ISTJs are often called inspectors. They have a keen sense of right and wrong, especially in their area of interest and/or responsibility. They are noted for devotion to duty. Punctuality is a watchword of the ISTJ. The secretary, clerk, or business(wo)man by whom others set their clocks is likely to be an ISTJ.

As do other Introverted Thinkers, ISTJs often give the initial impression of being aloof and perhaps somewhat cold. Effusive expression of emotional warmth is not something that ISTJs do without considerable energy loss.

ISTJs are most at home with "just the facts, Ma'am." They seem to perform at highest efficiency when employing a step-by-step approach. Once a new procedure has proven itself (i.e., has been shown "to work,") the ISTJ can be depended upon to carry it through, even at the expense of their own health.

ISTJs are easily frustrated by the inconsistencies of others, especially when the second parties don't keep their commitments. But they usually keep their feelings to themselves unless they are asked. And when asked, they don't mince words. Truth wins out over tact. The grim determination of the ISTJ vindicates itself in officiation of sports events, judiciary functions, or an other situation which requires making tough calls and sticking to them.

Their SJ orientation draws the ISTJ into the service of established institutions. Home, social clubs, government, schools, the military, churches -- these are the bastions of the SJ. "We've always done it this way" is often reason enough for many ISTJs. Threats to time-honored traditions or established organizations (e.g., a "run" on the bank) are the undoing of SJs, and are to be fought at all costs.

ENFPs are both "idea"-people and "people"-people, who see everyone and everything as part of a cosmic whole. They want to both help and to be liked and admired by other people, on both an individual and a humanitarian level. This is rarely a problem for the ENFP, as they are outgoing and warm, and genuinely like people. Some ENFPs have a great deal of zany charm, which can ingratiate them to more stodgy types in spite of their unconventionality.

ENFPs often have strong, if sometimes surprising, values and viewpoints. They tend to try to use their social skills and contacts to persuade others gently (though enthusiastically) of the rightness of these views; this sometimes results in the ENFP neglecting their nearest and dearest while caught up their efforts to change the world.

ENFPs can be the warmest, kindest, and most sympathetic of mates; affectionate, demonstrative, and spontaneous. Many in relationships with an ENFP literally say, "They light up my life." But there is usually a trade-off: the partner must be willing to deal with the practical and financial aspects of the relationship, and the ENFP must be allowed the freedom to follow their latest path, whatever that entails.

For some ENFPs, relationships can be seriously tested by their short attention spans and emotional needs. They are easily intrigued and distracted by new friends and acquaintances, forgetting their older and more familiar emotional ties for long stretches at a time. And the less mature ENFP may need to feel they’re the constant center of attention, to confirm their image of themselves as a wonderful and fascinating person.

In the workplace, ENFPs are pleasant and friendly, and interact in a positive and creative manner with both their co-workers and the public. ENFPs are also a major asset in brainstorming sessions; follow-through on projects can be a problem, however. ENFPs do get distracted, especially if another interesting issue comes along. They also tend towards procrastination, and dislike performing small, uninteresting tasks. ENFPs are most productive when working in a group with a few Js to handle the details and the deadlines.

ENFPs are friendly folks. Most are really enjoyable people. Some of the most soft-hearted people are ENFPs.

"Clever" is the word that perhaps describes ENTPs best. The professor who juggles half a dozen ideas for research papers and grant proposals in his mind while giving a highly entertaining lecture on an abstruse subject is a classic example of the type. So is the stand-up comedian whose lampoons are both funny and incisively accurate.

ENTPs are usually verbally as well as cerebrally quick, and generally love to argue--both for its own sake, and to show off their debating skills. ENTPs tend to have a perverse sense of humor as well, and enjoy playing devil's advocate. This sometimes confuses, even angers, those who don't understand or accept the concept of argument as a sport.

ENTPs are as innovative and ingenious at problem-solving as they are at verbal gymnastics; on occasion, however, they manage to outsmart themselves. ENTPs can be prone to "sharp practice" – especially cutting corners without regard to the rules if it's expedient – or, their juggling acts may simply be so over-ambitious they collapse.

Both at work and at home, ENTPs are very fond of "toys" -- physical or intellectual, the more sophisticated the better. Once these have been "solved" or become too familiar, however, they’ll be replaced with new ones.

ENTPs are basically optimists, but in spite of this (perhaps because of it?), they can become petulant about small setbacks and inconveniences. (Major setbacks they regard as challenges, and tackle with determination.) ENTPs have little patience with those they consider wrongheaded or unintelligent, and show little restraint in demonstrating this. In general, however, they are genial, even charming, when not being harassed by life.

In terms of their relationships with others, ENTPs are capable of bonding very closely and suddenly with their loved ones. Some appear deceptively offhand with their nearest and dearest; others are so demonstrative that they succeed in shocking co-workers who've only seen their professional side. ENTPs are also quick to spot a kindred spirit, and good at acquiring friends of similar temperament and interests.

ENTPs may sometimes give the impression of being largely oblivious to the rest of humanity except as an audience: good, bad, or potential. In general this is unfair – but it can be difficult to get an ENTP’s attention when they’re not immediately aware of you, especially for an Introvert.

The best approach in communicating with an ENTP is to be straightforward. No games – they’ll win. No "pulling rank" – they’ll just want to put you in your place. No apologies – you’ll undermine yourself. Try "I need/want to talk to you."
