I can definitely say that I am a mapper and not a packer. But I can also say that I am pretty much _all_ mapper and no packer. This means that it takes me forever to understand a lot of things that presumed packers (or more balanced individuals) would get in a jiffy. This is not intended as a humble brag! For the longest time on some projects I just don't f**ing get it, I start to feel dumb and in way: out of place. The imposter syndrome makes itself heard. It's genuinely uncomfortable.

But then I start to get it and finally do get it. The packers are now "experts" at their acquired knowledge and seem to have a hard time changing opinion where they should.

Back in school I had real problems getting good enough in subjects that required learning pieces of fact that don't quite go together or display some inherent system. My friends didn't. Things that have a system or are "logical" in the wider sense, easy peasy.

EDIT: I would call myself a decently accomplished programmer and engineer at this point after 25 years or so working with it.
