In science there are ways to surface subjectivity (cannot be counted) into observable quantized phenomena. Take opinion polls for instance: "approval" of a political figure can mean many things and is subjective, but experts in the field make "approval" into a number through scientific methods. These methods are just an approximation and have many IFs, they're not perfect (and for presidential campaign analysis in particular they've been failing for reasons I won't clarify here), but they're useful nonetheless.

Another thing that get quantized is video preferences to maximize engagement.
