Extraverted Thinking (Te)

Te channels energy outward to organize and structure external processes and environments. It evaluates causal relationships, implements systematic procedures, and optimizes for measurable outcomes. Te continuously integrates external information to refine procedures, ensuring that operations remain effective and directly applicable to the surrounding context.

Second Function: Same modality, variable energetic toll

Introverted Sensation (Si)

Si channels energy inward to interpret sensory input through subjective filters. Its process involves organizing and comparing incoming sensations to personal experiential impressions, producing internally coherent perceptual mappings. Si emphasizes qualitative and contextual representation of experiences rather than abstraction or prediction. 

Third Function: Opposite modality, variable energetic toll

Extraverted Intuition (Ne)

Ne projects energy outward to detect latent connections, potential outcomes, and emergent patterns in the environment. Its process involves generating and evaluating possibilities based on observed stimuli, linking disparate elements, and continuously scanning for novelty. Ne prioritizes adaptability and responsiveness to new input rather than direct validation against objective reality.

Fourth Function: The polar function, least natural to utilize, most energetic toll
