David Epstein Interview Transcript

Pete Mockaitis
David, thanks so much for joining us here on the How to be Awesome at Your Job podcast.

David Epstein
Thank you very much for having me.

Pete Mockaitis
Well, I’m excited to dig into the stuff but, first, I want to hear about your work as an ecology researcher in the Arctic.

David Epstein
So, I studied geology and astronomy in college and, afterward, I worked in a plant physiology lab and that led me living in the Artic in the far north of Alaska, a place called Toolik Lake, where I was basically studying the radiation that plants give off in an effort to sort of help try to understand how the carbon cycle might change as that area warms and the permafrost melts a little because most of the ground is frozen there, so when there’s melt, a lot of nutrients are liberated and they can cause like major changes to the plant life which can cause changes to the carbon cycle.

Pete Mockaitis
Intriguing. And so, how long were you there and what was life like up there?

David Epstein
Yeah, I was basically there for, well, you couldn’t be there a lot of the year because you couldn’t get supplies, so you can only really be there for like half the year basically. I loved it actually. So, it’s technically a desert and I love deserts because even though it’s lush on the ground and the air is cool enough year-round that there’s not much atmosphere and demand for water so you don’t get much rain even though there’s a lot of fog and slush on the ground.

And so, all the plant life is really low to the ground, and so in the middle of summer, when it’s basically light all day and you’re sort of seeing this, the sun go down and just come right back up and all the plant life is low, you can see really far and make for some great hiking. I thought it was beautiful. Some people felt it was desolate who were up there but I loved it.

Pete Mockaitis
Well, yeah, I’m curious if that isolation can serve as just amazing, creative, energizing time, or like, “I am going insane.”

David Epstein
Yeah, I’m more on the creative, energizing side, and I think like when I asked, after my first book, people would often ask, “How did you write it?” and I really don’t know how to answer that question because I’m not really sure. Every project is kind of different. And I asked my wife once, I asked her, “How did I write it?” and she said, “You went upstairs and came back down two years later.” And so, I’m pretty good at spending time on my own for projects and being quiet out in the expanse of nature. It’s definitely more creative and invigorating for me than a feeling of isolation.

Pete Mockaitis
Oh, cool. And you’ve recently channeled your creative energies into another opus, a grand tome, I’m excited to talk to you about. So, maybe why don’t we start with some of the most fun tidbits in terms of what would you say is perhaps the most surprising and fascinating discovery you made while you’re putting together your book Range?

David Epstein
For me, it was this idea that there are things that you can do that cause really rapid short-term improvement that can systematically undermine your long-term development. So, to that point about surprising, I’ll mention the single study that was probably it’s certainly one of the most surprising in the book to me was this one that was done at the U.S. Airforce Academy where they had a setup that you would never be able to recreate in a lab because basically they would get in a freshman class of, whatever, a thousand students, or several hundreds of students, and those students all had to take a sequence of three math courses: Calculus 1, Calculus 2, and then a third course.

And they were randomized to Calculus 1 to a professor, and then re-randomized for the second course, and then re-randomized for the third course, and they all take the same tests. So, these researchers recognized that this was an excellent natural setup for studying the impact of teacher quality, or teaching. And so, the finding of this study was that the professors who were the best at promoting contemporaneous achievement, that is whose students overperformed on the Calculus 1 test the most compared to the baseline characteristics they came in with, those students, then, systematically underperformed in all the follow-up courses.

So, the professors whose students did the best in Calculus 1, they rated those professors the highest, then went on to underperform in future classes. And what the researchers concluded was that the way to get the best results on the Calculus 1 test was to teach a more narrow curriculum that involved a lot more what’s called using procedures knowledge where you learn how to execute certain procedures and algorithms and you don’t learn more of what’s called making connections knowledge where the curriculum is broadened and you’re forced to kind of connect types of concepts and learn how to match strategies to types of problems as opposed to just execute procedures.

And so, when they’ve moved on into these other courses, those students who had the more narrow curriculum were systematically undermined. And that’s sort of one of the themes that runs through Range are the things you can do that seem the best in the short term sometimes undermine long-term development, and I thought that was just an amazing display of that and an amazing study.

