This MetaFilter post from 2007 includes the following:
In some families, you grow up with the expectation that it's OK to ask for anything at all, but you gotta realize you might get no for an answer. This is Ask Culture.
In Guess Culture, you avoid putting a request into words unless you're pretty sure the answer will be yes. Guess Culture depends on a tight net of shared expectations. A key skill is putting out delicate feelers. If you do this with enough subtlety, you won't even have to make the request directly; you'll get an offer. Even then, the offer may be genuine or pro forma; it takes yet more skill and delicacy to discern whether you should accept.
All kinds of problems spring up around the edges. If you're a Guess Culture person -- and you obviously are -- then unwelcome requests from Ask Culture people seem presumptuous and out of line, and you're likely to feel angry, uncomfortable, and manipulated.
If you're an Ask Culture person, Guess Culture behavior can seem incomprehensible, inconsistent, and rife with passive aggression.
This was a moderately successful meme (under the Dawkins definition), receiving press attention in The Atlantic, The Guardian, and (with a surprisingly uncritical tone) LessWrong, but the original does not appear to cite any sources. Much of the discussion seems to implicitly assume that the Ask/Guess dichotomy is universally applicable, and that all human cultures can be classified in terms of it. The original post does not quite make this claim, but it comes very close, and everyone seems to be taking it as given.
Is there evidence that this Ask/Guess distinction corresponds to some specific, objectively measurable, and documented personality or culture trait?
