I've searched thesauruses to no avail. I'm hoping to find a more refined way of describing someone as 'disorganized', which to me seems to have a slightly negative connotation. The alternatives I have come across so far seem to be even worse ('chaotic', 'confused' etc.). What I have in mind would be something to conjure up the image of an eccentric scholar, perhaps sort of besieged by books piled on either side in disarray.
The question already posted didn't quite give me what I wanted, since it seemed to be referring to someone who was fond of chaos, not someone who simply can't keep themselves neat. I felt the suggestions given were mostly unflattering as well, which isn't what I'm looking for.
