alt Hacker NewsIsn't that likely to be the other way around? You tend to eat most often that which you prefer?
Granted familiarity itself can play a role when considering something unfamiliar. But when it comes to both rice and coffee I purchase what I do because I significantly preferred it to the variants I tried before it.
I don't think so, because there are too many things, but not enough time in life to find out your true preferences for them all, so we all are (to varying degree of) indifferent to most things, and focus on only a few things we truly care about. For you, it's coffee and rice; for others, it may be monitor latency and keyboard switches.
I'd used coffee as an analogy, because it's something that almost everyone drinks, has many varieties, but most generally aren't too picky about it. Alas, I'd underestimated the population overlap between HN readers and picky coffee drinkers. :-P