Pete Mockaitis
Wow. It’s sort of like the items that were being covered on the final test is sort of like, “Yeah, he drilled on real good over and over and over again and thoroughly,” but sort of at the expense of getting some broader conceptual understanding of how the math number, calculus, stuff is working I guess more globally.

David Epstein
Right. And that’s what they, then, would need, that’s what then would help them kind of scaffold later knowledge, so they didn’t do as well in those other classes. First of all, that was just deeply counterintuitive finding to me, but also, so I remember, for example, the professor, out of a hundred, whose students I think did fifth best on the Calculus 1 exam, and he got the sixth best student ratings overall, was dead last in what the research called deep learning, that is how his students then did in the follow-on courses.

And so, that’s really kind of worrisome. The fact that a lot of these strategies, and that chapter four of Range is about these learning strategies, and a lot of those strategies cause the learner to be more frustrated, to not do as well in the short term, and to rate the person teaching them worst. So, that’s kind of worrisome because these professor ratings may not be a good indication of what someone is learning. Their own assessment of their own learning in the short term may not be a good indication either. So, that’s, I think, something that’s important to be aware of.

Pete Mockaitis
And so, I’d be intrigued then to correlate that, if you were to sort of draw some parallels into the professional working world, in terms of how might we be shooting ourselves in the foot if we’re trying to master a certain narrow domain of work.

David Epstein
Yes, so let me give another example that came out of the research that I think relates to this. So, in this one study, people who were playing the role of, basically, simulations of naval officers, essentially, and they were being trained to respond to types of threats based on cues. And one group would practice threats where they would see a certain type of threat again and again and again and again, and they would improve and learn how to respond to it. And then they would see the next type of threat again and again and again, and so on.

The other group would get all these different types of situations all mixed up, and that’s called interleaving, and that kind of training is often more frustrating, it slows down initial progress, the learner will say that they didn’t learn as much, and all those things. And then both groups were brought back later and tested on situations they hadn’t seen before. And in that scenario, the interleave group performs much better than the other group because, again, they’re being trained to sort of match strategies to problems as opposed to just how to execute procedures.

And I think that goes for anything we’re trying to learn. I think our inclination is usually to pick up a new skill and do it over and over and over, when, really, we want to vary the challenge a lot early on so that you’re building these broader conceptual skills. And not only do you want to vary the challenge, but I think when we think about, at least in my life, the sort of formal professional development that I’ve been exposed to as opposed to kind of the informal professional development that I do on my own, is always coming away where it’s like, “Okay, here’s the topic, you’re going to learn this topic, and then you move on from it forever.”

And, in fact, the best way, we should actually use what’s called the spacing effect where you learn a topic and then you come back to it later, and that sort of helps you solidify it. So, one of the famous studies here is two groups of Spanish vocabulary learners who one group was given eight hours of intensive study on one day, and the other group was given four hours on one day, and then four hours again a month later. So, they all had the same total study.
Eight years later, when they were brought back, the group that had the space practice remembered 250% more with no practice in the interim. And so, I think we should apply that to anything we want to learn instead of just doing a topic and moving on from it. You don’t have to do it as intensively but you should wait until actually you’ve kind of forgotten it and then come back to it and do it again. And that’s how you like move it into your long-term memory basically.

Pete Mockaitis
Oh, that’s really cool. And it seems like this is drawing some connections for me with regard to, we had the Korn Ferry CEO Gary Burnison on and we were talking about their top competency that maps to all sorts of career successes, what they’re calling learning agility which is sort of the notion of sort of knowing what to do when you don’t know what to do.

David Epstein
That’s really important.

Pete Mockaitis
And so, that would make great sense because as you sort of rise in the ranks and you encounter more and more ambiguous and puzzle-some and, “I have no idea what’s going on” types of issues, the more that you struggle those things the more you’re raring to say, “All right. Well, let’s see how we go about figuring this out.”

David Epstein
Yeah, and I think that gets at sort of a link between the two things we’re both talking about in this classic research finding that can be summarized as breadth of training predicts breadth of transfer. Transfer means taking your skills and knowledge and attempting to apply it into a totally new situation that you haven’t seen before. And breadth of training breeding breadth of transfer basically means the broader your early training was, the diversity of the situations you’re forced to face, the more likely that when you’re in a totally new situation, you’ll be able to will that knowledge and transfer that knowledge to that new situation.

Pete Mockaitis
I see. Okay. So, now, would you say that’s sort of the main idea or thesis behind Range or how would you articulate it?

David Epstein
No, I think that’s just part of this, the theme of Range that is, I mean, the overall theme is sort of that society may overvalue specialists and undervalue generalists. But the theme beneath that, to me, is again that these things that are the most efficient ways to get the quickest improvement, whether that’s telling someone to specialize right away, or practicing in this repetitive specialized way, is often not the way to get the best long-term improvement.

Pete Mockaitis
Yeah. Boy, there’s just so much, so many implications to that in terms of if you think about sort of what you’re measuring and if you think about training or learning or development things. It’s sort of like you often don’t have the luxury of checking in sort of months or years later to see how we did. And so, there’s all kinds of systematic forces that would point us to doing just the opposite of that.

David Epstein
Yeah, totally. This project, in some ways, started in the sports world for me and only the introduction of Range is in the sports world but one of the things that got me interested there is that there’s this incredible drive to early specialization in youth sports. And then I went and looked at what the research says about optimal development, and it says that athletes who want to become elite, typically, have what’s called the sampling period where they play a variety of sports to gain these broader physical skills, scaffold later learning. They learn about their interests, they learn about their abilities, and they delay specializing until later than their peers who plateau at lower levels.

And I was looking at that, and then you see what was actually going on, and sort of saying, “Gosh, all these forces are pushing the opposite direction of that in the United States.” In Norway, which is like is, for me, probably the best sports country in the world per capita right now. There’s an HBO real sports on that’s showing they have embraced this stuff and changed their sports development pipelines.

But when I was living in New York until recently, there was a U7 travel soccer team that met near me, and I don’t think that anybody thinks that six-year-olds can’t find good enough competition in a city of nine million people to travel, right? It’s just that there’s these other forces at work, like those kids are customers for whoever’s running that league. And so, all these other forces militate against what we know about optimal development.

Pete Mockaitis
Okay. Well, so then what do you think is to be done in terms of if you’re a professional in a workplace and you want to develop well and over the long haul such that you have a fruitful career and rise and achieve all of your career dreams? What are some of the key things you recommend folks do?

David Epstein
Yeah, so let’s say you want to be an executive, which I think a lot of people would like to be at some point. LinkedIn recently did some research at looking at what were the best predictors of who would become an executive, and they have these incredible sample silos so they did this in a half a million members. And one of the best predictors was the number of different job functions that an individual had worked across in an industry.

And so, I think our intuition is to say, “Pick a job function and stick with it and drill into it and carve your niche and get specialized.” But, in fact, these people who sort of probably developed a more holistic view of their industry and how to integrate different types of skills are the ones who go on to become executives. And so, they are getting that breadth of training. And so, when it comes to having to do these more complex problems, they’re probably better equipped.

So, LinkedIn’s chief economist’s main advice was, “If you want to be an executive, work across more job functions.” And I think that’s good advice but I think you can do things short of that in a lot of ways. Like, learn what your colleagues do, learn more functions at your own work, because our natural inclination is to settle into our competencies. And as we settle into a rut and we get competent enough, I was talking to the economist Russ Roberts, he said it’s a hammock because it’s comfortable that’s why we don’t get out of it. And I was thinking, I want to make a weird analogy here.

Pete Mockaitis
Oh, please.

David Epstein
When I was getting into my last book, I didn’t write about this, but I was reading some scientific literature on speed typing, okay? How fast is speed typing?

Pete Mockaitis
Yeah, I’ve been looking into speed typing. Continue.

David Epstein
Really?

Pete Mockaitis
Well, yeah, I had a recent guest talk about how that’s one of the top skills you can use to sort of accelerate your performance in all kinds of things because a lot of typing that’s going on. And I’m a fan of the website Keybr I think it is, which sort of helps you get fast at typing fast. So, anyhow, my interest is piqued. Please continue.

David Epstein
Okay. So, yeah, so the idea is we all, like at first when you’re learning typing you make a lot of improvement and you get to whatever you get to, 60, 70, 80 words a minute, whatever you get to. And then you plateau and we pretty much all stay there at very good but not great. And it turns out there’s all these strategies that you can use to get like twice as fast, and they’re not even that complicated. Things as simple as you’d use a metronome, you take it up a little bit, and keep up with it even if you make mistakes, whatever.

