This is the book in pdf format that much of this info has come from. I did not read all of the studies associated and am not a licensed practitioner of the mbti, only an observer that is familiar with a lot of its workings and understandings. Most, if not all of the things I talk about and explain are only my own understandings of the model and, for sure, do come from logical principled understandings gathered from this and other sources, but are not official points of view of the author of this book, nor any licensed mbti practictioner that I am currently aware of. Enjoy the book: it is free to read and is in the public domain last time I checked. If I, or anyone else has found that this is changed, please let me know either through twitter @beyondmindz or through sending me a voice message on anchor and I will get back to you as soon as I can. http://www.oddlydevelopedtypes.com/files/The%20Secret%20Lives%20of%20INTPs.pdf
