ISTJ
The Inspector
Introverted, Sensing, Thinking, Judging
Serious-minded, individualistic and thorough, the ISTJ personality types like to plan, schedule and drive through to completion, in a logical linear sequence. Any deviation from the plan would be questioned and may take some convincing of its merits. The ISTJ is essentially the engine room, the behind-the-scenes worker making it happen. Concentration, willpower and persistence epitomises the ISTJ approach to work and to life and they will begin at the beginning and end at the. Spontaneity and flexibility are less important to the ISTJ. Conservative and risk-averse ISTJs excel when it needs a steady hand and they are unlikely to ever drop the ball.
ISTJ Characteristics
The ISTJ is the behind-the-scenes worker making things happen. Their sense of duty and loyalty means that they will rarely be happy in the front line, preferring to be in the back room making it all happen. The ISTJ is the sensible, ‘prefect-type’ character, who wants to get it right and 'do good.' Their value to the team is protection, from mistakes, from omissions, from self-delusion and from going off-track. The ISTJ loves seeing things come to fruition. Ideas, complexity and imagination are of value only if they lead to a practical end result. An ISTJ needs to be clear on what is expected, and then will plan and work with consistent and steady energy towards completion. Their opinions will be slowly arrived-at and, consequently well-thought-through, tried and tested. The ISTJ is not prone to bursts of emotion, flying by the seat of their pants nor will they thrive in a chaotic environment, unless they have the opportunity to formalise it and make it non-chaotic.
Serious-minded, individualistic and thorough, the ISTJ may focus so much on the task that they can forget the needs of others, including themselves. ISTJs like to plan, schedule and drive through to completion, in a logical linear sequence. Any deviation from the plan would be questioned and the ISTJ may take some convincing of its merits. An ISTJ can be trusted to complete, to work hard and play by the rules. However, they may not always articulate how they are feeling or even how things are progressing. The ISTJ plans the work and works the plan, so why should there be any need for up-dates. They naturally tune into the actualities and specifics of life and thus they will be reliable, loyal and work with existing, known facts and data. Conscientious, hardworking and serious about their undertakings ISTJs are built for attrition, to work tirelessly in achieving the agreed goals. The ISTJ may not have been the one to set the goals but they will make sure they are met - to the letter, working methodically, carefully and taking it very personally. Everything is taken literally (with no irony) and they pride themselves on being careful and accurate about ‘the facts.’ ISTJs are built to execute, exactly as agreed.
Quiet and thoughtful, the ISTJ work best when they are clear on what is expected and then allowed to get on with it without interruption or interference from others, preferably in a familiar way in familiar surroundings. The ISTJ does not like being thrown in at the deep-end and they have to feel that whatever they are being asked to do makes logical sense. The new, the untried worries the ISTJ as they rely instinctively on experience and prefer the known and the traditional and, as they learn best through doing so any activity with which they have no direct first-hand experience will cause a wariness and mistrust initially. Sure, the ISTJ can change but they need to see a logical reason for doing so, and they’ll need to think it through. Anything perceived as woolly will not compute. Conservative, risk-averse and methodical ISTJs come into their own when it needs a steady hand and abject attention to detail. And they are unlikely to ever drop the ball. The ISTJ will not be prone to say: ‘let’s give it a whirl.’
Others may see them as slightly cold and impersonal, possibly even uncaring. However, their decisions are based on what makes the most logical sense and as such this can mean the feelings of others may not necessarily be factored into this process. The ISTJ will then systematically carry out the task diligently and to the letter, which can make them appear inflexible, but this is simply a sign of the seriousness with which they embrace responsibility.
ISTJs will begin at the beginning and end at the end, no deviations. They have a keen sense of what’s right and wrong, are known for dedication to duty, and so doing things right, being punctual, doing what they say they’ll do, are the values they live by.
