Introverted Sensing (A Comprehensive Guide)

The human brain is a fascinating subject and it performs tens of thousands of tasks and operates the human body.

Thinking, judging, sensing, memory, and cognition are just some of the functions of the human mind.

There are a lot more functions that are performed by the human mind.

It took years to understand the human brain and it would take ages to describe what we know so far about human brains.

Moreover, human beings only use a few percentages of their brain and they have been able to achieve much more.

Imagine if we were able to use our whole brain what could have we done.

The functions of the brain are a lot to encompass in a single article so we are going to discuss only one of the cognitive functions in detail. 

Along with a number of functions of the human brain there is one function called introverted sensing or SI.

The experience of introverted sensing is different for different people. Its usage depends on the development of this function.

It is a way of receiving information from the environment.

Before discussing how this function works, let’s discuss what introverted sensing actually is and how people develop introverted sensing and in which type of personalities it is found better.

In this article, we will discuss Introverted sensing.

  • What is introverted sensing?

In simplest terms, introverted sensing or SI is one of your eight cognitive functions and it has different development in different people depending on the age as well as the personality type of the person.

Introverted sensing is known to be one of the four ways of perceiving or taking in information.

The ways of perceiving information as follows

  1. Extraverted Sensing
  2. Extraverted Intuiting
  3. Introverted Sensing
  4. Introverted Intuition

We can understand introverted sensing while comparing it with extraverted sensing.

When it comes to extraverted sensing (Se) a person perceives exactly what the senses are telling him in real-time based on his five senses and their sensory experiences.

However, when it comes to Si, the person only perceives mostly stored memories of previous sensory experiences.

Hence, the person who uses introverted sensing will experience something in real-time but then a comparison will be made quickly to the stored in his mind.

For example, there is a quality assurance inspector in a widget factory and he has to look at widgets coming off the production line and then compare those widgets to a widget which is known to be a perfect widget.

The perfect widget has an already made image stored in the inspector’s mind.

A widget that is not in line with the perfect widget image can easily be detected and a person with higher introverted sensing has brains wired for this.

Another example can be taken of a gym trainer and he knows how to perform every single exercise because he has been trained in anatomy.

The trainer clearly knows how a person’s body should move and at which angle to perform the exercise to gain optimal results.

The breathing pattern, the lifting of weight, and everything else is planned in the trainer’s mind and an introverted sensor trainer can easily instruct the person about how to train perfectly. 

Introverted sensing is more interesting because the individual’s brain wiring makes the comparisons and it also shows what is different from the memorized image and the widget brought to them.

People who have dominated introverted sensing have brains which can vividly recall the past experience with the stored emotions.

They can relive a past event or re-experience it as it was happening before their eyes or it is just like the event that passed yesterday.

They can revisit the feelings at the moment of the event and the emotions at the time of the event happened which can also help them in memorizing the key moments of their life and to keep track of different life events.

It is one of the special qualities found only in people with high introverted sensing. 

  • How to know about introverted sensing

There are a few signs which needed to be known if you wanted to know if you have the function of introverted sensing developed.

Some people who are introverted sensors have reported that it happens like there was a movie playing in their head which brings them back to the real event experiencing it as the event was happening live.

Some of them also see them in a surrealistic way just like a surrealistic painting.

Some others that are known if you are an introverted sensor are given below.

  1. You Enjoy Reliving the Past 

You are the type of person who likes to enjoy recalling and reliving past experiences.

You can just feel how it happened and how it made you feel.

You like to look at videos and photos which make you remember the past experience as it has recently happened.

You like to reminisce and like to have a certain kind of nostalgia.

You know that even a lot of photos and videos have nothing compared to the images and feelings stored in your mind. 

  1. You Learn Quickly From Your Mistakes

You are a person who learns from his mistakes really quickly and the personal experience meant a lot to you because that’s when you realize wrong patterns of things.

You keep on making mental notes so you don’t repeat the same pattern of behaviors again.

Therefore, if you are learning quickly from your mistakes then you are an introverted sensor. 

  1. You Compare A Lot

You easily notice the inconsistencies and changes occurring in the environment for the people you care about.

You are so good at noticing the changes that even a smaller thing can’t go unnoticed by you.

You can easily tell if someone’s behavior or attitude has changed towards you or towards someone that you love.

You notice if a new thing is either similar or different from the things you have experienced before.

You can tell if a current experience does not line up with the one in the past.

You think a lot about the impact a change is going to have on current events and what other similar changes can make it into a better or a worse one.

  1. You are Organized

You like to move things structurally organized around you. You are painstaking about your work and you want everything to move systematically.

You have to move from A to B to C and don’t want to move around things. You do not prefer shortcuts.

Everything needs to be moved in an orderly fashion around you. 

  1. Your Conversation Needs to be Realistic

You like discussion philosophies and theoretical implications of these philosophies but you crave realistic discussion.

You want to discuss things that are applicable to your real-life now. You like to have planned and you want to plan ahead of different things.

You easily get bored with the discussion if it doesn’t have real-life implications. Discussions that don’t have a practical purpose can make you easily restless.

You like to talk more about activities, projects, and goals rather than inspirations and theories.

You want your discussions to have the real-world application of your conversation and you want to create an impact because it means more to you that the world around you becomes a better place. 

  1. You Want to Have a Routine Structure to your Day

You don’t like surprises and you want your day to be carefully planned. You want to know what to expect because knowing what to expect and looking forward to a familiar routine and schedule makes you feel relaxed and calm in your life.

You like to have your meals at a specific time in the day.

You want everything scheduled and carefully planned like doing your shopping at a specific place at a certain time.

These things make you relax and lower the sensory load on your senses.

It is comforting to know that you have a carefully planned routine for you. 

  1. You have a Vivid Memory of Important Things

Significant details of your past which are important to you are carefully and vividly stored in your memory.

You even remember the smallest details like what clothes you wore on your 7th birthday and what weather it was like it has the smell of freshly blossomed flowers around you.

You remember the perfume your friend used to wear or what your first cell phone looks like. You also remember what your first bike looks like and who gifted it to you.

It can’t be said that you remember everything perfectly but you remember things vividly which were important to you and have grave personal importance. 

  1. You Witty Sense of Humor

You seem to be very serious but on the inside, you really enjoy noticing many details and relationships and impressions which other people often seem to miss.

You tend to see the humor in many situations when other people ignore or don’t seem to notice.

You are really witty and your sense of humor is on point (almost every time) but you don’t like to show off.

People who do not know you well are often surprised by your offbeat sense of humor because they do not think of you as a funny guy. 

Side Note: I have tried and tested various products and services to help with my anxiety and depression. See my top recommendations here, as well as a full list of all products and services our team has tested for various mental health conditions and general wellness.

  1. You Trust Facts

Truth means a lot to you and you tend to prefer facts over inspirations. You don’t dwell on hopes or dreams or inspirations because abstract and unproven thoughts make you skeptical and you would like to have facts.

You are known to be a practical down to earth person and you like to use old school tried and true methods while you are working instead of new and non trusted ways.
