Quick obnoxious quibble with this:
Before I put forth new thoughts, let me clarify that while I do think it is deceptive to clean an always messy living room before a first date — that it is “apt to give a false impression of reality” — I don’t think there is anything wrong with doing so, especially because by general consensus there is no expectation of transparency in that situation.
This just seems like it’s got to be a definitional error. At minimum, to call some behavior deceptive would seem to require either that (1) the person performing it intends that others be deceived, or (2) that the behavior either does or under ordinary circumstances would cause someone to form false beliefs. If, in fact, there’s a general consensus that people will typically tidy up before bringing a first date back—or before having guests over generally—then it seems wrong to expect anyone to form a false belief about the usual state of the apartment, and therefore wrong to ascribe to anyone who tidies up the intention of causing such false beliefs to form.