There’s a bunch of strategies to get like twice as fast. But what it suggested to me is that our natural inclination that just experience will get us to a certain point but then we stop naturally improving just with experience. We sort of settle into that level of performance. And I think that’s kind of true of everything.

And so, we’re in danger as we get more experience and get more comfortable of not developing new skills anymore. We have to try new things. And I think that’s good both because it can get you off a plateau. When I was on a plateau stuff at writing this book, I decided to take an online fiction-writing course and it worked beautifully to help with the problem I was stuck with.

And so, I think it works because it can help get you off a plateau, but also one of the other main ideas in Range is this idea of match quality, which is the degree of fit between an individual, their abilities, their interests, and the work that they do. And good match quality turns out to be very important for your motivation, your performance, and the only way to improve your match quality, it turns out, is to try some things and then reflect on those experiences and keep sort of pinballing, doing that, and with an eye toward improving that match quality.

So, like the Army, for example, has created a system called talent-based branching where they were kind of hemorrhaging their highest potential officers since basically the start of the knowledge economy where those young officers could learn skills that they could laterally transfer into other types of work. And, at first, they just threw money at those officers to try to keep them, and that didn’t work at all. The people who were going to stay took the money, and the people who were going to go left anyway. That has a half a million dollars.

And then they started this thing called talent-based branching where instead of saying, “Here’s your career track. Go upper out,” they say, “We’re pairing you with this coach-type figure and here’s a bunch of career tracks, and just start dabbling in them, and your coach will help you reflect on how did this fit with your talents and your interests. And we’ll do that so we can get you better match quality.” And that’s actually turned out to work better for retention because when people have high match quality, they want to stay. There’s a saying that I quote a research in the book, saying, “When you get fit it will look like grit because if you get a good fit, people will work harder.”

Pete Mockaitis
Well, I’m glad you brought up grit because that’s something I want to talk about. You say that there could be a problem with too much grit. What’s that about?

David Epstein
So, I think for listeners who maybe have probably heard the concept of grit, I’m guessing. But the psychological construct came out of this survey where it started as a 12-question survey where half the questions were points for resilience basically and the other half for consistency of interest. And so, you lose points if you sometimes abandon a project for another one or I think you change interest, and things like that.

And the most famous study, what was actually done on cadets going into West Point, so future Army officers. They were trying to get through what’s called east barracks, that’s the U.S. military Academy’s six-week orientation where it’s physically and emotionally rigorous. And grit, that survey turned out to be a better predictor of who would make it through these than more traditional measures that the Army used. And although most people make it through, which is great, but in the study. I feel like Angela Duckworth and her colleagues, I’d give them a ton of credit because some of the critique I write about in the book comes like directly out of their own papers and it’s kind of like lost in translation, I think, where those people in that study were highly pre-selected for a number of qualities.

Pete Mockaitis
Absolutely. Got to get that Senate recommendation, Congressional letter. That ain’t easy.

David Epstein
That is what statisticians call restriction of rank problem. So, if you’ve truncated a lot of variables by selecting a small group out of humanity, so it makes the other variables exacerbated. But they were also pre-selected for this very short-term six-week goal, right? And life isn’t a six-week goal. So, when we looked at the longer timeline, again, like half of these people basically leave the Army almost the day that they’re allowed.

And so, high-ranking Army officials said, “We should defund West Point because ‘it’s an institution that taught its cadets to get out of the Army.’” And that’s not the case, right? And those people didn’t just lose their grit. It’s that they learned some things about themselves, which tends to happen in that time period, the fastest time a personality change in your life is 18 to your late 20s, but it continues changing faster than people think over your life, and they decided they wanted to go do something else.

That’s why throwing money at them didn’t work where talent-based branching did because it’s giving them some control over their career path and their match quality, and trying things and then changing direction is basically essential to improving your match quality. And if you’re not willing to do that, then you’re just hoping for luck in your match quality. And I think if we thought of our careers the way we thought of dating, right, we would never tell people to settle down so quickly.

Pete Mockaitis
“Just stick with that gal. She’s great.”

David Epstein
For some people that might be a good idea.

