The reason I ask is that I have met three entps who can do this-it may be that they were focusing on the content at that moment thus it stuck.
Kind of makes sense, when you think about it that way that "what was being said" is actually external and ENTPs are more focused on the outside... Ok, I just lost what I wanted to say, even though I did have a good insight. Darn. Happens so often
I tend to remember the idea of the conversation. The reason and the subject. But literal words and sentences? Why would I bother remembering that.
That's the thing - I have never "done" anything to remember something word-to-word, I just remember. Vividly. As I said - if I do remember, I remember the whole "movie", i.e. not only words, but also the tone of the voice, what the person did, how he looked like, what was his emotion, where he said that, how was the light like in the room etc etc etc.
If I'm trying to remember something exactly, I use mnemotechniques as well sometimes, when needed, but that's a totally different story then. If I use some kind of techniques, I'm actually sort of half-consciously re-producing what was being said, done or smth from the connections I had made. If I "just" remember, I don't have to do anything to get the memory back. It's much faster and, also, I'm much more certain of the memory, there is just no doubt at all.
Now I'm thinking what ARE the things I remember so well... I'll let you know
