Temperament and Character: Understanding the Foundations of Your Personality
"It's my character, I won't change." How often do we hear this sentence? It actually mixes two notions that psychology carefully distinguishes: temperament and character. One is largely innate, the other is shaped. Knowing which is which changes everything in the way we understand and grow.
In the article that follows, I explore personality types. If you recognise yourself in this theme, I designed a 16 personality types test that helps you take stock of your personality profile. It comes with a guide to extend your reflection beyond the results.
I am Gildas Garrec, a CBT psychotherapist. In my work, I often see people believe themselves prisoners of an immutable "nature." The truth is more nuanced and much more encouraging: one part of you is stable, another is in constant motion. This article helps you distinguish the two and spot your own dimensions.

Temperament: the innate part
Temperament is the biological basis of personality. It is present very early — it can already be observed in infants — and remains relatively stable throughout life. It describes your spontaneous way of reacting: emotional intensity, energy level, rhythm, reaction to novelty, natural sociability, impulsivity.
The pioneering work of Thomas and Chess, in the 1970s, showed that babies present distinct profiles from birth ("easy," "difficult," "slow to warm up"). This foundation does not disappear: an adult who is rather cautious and reserved often already was as a child.
Character: the constructed part
Character, on the other hand, is forged over time: through education, culture, formative experiences, relationships, and — above all — repeated choices. It is the most shapeable dimension of personality. Where temperament says "how I react spontaneously," character says "who I decide to become": my values, my ability to cooperate, to direct myself, to give meaning.
Psychiatrist Robert Cloninger formalized this distinction in an influential model: four dimensions of temperament (novelty seeking, harm avoidance, reward dependence, persistence) and three dimensions of character (self-directedness, cooperativeness, self-transcendence).

Beyond the models, a few concrete dimensions structure most profiles.
- Emotionality: the intensity and speed with which your emotions activate. Strong emotionality is not a flaw — it is also a richness of sensitivity.
- Energy and rhythm: your spontaneous activity level, your need for stimulation or calm.
- Sociability: your natural tendency to seek or avoid contact, on the introversion-extraversion continuum.
- Impulsivity: your relationship with immediate action versus reflection. It can be a source of spontaneity as well as difficulty.
- Harm avoidance: your level of caution, anticipation of risks, sometimes anxiety.
What this concretely changes
Understanding your temperament is not a label that confines you — it is a map that frees you. If you know that your harm avoidance is high, you stop blaming yourself for your caution: instead, you learn to gauge your exposure to the situations that worry you. If your impulsivity is strong, you set up safeguards instead of feeling guilty afterward.
In CBT, we talk about working with your temperament rather than against it. You do not erase a nature; on top of it, you develop a more flexible character, more aligned with your values. This is exactly what Cloninger's "self-directedness" covers: the ability to steer your life regardless of your temperamental starting point.
Identifying your profile
Putting words to your temperament and character is a precious step of self-knowledge — useful for understanding yourself better, communicating better, and choosing environments that suit you.
🧭 Discover your dimensions in a few minutes. The temperament and character test begins for free (the first 60 questions are offered), then provides a detailed PDF report: emotionality, energy, sociability, impulsivity, and ways to work with your nature. An insight, never a verdict.
What to remember
Your personality rests on two levels: an innate and stable temperament, and a constructed and evolving character. You will not change your biological foundation overnight — but you can, all your life, grow the part of you that chooses. To know yourself is to stop fighting against yourself and to start steering yourself.

In short: Temperament refers to the innate, biological, and early part of our personality — our spontaneous way of reacting to emotions, novelty, and relationships. Character, on the other hand, is built over the course of life, experiences, and choices: it is the shapeable part. Scientific models (Thomas & Chess for child temperament, Cloninger for his seven-dimension model) distinguish dimensions such as novelty seeking, harm avoidance, reward dependence, and persistence. Understanding your temperament is not a cage: on the contrary, it allows you to work with your nature rather than against it, and to develop a freer character. Personality is neither completely fixed nor infinitely malleable — and that is good news.
