"To Quantify the Unquantifiable"

"But Lindsay Rogers might have had a more fundamental critique than that: The idea of political polling was broken to start with. It was a falsely scientific way to put numbers on a concept that can't be measured in the first place, and which changes shape every time you try. And indeed, it is the very elusiveness of political opinion—its resistance to being pinned down—that makes democracy necessary. When we measure mass or distance, we know we can do so accurately. But our values, attitudes and opinions are not concrete but fluid. They change with time—in the days and weeks before an election, as well as in the years in between them. Which is precisely why democracy requires that every few years, we vote anew."
