Aggregating individual opinion (sometimes) has a washing-out effect on bias, which makes it valuable as a tool to push towards objectivity. [0]
This is why I much prefer to follow guidance from institutions over individuals. There's also a "stewardship" in institutions that seems effective in countering other forms of bias (but not all).
Of course there's a whole lot of bias left over that doesn't make this a fire-and-forget strategy, but comparatively it seems closer to objectivity than to just trust one's eyes alone, which has effectively zero systemic corrections for bias.

Reputability is the aggregate of individual opinion, which is the definition of subjectivity.
