Instinct

What is instinct and why does it continue to guide us even in the technological era?

When we talk about instinct, we often think of a mysterious, primitive, almost animal force. In reality, from a scientific perspective, instinct is one of the most refined architectures of evolution.

What are the main human instincts and how do they operate in our brain?

Scientific research identifies several major instinct systems, each with a specific adaptive function. These instincts do not operate separately but as an integrated network that constantly regulates behavior, emotions, and relationships. To understand how they shape behavior, emotions, and decisions, it is useful to examine them individually.

The main human instincts include:

Survival instinct

This is the most primitive and powerful system. It activates in the face of any perceived threat — real or symbolic — generating automatic fight, flight, or freeze reactions.

This instinct does not distinguish between a predator and a work deadline: for the emotional brain, both can represent a threat.

Attachment instinct

Belonging instinct

Pushes humans to seek the group, conform, and build collective identities. It underpins communities, cultures, ideologies, and even conflicts between groups.

How does instinct influence our emotions and daily decisions?

Every time we make a decision, even when we believe we are fully rational, instinct has already come into play. Decision neuroscience shows that emotion precedes conscious evaluation: the brain “feels” before it “thinks.”

This process occurs through several fundamental mechanisms:

• Somatic markers

These are bodily signals (tension, heartbeat, nausea, warmth, relaxation) that the brain associates with previous experiences. When facing a choice, these signals guide decisions quickly and often unconsciously. It is the body that “knows” before the mind.

• Automatic assessment of threat or benefit

Within milliseconds, the limbic system classifies a situation as safe, dangerous, desirable, or to be avoided. This instinctive evaluation shapes attention, memory, and subsequent behavior.

• Emotional cognitive shortcuts

Instinct uses quick rules based on evolutionary experience: “what is familiar is safer,” “what is rare is more valuable,” “what threatens the group is dangerous.” These shortcuts speed up decision-making but can produce biases, i.e., systematic distortions of judgment that lead to partial, simplified, or incorrect interpretations of reality, influencing decisions and behaviors without conscious awareness.

• Automatic social regulation

In every interaction, the instinctive system automatically regulates nonverbal signals that precede conscious thought: we modulate voice tone, posture, and physical distance based on perceived safety, status, and emotional closeness, while micro facial expressions communicate emotions immediately. This “silent dialogue,” processed by the limbic brain, guides trust, cooperation, and the quality of relationships.

From a psychological well-being perspective, learning to recognize these instinctive dynamics allows one to distinguish between healthy intuition and dysfunctional emotional reactions, improving decision-making and relationship quality.

Is instinct reliable or can it deceive us?

Instinct is a powerful tool, but not infallible. It was designed by evolution for a very different world. Consequently, in certain contexts, it can lead us astray.

The main limitations of instinct include:

• Evolutionary mismatch

Our instinctive brain is adapted to small prehistoric communities, not hyperconnected global cities. Reactions that were useful yesterday may be counterproductive today.

• Overestimation of danger

Instinct tends to prefer false alarms over real risks: better to be unnecessarily scared than to ignore a threat. This mechanism, however, contributes to chronic anxietyAnxiety is an emotional response characterized by feelings o... More and stress.

• Emotional biases

Prejudices, stereotypes, and irrational fears are often the result of instinctive shortcuts that simplify reality but distort it.

• Conflict with rationality

Instinct may push us toward immediate gratification, while the rational mind evaluates long-term consequences. Psychological maturity arises from integrating these two forces.

Emotional education and awareness allow one to “train” instinct, not suppress it, but make it an ally of reason.

The role of instinct in mental well-being and social relationships

A balanced relationship with one’s instinct is one of the pillars of overall well-being. When instinct is systematically ignored or repressed, the body and mind send distress signals: anxiety, psychosomatic symptoms, emotional exhaustion, and relational difficulties.

The main areas in which instinct supports well-being are:

• Psychological self-protection

• Emotional regulation

It allows recognition of authentic needs before they explode into psychological symptoms. Listening to instinct helps detect early signs of distress, stress, or frustration that indicate unmet emotional needs, preventing them from turning into anxiety, psychosomatic disorders, or relational difficulties, thus promoting a more stable mental balance.

• Building healthy bonds

Instinct unconsciously guides our relational preferences, pushing us toward people and environments that convey safety, recognition, and emotional harmony, and away from those that generate tension or threat, contributing to the formation of more stable, satisfying bonds aligned with our deep needs.

In difficult periods, instinct activates deep responses of protection, resistance, and emotional reorganization, helping the person mobilize psychological energy, reconsider priorities, find more effective ways to face challenges, and restore balance, thus fostering resilience, adaptation, and recovery of well-being.

Can we educate instinct without losing its vital force?

True psychological maturity does not consist in dominating instinct, but in learning to dialogue with it. Mindfulness practices, emotional education, psychotherapy, and self-observation develop this skill: listening to the instinctive signal, understanding its origin, and integrating it with rational evaluation.

In a society that rewards control and performance, reclaiming a healthy relationship with instinct means reconnecting with biological rhythms, deep needs, and bodily intuition. It is not regression, but conscious evolution. Instinct, in fact, is not the enemy of civilization: it is its invisible foundation.
