Portrait of the
Rational Inventor ENTP


"It can't be done" is a challenge to an Inventor and elicits a reaction of "I can do it." These individuals have faith in their ability to come up with solutions to problems, and they display an extraordinary drive for rising to the demands of even the most impossible situations. They are imaginative, and think "outside-the-box" fixing their eyes on possibilities. They are continuously devising new and intriguing ideas to get others involved in learning. Inventors are great leaders of innovative projects that test their ingenuity.


Inventors have an entrepreneurial spirit, always prospecting for the new idea. As they prospect, all that is necessary is a rough draft of the vision or strategy to feel confident and ready to proceed into action. In the spur-of-the-moment, they are able to seize the opportunity in front of them while simultaneously being able to see the wider perspective. For Inventors, big risks equals big rewards; they would much rather go for it and fail, then play it safe to only make incremental progress.


The trademark characteristic of Inventors is that they build prototypes that work to make systems more efficient. These individuals get such a kick out of inventing that they really never stop exercising their creative talent. Inventors are interested in building the replicable model. These experimental individuals are often deeply engrossed in their work; their curiosity is the root of their persistence and keeps them focused until they figure out the solution.


Inventors are intensely curious and continuously probe for possibilities, especially concerning complex problems. Such curiosity can be inspiring to others, who find themselves admiring their insatiable hunger for know-how. They seek to understand the unknown, and as a result, they tend to have all sorts of hobbies and tend to be experts in unexpected areas. Their curiosity about themselves and their own capabilities extend to a broader quest to understand others.


Inventors are the most reluctant of all the types to do things in a particular manner just because that is the way things have always been done. They characteristically have an eye out for a better way, always on the lookout for new projects, new activities, and new procedures. They are confident in the value of their approaches and display a charming apacity to ignore the standard, the traditional, and the authoritative. As a result of their pragmatic style, they often bring fresh, new approaches to their work and their lives.


Inventors are innately collaborative. They often have lively discussions filled with interesting ideas. Their open-mindedness makes them the natural brainstormer, as they focus on the sharing of concepts. For these individuals collaboration is about synergizing for exponential results. They are keen listeners while at the same time being ruthless and rigorous about analyzing, debating, and integrating ideas and concepts. This sort of dynamic exchange is the essence of their open-mindedness.
