Oh. This explains patrons.

So a scientist has determined the “personalities” of every state in the U.S.

According to the interactive diagram, Michiganians are only middle-of-the-road in terms of their openness.  That can’t possible relate to library patrons.  Any librarian will tell you that Michigan library patrons are all too willing to share their medical history, political opinion, assessment of your job skills, religious beliefs, favorite cupcake recipe, child-rearing advice, sexual escapades, dental hygiene habits, and just about anything else you can fathom (and many things you cannot).

I think it’s a cool little study.  Worth looking at for sure.
