Ask HN: Can complex emotions be represented as combination of simple emotions?

One of the revolution in CS was of boolean algebra. Laws of thought were never so explicitly formulated then. Now say for example at HN we upvote a link or downvote a link, our complex emotions are reduced to simple Yes or No kind of choice. For example one may vote a response Up only because he agrees with it. Or he might vote it up because he think it adds value to the discussion (but not necessarily agree with it)
