Ridiculously amazing when something interests me (as I'd guess for most people).
Otherwise, meh.
Although, I can remember a lot of weird details about things and people, without conscious choice - i.e., beyond-my-control selective memory.
Like exactly where a piece of info is located in a book, its paragraph and page number [and usually, most notably, I remember if it appeared on the left side, or right side of the book]. Or, like when my ex liked to play with my memory by asking me random questions, like, "What was the number on the shirt I was wearing when we went out for Italian last Thursday?" and other such useless things. These things comes to me as flashes of static mental images - as if I'm literally there, in that moment, again. It's overwhelming in its clarity. However, it's usually all or nothing, so if I get a prompt which triggers a mental image to flash before me, I know with 100% certainty. Sans mental image, I got nothing. I have a very hard time consciously trying to recall something just beyond my reach. I am very prompt/trigger dependent. Give me the right clue/cue, and I can access everything I know surrounding the topic, in an instant.
Where it does help me is in figuring out when people "lie", as something they tell me currently will send red flags all over my head, just because some detail about them, from a past interaction, in my memory is saying, "wait, if X detail is true, than what he is saying currently is not consistent!" I may not have clear and easy access to that past detail, but, something in me KNOWS that something is off. RED FLAG! :17026:
