You'll sort of notice that pulp science fiction stories have some common themes.
This could be both the influence of the magazine editors, as well as a reflection of the era that they were written in.
Rugged individualism tends predominate most early forms of science fiction, possibly to both due to a prevailing ideological view at that time, and what the writer might be projecting what their audience wants.
Politics gets more prominent b the Fifties, as science fiction is used as a basis to discuss (then) current social issues, and I think, more cynical mid Sixties onwards.
I would say Dune would be one marker, where the cult of the hero gets subverted.
The superhero aspect tends to get transferred to comics.
