The government are very keen on amassing statistics. They collect them, add them, raise them to the nth power, take the cube root and prepare wonderful diagrams. But you must never forget that every one of these figures comes in the first instance from the village watchman, who just puts down what he damn pleases.
The definitive study of the herd instincts of astronomers has yet to be written, Fernie said, but there are times when we resemble nothing so much as a herd of antelope, heads down in tight formation, thundering with firm determination in a particular direction across the plain. At a given signal from the leader we whirl about, and, with equally firm determination, thunder off in quite a different direction, still in tight parallel formation.(quoting an observation made by astronomer J. Donal Fernie)
I believe that science fiction is as profound as you want it to be or it can be very simple entertainment, and I'm all for very simple entertainment. Every now and then we all need to come home, veg-out, watch something and not think too deeply about it. It's what you want it to be. We tend to steer clear of being pedantic; it's entertainment first, otherwise we'd be on a lecture circuit.
