Observable Differences in Behavior
1
LSI tend to plan ahead, making decisions early. On the other hand, IEI tend to prefer a wait and see, more spontaneous approach.
2
IEI are relatively more flexible and tolerant than LSI.
3
LSI are relatively more rigid and stubborn than IEI.
4
IEI are comfortable making changes and adjustments to their decisions quite frequently. LSI, on the other hand, prefer to not make changes to their decisions.
5
LSI tend to put more effort than IEI into finishing any new project they start.
6
IEI tend to start more tasks and other projects than LSI, but the IEI are less likely to complete all of them.
7
LSI tend to have stiffer more angular movements. IEI tend to have more relaxed fluid movements.
8
IEI tend to have a more democratic leadership style than LSI.
9
LSI tend to have a more authoritarian, hierarchical leadership style than IEI.
10
IEI have a relatively higher stress tolerance than LSI. LSI often struggle with continually changing situations more than IEI do.
11
LSI are more likely to make decisions based on logical reasons than IEI, who are more likely to make decisions based on their own feelings.
12
IEI are often better at solving and minimizing interpersonal problems, where as LSI often struggle understanding them.
13
LSI are often more interested in studying systems, structures, and functionality than IEI.
14
IEI tend to prefer using persuasion as a means of convincing others to do something, where as LSI prefer to use argumentation as a means of convincing others.
15
IEI are more vulnerable to logical manipulation than LSI. However LSI in contrast, are often more vulnerable to emotional or ethical manipulations than IEI.
16
LSI place greater value on their interests than IEI. For example, LSI will maintain high levels of energy and focus on an interest they value, even deprioritizing their other resources to maintain the interest. For example, LSI may spend a large amount of energy on an interest they value, often to the detriment of their time, sleep, relationships, money, etc.
17
IEI place greater value on their resources than LSI. For IEI, resources like their money, time, sleep, etc., fall into their "inner personal space," and the IEI will be more likely to deprioritize an interest if it starts to drain these resources too much.
18
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, IEI tend to perceive events in a continuous sequence; i.e., they see events evolving fluidly rather that one state to the next.
19
When describing the stages of an event, IEI 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 IEI do.
20
When describing reality, LSI are more likely to talk about the properties and structure of reality. IEI are more likely to describe reality as movements, interactions, and changes.
21
IEI tend to be more idealistic with their heads-in-the-cloud. LSI, on the other hand, are more realistic and down-to-earth.
22
LSI are better at noticing details than IEI. IEI on the other hand, are better at seeing the big picture than LSI.
23
IEI are more focused on ideas and concepts than LSI. On the other hand, LSI are more focused (than IEI) on their surroundings.
24
LSI are more naturally comfortable with physical confrontations than IEI.
25
IEI are often more interested in the idea or theory of something, whereas LSI are more interested in the actual practice or implementation of it.
26
When solving a problem, IEI rely more heavily on their generalized past experiences than LSI. IEI are inclined to use already prepared, preformulated methods and processes to solve a problem.
27
When solving a problem, LSI are more inclined (than IEI) 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.
28
When developing a plan of action or process, LSI 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, IEI tend to place themselves "outside of the process"; they dissociate from it. For them the process or situation is something external from themselves.
29
When working on a project, IEI experience more discomfort (than LSI) if the project does not have a clearly delineated end-goal or result. This happens because IEI have more difficulty monitoring and understanding how the project is developing than LSI because they are outside of the process.
30
When conversing, LSI 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, IEI tend to prefer more of a question and answer style format.
