I’ve been watching this video, and what I found interesting was when the narrator talks about how we are limited by the structures of our unconscious perception.
The narrator gives the example of walking down a street and taking in information around us and then forming that unconscious information into a conscious narrative about our experience. This is where I think it gets interesting in terms of cognitive functions. The narrator talks about how within a few weeks you’re unlikely to recall your experience of walking down a street. However, how we interpret that walk down the street would wildly differ depending on your cognitive function preferences. If you are a person who relies on kinaesthetic sensory functions like sight, smell, touch, hearing, in a few weeks you may recall something unusual you happened to notice on the street, a particular signpost or a piece of graffiti, the smell of a pub or stale beer in the air, you might overhear a conversation between a couple arguing. You might be a person who interprets the world through your values, so you might recall how that walk made you feel, because for example, you were going to meet a boyfriend or girlfriend in the knowledge that you had to have a difficult conversation, or you were nervous because you were on the way to a test. These are tangibles.
For an INTJ, the primary cognitive function is an unconscious perceiving one and then we try to make sense of that using extraverted thinking which is another abstract function. This differs from say, an ISTJ whose primary function entails them taking in information about their physical environment in a concrete literal fashion. As our primary function and secondary functions are abstract, in this instance we would likely have to rely on something triggering our inferior function, which is extraverted sensing, if we are to notice anything tangible at all in the environment. Then it would be down to the secondary abstract function, extraverted thinking, to interpret that information, and extraverted thinking being as it is, it isn’t inconceivable that the secondary function would disregard the information provided by the inferior function as being inconsequential and/or irrelevant. Thus, we may actually carry on walking down the street without effectively noting any specific details about this walk at all. Thus, even though it is likely that for the majority of the population they would be unlikely to particularly recall this walk a few weeks later, this is even more so the case for the INTJ. This is the problem we essentially run into as INTJ’s, when the secondary function doesn’t fully (if at all) engage with the inferior function, we may, for the most part essentially become disengaged from the physical world. We can be quick to disregard details and we are quick to shut out stimuli in the physical environment that may make us uncomfortable, so we can return to our thoughts and ideas, or our speculations about the future. Broadly speaking, the only time we would be likely to pay any sort of attention on this theoretical walk down the street is if introverted intuition was to register some kind of pattern, and even then we would be more concerned with deciphering the broader meaning of the pattern than the actual physical environment itself. Thus, you have the problem.
By the nature of our cognitive function stack, our relationship with the physical world can be an unhealthy one. As the INTJ is fundamentally operating at an unconscious level and the secondary function serves the primary function to provide interpretation, meaning and often for example, how that will impact upon the future, there isn’t a great deal of interest in what’s actually happening now. Generally, as a result, you will often find a lot of unhealthy behaviours in all of the intuitive dominant types, INFJ, ENFP and ENTP, such as smoking, drinking, drug use, poor diet, scattered appearance, this is by virtue of the fact that there is a separation between the dominant abstract function and the inferior sensory function which manages the persons interaction with the physical world or even the persons own physical body. You could in fact speculate that behaviours which by many types would be considered risky, unhealthy or even inappropriate might come about on some level due to a disconnect between the dominant abstract functions and the weak sensory function which manages the relationship with the physical world. This isn’t inconceivable, as for many intuitive dominant types, they may not even experience any sense of oneness with their own physical body. On a separate note, this relationship between cognitive functions and the relationship with the physical body and its various manifestations is one I would be interested to study. For example, I would theorise that the personality type most likely to experience transsexuality is the INFJ.
Although the extraverted intuitive has greater engagement and interest in the external world than the INTJ and INFJ, they will encounter similar problems in their actual relationship with the physical world again through the abstract nature of both their primary and secondary functions. For example, often ENFPs or ENTPs will have a certain clumsiness, although conversely that is through seeking meaning and understanding of the external world, which causes a detachment with the physical tangible experience, differing only from the INTJ or INFJ in the sense that for the INTJ or INFJ, their primary preoccupation is an introspective one. I would speculate that the reasons for risky and unhealthy behaviours in the intuitive introvert or the extraverted intuitive would be fundamentally diametrically opposite, although unerringly similar in terms of the manifestation.
