I've noticed that even in homes with a very staid and conservative overall "look", that in the bathroom you will frequently find wall-hangings that evoke mild titillation, or demonstrate humorous scatology, or low-brow humor. Is this a real thing, or just overrepresented in the bathrooms I've seen most often (white, Midwestern, Protestant)? Or is it not a thing at all, and just confirmation bias on my part?
The homes I've visited the most have been Midwestern, white, protestant, and working- or middle-class. For most of my early upbringing they were also rural.
The overall home decor I remember most is very conservative and aspirational: family photos, nature scenes, some cultural object designed to show that one could afford travel. Just... bric-a-brac. Its primary function seemed to be to advertise: "We are clean and respectable people who are (or should be regarded as) middle-class."
But all bets were off in the bathroom. My mother's house was chaste and straight-laced, but she had a dime-store print of Renoir's "The Bathers"
in the bathroom. My grandparents were similarly conservative, but had "girls sitting on chamber pots", and a PG-13 (suggested) b&w nude, respectively. My classmates and extended family friends also had high rates of this. You'd go to use the restroom and almost always see something wildly out-of-line with the decor of the other public areas of the house.
Who writes about this? What longitudinal studies exist about the shifting tastes involved in how people decorate their homes? Also: Is this (bathroom titillation exception) real and consistent across cultures? Or is it a midwestern, white protestant thing? Or is it not even a thing to that
group, and instead just a confirmation bias I've constructed because of a small sample size of kooky acquaintances? Many thanks for your time and for your impressions.
