> People in humanities still haven’t understood that pretty mich everything in their fields is never all black or all white

I think most would be very open to be checked on their priors, but I would be very surprised if those could be designated a single color. In fact, the humanities revel in various hues and grays rather than stark contrasts.

> But which contributes more, they ask? Who gives a shit, really?

Funding agencies? Should they prioritize established researchers or newcomers? Should they support many smaller grant proposals or fewer large ones?

> it’s glaringly obvious that small contributions matter

Not at all obvious to me. What were the small contributions to e.g. the theory of gravity?

Humanities? Why'd you drag humanities into this?

(I agree with your point, by the way.)
