[citation needed] Another early classic writer, Jonathan Swift, penned critical views on current society—his most famous work, Gulliver's Travels (1726), is an example of a novel that is partially social science fiction (with such classic sci-fi elements as pioneering in strange new worlds and experimenting with variations of the human anatomy) and partially high fantasy (e.g., fantastical species that satirize various sectors of society).
Next to prognoses of the future of society if current social problems persisted, as well as depictions of alien societies that are exaggerated versions of ours (exemplified by The War of the Worlds of 1897), Wells also heavily criticized the then-popular concept of vivisection, experimental "psychiatry" and research that was done for the purpose of restructuring the human mind and memory (clearly emphasized in The Island of Doctor Moreau, 1896).
Examples of young adult dystopian fiction include The Hunger Games (2008) by Suzanne Collins, The House of the Scorpion (2002) by Nancy Farmer, Divergent (2011) by Veronica Roth, The Maze Runner (2009) by James Dashner, and Delirium (2011) by Lauren Oliver.
The modern era of social science fiction began with the 1960s,[citation needed] when authors such as Harlan Ellison, Brian Aldiss, William Gibson and Frank Herbert wrote novels and stories that reflected real-world political developments and ecological issues, but also experimented in creating hypothetical societies of the future or of parallel populated planets.
Kurt Vonnegut wrote Slaughterhouse-Five (1969), which used the science-fiction storytelling device of time-travel to explore anti-war, moral, and sociological themes.
Modern exponents of social science fiction in the Campbellian/Heinlein tradition include L. Neil Smith who wrote both The Probability Broach (1981) and Pallas, which dealt with alternative "sideways in time" futures and what a libertarian society would look like.