ISTJ Careers
Linking ‘type’ and ‘careers’ would be easy if it was just about listing specific jobs that perfectly fit specific personalities. However in truth it is more difficult than that as ignores other, more important issues, such as the organisation, the values and the culture, which are far better determinants of suitability than a job title. Also individual jobs vary widely from industry to industry, organisation to organisation and person to person. Therefore our focus on ‘type’ and ‘careers’ will be far more on you: your personality, your aptitudes, interests, likes, strengths and weaknesses and then matching these to the sorts of environments, cultures and norms within organisations that will allow you, given your character, to thrive grow and flourish. We spend a lot of our time at work and so it is important to get these issues right or we could spend a lot of working time unhappy, unproductive and unfulfilled.
Strengths
The ISTJ will set great store by their strong work ethic, moving step-by-step towards and agreed conclusion. The do not like working in chaos but to be fair if there is a lack of a plan the ISTJ will create one. The ISTJ is hardworking, organised and likes things done properly, having high standards. They prefer clarity and if there is none, again they will create it. This means they will expect, and set, tangible goals that they will work steadily and methodically towards with no shortcuts. They are efficient, reliable and although they may take time to understand what is required, this is simply so that they grasp all the facts to ensure they are clear and will not get it wrong, then they are best left alone to complete, on time. The ISTJ prefers using their own experience and ‘the known’ as they store it all in their pristine filing cabinets inside their heads and will apply these to all activities to bring consistency and a drive for closure, which is inexorable. They are independent, happy to work for long periods on their own, indeed they prefer it, immersing themselves in the facts and tangible details and they will follow what has been agreed to the letter. The ISTJ is detailed, practical, factual, sensible and responsible and they take these responsibilities very seriously.
Weaknesses
As with all personality types our strengths can, in some circumstances, be our weaknesses. The ISTJ is assiduous and detailed and so they tend not to like and surprises or even change unless the rationale is clear. Any changes to ‘the plan’ can throw them as they get seriously locked into their drive for closure as so they prefer stasis and predictability to an ever-changing landscape as it can potential blow their carefully laid out plans off course. This trait also means they tend not to be innovators, preferring activities that they have tangible experiences with, so they may not come up with, or indeed even see new possibilities or opportunities. The ISTJ prefers to take in the specifics, the ‘here and now’ and so may not be looking over the horizon as their focus tends to be on ‘what is’ rather than ‘what could be.’ The new and untried worry the ISTJ as they prefer things to be rigour tested so that is becomes part of the ‘known’ world rather than an unpredictable world, which makes them uneasy. Their desire to follow through on what has been agreed, a superb trait at times, can also make them slightly judgemental of others who take a different or more circuitous route and their factualness means they may at times project a little harsh. The ISTJ also tends to dislike noise or bustle, preferring a quieter, more focused atmosphere.
Best Work Environments
Risk-averse, traditional, factual and detailed the ISTJ is best suited to more established, stable and traditional organisations that value hard work, attention to detail and adherence to known rules and protocols. Wherever tradition rules and the credo is, ‘we've always done it this way,’ is where the ISTJ will excel as their forte is bringing order to chaos, bringing process to creativity and these are the sorts of environments where an ISTJ will thrive, flourish and grow. Their traditional nature and desire for clarity and factual guidance means the ISTJ will fit best where the norms are clear, the culture is performance driven and where there is a place for everything and everything is in its place. Deviation from the norm is not for the ISTJ. They prefer working with facts, details and the known, where the product or service is tangible rather than conceptual and there are clear lines of responsibility and a planning process. They do not like to ‘wing it’ or take risks without being in possession of the facts and having thought things through so that they are clear; ambiguity is the enemy of the ISTJ.
Worst Work Environments
The ISTJ will be less well suited to environments which are noisy, or they have little room or space to work quietly and alone. The ISTJ draws their energy from within and so boisterous environments with lots going on will distract them from the task, and the ISTJ does not like to be distracted. This does not mean the ISTJ cannot, or does not want to, have fun. It is just that in the structured, boxed up world of the ISTJ ‘fun’ will have time apportioned to it and when it’s over, it’s over. Their need for structure and predictability means the ISTJ prefers the known and so any surprises or an environment, which is based on flexibility, and the ground moving will not be the right one for them. The ISTJ feels safer with processes and protocols as this structure provides the basis and impetus for them to drive forward for closure, sticking to the plan and delivering on time and as agreed. A fast paced environment, an ever-changing landscape where the norms are unclear or there is ambiguity will make the ISTJ feel insecure and this will remove their ability to have the clarity and stability they require to succeed.
