From Eliezer Yudkowsky at the very challenging and stimulating Overcoming Bias:

This fallacy gets its name from an ancient sci-fi TV show, which I never saw myself, but was reported to me by a reputable source (some guy at an SF convention).  Anyone knows the exact reference, do leave a comment.

So the good guys are battling the evil aliens.  Occasionally, the good guys have to fly through an asteroid belt.  As we all know, asteroid belts are as crowded as a New York parking lot, so their ship has to carefully dodge the asteroids.  The evil aliens, though, can fly right through the asteroid belt because they have amazing technology that dematerializes their ships, and lets them pass through the asteroids.

Eventually, the good guys capture an evil alien ship, and go exploring inside it.  The captain of the good guys finds the alien bridge, and on the bridge is a lever.  “Ah,” says the captain, “this must be the lever that makes the ship dematerialize!”  So he pries up the control lever and carries it back to his ship, after which his ship can also dematerialize.

And from there, Yudkowsky goes on to discuss the quicksand foundations of psychology and Artificial Intelligence. Well worth the time and skull sweat.

One mild demurrer: If you look over at my Categories, you’ll see that I deride psychology as “Witch Doctoring”. This is in response to claims that psychology is in any way a science; it is not, because it lacks underlying mechanisms and testable hypotheses.

However, it’s easy to ridicule the field in hindsight, without viewing it in its historical context.

Imagine, to use the opening metaphor, that you live on a ship, have been raised on a ship, where nobody has ever been in the bridge; indeed, no one even knows the bridge exists. The ship simply flies around the universe, completely out of control. The origins of the ship, and the technology and science underlying its operation, have been forgotten so long ago, no one even remembers the ideas of technology and science. It is not unreasonable that all sorts of bizarre superstitions should arise as to how to direct the flight of the ship.

Then one day an ignorant, superstitious, but curious savage, fellow by the name of Freud, finds this rusted-shut hatch….

Sounds like a great idea for a science fiction story, eh? The idea of a colonial ship carrying crew and passengers who have forgotten their origins is indeed a popular one, although I don’t recall this particular issue being explored.

A couple of the best examples are Alfred Bester’s novel The Stars My Destination, and Gene Wolf’s tetralogy Book of the Long Sun (Actually, a long cycle of novels). There’s another novel (which I read in high school, so pre-1972) about a militaristic religion, with enforcers based on the Spanish Inquisition, deliberately set up to control the population of a colony ship; damned if I can remember its title or author, though. Then there’s The Starlost, a disasterous TV series disowned by its creator, Harlan Ellison.
