Intelligent people have messy houses, how true is this?

My house is cluttered, not messy.

I pick up dirty clothes, I put dirty dishes in the sink, garbage goes in trash cans, empty cans go in recycling. Nothing laying around my house is “unclean” rotting or dirty. A box of dishes I was going through a month ago that’s still on my kitchen table isn’t dirty, or messy. It’s cluttered.
