For twenty-some years, Naomi Klein has been a leading thinker on the left. She\u2019s especially known for the idea of disaster capitalism: an analysis that the forces of big business will exploit any severe disruption to take over more space in our lives. She was often confused with another prominent political writer, Naomi Wolf\u2014once a feminist on the left who has, in recent years, embraced conspiracy theories on the right and is now on good terms with Steve Bannon. Klein\u2019s new book, \u201cDoppelganger,\u201d starts with this simple case of mistaken identity and broadens into an analysis of our political moment, which she describes as \u201cuncanny\u201d in the psychological sense. \u201cFreud described the uncanny as that species of frightening that changes what was once familiar to something unfamiliar,\u201d she tells the staff writer Jia Tolentino. \u201cIt\u2019s that weirdness of \u2018I think I know what this is, but it\u2019s not what I think.\u2019 \u201d Klein argues that the left and the right have become doppelgangers of one another\u2014and that denialism regarding climate change has widened to any number of topics, including the claim that Joe Biden is dead and is being played by an actor. \u201cWhenever you don\u2019t like reality, you can just say that it\u2019s not real,\u201d she says.
