Randomizing facts (or pictures) in order to draw new information from the same details that you've been staring at for a long time. It's often used by detectives, when they've come up against a wall of some sort.
The BBC's Luther used this at one point, and named the practice, but I am having no luck finding that point in an episode as yet. Google isn't much help either; searching with any form of "random facts" in the search phrase ends up giving me pages full of just that.
(I'm sorry, I have no idea what to tag this as, since I couldn't find a tag for just words.)
