I would say that the antagonism between politics and truth-seeking goes back to Plato and Aristotle, and people who specialize in one tend to hold the other in contempt (or at least suspicion).

Science is about being right and politics is about a plurality of people working together. In the name of cooperation, politics prefers vague language that is decidedly un-formal whereas science gravitates toward mathematical precision. Both are necessary, but I'd say we're leaning too far into politics these days.
