Evaluatory Functions

Evaluative Functions (Base, Vulnerable, Suggestive, Background) carry a fixed sense of "this is right/wrong for me."

Their primary question is: _"Is this mine? Does this match my idea of how things should be?"

How It Works

The evaluative function operates by comparing incoming information (objects, ideas, behaviors) against a stable internal standard of "how things should be." This standard is largely independent of external opinions. The result is a quick verdict: "Yes, it fits" or "No, it misses the mark."

Examples: What is Considered "Good"?

Ne (Extraverted Intuition): New, unusual, opening up opportunities. For example, an interesting idea that inspires experimentation.
Ni (Introverted Intuition): Timely, fitting into the overall "plot" or narrative. For example, an action that is "on time" and harmonious.
Te (Extraverted Logic): Efficient, delivering results. For example, a plan that actually works.
Ti (Introverted Logic): Logical, structured, without contradictions. For example, a clear system of rules.
Fe (Extraverted Ethics): Emotionally accurate, catching the right mood. For example, a speech that inspires the audience.
Fi (Introverted Ethics): Honest, preserving trust. For example, a relationship where boundaries are clear.
Se (Extraverted Sensing): Controlled, reliable. For example, a situation where you are in the driver's seat.
Si (Introverted Sensing): Comfortable, physically pleasant. For example, a cozy place to relax.

The Need for Certainty

This function requires clarity: a frame, coordinate system, or reference point. It can be an internal system of principles and pre-formulated positions rather than external rules, but it must be stable.

With certainty, the function operates confidently—"this is how it's right" and "this is the norm." Without it, discomfort arises (not necessarily anxiety, but noticeable tension). The person then seeks support—asking how things are usually done, recalling rules, or building their own coordinate system.

How It Sounds in Speech

People with an evaluative function in a given aspect tend to speak from a set position:

Not "it could be this or that" → but "generally, this is how it's done" or "normal is when..."
Not "I'm not sure" → but "the right way is..."

This is not rigidity or authoritarianism, but a functional need for a point of support. Without it, the function stalls.

Characteristic Behavior

In their evaluative aspects, people usually emphasize thinking things through and planning in advance: "I always find out how it works first" or "I need to understand the rules before I engage."

They feel discomfort in situations lacking clarity and will either create certainty themselves or express frustration at its absence. They often perceive others who treat the same aspect situationally as "uncertain," "floating," or "lacking a clear position." A response like "Well, it depends on the situation" can be irritating because it sounds like "I haven't thought about it."