Best Careers
The ISTJ needs stability and security and so will not thrive in careers where there is risk and uncertainty. Of course the ISTJ will create stability and process where there is none, but roles, which actually require complete flexibility or which require constant change, will not be for them. Production, Health and Safety, Auditing, Administration, Process Control type roles will all suit the ISTJ as they are primarily ‘doing’ roles with less emphasis on people and more emphasis on facts and the exact way of doing things.
ISTJ Work
The ISTJ personality type value at work is protection - from mistakes, from omissions, from self-delusion and from going off-track. In a team situation, the ISTJ will bring order, clarity, organisation and planning. Although introverted and so not the most vocal member of the team, the ISTJ will seek to make sure the team is best placed to move towards a 'known' conclusion in a thorough, planned and detailed way without going off at tangents.
Consummate planners, ISTJs love seeing things come to fruition. Ideas, complexity and imagination are of value only if they lead to a practical end result. The ISTJ will be great at spotting flaws in arguments, missed details and preventing the team haring off in the wrong direction. They seem to have a built-in immunity from getting excited and so will bring a strong sense of reality and factualness to the team which may not be inspiring but will add so much value in the longer term in ensuring agreements are adhered to and things progress according to the plan.
Sure they may not be the one coming up with the ideas or keeping the momentum going but their role is primarily protector and in that they will be invaluable to the team. They excel at analysing problems and evaluating ideas and suggestions, so the team is better placed to make balanced decisions. In a team environment the ISTJ will be unemotional and factual. They may not be motivational or strongly vocal, but they are superb at analysing problems and evaluating ideas and suggestions and weighing up the pro’s and con’s of options. Teams will be better placed to make balanced decisions with an ISTJ there.
ISTJs bring a strong sense of planning, agreeing objectives and working steadily towards closure. They will excel 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. Best managed by clear tasks, ISTJs need time to fully understand what is expected then let them get on, working with consistent steady energy and not micro managed. ISTJs have and incredible eye for detail, they will want to slowly assimilate information and be sure of their facts before moving forward and this will be as per the plan. ISTJs are more factual than creative and their value is exactly that: ensuring that was has been agreed is delivered exactly as agreed.
ISTJ Relationships
ISTJs often struggle with the emotions of other people as they are more factual logical and of course, emotions are more irrational and so they are difficult to quantify or put in a box. This means that when confronted with emotions, an ISTJ almost has to translate them from feelings into factual, concrete language that they can understand, something tangible. ISTJs are often seen as a little cold and aloof, even that they don’t care, but this is not the case, it’s simply because they are formal, serious, factual individuals who need to process information. Also, too much ‘people time’ will run their energy levels down and they will need some quiet, thoughtful time by themselves, to recharge. This is something that extraverted types can find difficult and it can alienate ISTJs from those who want to build a relationship, but too much noise and lots going on will do their heads in.
ISTJs are extremely formal and so any personal information will emerge slowly over time and in stages as ISTJs are extremely deep and private individuals. They don’t like to share their feelings until they have built a level of trust with other people and feel they have the measure of them. However, because they don’t easily share their feelings, that doesn’t mean they don’t express their thoughts, if invited. Ask an ISTJ if your dress is a good fit, and you will get a very honest, and very factual answer, possibly one you didn’t want to hear! Their intense focus on the task, means they may forget the ‘niceties’ of relationships, even to speak, and even forget to factor their own needs, so focused are they on what they’re doing.
Dutiful and formal, an ISTJ will always stick to their word and do what they say they will do, exactly as stated, and they prefer it when other people do. Their view is ‘why say you’ll do something and then not deliver?’ This is because delivering and consistency is what ISTJs are about, it is what they value and so they will value that in others. They have a very clear sense of ‘right and wrong,’ ‘good and bad,’ and can be quite binary and purist about this.
ISTJs do not like the emotionality or noise of verbal conflict and they will prefer a more formal approach, and going, as they would say, “through the proper channels.” Trying to challenge, especially in front of others, will see the ISTJ close down, like the “shields” for the Batmobile in the 1989 first Batman movie, and they’ll become very insular.
