In what way is Kurt Vonnegut's short story Report on the Barnhouse Effect an example of postmodernism?

"Report on the Barnhouse Effect" by Kurt Vonnegut reflects postmodernist themes through its satirical approach to science and academia, questioning the ethics of scientific development and the manipulation of knowledge for power. The story blurs the line between reality and fiction, playing with metafictional elements and engaging with the absurdity of contemporary society. This self-aware narrative style, along with its critique of authority and technology, places it within the realm of postmodern literature.
