Being an INFP, I think I've come to understand how the INFP's hidden agenda works. I'm real touchy about my ability in subjects like math and always remember when taking statistics class not feeling secure until I understood why the equations were true (an understanding which didn't always come even though I could memorize them by rote.) I also fear losing my ability to think or be logical which I think relates to an insecurity in that area. I always want to test myself with the various IQ puzzle books I have but never actually get around to doing it probably because of my hidden agenda. It's almost like I'm afraid I won't understand something. Well, hopefully that makes a little sense.
