Soft SF focuses more on the character interactions, cultural implications, and the way that society as a whole is impacted by science and technology, or the lack thereof.
While it does have science fiction at the heart of the setting and plot, it is secondary to the characters and their story. Science is a backdrop against which the play of life is presented. Any science has to be correct, but it can be glossed over to focus on the personal interplay.
Magazines like Asimov's Science Fiction prefer softer science fiction, while the harder stuff gravitates towards Analog. Examples of soft SF include space operas like Rogue One and Dune.
