Is there such a thing as human-friendly decorating which is gender non-specific?
How about an intersection between male-friendly and female-friendly decorating (assuming that such things exist)? In your example, female-friendly decorating seems to be a subset of male-friendly decorating, so in this case, intersection equals to subset, so “having every surface covered with something expensive” is a solution which satisfies everyone.
Though I am a bit suspicious of the data. First, it seems to be somehow resistant to falsification, because even if I give you an example of something unexpensive which is pleasant to be around, you can replace it by an improved version of the same thing, which will probably also be a bit more expensive. In other words, are expensive things pleasant per se, or does it just mean that when you optimize too much, it tends to get costly? Second, decoration good for casino does not have to be good for other purposes.
