I am not a big fan of re-posting others' stuff, but this gem seems to be hard to get and it is not just funny, but actually true, meaning that if you are for example an undergrad and you want to know how the postdoc feels about you, here is your answer.
Of course, the PI sees only the female undergrads that way (if they are male and straight), but nevertheless, yes they do! And the one with the postdoc perceiving the technician: the technician is the one telling the secret, the postdoc is the one whose eyes are opened.
Sure - this is biased from a technicians perspective, but their perspective is somewhat elevated actually, and they see scientific academia as what it is and as it is depicted here: A kindergarden.
