This may help clear certain things up. I'll quote directly from Isabel Briggs Myers 'Gifts Differing' page 80 on Comparison of Extraverted Sensing and Introverted Sensing:
Se: Suppresses as far as possible the subjective element of the sense impression.
Si: Suppresses as far as possible the objective element of the sense impression.
Se: Values the object sensed rather than the subjective impression, of which he may hardly be aware of.
Si: Values the subjective impression released by the object rather than the object itself, of which he may hardly be aware of.
Se: Sees things photographically, the impression being one of concrete reality and nothing more. The "primrose by a river's brim" is simply a primrose.
Si: Sees things highly colored by the subjective factor, the impression being merely suggested by the object coming out of the unconscious in the form of some meaning or significance.
Se: Leads to concrete enjoyment, seizing very fully the momentary and manifest existence of things, and that only.
Si: Leads to ideas, though the activation of archetypes, seizing the background of the physical world rather than its surface.
Se: Attention riveted by the strongest stimulus, which invariably becomes the center of interest, so that life seems wholly under the influence of accidental outer happenings.
Si: Attention very selective, guided wholly by the inner constellation of interests, so that it is impossible to predict what out stimulus will catch and hold attention.
Se: Develops a pleasure-loving outer self, very rich in undigested experience and unclassified knowledge of uninterpreted facts.
Si: Develops an extremely eccentric and individual inner self, which sees things other people do not see, and may appear very irrational.
Now that Si is clearly defined - combine the definitions of Si with Te aka ISTJ (page 78):
Te: Is fed from objective data - facts and borrowed ideas.
Depends upon the facts of experience and regards the abstract idea as unsubstantial and of negligible importance.
Soundness and value lie less in the thinker than outside in the facts, which are more decisive than the thinking itself.
Goal is solution of practical problems, discovery and classification of facts, criticism and modification of generally accepted ideas, planning of programs and developing of formulas.
Dwells upon the details of concrete case, including irrelevancies.
Danger lies in tendency to multiply facts until their meaning is smothered and thinking is paralyzed.
Consists of a succession of concrete representations which are set in motion bot so much by an inner thought activity as by the changing stream of sense perceptions.
Take the Definitions of Si and combine with Fe(page 79) aka ISFJ:
Fe: Determined chiefly by the objective factor, it serves to make the individual feel correctly, that is conventionally, under all circumstances.
It therefore adapts the individual to the objective situation.
Depends wholly upon the ideals, conventions, and customs of the environment, and is extensive than deep.
Its soundness and value do not lie in the individual, but outside int he collective ideals of the community, which are usually accepted without question.
Its goal is the formation and maintenance of easy and harmonious emotional relationships with other people.
Expresses itself easily and so shares itself with others, creating and arousing similar feeling, and establishing warm sympathy and understanding.
Danger lies in the tendency to suppress the personal standpoint entirely, and become a feeling process instead of a feeling personality, giving the effect of insincerity and pose.
Take the definitions of Fe above, apply it as auxiliary, combine with Ni(page81) aka INFJ:
Ni: Uses the objective situation in the interests of the inner understanding.
Regards the immediate situation as a prison from which escape is urgently necessary, and aims to escape through some sweeping change in the subjective understanding of the objective situation.
Receives its impetus from outer objects but is never arrested by external possibilities, being occupied rather by searching out new angles and understanding life.
May be creative in any field: artistic, literary, inventive, philosophical, or religious.
Finds self expression difficult.
Greatest value lies in the interpretation of life and the promotion of understanding. Requires the developmental of balancing judgment, not only for the criticism and evaluation of intuitive understanding, but to enable it to impart its visions to others and bring them to practical usefulness in the world.
Combine Ni as defined above with Te(page 78) aka INTJ:
Te: Is fed from objective data - facts and borrowed ideas.
Depends upon the facts of experience and regards the abstract idea as unsubstantial and of negligible importance.
Soundness and value lie less in the thinker than outside in the facts, which are more decisive than the thinking itself.
Goal is solution of practical problems, discovery and classification of facts, criticism and modification of generally accepted ideas, planning of programs and developing of formulas.
Dwells upon the details of concrete case, including irrelevancies.
Danger lies in tendency to multiply facts until their meaning is smothered and thinking is paralyzed.
Consists of a succession of concrete representations which are set in motion bot so much by an inner thought activity as by the changing stream of sense perceptions.
