Both aspects involve citing or listing facts and data; in

citing data serves to specify the subject of discussion and the order of listing is irrelevant, while in
![Introverted Logic](images/smilies/Ti.gif)
it reflects the information's internal structure. Also in common between the aspects is the theme of discussion - expressing and substantiating one's thoughts, as well as the habit of referring to the functioning of living things (people) as if they were mechanisms.
![Extroverted Logic](images/smilies/Te.gif)
essentially treats facts and data as external, autonomous objects (emphasizing facts, details, principles, algorithms, and the act of expressing them), while
![Introverted Logic](images/smilies/Ti.gif)
perceives data in the context of its structure and organization (emphasizing constructions, models, proper organization of data, outlines, systems, and structures).
![Extroverted Logic](images/smilies/Te.gif)
focuses on the what and the how of facts and data, while
![Introverted Logic](images/smilies/Ti.gif)
focuses on the why - the logical basis of assertions.
![Extroverted Logic](images/smilies/Te.gif)
focuses on the external proof of assertions - facts, examples, illustrations, concrete data and its interpretation - while
![Introverted Logic](images/smilies/Ti.gif)
focuses on internal proofs of the logic of statements and the consistency of logical principles applied.
