Soft science fiction, often abbreviated as "soft sci-fi," is a subgenre of science fiction that emphasizes the social sciences, such as psychology, sociology, and anthropology, over the hard sciences like physics and chemistry. Unlike its counterpart, hard science fiction, which focuses on scientific accuracy and technical detail, soft science fiction explores the human condition, societal changes, and speculative futures through the lens of technology and its impact on society. This genre often delves into themes of ethics, culture, and human relationships, using futuristic settings and speculative technology as a backdrop to examine how these elements interact and affect individuals and societies. Soft science fiction is less concerned with the how and why of technology itself, and more interested in the implications and consequences of technological and societal evolution, making it a rich field for exploring complex characters, speculative societies, and philosophical questions.
