INTP vs ISTJ

INTP

The Engineer

ISTJ

The Inspector

Personality

The INTP is deep, private, difficult to know and extremely independent. They focus on things that interest them most putting off completing tasks until the last minute as the routine bores them. INTPs love logic and an indicator of being an INTP is obsession with logical correctness. An INTP will struggle with emotion, great at reading situations but less good at reading people.

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

Although quiet the INTP will come to the fore at analysing problems and evaluating ideas using their superb judgement and serious, unemotional nature to ensure the team makes balanced decisions.

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

INTPs need those around them to be proactive and not keep coming to them with questions. They like arguments and actions to be well thought through and will excel at ensuring this is the case.

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 INTP will not fit snugly into a typical structure. They value independence, of thought and action and they need their space: to think, to be free from other people to work in short bursts of energy.

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

The INTP does not like too much detail, preferring a broad-brush stroke approach. The simple, the obvious bores them and anything they see as trivial or unimportant will be pushed away.

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

If it holds their interest the high critical thinking ability of the INTP and their shrewd judgements means they can analyse and distil even the most complex problems and cut to the core of what needs to be done.

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.

Culture fit

How will an INTP fit with your team? Often, when recruitment decisions go wrong, we realise that it was all about personal chemistry. Assess potential candidates for your team

Culture fit

Knowing the real drivers, motivations and aspirations of an ISTJ, and their unique strengths, helps you see how they will fit into your team. Assess potential candidates for your team

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

Rational argument, logic and intellectual theory are the routes to the ‘heart’ of the INTP who will have no problem taking the hard decision, as long as it is the 'right' decision, one based on logic and evidence.

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

INTPs are relatively easy-going until something violates a principle. Then they can become outspoken, inflexible and unreasonable, switching from reserved to actually enjoying the heated drama.

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

Blunt and to the point, the INTP will rarely let emotions get in the way and will use logic and data to make their point. Those who are more emotional may find them at such times a little cold and harsh.

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 they are more deep and private the INTP will happily debate, using all their intellectual and logical abilities, before withdrawing back to their own world, not hard feelings, no feelings at all, it was a chat.

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?

Creating harmony

Understanding INTPs pressure points will help you adapt to one another. We all ‘get’ people who are like us, but for a team to work to its optimum level, we need people who are not like us, so the whole is far greater than the sum of the parts. Map your team and get them collaborating.

Creating harmony

ISTJs deal with conflict in their unique way. Getting team members to understand the differences, where the potential areas of conflict might be and, more importantly, showing them how they can quickly overcome them is key to team success. Map your team and get them collaborating.

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

The INTP is very independent, deep and private yet can at times seem totally outspoken because of their directness of communication and economy of words speaking only when there is something to say.

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

INTPs find emotion difficult as they are at heart logical, analytical and objective with no time for anything they see as 'fanciful.' They will not be motivated by someone saying, 'please,' or by emotional pleading.

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

The INTP will find it difficult to share their feelings, although they will be blunt and outspoken regarding their thoughts. In moments of single-minded concentration, the INTP will appear aloof and detached.

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

Sceptical and difficult to know the INTP is wary of close emotional involvement as emotions tends to be slightly outside their own life-space and if someone gets too close too soon they close down.

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.

Personal development

INTPs require a specific approach to being managed, motivated and developed, so that they are best able to contribute to the wider team. To find out how best to develop different personalities take a look at our development tool.
