Maybe my meaning was lost. I don't think it does a service to our political dialogue when we casually throw "mostly left-leaning" on "scientists." We don't want to encourage the instant siloing / ignorance that can accompany labeling someone whose profession is gathering objective evidence with a particular subjective political tribe.

Language matters. I think "reality has a liberal bias" and other patronizing quips have helped usher us into a post-truth era.
