Okay, so you're not talking about the psychology that makes The Container Store profitable then... But something ambiguously broader.

I'm not a psychologist -- this may be so broad is to be a philosophy question instead -- but humans like simplification and stories.

Some of that may be thriftiness with biologically-expensive brainpower, and some of it may be tied to our core mechanisms for understanding the world with cause and effect.
