Leo Hollis (LH): Thinking about your own story, the one that you talk about in Weapons of Math Destruction – you started off in academia studying maths, then went into the City, a fairly common move.

Cathy O’Neil (C.O.): I actually walked into the crash. I left my professorship in June 2007, started a hedge fund, and in the summer, very soon after I came in – that was when the financial crisis started, from the perspective of people inside finance.
