I’m not sure that those factors can be fully, or even partly, separated from status signaling. For example, I expect that I could tell the difference between different kinds of pickles, and develop a favorite among the brands that exist. I have no particular reason to do so, and if I did, I wouldn’t talk about it, but if pickles became trendy, and the pickle companies started making subtly-different types to satisfy the demand for signaling tools, I probably would at least try the varieties and pick a favorite. (I have a favorite brand of mayonnaise, after all, and am that picky about which brand of Macadamia nuts I’ll eat.)
