According to an article in the Huffington Post last year, messy people are actually productive geniuses. I have always been a messy person, so does that mean I'm a genius? On the other end of the spectrum, researchers at Princeton University conducted a study a few years back that found that physical clutter prevents your ability to focus. So which is it?
Many of the professors I worked with in the past were messy for the most part. In some of their offices, I had to climb over boxes of unorganized papers and books to eventually arrive at an actual chair I could sit on. Still there were others that managed to keep their "mess" at a moderate level. I've never really entered an office of an academic that was completely uncluttered and pristine. However, this could possibly change with more and more professors relying on the cloud for document storage and utilizing ebooks for their texts.
For now, I'll stick to staying messy.
