The Myers-Briggs® MBTI® Test ISTJ Personality Type and Communication Differences.

We have all heard the saying that “Communication is Key”. Communication can often be misunderstood between two individuals and we have to wonder why this is? Why is that at times one individual might state something clearly and with no ill intent, while another individual receives this expression in a different manner or tone then the original intent of the expression? Well, as humans we differ, more specifically we differ by The MBTI Test 16 Myers-Briggs® Personality Types, and often enough our differences can cause us to communicate differently. The way in which we prefer to exchange verbatim varies and the end result of what we wish to express can at times be misunderstood. In this blog we will discuss the first MBTI® Test Personality type; The ISTJ Myers-Briggs Test Type and will continue on to the other 15 personality types as we continue this blog series on The MBTI and Communication differences.

The ISTJ Personality Type (Introverted-Sensing-Thinking-Judging Type) has a particular way of communicating that according to The Author Donna Dunning in the text “Introduction To Communication” states that ISTJ Types communicate in a “straightforward, practical, logical and efficient way”.  This directly relates to an ISTJ’s personality preference of Thinking and Sensing with logical decision-making and factual information gathering.  In other words, ISTJ Personality Types are not one’s for small talk.

The Communication characteristics of the logical ISTJ can at times be taken personally by others, especially by Extraverted-Feeling Types who might feel that ISTJ’s are being rude when in actuality they simply prefer to be more straightforward and to the point when verbalizing. It is important to understand that the ISTJ’s way of communicating is simply who they are, and it is not their intent to harm other’s feelings.

To further understand The ISTJ Type, we must understand that they are adept at recalling information through skills and knowledge they have attained through life practices and will often refer to these facts and informational details during discussions and communication. Furthermore, according to Dunning, when communicating their opinions or feedback to others, ISTJ’s are “clear and matter-of-fact” and tend to communicate their opinions in the form of “corrective” ways more so than in “positive feedback” (Dunning, D. CPP, 2003).

ISTJ’s are Introverted Types of personalities, which are known to be less communicative in larger groups or with multiple listeners then Extraverted Personality Types, such as ENFP’s-the ISTJ’s opposite. Extraverted Personality Types gain life energy from communicating and relating to others and are generally more out spoken. ISTJ Personality Types prefer to be more selective with whom they communicate with and to what length, as too much communication can be quite draining for an ISTJ, leading to internal problems and sometimes-even burnout, which we all wish to avoid. When dealing with an ISTJ, it is important to understand this and take into account that this type of individual simply prefers more straightforward and to-the-point communication then other types of personalities- especially that of Extraverted Types.
