Is this your cheeky and coy way of saying that objectivity is not possible? What's really the difference between impartiality and objectivity in this context? Sounds like you're just being a wordsmith.
What we call "objective" is usually just invisible judgment that aligns with our priors. An observer's choices about what to include, exclude, measure, or frame shape reality long before conclusions appear.
Scientific facts are just theories that haven't been proven wrong yet.
