strengths

• great analysts and abstract thinkers - people with the INTP personality type view the world as a big, complex machine, and recognize that as with any machine, all parts are interrelated. INTPs excel in analyzing these connections, seeing how seemingly unrelated factors tie in with each other in ways that bewilder most other personality types.
• imaginative and original - these connections are the product of an unrelenting imagination - INTP's ideas may seem counter-intuitive at a glance, and may never even see the light of day, but they will always prove remarkable innovations.
• open minded - INTPs couldn't make these connections if they thought they knew it all - they are highly receptive to alternate theories, so long as they're supported by logic and facts. in more subjective matters like social norms and traditions, INTPs are usually fairly liberal, with a "none of my business" sort of attitude - peoples' ideas are what matter.
• objective - INTPs' analysis, creativity, and open-mindedness aren't the tools of some quest for ideology or emotional validation. rather, it's as though people with the INTP personality type are a conduit for the truths around them, so far as they can be expressed, and they are proud of this role as theoretical mediator.
• honest and straightforward - to know one thing and say another would be terribly disingenuous - INTPs don't often go around intentionally hurting feelings, but they believe that truth is the most important factor, and they expect that to be appreciated and reciprocated.
