I was just recently rewatching "Encounter at Farpoint", and noticed (for the first time) that for Dr. Crusher's first scenes down on Farpoint Station, she was wearing Lieutenant Commander's pips -- which became full Commander once she arrived on the Enterprise. Assuming this was not just an error by the costuming department, it would appear that Crusher's promotion took official effect at the time of her arrival on the Enterprise. That got me thinking about the other characters and their promotions: Worf and LaForge were both promoted twice during the run of the series (including the movies -- then Worf got another promotion during his time on DS9.) Picard and Riker were both offered promotions to Admiral and Captain respectively, a couple of times during the series (that they both refused -- Riker finally accepted his promotion at "Nemesis".) Even Wesley became an acting Ensign during his time on the ship. That leaves Data as the only main character never even to be *offered* a promotion, at any time from Farpoint to Nemesis (disregarding Yar and Pulaski, of course -- neither of whom was on board long enough to get promoted.) I'm wondering why that would have been, when he repeatedly demonstrated his competence in multiple ways? I'm aware of the obvious "anti-android prejudice" argument, but I'm not sure I agree with it. "Measure of a Man" was a great episode, but I disagree with the entire premise behind it. Data had graduated the academy, received the rank of Lieutenant commander, and got assigned as the second officer of the Federation flagship already, *before* the show even started. It's a tough sell for me to believe that all of a sudden he started facing a glass ceiling. A couple of thoughts on my end: 1. He doesn't have the ambition (or at least he didn't, before the emotion chip was installed.) 2. He's so exceptional at what he does as a Lieutenant Commander, that he's literally irreplaceable (therefore he can't be promoted out of a job that he's doing too well to quit.) 3. He's theoretically immortal, so he doesn't *need* to be promoted, at least not as quickly as his human shipmates. Compare to Vulcans like Spock and Tuvok -- their species is long-lived enough that they can have multiple careers. Tuvok even left Starfleet and came back, serving as "just" a Lieutenant at the age of more than a century -- more than double the age of his human commanding officer. (At the other extreme, I could see a short-lived but fast-learning species like the Ocampa being rushed through the Academy in the matter of months, with the ability to make Admiral after only a few years, due to the nature and necessity of their species.) Other thoughts?
