Everyone who writes has got an agenda, but Science fiction writers may be the most opinionated of authors. That's because their pigeon involves prediction, which in turn, is a personal interpretation of current trends. They can't help but express their own biases in their work. And so we have Robert Heinlein and his penchant for plugging love of cats, libertarianism, and nudism (not necessarily in that order!). Dr. Asimov denounces anti-scientific themes in his works. It is no secret that I advocate for the equal representation of women and minorities.
John W. Campbell, editor of the monthly science fiction digest, Analog, is a big fan of psi – the ability of the human mind to alter matter.
Psi is one of those "pseudo-sciences." To date, I don't think there has been a scrap of compelling research as to the existence of ESP or telepathy or precognition, save in the parlors of the less reputable carnivals. Yet it can make for interesting storytelling, a sort of modern magic. I don't mind it so much in my stories, any more than I mind Faster than Light space travel, which is just as baseless.
That said, Campbell, who has more power projection than a single writer, is a psi fanatic. It's rare that an issue of Analog appears without at least one psi-related story, and most have several.
Like this month's, the September 1961 issue:
