How Childhood Wires Your Attachment Style — and How to Rewire It
Attachment styles are subconscious rulebooks for love wired in childhood — and roughly half of us carry an insecure one. Thais Gibson breaks down the four styles and shares a 21-day, evidence-based practice to rewire core wounds like the fear of abandonment. She and Dr. Gundry close with a striking exchange on the gut microbiome as a driver of these very patterns.
Overview
Personal development educator Thais Gibson joins Dr. Steven Gundry to explain why our adult relationship patterns are set long before we choose our partners. Attachment styles, she explains, are subconscious rulebooks for giving and receiving love, conditioned in childhood through repetition and emotion — and since the subconscious drives 95–97% of our thoughts and actions, willpower alone cannot override them.
Roughly half the population is securely attached; the rest split among anxious, dismissive avoidant and fearful avoidant styles, each shaped by a distinct pattern of inconsistency, emotional neglect or chaos. Gibson walks through how stored childhood wounds get projected onto adult life like a bear once seen in the woods, and how beliefs cascade into thoughts, stress emotions and behavior.
The hopeful core of the conversation is neuroplasticity: a belief-reprogramming practice built on ten evidence-based memories, repeated in a suggestible state for 21 days, which she reports has helped rewire core wounds for tens of thousands of students. The pair also connect attachment to physical health — from nervous-system dysregulation to late-night cravings, which Gibson reframes as subconscious attempts to meet needs for comfort and connection. The episode closes with Gundry's provocative thesis that the gut microbiome effectively is the subconscious mind, with distinct microbial signatures mapped to maladaptive behaviors.
Key quotes
5Your attachment style is basically the subconscious set of rules that you've been conditioned with about how to give and receive love.
Our conscious mind cannot out-will or overpower our subconscious mind.
It is always more work not to do the work.
You're not starving for your M&Ms, you're starving for connection, safety and comfort.
My personal feeling is the microbiome is our subconscious mind.
Key ideas
9The subconscious rulebook for love
An attachment style is a conditioned set of rules for giving and receiving love, rooted in research by John Bowlby and Mary Ainsworth. Two partners with different styles are like players following Scrabble rules versus Monopoly rules — even with good intentions, the game breaks down.
The conscious mind is only 3–5% of the story
The conscious mind governs roughly 3–5% of beliefs, thoughts, emotions and actions, while the subconscious and unconscious drive 95–97%. That is why resolutions to change relationship patterns keep collapsing back into old dynamics.
The bear in the woods: negativity bias
The mind stores negative experiences more strongly than positive ones and projects stored threats outward. A childhood abandonment wound can turn a ten-minute unanswered text into a full alarm response in adulthood.
BTEA: beliefs, thoughts, emotions, actions
Core beliefs branch into thought patterns, thoughts trigger stress emotions like cortisol and norepinephrine responses, and actions ride those emotional states. Even self-described rational people decide emotionally first and rationalize afterward.
Secure attachment — the fortunate 50%
About half the population grows up with attuned, consistent parents who model healthy communication, and they report the longest and most fulfilling relationships. What matters is not a perfect childhood but the ratio of healthy to unhealthy experiences.
Anxious attachment grows from inconsistency
Real or perceived abandonment — love that appears and disappears — conditions a deep fear of being left, disliked or excluded. Anxious adults seek immediate conflict resolution, people-please, blur boundaries, and tie self-worth to external approval, which chronically dysregulates the nervous system.
Dismissive avoidance grows from emotional neglect
Orderly households where emotions are dismissed teach children to repress their vulnerable side. As adults they create distance when things get serious, take criticism as proof of being defective, and struggle with the vulnerability healthy relationships require.
Fearful avoidance grows from chaos
Big-T trauma such as an addicted or abusive parent wires opposing associations: love is wonderful and love is dangerous. The result is hypervigilance to micro-expressions and a hot-and-cold pattern of pulling people close and pushing them away — Gibson's own former style.
Rewiring through repetition, emotion and imagery
No one is born with an attachment style, and neuroplasticity means it can be reconditioned. Belief reprogramming pairs a core wound with its opposite, backs it with ten real memories as evidence, and repeats the practice for 21 days while the brain is in a suggestible state.
Practical takeaways
6- 1
Understand the patterns instead of assigning blame 4:30
Parents pass down the conditioning they received, and conditioning continues throughout life. Focus on identifying your acquired patterns, not on blaming anyone for them.
- 2
Swap affirmations for evidence 31:30
Affirmations are the conscious mind talking to itself. Instead, list ten recent, true memories that prove the opposite of your core wound — real events carry the emotion and imagery the subconscious actually responds to.
- 3
Practice 2–5 minutes a day in a suggestible state 34:00
Record your ten memories and listen back daily for 21 days, ideally in the first hour after waking, the last hour before sleep, or after meditation, breathwork or hard exercise, when alpha and theta brainwaves make the mind sponge-like.
- 4
Regulate before you reach for the snack 39:30
Cravings usually start in a dysregulated, fight-or-flight state. A short somatic exercise that shifts you toward the parasympathetic state dramatically reduces the craving — then ask what need the food was standing in for.
- 5
Love people the way they need to be loved 37:00
Each attachment style receives love differently — one partner may need validation while the other needs respect and autonomy. Learn your partner's needs instead of defaulting to your own.
- 6
One person can start the change 42:30
When one partner rewires triggers, regulates their nervous system and communicates needs clearly, the relationship usually improves immediately — as long as the other is at least willing to participate in healthier communication.
Topics & chapters
12What is an attachment style?
Gibson defines attachment styles as subconscious rules for love, tracing the research back to John Bowlby and Mary Ainsworth and the board-game analogy for mismatched rules.
The 95% you don't control
The conscious mind holds only 3–5% of our beliefs and actions; the subconscious warehouse of conditioning holds the rest, which is why willpower alone fails.
Negativity bias and the bear in the woods
Stored threats from childhood are projected onto adult relationships, from abandonment panic over an unanswered text to pushing people away to protect freedom.
From belief to behavior: the BTEA chain
Beliefs branch into thoughts, thoughts ignite stress emotions and nervous-system shifts, and actions follow emotional states — mostly beneath conscious awareness.
Secure attachment: the gold standard
Around 50% of people grow up with attuned, consistent parenting and report the longest, most fulfilling relationships. The healthy-to-unhealthy ratio matters more than perfection.
The anxious attachment style
Inconsistency or abandonment in childhood breeds fear of being left, urgency to resolve conflict immediately, people-pleasing and self-worth tied to approval.
The dismissive avoidant style
Structured but emotionally unavailable homes teach children to repress vulnerability; as adults they need distance, minimize needs and can sabotage closeness.
The fearful avoidant style
Chronic big-T trauma wires love as both wonderful and dangerous, producing hypervigilance and hot-and-cold relationships. Gibson shares that this was her own style.
Hope: the five pillars and belief reprogramming
Rewiring core wounds, meeting needs, regulating the nervous system, communication and boundaries — starting with a 21-day memory-based reprogramming exercise.
Making it work in a busy life
The practice takes 2–5 minutes a day, and being less triggered, more fulfilled and more regulated ends up giving busy parents time back.
Cravings, comfort and somatic processing
Unhealthy habits are subconscious strategies to meet needs — food is wired to connection and safety from infancy. Regulating the nervous system diminishes cravings.
Is the microbiome the subconscious mind?
Gundry answers Gibson's audience question: maladaptive behaviors carry distinct microbiome signatures, and changing the bacteria — or the thoughts — changes the pattern.
