Differences between LII (INTj) and LSI (ISTj)

1. When solving a problem, INTjs rely more heavily on their generalized past experiences than ISTjs. INTjs are inclined to use already prepared, preformulated methods and processes to solve a problem.

2. When getting ready to start a project, INTjs spend more time planning and preparing for the project than ISTjs. In particular, INTjs spend more time discussing the plan, discussing options and ways to approach the project, etc.)

3. INTjs tend to be more idealistic with their heads-in-the-cloud. ISTjs, on the other hand, are more realistic and down-to-earth.

4. ISTjs are more likely than INTjs to tackle a task in its entirety, rather than breaking it up into smaller separate stages.

5. When doing a task, ISTjs are inclined to work for the sake of the result (for example, a reward or bonus for completing the task). In contrast to INTjs, ISTjs can renounce their comforts and conveniences for this; ISTjs evaluate their place of work by looking at what returns they get for the effort they invested (e.g., monetary, prestige, etc.).

6. When solving a problem, ISTjs are more inclined (than INTjs) to solve it by relying predominantly on only the presently available information. Essentially, ISTjs will develop a process or method uniquely fitted towards the present problem, and this method is designed using the present conditions and information.

7. When planning to complete something, INTjs are more likely to focus their attention on the goal itself, overlooking and deprioritizing the individual actions needed to reach that goal. On the other hand, ISTjs tend to focus their attention on the each action; i.e., they're focused on how each decision and choice is being made (towards reaching the goal), in a step by step process.

8. ISTjs are more naturally comfortable with physical confrontations than INTjs.

9. When contemplating a task, it takes INTjs longer time to mobilize than ISTjs; i.e., INTjs prefer to spend some time in a more natural state of relaxedness which will then prepare them to subsequently mobilize and concentrate at the crucial moments, improving their performance.

10. When developing a plan of action or process, ISTjs tend to see themselves as "within the process"; they are immersed in it. Often because of this, they have more difficulty managing several plans at once. On the other hand, INTjs tend to place themselves "outside of the process"; they dissociate from it. For them the process or situation is something external from themselves.

11. INTjs attitude towards a specific person (more so than ISTjs) is based on their personal characteristics (authority, intellect, personal achievements, etc.) INTjs recognize superiority of certain individuals drawing from their personal qualities

12. ISTjs are able to change and make adjustments to their goals more easily than INTjs (depending on how progress is being made, etc.). INTjs on the other hand, prefer to stick with their original goals.

13. INTjs are often more interested in the idea or theory of something, whereas ISTjs are more interested in the actual practice or implementation of it.

14. ISTjs, more than INTjs, frequently perceives and defines themselves and other people through group associations. ISTjs focus on collectivism over individualism.

15. When discussing work, ISTjs are more likely than INTjs to focus on the fruits of their labor, about what their effort will yield. INTjs on the other hand are more likely to focus on the environment they work in, e.g., their work conditions, conveniences, commute time, etc.

16. INTjs are more focused on ideas and concepts than ISTjs. On the other hand, ISTjs are more focused (than INTjs) on their surroundings.

17. ISTjs are better at noticing details than INTjs. INTjs on the other hand, are better at seeing the big picture than ISTjs.

18. When it comes to completing a task, ISTjs are more likely than INTjs to mobilize for longer periods of time. Specifically, ISTjs tend to mobilize for an action early and stay mobilized for a longer period of time after the task has been completed. For ISTjs, this state of readiness is their natural state.

19. INTjs are rmore relaxed in their natural state than ISTjs. However INTjs will mobilize and concentrate when needed to accomplish an objective. After the task has been completed, INTjs demobilize again. This state of demobilization is the natural state of INTjs.

20. When conversing, ISTjs types are inclined to communicate in the form of monologues, where each party has "its turn." Because of that they subconsciously attempt to transform a dialogue into a series of monologues. Conversely, INTjs tend to prefer more of a question and answer style format.

21. When working on a project, INTjs experience more discomfort (than ISTjs) if the project does not have a clearly delineated end-goal or result. This happens because INTjs have more difficulty monitoring and understanding how the project is developing than ISTjs because they are outside of the process.

22. When ISTjs form opinions of others, these opinions are formed under the influence of their attitude towards the group to which the person belongs. To ISTjs, 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."

23. When describing their reasoning for their actions, INTjs (more so than ISTjs) tend describe how and why they came to a certain decision, and focus less on the timing and initiation of the action.

24. INTjs tend to judge their available options by how likely the option will help them reach their goal. If a choice no longer helps INTjs reach their goals, it will be dismissed and discontinued. On the other hand, ISTjs prefer to continue pursuing their current option, opting to adjust their ultimate goal in order to fit the current choice.

25. INTjs pay more particular attention to aspects of a situation or plan that are insufficient or lacking. This can be interpreted by others as INTjs having a negative assessment of various situations and events (.e.g, "the glass is half empty). On the other hand, ISTjs 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").

26. When describing why they undertook a project, ISTjs are more likely than INTjs to focus on the moment when a decision is made and to speak in detail about the stages of its implementation.

27. When working on a project, INTjs are more likely than ISTjs to break up larger tasks into several stages. Then INTjs mobilize to carry out each stage (and demobilize between the stages).

28. INTjs are more likely than ISTjs to perceive and distinguish themselves primarily through personal qualities. INTjs focus on individualism more than ISTjs.

29. ISTjs are often able to form quicker opinions of others they have just met than INTjs. This is based on the ability of ISTjs to draw conclusions about the person based on the groups the person belongs to; INTjs are more reluctant to make these inferences.

30. When assessing an option or available choice, ISTjs tend to focus more on how the choice could benefit them (what it would potentially yield) than INTjs would. On the other hand, INTjs would be more cognizant of the potential risks and potential losses that may accompany the decision that ISTjs may unconsciously minimize.
