ENTPs value progress and change, both in their personal lives and in the world as a whole. The idea of a static, unchanging life -- appealing to some SJs -- is abhorrent to an ENTP. ENTPs are always seeking out new experiences, new ideas, and new achievements. While other types may worry that the world is changing too fast, ENTPs are more likely to be frustrated that the world isn't changing fast enough -- in the direction they want it to move.
Like other NTs, ENTPs tend to have a rational, empirical view of the world and often have a strong and early interest in science and technology -- but this worldview and these interests are expressed differently in each of the types.
While an INTP may be content to design a system or even just prove it is possible to design a system -- ENTPs want to design and build the system and see it working with their own eyes. In this way, they resemble INTJs in their goals -- but not in their approach toward achieving those goals. INTJs tend to work carefully and methodically with a detailed plan of action -- ENTPs are more likely to have bursts of inspiration that are translated into reality through intermittent periods of extremely intense activity.
ENTPs tend to be sociable -- they enjoy interacting with interesting people and doing interesting things with others. The key word is "interesting". ENTPs have a low boredom threshold, and unlike EF-types, they have little desire to be around other people simply for the sake of being around other people.
More than other NTs, ENTPs value intense experiences -- including emotional experiences -- and are less likely than other NTs to attempt to suppress their emotions. When ENTPs are up, they're on top of the world, facing unlimited possibilities, unbounded horizons, and an exhilarating future. When ENTPs are down, the universe lacks any redeeming qualities, whatsoever.
ENTPs are risk-takers -- flying, skydiving, scuba diving, hang gliding, mountain climbing, and fast cars all have a strong appeal for ENTPs. Unlike STP risk-takers, however, ENTPs are less likely to become experts in a particular activity, and more likely to sample a wide variety of different experiences.
ENTPs have little respect for rules that fail to serve a useful purpose. Rules that significantly inhibit the ability to get things done will be changed, finessed, or simply ignored.
While ENTPs value their personal relationships, they find it easier than some other types (in particular, NFs and SFJs) to leave those relationships behind. An ESFJ, for example, might be terrified by the thought of leaving all of their friends behind and moving alone to a new city. An ENTP in the same situation may miss those friends, but at the same time be looking forward to the new people, new places, new experiences, and new opportunities they may find in their new environment.
ENTPs are usually verbally as well as cerebrally quick, and generally love to argue--both for its own sake, and to show off their often-impressive skills. They tend to have a perverse sense of humor as well, and enjoy playing devil's advocate. They sometimes confuse, even inadvertently hurt, 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. This can take the form of getting found out at "sharp practice"--ENTPs have been known to cut corners without regard to the rules if it's expedient -- or simply in the collapse of an over-ambitious juggling act. Both at work and at home, ENTPs are very fond of "toys"--physical or intellectual, the more sophisticated the better. They tend to tire of these quickly, however, and move on to new ones.
ENTPs are basically optimists, but in spite of this (perhaps because of it?), they tend to become extremely petulant about small setbacks and inconveniences. (Major setbacks they tend to 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. However, they do tend to be extremely genial, if not charming, when not being harassed by life in general.
In terms of their relationships with others, ENTPs are capable of bonding very closely and, initially, suddenly, with their loved ones. Some appear to be deceptively offhand with their nearest and dearest; others are so demon- strative that they succeed in shocking co-workers who've only seen their professional side. ENTPs are also good at acquiring friends who are as clever and entertaining as they are. Aside from those two areas, ENTPs tend to be oblivious of the rest of humanity, except as an audience -- good, bad, or potential.
