Mel Robbins Podcast: w/ Dr. Katy Milkman on the Science of Change (Transcript)

Here is the full transcript of behavioral scientist Dr. Katy Milkman’s interview on The Mel Robbins Podcast, December 29, 2025.

Brief Notes: In this empowering episode of the Mel Robbins Podcast, Mel sits down with Wharton professor and behavioral scientist Dr. Katy Milkman to reveal why change feels so hard and why it has nothing to do with you being lazy, broken, or lacking willpower. Drawing on research from over 190 scientists, Milkman breaks down the seven hidden barriers that quietly derail your goals—like impulsivity, procrastination, forgetfulness, and conformity—and matches each one with a specific, evidence-based strategy that actually works in real life.

The conversation also unpacks the “Fresh Start Effect,” showing you how to use birthdays, Mondays, new years, and other chapter breaks as psychological launchpads for new habits instead of waiting for motivation to magically appear. Whether your goal is to save money, get healthier, quit a bad habit, or finally follow through on long-delayed plans, this episode gives you a practical, science-backed playbook to make change stick in 2026 and beyond.

Welcome and Introduction

MEL ROBBINS: Professor Katy Milkman, welcome to the Mel Robbins Podcast.

DR. KATY MILKMAN: Thanks for having me.

MEL ROBBINS: I really appreciate you making the time. I’ve been a fan of your work for over a decade and I love that we’re going to get this chance to dig into research that helps you change your life. It’s informed some of the biggest books on habits on the planet, and now we have the OG with us in person.

I want to start, Professor Milkman, by talking about how could my life be different if I take everything you’re about to teach us, the research you’re about to explain, and I apply it to my life? What’s going to change?

The Power of Evidence-Based Change

DR. KATY MILKMAN: Every single person has a goal. You have a goal that you want to achieve right now, even if you haven’t articulated it. There’s some aspect of your life that you want to improve, you want to get better at. And there’s also probably people you care about who you want to help improve.

And there’s a lot of science that you can use to get there faster and with higher probability. But most of us, when we have that goal, when we have someone we care about we want to help achieve a goal, we’re just shooting from our hip. We are not basing our strategies on evidence.

And what I hope to share today is a set of tools you can use immediately to make it easier to achieve whatever it is you want to achieve and to help other people do the same. Whether that’s getting in shape, whether that’s getting your finances in order, whether it’s getting a promotion at work, whatever that goal is you’re trying to tackle, we actually have evidence-based tools to help.

So hopefully by the end of this episode, you’ll have learned and grown a lot in ways that will allow you to be a stronger version of yourself as you approach a new goal.

MEL ROBBINS: You know what I’m excited about? I feel very optimistic all of a sudden because you’re here. No, I mean that. I mean that sincerely, because I think a lot of us have that experience of really wanting to change.

And I appreciate you validating that inside each and every one of us is a desire to feel better and do better. And we not only want it for ourselves, we want it for the people that we care about.

And so before I ask you my next question, I just want to speak to you as you’re listening or as you’re watching us on YouTube. Because everything that you’re about to learn, the research that Professor Milkman’s going to unpack, the evidence-based strategies, they’re universal to all of us.

But I want to make this personal as you listen or watch. And so I do want you to think, what is the goal? What is the change? Is it saving money? Is it eating healthier? Is it exercising more? Is it losing weight? Is it spending more time with family and friends? Is it quitting smoking or vaping or drinking? Spending less money? Getting a better job?

Think about what you want to change for the better. Because if you have that in mind, you can apply all this evidence and all this research to every single goal you might have in life. So I just invite you to do that because it’s going to make this way more impactful for you.

You know, Professor Milkman, you have spent your entire career not only studying, researching, writing and teaching about why change is so hard. What is the biggest lie that we’ve been told about change?

The Willpower Myth

DR. KATY MILKMAN: I think the biggest lie is that you should just work harder or use your willpower and that there’s something wrong with you if you can’t push through the pain and achieve this challenging goal.

And the truth is that’s not the key to change. It’s not that you lack something inside you and that’s the reason that you can’t do it. It’s actually normally that you haven’t set up the right strategies, you don’t have the right support systems. There’s not something broken in you.

And if you blame the way you’re designed and you say, “I don’t have the willpower to make this change,” or “there’s something wrong with me and I can’t do it,” you’re setting yourself up to fail.

It doesn’t just take willpower or grit or fortitude. It takes strategy and it takes understanding. How do you set yourself up for success despite the fact that doing hard things is hard? You have to change it so that doing hard things becomes easy, because no one’s good at doing hard things.

So we have to make it enjoyable, we have to make it memorable, we have to make it social, we have to bring to bear all the best evidence to strategically overcome these challenges, and we can use the tools that are going to lead us to success instead of to failure.

MEL ROBBINS: Well, what I love about where you’re starting is I think most of us, when we have a big goal and we really want to change, but we can’t seem to figure out how to make the change stick or how to change at all, what I’m starting to get, which I think is a brand new idea for me, is that based on the evidence and based on the research that you’re about to share with us and based on the strategies you’re going to teach us, learning how to change is a skill.

Change as a Learnable Skill
