3.2 Psychological types  (Page 8/13)

Jung discussed how things are subjective to the introvert and objective to the extrovert - "Thus, just as it seems incomprehensible to the introvert that the object should always be the decisive factor, it remains an enigma to the extravert how a subjective standpoint can be superior to the objective situation. He inevitably comes to the conclusion that the introvert in either a conceited egoist of crack-brained bigot.". Jung means that an introvert biases information for himself, my guess would be that this is because he just doesn't care about other people. If you aren't paying attention to the other people in an interaction, it makes sense that you would be more focused on yourself. If you interact with people less, you care more about yourself and less about other people. The extrovert would be objective, because that way he might win the favor of others (instead of being self-centered). This statement shows how selfish Jung thought the introvert was - "The whole world-created force of the subjective factor becomes concentrated in the ego, producing a boundless power-complex and a fatuous egocentricity.".

In this paragraph Jung talks again about how the introverted thinking type is subjective with data:

• In the section on extraverted thinking I gave a brief description of introverted thinking (pars. 578-79) and must refer to it again here. Introverted thinking is primarily oriented by the subjective factor. At the very least the subjective factor expresses itself as a feeling of guidance which ultimately determines judgment. Sometimes it appears as a more or less complete image which serves as a criterion. But whether introverted thinking is concerned with concrete or with abstract objects, always at the decisive points it is oriented by subjective data. It does not lead from concrete experience back again to the object, but always to the subjective content. External facts are not the aim and origin of this thinking, though the introvert would often like to make his thinking appear so. It begins with the subject and leads back to the subject, far though it may range into the realm of actual reality. With regard to the establishment of new facts it is only indirectly of value, since new views rather than knowledge of new facts are its main concern. It formulates questions and creates theories, it opens up new prospects and insights, but with regard to facts its attitude is one of reserve. They are all very well as illustrative examples, but they must not be allowed to predominate. Facts are collected as evidence for a theory, never for their own sake. If ever this happens, it is merely a concession to the extraverted style. Facts are of secondary importance for this kind of thinking; what seems to it of paramount importance is the development and presentation of the subjective idea, of the initial symbolic image hovering darkly before the mind's eye. Its aim is never an intellectual reconstruction of the concrete fact, but a shaping of that dark image into a luminous idea. It wants to reach reality, to see how the external fact will fit into and fill the framework of the idea, and the creative power of this thinking shows itself when it actually creates an idea which, though not inherent in the concrete fact, is yet the most suitable abstract expression of it. Its task is completed when the idea it has fashioned seems to emerge so inevitable from the external facts that they actually prove its validity.
