My experience is similar to the SDAM described in the post. Indeed factual information, or things that are linked to locations are easy to access, yet more arbitrary information like "That one restaurant is named Fleep Burger" or "That person I met a while ago is named Bert" completely escape me.
I do feel like it's a major disadvantage. I often have to act the part when people remenisce about important shared experiences that I was involved with.
Luckily it does tend to only come rushing back when they tell me "Ah yes, it was in the mountain range with the red cabin", but that's usually past the point where I've already made a fool of myself
I've always attributed this to feeling that I truly don't care about some moments or scraps of information. Holding onto them is an entirely pointless chore for the mind, so we forget them by default. Mapping of physical space must be a very different form of memory, however. This doesn't seem to degrade very much over decades and decades of time.
