Tag ideas

I'd like to group the following books together and I can't think of a good tag to use: Blink, The Prince, The Peter Principal, Deep Survival, and Freakonomics. Those are the ones off the top of my head, though How the Mind Works would go in if I owned it. Any help would be appreciated. On Thinking perhaps?

"cognition" or "cognitive science" fits all but The Prince...

"practical psychology"?

I'll just piggyback my question here rather than begin a new thread.
I'm looking for a tag phrase used to describe an intrusive narrator. I may use that exact phrase, but I'd like to know what others have used so that I can search for more of the same.
I see that two members have used that phrase, for two books by Salman Rushdie and one by Pseudonymous Bosch. That's not my direction.
I just listened to a mid-adolescent (not yet YA) book titled Horton Halfpott by Tom Anglberger. The reader did it great justice. The narrator is omniscent, and addressing the reader, offers his own opinion of characters/situations and tells when we'll next meet a character. It's very charmingly done.

ps:Edna Ferber and Jane Austen are other employers of the technique.

According to my Handbook to Literature in "an omniscient author point-of-view, the author himself (sic - I have an old edition) acts self-consciously as narrator, recounting the story and freely commenting on it." So:

omniscient narrator

or if you want to be sure to get your point across

omniscient narrrator (intrusive)
