While I love Humans as Space Orcs, can we get some exploration of this theory, that humanity's 'hat' in the galaxy full of Planet of Hats that is Star Trek is that we're Doc Brown? Please note the reason Scotty's Chief Engineer of the Enterprise, as well as the Vulcan Science Academy's interactions. (Also this might explain why the multispecies Federation ships in TOS-era seem to be crewed in an almost entirely monospecies manner, what with that all-Vulcan ship in one episode, and Spock and very few others on the mostly-human Enterprise). -- RecklessPrudence
Word association in the Federation tells a lot about expectations. 'Klingon' leads to 'warrior'. 'Cardassian' to 'soldier'. 'Vulcan' to 'scientist'.
