This show is not investment advice and is intended for informational and entertainment purposes only.

[00:00:40] William Green: Hi folks. I’m absolutely thrilled to welcome today’s guest, Emily Haisley. Emily has really one of the most fascinating jobs in the world of investing. She leads the behavioral finance team at BlackRock, which is the world’s largest asset manager with more than 14 trillion dollars in assets under management.
[00:00:57] William Green: She’s a PhD psychologist with a very strong background in academia. But what I think makes her so unusual is that she has this extraordinary depth of experience working in the trenches with fund managers and investment teams within BlackRock, basically helping them overcome their behavioral biases and deal with their emotions and make better investment decisions. I’m particularly excited to have Emily here today, not least because her expertise is really usually on display behind closed doors. She’s a kind of secret weapon within the world’s largest asset manager.
[00:01:32] William Green: So this is a very unique opportunity to learn directly from her about the psychology of investing and all sorts of practical ways that we can use psychology to become more successful investors. So Emily, welcome. It’s really lovely to see you.
[00:01:45] Emily Haisley: Thank you so much for having me, William. I’m most excited just to have a conversation with you because I always enjoy our talk so much.
[00:01:53] William Green: Oh, thanks. It’s a real delight. I’ve been looking forward to this, I think, for two years now since we first met. And, so I’m glad we’re finally actually getting to do this in public. So thank you for coming. You have such a unique and interesting job that I really wanted to start by simply asking you to describe what it is you do at BlackRock. As head of the behavioral finance team, can you give us a sense of your role and your responsibilities there?
