It’s a well known maxim that nobody wants to be a redshirt on Star Trek: The Original Series. The proud members of Operations, Engineering, and Security are the space-expendables, the first line of defense, the… well the ones who always get sent down with the away party full of more important characters and get murdered by the space monster of the week. Like, all the time. But what if, instead of considering this from the viewer’s perspective, you considered it from the perspective of a crewman choosing a line of work? What if you’re just a redshirt, and not “this episode’s redshirt?”
Matthew Barsalou took this perspective and applied math to it, and lets just say that Kirk, Chekov, and Sulu might not be to happy about it.
