Since 2008, Big Think has been sharing big ideas from creative and curious minds. Since 2015, the Think Again podcast has been taking us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives. Sheelah Kolhatkar is a staff writer at the New Yorker  and a former “risk arbitrage analyst” for two hedge funds in New York City. For the New Yorker, Sheelah writes about Wall Street, Silicon Valley, economics and national politics, among other things. Her latest book is the New York Times bestseller Black Edge, about the largest insider trading investigation in history and the transformation of Wall Street and the U.S. economy. This week’s episode is a departure for us – a deep dive into the personalities, culture, and ideas driving the big banks and the hedge funds of Wall Street. Jason and Sheelah talk about what it was like for her as a woman in that male-dominated industry, how hedge funds have reshaped the whole Wall Street landscape and with it, the global economy, and why billionaire investors are almost required to collect Picassos.
