Researchers think that the condition of our offices and bedrooms says a lot about our political philosophies. Their findings show that people with messy rooms tend to lean left, and conservatives are often neat freaks.

According to a controversial new study, set to be published in The Journal of Political Psychology, the bedrooms and offices of liberals, who are generally thought of as open, tend to be colorful and awash in books about travel, ethnicity, feminism and music, along with music CDs covering folk, classic and modern rock, as well as art supplies, movie tickets and travel memorabilia.

Conservatives, on the other hand, tend to surround themselves with calendars, postage stamps, laundry baskets, irons and sewing materials in their personal spaces, according to the study. Their bedrooms and offices are well-lighted and decorated with sports paraphernalia and flags—especially American ones.
