What Is Recency Bias and Why Should You Care?

January 28, 2025
Today I want to talk about a bias that can be a real pain in the neck — whether you’re choosing the right goal to tackle or the best restaurant to recommend to a friend. It turns out we have a suboptimal tendency to fixate on what’s top of mind, and one way things get to the top of mind is by being recently encountered.

Friends Don’t Let Friends Shirk on Shared Goals (Like Voting!)

October 29, 2024
With just a week until Election Day and as a resident of a key swing state, I’ve been thinking a lot about how I can help get out the vote. Happily, my fellow behavioral scientists have done some terrific research showing small but effective steps we can all take to encourage our friends and family to head to the polls.

The Remarkable Effects of Asking: “How Does That Work, Exactly?”

September 24, 2024
What most of us learn when we’re asked “how does that work” is that it’s surprisingly hard to say. And that’s the focus of this week’s interview, but with a twist — it turns out that asking for explanations of how things work can lower the temperature in political debates (a tip that feels timely as we approach a contentious American election).

Do You See Your Life as a Portfolio of Choices?

June 25, 2024
Life is full of repeated decisions. Day after day, we choose what to eat, who to socialize with, where to travel, who to hire, whether and how to exercise and so on. What’s fascinating is how often we consider these choices in isolation — deciding what to eat for lunch as if we won’t make the same decision again tomorrow.

Can Your Mood Move the Market?

May 28, 2024
It’s the end of another academic year, and as a professor, I usually feel only happiness and excitement in the air as graduates prepare to walk the stage and accept their diplomas with lots of pomp and circumstance. But this year the mood is different. College campuses around the country (mine included) have seen an unusual degree of discord. The noticeable sentiment shift got me thinking about the interview I feature this month, which dives into some of the research on how much the collective mood of a region, country or even the globe can matter in ways that I, at least, find fascinating and a bit counterintuitive — affecting our decisions, our health, and even the stock market. I hope you’ll find it interesting.

Are You Harnessing the Magic of DIY?

April 30, 2024
Since the last edition of this newsletter, the field of behavioral science has suffered a truly monumental loss. On March 27th, emeritus Princeton psychology professor and Nobel Laureate Daniel Kahneman passed away. Danny’s work with Amos Tversky in the 1970s laid the foundations for everything I study and discuss in this newsletter, demonstrating that decision makers are poor intuitive statisticians, which leads us to make many systematic mistakes (like worrying too much about low-risk events that we can imagine vividly, e.g. shark attacks).

What Does It Take to Be Remarkable

March 26, 2024
An unexpected upside of writing How to Change was that my “book tour” introduced me to some really neat people who don’t run in my usual (wonderful but wonky) academic circles. I met a curious group of podcasters, journalists, and organizational leaders with a taste for behavioral science, and one new connection who particularly stood out was a charming surfer, author, podcast host and product evangelist named Guy Kawasaki.

Do You Think Proportionally

February 27, 2024
Every winter, I have the pleasure of (re)teaching a Wharton MBA course that covers classic psychology research on decision biases and heuristics. I’ve been teaching this material for fifteen years but it still feels fresh and fun because the takeaways are so clear and practical.

Can a Small but Growing Trend Change Your Mind?

November 28, 2023
This fall, after noticing a pronounced drop in the fraction of Philadelphians sporting skinny jeans and an uptick in bootcuts, I’ve begun slowly retiring my (still comfortable and sturdy) skinny jean collection for more “modern” replacements. Please don’t judge my wastefulness too harshly. I’m far from a fashionista, but like most people, I respond to peer pressure, and when trends shift, I don’t want to be the last goofball caught wearing dated styles.

Can Behavioral Science Help the Government?

October 31, 2023
It has been a tumultuous month (to put it mildly). While the Q&A I’ve chosen to feature this month is unrelated to the upheaval all around us, it’s with Dr. Maya Shankar, who hosts my favorite podcast on coping with unforeseen change. As you’re confronting change, I highly recommend checking out A Slight Change of Plans, which Apple named the best podcast of the year in 2021 for good reason.

Can You Hack Your Memory?

September 26, 2023
Today, I’m bringing you a Q&A with Harvard Professor Todd Rogers whose incredible new book WRITING FOR BUSY READERS hit the shelves in early September. Todd is a renaissance man — a renowned academic, successful entrepreneur, and winner of the prestigious Rising Star award from Politics magazine for his efforts to bring behavioral science to Washington. Our Q&A focuses on the power of forgetting and what can be done to remember better. But Todd’s book will help you write better (and more memorable) prose, and that’s a skill we could all use (particularly the author of this newsletter!).

What Are Your Regrets?

June 27, 2023
In academia, summer is the season for reflection. College campuses go quiet, email traffic slows, and there’s finally room to consider what’s made you proud and what you most regretted in the last two semesters. I briefly entertained the notion of sharing a list of wins and woes from the past academic year in this newsletter. But anticipating I’d soon come to regret that (ahem), I instead decided to devote this issue of Milkman Delivers to a Q&A about the science of regret and the impact it can have on our decisions.

Why Does Your Mindset Matter?

May 30, 2023
This year, I’ve had the great pleasure of reading the Harry Potter books to my seven-year-old son (an activity I highly recommend to all parents). In one of my favorite scenes from the series, Harry cleverly uses behavioral science to help his best friend succeed. On the day of a major sporting event, Harry tricks his teammate and fellow wizard, Ron, into believing that a bit of a valuable and rare luck potion is in his breakfast. Ron’s confidence soars as a result, and his performance on the field is unusually strong. However, we learn that no magic was actually deployed—Harry just relied on sleight of hand to mislead his friend and thereby change his mindset.

Are Exceptions as Exceptional as We Think?

April 25, 2023
Every fall when my university’s academic calendar kicks into high gear, I tell myself that this term I’ll manage to stay on top of my work and avoid late nights writing reports, tweaking presentation slides and answering emails. I’m always sure that last semester’s challenges were an exception and this year will revert to “normal.” There was the year my son was born, and that naturally threw me for a loop, but he was destined to be an only child so I told myself I’d eventually settle back into a rhythm involving some balance. Then I started a new research center, and birthing that was its own wild ride. However, I knew the startup pain was only temporary. Of course, just as that madness started easing, I signed a contract to write a book, which was immensely time-consuming. And then there was the COVID-19 pandemic, which meant a spike in work hours spent on childcare. But once elementary schools and after school activities re-opened all would be sane again, right? Then came the surprise of an arduous committee assignment, but that’s wrapping up soon, so next year things will surely improve …

Are You Overconfident?

March 28, 2023
These days, when I walk into a classroom, I have tremendous confidence — probably too much. It’s bred from experience, as I’ve been teaching at Wharton since 2009 and have cumulatively lectured to thousands of students. But sometimes, unfortunately, my confidence has led me to under-prepare for a presentation, and I’ve been caught flat-footed when pressed on a topic outside my area of expertise. As an assistant professor, though, I had the opposite problem. I spent so much time prepping my slides, memorizing student names and anticipating questions that my delivery of material was often stiff. Strangely, I’ve spent the bulk of my teaching career miscalibrated — at first I was under-confident in my abilities, and now I’m over-confident. Why can’t I just get it right?
