Program Function

Program function: mental, inert, strong, evaluatory, verbal {valued}, accepting.

Every individual is a micro-society in miniature, possessing a unique foothold in the world and an evolutionary role that no one else can fulfill. We all have an innate freedom of will and a distinct identity, yet whether this potential truly unfolds depends on the development of the Program Function (the first function in Model A).

The Program Function serves as the absolute core of the personality, shaping an individual’s entire worldview. It is the primary vehicle for self-expression and for tackling life’s global challenges. In fact, the essence of Model A is the fulfillment of this specific function’s goals, with all other functions acting in a supporting role.

The Filter of Reality

The Program Function acts as a primary filter through which all incoming information passes. It defines how a person perceives and conceptualizes the world. This processing often happens so naturally that the individual may not even realize they are wielded this innate strength.

Rational Functions: If the program is rational, the individual forms rigid requirements. The world mustcorrespond to their internal logic or ethics; they can become a "hostage" to their own program.
Irrational Functions: If the program is irrational, the individual forms rigid needs. For instance, Introverted Sensing creates a hunger for diverse sensory experiences, while Extroverted Intuition demands a constant flow of new information and possibilities to feed the imagination.

Tireless Efficiency and Professional Foundation

In the aspect of their Program Function, a person is capable of working tirelessly and effectively. It is their natural "battery." Because developing this function exponentially amplifies personal potential, it serves as the ideal foundation for choosing a profession or a lifelong hobby. While a person might feel they aren't "doing enough," they are often performing work of a scale and character that the average observer—or even the individual themselves—cannot fully grasp.

Psychological Properties: Confidence and Aggression

The Program Function possesses two critical behavioral traits:

Unshakable Self-Sufficiency: When a person is confident in their "program," they become effectively immune to external feedback. They may ignore both the compliments and the criticisms of others, as their internal conviction is so absolute that outside opinions lose their significance. While this provides great stability, it can lead to a refusal to adapt to situations where their position might be objectively inadequate.
Defensive Aggressiveness: Despite its strength, the first function is highly sensitive to restriction. When a person is "suppressed" or "oppressed" regarding their base aspect, it triggers a powerful negative response—ranging from cold aggression to uncontrollable emotional outbursts or hysteria.

Conclusion: The Path to Individuality

One's true potential is not guaranteed; it must be reclaimed. A person can either allow their Program Function to dominate and lead their life, or they can fail to exercise their will, becoming a mere "cog" in social programs. To master the Program Function is to move from being a component of the mass to becoming a fully realized individual.
