Haha, this is nuts. I had no idea mental illness played such a part in the development of science fiction:
In 1950 Horace (H.L.) Gold launched the last of the Golden Age pulps, Galaxy Science Fiction, with the deliberate intention of de-emphasizing technology and concentrating on serious sociological and psychological stories. Unfortunately Gold also suffered from severe agoraphobia, and many writers quickly realized that they could sell to Galaxy by writing fiction that catered to Gold’s illness, hence the large number of “domed city,” “underground city,” and “the whole world is just one big city” stories that dominated printed science fiction well into the 1970s.
