ISTJ 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.

Risk averse they prefer the known, and prefer facts to concepts.

INFP Meaning, harmony and personal values are at the heart of the INFP. It is essential to the INFP that their beliefs and actions are totally in sync.

Deep and private, they do not like being boxed in or constrained by rules.

ISTJ 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.

INFP The INFP will tend to prefer a less visible role as their strengths are working from the back and supporting others, using their insight and wisdom and lack of ego rather than being the leader.

ISTJ 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.

INFP Flexible and spontaneous INFPs will need their space and freedom to work their way. They dislike routine and need meaning to be part of something special, and they will be loyal and diligent and productive.

ISTJ 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.

INFP Spontaneous and creative the INFP inhabits the internal world of imagination and is not bound by traditions. The ideal world is one where they can immerse totally in interesting and meaningful tasks.

INFP For a type so caring and gentle there is a surprisingly crusading side to the INFP. When a personal value is trodden on, the INFP can become uncharacteristically outspoken and champion of the cause.

ISTJ 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.

INFP The INFP does not like conflict and will seek to be the one who brings harmony, diffusing tension and seeing things from the other person’s perspective, excellent supporters and empathetic friends.

ISTJ 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?

INFP Conflict, aggression or even extended people interaction will sap the energy of the INFP who will need to disappear back into their own inner sanctum, reflect deeply on how it made them feel and recharge.

ISTJ 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.

ISTJ 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.

INFP INFPs are incredibly emotional, indeed they can actually feel what others are feeling and this can even stay with them. They are tuned in and insightful and they are happy to deal with the emotions of others.

ISTJ 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.

INFP The INFP will often display their reactions to their feelings, rather than their feelings, and may bottle things up which then leak out at strange moments thus adding to the 'difficult to understand' image.

ISTJ 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.
