All this spring, my son Connor and I have been watching of the original Star Trek on Netflix. Connor likes the original shows almost as much as The Next Generation, and even I find myself getting caught up in some of the more classic episodes like Space Seed (the one with Khan). I also really like the pilot, The Cage. That’s the episode where Jeffrey Hunter is Captain Pike, trapped on a planet run by bubble-headed alien telepaths who throw him in a zoo with the luscious Susan Oliver. (Poor bastard.)

As we watched this particular episode—Connor for the first time, me for the bazillionth—it occurred to me that the Big-Brained Alien is one science fiction trope that has pretty much disappeared. As far as I can tell, it has gone the way of the jet-pack and the glass-tube elevator. This dearth of chrome-domed alien baddies is just another indication, I suppose, of how much things have changed. Back when I was a kid, every extra-terrestrial was guaranteed to have a skull like a beach ball. Even the wise, Christ-like alien Klatuu from Robert Wise’s The Day the Earth Stood Still had a big head (although this was probably no one’s fault—Michael Rennie just had a big damned head!).
Remember those aliens who want to invite all of humanity over for dinner in the classic Twilight episode, To Serve Man? Huge heads. Or the killer vegetable alien in The Thing. Huge freaking head.
As to how this visual cliché came about in the first place, I can only assume it was because of Anthropology class. Specifically, all those anthropology classes that educated, middle-class kids started taking in college during the Cold War. For the first time, ordinary people began to learn about human evolution, and how the human brain has tripled in size during the last two million years. The implication was obvious. Bigger brains means bigger intellect. To extrapolate this trend into the future led to the obvious conclusion: beings of the future will have enormous brains.
In other words, the original Big Brained Alien is…us.
