I've been around professors for many years. Many of them have filthy offices and seem to take pride in their slovenly ways. They are horrified at the thought of having neatly combed hair. (Liberal) popular culture picked up on this a long time ago and continues to celebrate personal disorderliness. (According to research, a disregard for personal hygiene is a sign of mental disorder).
General Social Survey interviewers ask their questions in people's homes. In 2000, they also recorded how clean the respondent's place was. The top graphs summarizes cleanliness by political views. Conservatives keep a tightier house.
In case you suspect that this is due to the messiness of the homes of poor minorities, look at the bottom graph for whites only. The pattern remains.
