Type Comparison: ILI (INTp) and LSI (ISTj)

Socionics Characteristics

Observable Differences in Behavior

  1. ILI are more likely than LSI to perceive and distinguish themselves primarily through personal qualities. ILI focus on individualism more than LSI.
  2. ILI attitude towards a specific person (more so than LSI) is based on their personal characteristics (authority, intellect, personal achievements, etc.) ILI recognize superiority of certain individuals drawing from their personal qualities
  3. LSI, more than ILI, frequently perceives and defines themselves and other people through group associations. LSI focus on collectivism over individualism.
  4. When LSI form opinions of others, these opinions are formed under the influence of their attitude towards the group to which the person belongs. To LSI, it is incomprehensible how it is possible to belong to two opposing groups at the same time:, i.e., "you're either with us, or with them and against us."
  5. LSI are often able to form quicker opinions of others they have just met than ILI. This is based on the ability of LSI to draw conclusions about the person based on the groups the person belongs to; ILI are more reluctant to make these inferences.
  6. ILI tend to be more idealistic with their heads-in-the-cloud. LSI, on the other hand, are more realistic and down-to-earth.
  7. LSI are better at noticing details than ILI. ILI on the other hand, are better at seeing the big picture than LSI.
  8. ILI are more focused on ideas and concepts than LSI. On the other hand, LSI are more focused (than ILI) on their surroundings.
  9. LSI are more naturally comfortable with physical confrontations than ILI.
  10. ILI are often more interested in the idea or theory of something, whereas LSI are more interested in the actual practice or implementation of it.
  11. When solving a problem, ILI rely more heavily on their generalized past experiences than LSI. ILI are inclined to use already prepared, preformulated methods and processes to solve a problem.
  12. When solving a problem, LSI are more inclined (than ILI) to solve it by relying predominantly on only the presently available information. Essentially, LSI will develop a process or method uniquely fitted towards the present problem, and this method is designed using the present conditions and information.
  13. ILI pay more particular attention to aspects of a situation or plan that are insufficient or lacking. This can be interpreted by others as ILI having a negative assessment of various situations and events (.e.g, "the glass is half empty). On the other hand, LSI pay more attention to what is actually present in a situation, and this can be interpreted as an affirmative or positive manifestation of the surrounding world, situations, possibilities, and prospects (e.g. "the glass is half full").
  14. When assessing an option or available choice, LSI tend to focus more on how the choice could benefit them (what it would potentially yield) than ILI would. On the other hand, ILI would be more cognizant of the potential risks and potential losses that may accompany the decision that LSI may unconsciously minimize.
  15. LSI are relatively better at assessing the emotional atmosphere occurring in a group or during an activity than ILI.
  16. When meeting someone knew, LSI are not as likely as ILI to perceive "getting to know somebody" as a special kind of activity. LSI know very well whey they are getting acquainted (i.e., what the purpose of the relationship is, be it business, personal, travel, etc.). LSI, in contrast with ILI, do not divide the process of getting acquainted into consecutive stages; rather LSI immediately establish the necessary emotional distance in contact and can regulate it if needed. To bridge the gap between poorly acquainted people in a group LSI amp up the emotional tone; this can be mutually experienced happiness or misfortune. The name and title of the person are of secondary relevance to LSI and their relationship with the other person.
  17. ILI are more likely to believe in objective truths than LSI. That is, ILI are more likely to believe there is a correct or best way of doing something than LSI.
  18. LSI are more inclined to believe there are relative truths than ILI. That is, this relativity is perceived by LSI as an extenuation of the differing beliefs, opinions, intentions, etc. of each person.
  19. When something is perceived by ILI as being incorrect, they are more likely (than LSI) to tell the person who made the error what they did wrong and how to do it the right way. ILI are focused on who made the error and helping them to correct the mistake.
  20. When something is perceived by LSI as being incorrect, they are more likely (than ILI) to ask why it was done that way. Instead of necessarily trying to correct the person who made the error, LSI attempt to understand the person's reason for their decision/action.
  21. ILI tend to internally combine emotional exchanges with other activities rather than separating them out like LSI. E.g., ILI see having fun occurring simultaneously with other activities, such as work or even serious affairs. LSI are more likely to internally separate out having fun with other activities, although the two can be interchanged at a high frequency.
  22. The "comparison and verification of concepts" is a more common phenomenon among LSI than ILI. This comparison not only concerns LSI methods, but also their understanding, terminology, etc. LSI are attuned to the fact that different people might understand and interpret different concepts and terms differently. They perceive terminology as well as actions of other people as part of the subjective concept inseparable from personal opinion, position, intent, etc. In contrast to ILI who perceive terminology as "objective," LSI understand personal differences behind terminology (this applies even to well established terms) and they attempt to compare and verify them.
  23. ILI are not as inclined to compare and verify concepts as LSI. ILI assume that these can have only one unique interpretation (the "correct" interpretation), and ILI often do not think about the fact that the other person may be interpreting them differently. Much more than LSI, ILI apply concepts such as "objective reality," "unequivocal facts," and de-emphasize concepts; ILI consider that they know the "right" way of doing things, how something "truly is," etc.
  24. ILI are more likely (than LSI) to use special rituals or other culturally accepted formalities when forming relationships with others. What that means is that the emotional proximity and relationship status for ILI be more externally predetermined. Additionally, ILI generally progress in relationships through stages, and therefore are more familiar with these stages than LSI. ILI tend to be more linear in their relationship progression than LSI, and ILI assign importance to the formalities of recognizing the start and end to each of these stages.
  25. LSI tend to plan ahead, making decisions early. On the other hand, ILI tend to prefer a wait and see, more spontaneous approach.
  26. ILI are relatively more flexible and tolerant than LSI.
  27. LSI are relatively more rigid and stubborn than ILI.
  28. ILI are comfortable making changes and adjustments to their decisions quite frequently. LSI, on the other hand, prefer to not make changes to their decisions.
  29. LSI tend to put more effort than ILI into finishing any new project they start.
  30. ILI tend to start more tasks and other projects than LSI, but the ILI are less likely to complete all of them.
  31. LSI tend to have stiffer more angular movements. ILI tend to have more relaxed fluid movements.
  32. ILI tend to have a more democratic leadership style than LSI.
  33. LSI tend to have a more authoritarian, hierarchical leadership style than ILI.
  34. ILI have a relatively higher stress tolerance than LSI. LSI often struggle with continually changing situations more than ILI do.
  35. LSI tend to perceive events in an episodic manner, i.e., they see events evolve in discrete states rather than continuous changes. On the other hand, ILI tend to perceive events in a continuous sequence; i.e., they see events evolving fluidly rather that one state to the next.
  36. When describing the stages of an event, ILI are more likely to focus on how stage A leads to stage B, how stage B leads to stage C, etc. LSI, on the other hand, focus more on the stages themselves without necessarily seeing or emphasizing the transitions or causes and effects of the stages to the extent that ILI do.
  37. When describing reality, LSI are more likely to talk about the properties and structure of reality. ILI are more likely to describe reality as movements, interactions, and changes.
  38. LSI are more likely (than ILI) to seek new and novel experiences rather than returning to something already lived through. They will generally only re-read a book, re-watch a movie, or revisit the same place if they have forgotten it or are hoping to learn something new from it.
  39. ILI are more likely than LSI to use "emotional anchors" that resonate with their internal emotional condition. These emotional anchors could be a book, a movie, a place, a song, etc. ILI use these anchors to strengthen their inner emotional state and thus will repeat the experience: e.g., re-reading a book, re-watching a movie, continually going back to a place to experience the emotions associated with it.
