1s seek to live in a perfect world and work diligently to improve themselves, everyone, and everything around them. They are rational and conscientious beings who often have good self-control, so that they have restraint on their own impulses, emotions and desires. Whatever they do, they do it with the best of their abilities, based on high standards of professionalism, competence, principle, honesty and integrity. They are disciplined, organized and are often very involved workers. They are passionate about making the world better for everyone and take their work seriously. They are ready to give everything for a cause in which they believe.

Avoidance compulsion

1s seek at all costs, often unconsciously, to avoid their inner anger. Perfectionists led by morality and ethics, they have a voice in their head that criticizes everything they do wrong. They seek at all costs to avoid mistakes that would call into question their competence and reliability.

Center of attention and motivation

The attention of 1s is focused on the environment, which they seek to improve. They detect imperfections and they naturally want to correct them. They pay close attention to detail and seek to maintain high standards.
1s are motivated by the development of the quality of what they do and are constantly looking for progress. They act according to their standards, their moral beliefs and their principles. They feel the need to live with integrity and constantly strive to improve themselves, others, and everything around them.

Vice and defense mechanism

When they are under the influence of their compulsion (to avoid errors), the ego of 1s pushes them, under their vice: resentment, to correct all the errors they encounter in order to get closer to perfection. They are angry inside because nothing seems to them as fair as it should be, and in the same way their defense mechanism: the reaction formation, pushes them to repress this anger with effort, because for them, it is a lack of self control. If they consider their temptations as the cause of their torments, they start to do the opposite of the latter: if they are tempted to soften their work, they work much harder. Under the influence of their compulsion, they can become irritable and critical towards those who do not respect their high moral code and their need for organization and procedures.

In harmony

When they are in harmony with themselves and manage their compulsion, 1s are conscientious, involved in what they do, responsible, honest, reliable and practical. They are in confort when everything is organized and in accordance with the rules. Especially when things are going better than expected. So they tend towards their type of integration (type 7), and its positive traits are added to their behavior. So they can become more joyous, fun and witty. They become more creative, less conservative, and more open to new things.

In imbalance

Under the influence of their compulsion, 1s can become inflexible, irritated, too critical, emotionally repressed and rigid.
If the situation does not get better, they tend towards their type of disintegration (type 4), and its negative traits are added to their behavior. Thus they fall back on themselves, feeling misunderstood by their surroundings, and consider that their effort is not estimated. They then fall into a melancholy mood by believing that they have made efforts for nothing.
