Why did the World Science Festival organize a talk about the roots of extremism as part of this year’s celebration? Moderator Maria Konnikova explained that, under the current US administration, it is very hard to escape political discussion. With extreme views on both sides, the question of whether we are becoming a more extreme society is something on everyone’s mind.
Where does extremism come from and are we becoming more extreme? Three psychologists and neuroscientists tried to answer these questions and others at “The Roots of Extremism: The Fundamentalist in Your Brain,” a program on the final day of the World Science Festival in New York City. Jonathan Haidt, social psychologist at New York University’s Stern School of Business, Jay Van Bavel, associate professor of psychology & neural science at New York University, and Katherine Porterfield, clinical psychologist at the Bellevue/NYU program for Survivors of Torture, discussed extremism and fundamentalism, and how it relates to the brain.
