ISTP The ISTP moves seamlessly from quiet bystander to being at the heart of solving problems then back again. They get an incredible buzz from difficult situations using their incredible store of knowledge, grasp of facts and practical nature to jump in and fix things but when it’s over, will get bored and withdraw once again to the sidelines, waiting for the next problem to arise.

ISFJ ISFJs are quiet, and often understated people-centric doers. Conscientious and hardworking, they are loyal and dedicated to people and organisations, and they take their responsibilities very seriously. They have an incredible store of knowledge and superb memory used to support people and solve problems. Shunning the limelight the ISFJ is often the one who quietly make it all happen.

ISTP The ISTP will bring their vast store of knowledge and experience to bear on the team, showing great determination but their low boredom threshold means once they have sorted the problem they withdraw.

ISFJ The ISFJ will bring order, clarity, organisation and planning. Although not the most vocal member of the team, the ISFJ will make sure the team moves towards a 'known' conclusion in a planned way.

ISTP ISTPs are great in a crisis as they love the whole buzz and action of problems and difficulties. They are less good when the going is not tough and not so good at the more sensitive side of leading people.

ISFJ ISFJs are more of the behind the scenes operators rather than being a charismatic leader. Yet their incredible memory, their caring and practical nature and planning ability make them good team leaders.

ISTP ISTPs are extremely independent and will like the freedom to work in short bursts of energy on difficult action oriented practical problems that hold their interest. Routine and steady detail will bore them and they need their space.

ISFJ Ironically, because they prove over and over that they can be relied on for their loyalty, attention to detail and high-quality work they can be taken for granted. Give them clarity and trust, they will deliver.

ISTP Because of their full on or full off nature, ISTPs will either be right at the heart of the detail, surprising others with their vast store of knowledge and data, or if it is boring they will go back to their space.

ISFJ The ISFJ is painstaking, orderly, conscientious and anxious with a superb capacity for follow-through although they have a tendency to worry about the smaller things and a reluctance to ‘let go.’

ISTP ISTPs are essentially practical, preferring the concrete and factual to anything they perceive as woolly or impractical. But when they focus on a problem they can be forensic, coming up with practical solutions.

ISFJ ISFJs have a great memory for facts and superb attention to detail. They will be more factual and practical than overtly creative, motivated by an internal anxiety to ensure the team doesn’t fail.

ISTP ISTPs love difficult situations and they will see conflict as something, like everything else, to be fixed then move on. They do not seek conflict but are impervious to their environment so it goes with the territory.

ISFJ The ISFJ will initially close down on conflict as they prefer harmony and indeed will work hard at creating that. Indeed the ISFJ will be a superb diffuser of conflict but they themselves do not enjoy it.

ISTP Intensely practical the ISTP will only want to get the problem solved or the issue addressed, practically and as quickly as possible. Personal feelings matter only insofar as they relate to what needs to be done.

ISFJ ISFJs are often called ‘the defender’ and this is because they will stand up for what is right and the rights of others. So whilst they may shun conflict personally, they will fight for other people.

ISTP The ISTP tends to be economic with words and a little terse in their communications. This is not rudeness just a desire to get everything resolved and so they will have no problem getting to the point.

ISFJ Naturally more quiet and low key, the ISFJ will be conciliatory and seek consensus preferring to see good in people and they will look to get to a resolution that makes everyone happy.

ISTP As ISTP’s are factual and living for the moment, any conflict will just be a small part of getting the problem fixed (which energises them) and then if it becomes chitchat their energies will deplete. They need action.

ISFJ Altercations and over interaction in general sucks the energy of the ISFJ and so they will need some private ‘me’ time to recharge their batteries and build up their energy levels.

ISTP ISTPs tend to be either full on or full off. They can be passive bystanders until something grabs their interest or a practical problem needs fixing and then they take over, fix it, and withdraw loving the buzz.

ISFJ ISFJs are deep and caring with strong values and these will be held privately until the ISFJ allows people in. What others will perceive is a helpful, supportive, patient and detailed individual who is under the radar. The ISFJ is sociable but doesn’t like the spontaneity of crowds.

ISTP Although friendly the ISTP is more practical and factual and so may not understand emotions. They tend to break things down to constituent parts and do not like anything they see as irrational.

ISFJ The ISFJ is an emotional type, but may struggle at times to deal with these, as they are so private and reflective. It may be possible to deeply offend an ISFJ and not realise it, so private are they.

ISTP The ISTP is quite closed to emotional issues. It does not make them uncaring but sharing feelings or intuiting how others are feeling doesn’t really compute with their scientific nature.

ISFJ Once allowed close the ISFJ will open up but it will take time and they are not naturally forthcoming. This may mean it emerges in small chunks, often off the back of other conversations.

ISTP At their heart ISTPs are thrill seekers and will love to be where the action is. However once they have jumped in and experienced they will tend to go back to being passive and quiet.

ISFJ ISFJs have a strong sense of what is right and wrong and will tend to do what they believe is right, even at the expense of themselves. They really do want to support, care and are generous with their time.
