplements

If appropriate and after consulting a physician, consider supplements like maca, tongat ali (longjack), and tribulus, which have peer-reviewed research supporting their ability to increase libido.

14. Take Maca for Libido

Consume 2-3 grams of maca per day, typically in the early day to avoid sleep interference, as studies show it can increase subjective reports of sexual desire in both men and women, independent of hormone changes.

15. Use Tongat Ali for Libido

Consider taking 400 mg per day of Indonesian tongat ali, as there is evidence it can increase free testosterone by lowering sex hormone binding globulin, and some reports indicate it increases libido.

16. Take Tribulus for Libido

Consider taking 6 grams (6000 mg) of tribulus root daily for 60 days, as one double-blind study showed a clear and significant increase in libido and various aspects of sexual function.

The good news is that these templates can shift over time. And one of the more powerful ways to shift those templates over time is purely by the knowledge that they exist and the understanding that those templates are malleable.

Andrew Huberman

Contempt has actually been referred to as the sulfuric acid of relationship.

Andrew Huberman

It's exactly when you're not looking for a relationship that you're going to find when you hear this stuff, right? But none of that is really grounded in any studies.
