I like this essay very much. It realises that science without scientists is impossible, thus bringing back the subjective part into science is mandatory. Although that part never really was detached from science (since science without scientists is impossible), I appreciate the essay's approach for trying to bring it back to the conscious level.
Undeniably, almost everything humans do is to a huge extend value-driven. So there are value-systems which in turn shape belief-systems, not only in science, but all over the human population. Since the set of all these belief-systems is such that this set obviously contains many internal contradictions, the latter imply that there must be a whole lot of biases implicit in that set, since not all opposing beliefs can be true at the same time.
Although I would not exclude the possibility that scientists will adopt the needed corrections outlined in this essay, I am more sceptic about the rest of humanity. But one has to start somewhere, and if scientists make the first steps, maybe other people will follow.
