It's an interesting question. I suspect that the nature of media in general is to lend authoritative voice to individuals rather than promote perspectives or ideals, and thus the "voices of science" promoted in the media will themselves become pop-authorities. Plus the fact that the promotion of science in the media seems more for entertainment and ingroup-signalling (ie, politics) than genuine truth-seeking.
