INTJ vs ISTJ

INTJ

The Scientist

ISTJ

The Inspector

Personality

The INTJ is the patient visionary clear on how the future should look and will work with quiet, logical determination to make it happen. The INTJ loves an intellectual challenge and is stimulated by the abstract, the complex, the new and the untried; facts and figures bore them. They can seem a little detached from others as they quietly process so much information inside their heads.

Logical, detached and detailed, ISTJs use their experience and store of knowledge, to plan and will work quietly and steadily behind the scenes towards conclusion. The ISTJ has a strong sense of duty, loyalty and tradition and once they are clear on what’s expected, they will work in a methodical way to complete. Risk averse they prefer the known, and prefer facts to concepts.

At Work

We all bring something different to the team and we all agree that difference and balance are good things. However when someone is different from us we might not understand them so well so in this section we allow you to compare the differences at work, how these might manifest themselves and how best to manage them.

Contribution to the team

INTJs will overturn established practice be forward thinking and truly radical. They love the intellectual challenge, coming alive with difficult problems to solve then step back again when it becomes mundane.

Contribution to the team

ISTJs bring a strong sense of planning, agreeing objectives and working steadily towards closure. They have a strong eye for detail and can therefore protect the team from going off in a wrong direction.

Leading

The INTJ will be at their best with the facility to work for long periods on their own. If they do lead they prefer like-minded people who also love the intellectual debate and complex challenges.

Leading

ISTJs will be great at ensuring everyone is clear on what is expected, everyone knows what the plan is and their part in it and ensuring that the plan is enacted, so more task- than people-focused.

Being managed

The INTJ will often find the mundane and routine tedious and energy sapping and may prefer individual contribution excelling at deep diving and working on the unique, the interesting and the complex.

Being managed

Best managed by clear tasks, ISTJs need plenty of time to fully understand what is expected then let them get on, working with consistent steady energy towards completion, not micro managed.

Attention to detail / focus

INTJs are perfectionists, with an endless capacity for improving upon anything that takes their interest. They will work long and hard on such tasks, driving towards closure, impervious to the outside.

Attention to detail / focus

ISTJs have and incredible eye for detail, focus and a desire to drive for closure. They will want to slowly assimilate information and be sure of their facts before moving forward and this will be as per the plan.

Creativity

INTJs are ideas people. Anything is possible. INTJs love developing unique solutions to complex problems, and, conversely, if it were not complex or interesting then why would they bother?

Creativity

ISTJs are more factual than creative and their value is exactly that: ensuring that was has been agreed is delivered exactly as agreed and translating everything into a plan that is clear and can be delivered.

Conflict

Some people seek harmony, some see conflict as simply robust discussions, some people are emotional, some more factual. So there is no right or wrong about this and what we are trying to do is help two different people each understand how the other might deal with conflict and what it will mean for how they work together.

Initial response to conflict situations

The INTJ is often impervious to their environment as they are deep and private and love getting their heads into complex problems. They love the intellectual robust debate and won’t really ‘see’ conflict.

Initial response to conflict situations

ISTJs prefer to keep themselves to themselves and so in conflict situations they will struggle with overt conflict, ie with someone who wants to engage verbally. They are fine with more formal conflict.

Issues they'll fight on

For the INTJ it is about creating something new and worthwhile and this will be their focus. They won’t really see the emotional issues and will work at a more cerebral level where they are more comfortable.

Issues they'll fight on

ISTJs have a strong sense of right and wrong and this tends to be around what has been agreed. They believe if you have said you’ll do something then it is akin to a contract and you should fulfil that

Conflict style / communication

INTJs work more at an intellectual than emotional level and so would see conflict, if they did engage, as simply an extension of the debate and their arguments would be well thought through, based on data.

Conflict style / communication

Formal processes such as writing letters of complaint or going through the proper channels plays to ISTJ strengths. They are measured and formal and so will be very factual and non-emotional.

How they feel after

As the INTJ inhabits an internal world of complexity, ideas and possibilities, working towards conclusion, any conflict would simply be seen as part of that process, enacted then it’s time to move on.

How they feel after

It is all about right and wrong. ISTJs do not like conflict if it involves emotion, as they prefer to see things far more factually and in a binary way. For them it will be about did it play out fairly and as agreed?

Interpersonal

We all have different motivators, values and views on the world, in part driven by our personalities. The section below describes how each person is likely to engage with others, and how others may see them.

Being around them

For the INTJ everything has a scientific base so getting close would be difficult initially, as they don’t see the need for emotional connection. Their engagement tends to come via intellectual arguments with like-minded people.

Being around them

Because of their intense focus ISTJs may be seen as slightly detached, cold and impersonal, possibly even as uncaring. This is not deliberate but it can alienate those trying to get close or get to know them.

Dealing with emotions

For INTJs emotion doesn’t compute and so they may not understand their impact on others or indeed gauge the emotional reactions of others, which can make them appear as insensitive or a little cold.

Dealing with emotions

Detached and factual ISTJs often find it difficult to deal with emotions as they see this as irrational and when others display emotions they have to translate the emotion into factual language that they can understand.

Openness and sharing feelings

INTJs are private and can often be naturally impassive as well, which makes them easy to misunderstand. INTJs want people to make logical sense and so feelings are difficult for them to fathom.

Openness and sharing feelings

Deep and private ISTJs will tend to keep their feelings to themselves and until they have the measure of people will be unlikely to proactively share their feelings. Too much interaction sucks their energies.

Drivers and values

INTJs are intellectually curious and love complex problems and analysing data to and come up with unique solutions, driven more by concepts and abstract ideas than by the emotions of people.

Drivers and values

ISTJs like people to stick to agreements and commitments and may not understand that this is human nature, not human deficiency as they themselves take such commitments incredibly seriously.
