The following is a general listing of all the major behavioral qualities statistically correlated to Si development. The focus of this article is to paint as complete and undiluted a picture of Si's behaviorism as possible, in an abstract sense and without modulation from any adjacent functions in a type's hierarchy.
The Si user lives and views life through narratives; understanding how things are connected through a chain of past events, and how the present is but the most recent moment in a long link of events that are intrinsically interdependent. Because of this orientation towards the roots of things, all the more value is added to something by knowing its background. A great richness is felt by learning how it is that a city came to be what it is, or how the shops in town came to be famous. Through these anecdotes, the Si user's comprehension of life multiplies and there is great joy felt in learning how the "here and now" fits into a much wider context. This will lead Si users to be avid readers as well as storytellers. They may sit at the feet of their grandparents and listen to old tales and later come to tell their own. They may particularly enjoy "based on a true story" films and appreciate learning about history --including their own. They may be elated to learn that their great great grandfather was a duke or king, and may voyage on an ancestral quest driven by a search of identity; an answer to "who am I?" that is rooted in a concrete reality. The Si user often stumbles into subjects such as world events, geography and anthropology in an effort to understand "what is this place, really?" They may be driven into an academic direction and become bookworms or librarians. More than a few Si users are also paleontologists; a domain driven heavily by the quest to discover what the links are between the earth as it was before and how it is today. The more complete a picture can be formed, the more grounded the Si user will feel in their paradigm and place in the world.
As they go about life, the Si user will also be passively accumulating mountains of information from everyday occurrences which, over time, come to form a vast mental archive of details. A few Si users may find themselves able to mention what they were doing four weeks ago on a Tuesday afternoon. Others may not have their talent fixed in chronological time, but be able to recite the names of all the past presidents, all the states or the actresses in old films. They may like to watch "Who wants to be a millionaire" and enjoy trivia games such as Jeopardy. Some Si users are generalists; knowing a little about a whole lot of things. Others are specialists, and know everything about one field of study. If they're into camping or hiking, they may have memorized all the herbs and flora of their specific corner of the world. On a backpacking trip they may call out: "See that? that's poison oak, don't touch that. And this one over there, you see the white stripes? That means it's ok to eat." Little factoids of this nature will follow them around at all times, and those who live with an heavy Si user will note their voluminous body of knowledge.
The Si user will be thorough when it comes to sharing information; intrinsically understanding that knowledge requires a proper context or backstory in order to be meaningfully received by others. Whenever giving an explanation, the Si user will tend to append the appropriate information to each explanation which can then fully unpack it and give the desired understanding. Just as the Si user would expect to be mistaken if they extrapolated a trend from missing data, they will expect others to also misread their meanings if forced to fill in the blanks they leave in their words. They will be very thorough in this manner, taking the extra steps to make their personal story, argument, idea or thought relevant and meaningful by painting a fuller picture of the ideas that surround and embed it. But often times the Si user may overdo it; expecting less context to be understood than what already is. They may lay down seven datasets before conveying their core idea, only to realize the same thought could have been relayed with three. This may lead others to view the Si user as rambly, perhaps repeating information that's already known or unnecessarily inflating the conversation. Over time the Si user may discover where the right balance is and be able to supply just the right amount of information for any given situation.
