Very Private and Withdrawn - While INTPs' intellectualism yields many insights into their surroundings, their surroundings are ironically considered an intrusion on their thoughts. This is especially true with people – INTPs are quite shy in social settings. More complicated situations such as parties exacerbate this, but even close friends struggle to get into INTPs' hearts and minds.
Insensitive - Oftentimes INTP personalities get so caught up in their logic that they forget any kind of emotional consideration – they dismiss subjectivity as irrational and tradition as an attempt to bar much-needed progress. Purely emotional situations are often utterly puzzling to INTPs, and their lack of timely sympathy can easily offend.
Absent-minded - When INTPs' interest is captured, their absence goes beyond social matters to include the rest of the physical world. INTPs become forgetful, missing even the obvious if it's unrelated to their current infatuation, and they can even forget their own health, skipping meals and sleep as they muse.
Condescending - Attempts at connecting with others are often worse than INTPs' withdrawal. People with the INTP personality type take pride in their knowledge and rationale, and enjoy sharing their ideas, but in trying to explain how they got from A to B to Z, they can get frustrated, sometimes simplifying things to the point of insult as they struggle to gauge their conversation partners' perspective. The ultimate insult comes as INTPs give up with a dismissive "never mind."
Loathe Rules and Guidelines - These social struggles are partly a product of INTPs' desire to bypass the rules, of social conduct and otherwise. While this attitude helps INTPs' strength of unconventional creativity, it also causes them to reinvent the wheel constantly and to shun security in favor of autonomy in ways that can compromise both.
Second-Guess Themselves - INTPs remain so open to new information that they often never commit to a decision at all. This applies to their own skills as well – INTP personalities know that as they practice, they improve, and any work they do is second-best to what they could do. Unable to settle for this, INTPs sometimes delay their output indefinitely with constant revisions, sometimes even quitting before they ever begin.
