Organizations are made of people. People in highly technical or scientific lines of work are likely to pay less attention to social signaling bullshit and more to actual validity of arguments or quality of insights. By writing the sequences Eliezer was talking to those people and by extension to the organizations that employ them.

I am skeptical of this claim and would like evidence. My experience is that scientists are just as tribal, status-conscious and signalling-driven as anybody else. (I am a graduate student in the science at a major research university.)
