How so? A Vulcan would not have an ego to bruise. The logic of compensating for natural superiority or inferiority might well appeal to those pondering whether to join the organization. If they want to be made instant Admiral as befits their abilities, they can always make the effort of going through all the motions (exams, extra training, hunting for commendations from exceptional performance) - but out of the half a dozen Vulcans we have followed in any sort of detail, none had ambitions of that sort, and even found the idea of high command positions somewhat repulsive.But if that were the case, wouldn't a Vulcan recognize it as being illogical to join Starfleet in the first place?
