INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.’

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.

INTP 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.

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.
