If they say so.......
Good to be a 'redshirt'
Grime first focused on an age-old assertion: that crewmembers wearing red shirts in the original "Star Trek" series, which denote working in engineering or security, are far more likely to be killed off than any other shirt color.
That claim, in fact, is false — more "redshirts" died on-screen than any other crew type (10 gold-shirted, which are command personnel; eight blue-shirted, who are scientists; and 25 red-shirted, Grime said), but that calculation fails to take into account that there are far more redshirts on the ship to start with than any other crew type.
In other words, we're looking at the probability that you are a redshirt if you die (58 percent) — what we want to know is the probability that you die if you're a redshirt, Grime said.
Grime used the "Star Trek" technical manual to find out how many of each crew type there were, which painted a different picture: out of 239 redshirts, 25 died, which is 10 percent. Out of 55 goldshirts, 10 died, which is 18 percent! So you are more likely to die as a goldshirt, Grime said.
"There is some truth in the old 'Star Trek' myth if you look at security officers … 20 percent of security officers died," Grime added. "So I think the moral of the story is, if you're on the starship Enterprise and you want to survive, be a scientist." (Only 6 percent of the blue-shirted scientists died over the course of the show.)
