TRANSCRIPT:

Welcome to the Mel Robbins Podcast with Dr. Leslie K. John

MEL ROBBINS: Dr. Leslie John, welcome to the Mel Robbins Podcast.

DR. LESLIE K. JOHN: Oh, thanks so much for having me.

MEL ROBBINS: I am so excited to dig into everything that you’re about to teach us, your research. And where I want to start is how selfishly, how could my life be different if I take to heart everything that you are teaching at Harvard Business School, the lessons, the takeaway, the research, and I really apply it to my life? How is my life going to change?

Revealing Wisely: A Skill That Transforms Your Life

DR. LESLIE K. JOHN: So number one is the realization that revealing wisely is a skill. It’s not something we’re born good or bad at. It is a skill. And you can do some really practical things, which we’re going to talk about, to do it really wisely. And if you do it wisely, it’s going to transform your relationships. It’s going to change how you show up at work. It’s going to help you thrive at work. It’s going to make you more influential. And it’s even going to shape and improve your well-being, your day-to-day happiness.

MEL ROBBINS: Just by being more open?

DR. LESLIE K. JOHN: Yes. You’re going to notice that your EQ, your emotional intelligence, is going to increase. You’re going to have much better self-awareness and understanding, and you have a much better understanding of others. As a result, you’ll be much better able to identify and process your emotions. You will feel therefore less stressed. You will ruminate less.

You know that post-conversational replay, that gut-wrenching, “Oh my God, what did I do?” That’s going to dial way down because part of opening up is saying hard things. You’re going to learn to be more assertive, which will help you with boundaries beyond. And you’ll feel more — it’s not just the absence of negative stuff or the mitigating of it — you’re going to feel more joy. You’re going to be happier. I sure am. And if this curmudgeonly academic feels that way, you’ll also find benefits in your workplace, in your career.

So it’s interesting because the tools there are kind of counterintuitive, the things that you do to, say, gain more influence. So I’m excited to talk about that.

Selling the Power of Openness to Type-A Overachievers

MEL ROBBINS: Dr. John, I’m sitting here thinking, if you’re standing before a class at Harvard Business School, you’ve got a bunch of really type-A people in there who want to go into investment banking or be the next billionaire or build something meaningful, hardworking, hard driving. They end up in front of you and you’re like, hey, let’s talk about the power of oversharing. How do you sell the benefit of being more open and what you call oversharing to somebody who is just in your class to get ahead? What is the real benefit of that?

DR. LESLIE K. JOHN: Yes, great questions. The way I start is by speaking their language. So I teach a lot of executives, and some of them, rightly so — well, I’m a skeptical person — they’re like, “What is this?” And especially sometimes when it comes to feelings and emotions, “What is this?” And so what I do is I start by showing them in business contexts how this — first of all, this is crass, maybe. I am a business school professor — how it helps them make money. And then I show—

MEL ROBBINS: Wait, so if you share more, you make more money?

How Transparency Drives Trust and Revenue

DR. LESLIE K. JOHN: So the example I give there — I know, what? As a company, so when we reveal, when we share more, when we open up, when we reveal slightly sensitive things, it causes whoever we’re revealing to, to trust us more. And the same is true in companies. When companies reveal more, it causes their trust — and I don’t use the word “cause” lightly, right? These are randomized experiments — it causes their customers to trust them more and to buy more.

So we’ve done studies with the largest bank in Australia, for example, where with my colleague Ryan Buell, we somehow convinced them to, on their credit card website — so when you’re going and looking for a credit card on their bank, Commonwealth Bank of Australia — what we convinced them to do is half of the time to reveal reasons why you might not want the credit card. So like, “Pay attention, the fees are really high,” or “The points aren’t great,” or “The high interest rate” — basically drawing attention, saying don’t buy this. But that’s a form of sensitive disclosure, right?

And what did that do? It actually did not scare people away. It didn’t decrease customer acquisition and it increased retention. The experiment alone made the bank millions of dollars, and then they rolled it out and then their competitors copied them. So that’s kind of where I start, in the money realm. And then they’re like, “Oh, okay.”

And then I go into leadership, and there I go into how when you’re a leader, revealing a little bit more than you think you should — I take them through, I first get them to craft a little self-introduction.
