Soft Science Fiction
Soft, or "social," science fiction is a subgenre of science fiction in which the plot relies on the "soft sciences" (psychology, anthropology, sociology, etc.). First-contact stories fall into this category.
Soft science fiction is hard science fiction's counterpart, and is more focused on speculations about how thinking about self and society would change humanity.
Some readers do not consider soft science fiction to be a separate genre as much as a nuance of science fiction. Book Country's genre map will continue to change as new literary categories emerge and others fall out of fashion. If you write soft science fiction, explore the subgenre to connect with other like-minded writers, workshop, and publish your book.
