Introduction
I believe personality is built, not born. Children pick up their emotions and beliefs through how their parents treat them. These get stored in the brain and keep running throughout life. As adults, they shape most of how we think, feel, and act — usually without us knowing it.
Here's how that works.
Why Emotions Matter So Much
Emotions touch every part of life. They affect the body, shape how we think, and drive what we do. Here are some examples:
Health: Emotions affect the heart, lungs, brain, and every other organ in the body.
Thinking and memory: Strong emotions make it harder to focus and learn.
Intelligence: When emotions are in the way, people think less clearly and solve problems less easily.
Decisions: Fear makes us cautious. Anger can make us act without thinking.
Creativity: Joy and curiosity open the mind. Anxiety closes it.
Addiction: People use substances to escape painful feelings.
Relationships: Emotions shape how much we trust others, how close we get, and how we handle conflict.
Emotions aren't just feelings. They are forces that shape who we are.
How Children First Pick Up Emotions
Children pick up emotions in two ways.
1. Copying (Mimicry):
Children copy what they see.
If a child sees a parent get angry at a pet, the child learns to feel angry at the pet too.
If a parent treats a pet kindly, the child learns kindness.
If a parent seems emotionally flat or checked out, the child copies that too.
Children also copy during direct interaction:
A parent smiles → the child smiles back.
A parent seems sad while comforting a child → the child picks up that sadness.
2. Opposite Reactions
Sometimes children don't copy — they react with the opposite emotion. To explain this, I divide emotions into two groups.
Category 1 emotions are active and energizing. They push outward. Think: anger, frustration, irritation, impatience, disapproval. Scolding, criticizing, and punishing are usually charged with Category 1 emotion.
Category 2 emotions are the opposite — withdrawing, shutting down, going inward. Think: distant, unresponsive, checked out, indifferent, emotionally flat.
Here's what happens when these emotions are directed at a child:
Category 1 aimed at a child → the child feels fear. Example: A parent scolds a child → the child feels afraid.
Category 2 aimed at a child → the child feels Category 1 emotion (anger, frustration, activation). Example: A parent ignores a child showing them a drawing → the child feels irritated and pushes harder for attention.
Both feel like a threat. Category 1 feels like an attack. Category 2 feels like being abandoned.
How This Shapes Personality: Baseline Emotions
When emotions get triggered often enough in childhood, they become permanent. I call these baseline emotions — emotions that are always running in the background, even when nothing is happening.
A few key things about baseline emotions:
They come from the emotional interactions described above.
The more intense and frequent those interactions were, the stronger the baseline emotion.
They run mostly outside our awareness. We don't usually recognize them as emotions — they just feel like "how we are."
They are what most people call temperament.
Copying makes children emotionally similar to their parents. Being on the receiving end of Category 1 or 2 emotions makes children emotionally different from their parents.
If a parent dies or is absent for a long time, the child's brain reads that as the parent showing Category 2 emotion, which they mimic. Over time, that emotional flatness becomes part of the child's baseline.
How Older Children React
Older children react differently because their earlier baseline emotions mix with what's happening now.
A child with a strong Category 2 baseline will react less when ignored — they've already partly checked out.
A child with a strong Category 1 baseline will react more intensely when ignored — the anger is already primed and fires faster.
How Children Pick Up Beliefs
Children also form beliefs early in life:
They generally believe whatever a parent tells them.
Positive treatment from parents → positive beliefs about the parent and themselves.
Category 1 directed at them (scolding, punishing) → two conflicting beliefs: "I did nothing wrong" and "Maybe I'm a bad person."
Category 2 directed at them (ignoring, withdrawing) → two conflicting beliefs: "Something is wrong with me" and "Something is wrong with you."
Outside experiences also shape beliefs — a bad experience at school, a good experience with someone from a different background, and so on.
Schemas: How the Brain Stores All of This
As children grow, the brain organizes all of these memories, emotions, and beliefs into structures called schemas.
Think of a schema as a folder. Every time something happens, the brain files it away — what happened, who was involved, what it felt like, how it ended. Over time, these folders get bigger and more organized. When a new situation comes up, the brain quickly searches its folders, finds the closest match, and uses it to interpret what's happening right now.
This happens instantly and automatically — we don't notice it.
A few important things about schemas:
They generalize. What a child learned about parents often gets applied to teachers, bosses, and other authority figures later in life.
They hold contradictions. A schema can store "people help me when I ask" and "no one really helps." Whichever one matches the current situation becomes active.
They produce baseline emotions continuously. Because schemas never stop running, they never stop producing the emotions built into them.
How Schemas Run Adult Life
In adulthood, schemas quietly run in the background and shape almost everything.
When we face a situation, the brain matches it to childhood memories and interprets it through that old lens.
The rational brain doesn't override this — it actually defends it. It ignores facts that don't fit the old beliefs and highlights facts that do. This is why people are drawn to ideas that match what they already believe, even when the evidence is thin.
Emotional reactions are driven by schemas. When a reaction feels bigger than the situation deserves, it's usually because the schema being triggered is attached to a strong childhood emotion.
Adult schemas don't change on their own. What looks like change is usually just a different part of the same schema becoming active. People with a wider range of childhood experiences have more parts to draw from, so they can seem to change more.
What This Explains
Intelligence: Baseline emotions directly affect the brain's ability to focus, absorb, and process information. This accounts for most of the differences we see in how people think and learn.
Mental health disorders: Every symptom of a psychiatric disorder — emotional, physical, or mental — can be traced back to baseline emotions and childhood beliefs.
Emotional symptoms (like depression or anxiety) → caused by baseline emotions.
Physical symptoms (like low energy or sleep problems) → also caused by baseline emotions.
Mental symptoms (like "everyone hates me") → caused by beliefs formed in childhood.
Medical problems: Emotion has a direct effect on the body. It can cause physical illness and affect how well the body heals.
Summary
Childhood is the foundation for everything that follows. The emotions and beliefs we pick up early in life shape how we think, feel, and act as adults — in ways most of us never fully see.
