Your political affiliation
Conservatives tend to be neatniks with brightly lit, organized rooms, according to a study in the journal Political Psychology. They have more sports paraphernalia, cleaning supplies, and American flags than liberals do. Liberals’ homes, on the other hand, are more likely to be cluttered and have a variety of books, music, maps, and colors. Psychologists say conservatives tend to be traditional, reflected in conventional decor, while liberals may be less conscientious and more open-minded.

What you watch on TV
Internet-connected televisions can collect data on everything you’re watching and sell it to advertisers—and many are set up to do it by default. (To keep your information private, turn off data sharing in your TV settings.)
Whom you live with
Your dirt reveals whether there are more men or women in the household (the sexes shed different types of bacteria). By examining the fungi in your dust, scientists can also predict where in the country you live, down to about a 150-mile range.
