Do you (INTps) have naturally adept, highly capable memories, or do you need to work hard to absorb and memorize facts/ideas/etc.? If the latter is true, do you undertake the effort because you believe it's your duty to memorize and understand facts in order to arrive at the truth, or at least the most effective way to act? Do you do it because you find it enjoyable? Or is it something else altogether?
I know that I'm easily able to remember facts if they relate to something important or personally significant to me (most of my "facts" are tidbits about people I know and care about), but otherwise I have to spend lots of time memorizing them before they enter into my long-term memory. I'm more of a generalizer as opposed to a particularizer (not a word, I realize). It's an arduous and ungratifying process, in my experience, and I marvel at anyone else's ability to do this.
