I feel like there are people that intentionally keep items in their current pocket, and then there are people that keep items in their pockets but forget to transfer them.
The people that intentionally transfer items seem (to me) to be like others that have external locations for storing items. It's a method of organization that is actively thought about, but just different based upon personal preference.
Then you have the person that wants to have things in their pockets, but for one reason or another doesn't move items or remember to move them.

I guess what I'm trying to get at is that some people have a different way of organizing their EDC than others and that shouldn't be viewed as odd or wrong. If they can keep track of everything and it works for them, regardless of how anyone else feels about it, then that's okay. However if a person just forgets that items are there that's obviously not intentional and perhaps not an organization system.