Pete Mockaitis
“You have four dates. Don’t quit.”

David Epstein
I thought I was going to marry my high school girlfriend and at the time that seemed like a good idea. And then I had more experience in the world, in retrospect that wouldn’t have been a good idea. And I felt the same way in my approach to jobs. Some jobs I thought I was going to stick with, I thought I was going to be a scientist. In retrospect, that wasn’t a good idea for me, but I didn’t know that until I tried that stuff.

Pete Mockaitis
And so, I’m intrigued then when it comes to sampling, I’d love it if you could share some of your favorite kind of tactical tips with regard to, “How can I get a lot of sampling going?” So, you talked about, “Hey, talk to work colleagues who are in a completely different functional area. Maybe check out an online course.” What are some other means of sampling?

David Epstein
Yeah, I kind of take this approach from someone’s work I love that resonated with me because I had career change, or changed directions several times, from a London business school professor named Herminia Ibarra. And she has this quote I love, “We learn who we are in practice, not in theory.” Basically, what she means is this psychological research shows that we’re not like so great at intuiting our own talents and interests before we have a chance to try stuff, we actually have to try the things, and then learn about ourselves. Act and then think, instead of think and then act, as she says.

And so, for me, I kind of started a book of experiments where just like when I was a science grad student, I’ll say, “Here are my skills now. Here’s some things I want to learn. Here are things, some weaknesses. Here’s my hypothesis about how I might be able to work on this.” And then I’ll go try something and see if that works.

So, again, I mentioned this online fiction-writing class I took, right? So, I got stuck in structuring my book, and I needed to do something different. And so, I go take this class, and among the things I was made to do was write with only dialogue, and write with no dialogue at all. And after doing the no dialogue at all, I went back to my manuscript and stripped a ton of quotes and replaced them with my description because I realized I was unconsciously coming from usually doing shorter-form types of things. I was leaning on quotes to convey information in a way that is not really good writing. And that’s not even the improvement I was looking for. But just getting out of my normal mode of doing things gave me this huge advantage.

And so, I try to do that regularly. Like, people might be familiar with this research “The Strength of Weak Ties” like your new job usually comes not from the people core in your network because they’re kind of doing this, you know those options already, and a lot of them are doing things similar to you. It comes from these people that you are several degrees away from but you can get connected to.

And that’s what Herminia Ibarra’s work shows, that when people find better career fits, it always comes from some key whole view, like they take some class, or they go to some event, or they meet someone at a dinner party and sort of ignites an interest, and then they start testing it little by little, getting in a little more and a little more until sometimes they make a full transition.

And so, I’m constantly doing those experiments with my book of experiments. So, I think everybody should constantly be doing this, “What do I want to work on? Here’s my hypothesis for how I could do that. I’m going to go try that thing.” Then reflect on it and put it in your notebook and keep going forward. And I think even keeping that, what I call that book of experiments, prompts me to constantly be doing that in a proactive way, whereas there was a period when I was at Sports Illustrated, for example, where I very much settled into something I felt come to that and just did over and over for a while, and took a while till I realized, “Gosh, I’m actually not adding to my skills here.”

Pete Mockaitis
And I really like that just sort of the fun exercise you mentioned with the writing, with regard to all dialogue and no dialogue, and then how that filters in forever. And that reminds me, boy, back in my AP, I guess, English composition or rhetoric course in high school, our dear teacher Judy Feddermier, that was sort of like each week that was the challenge. It was a different kind of a challenge associated with the writing, like, “Okay, this time you are not to allow to use any to be verbs. No is, no are, no was, no were.” I’m like, “This is crazy.” And I just used one, “This is crazy.”

And so, but sure enough, I was like, “Yeah, this writing is a little awkward,” but it’s what you sort of kind of back to being able to use some. You realize, “Oh, boy, having fewer of them sure sounds better in terms of more active and exciting and lively than a bunch of is’s and are’s.”

David Epstein
Yeah, and I think it sort of just gets you out of that. Because the interesting thing is and sort of almost like troubling thing to me when I did that with the no dialogue, and went and changed my manuscript, was that until then I didn’t realize that I had been kind of unconsciously doing something I’d gotten used to. And it took doing something different for me to think about that which is annoying. I wish I were just like perceptive enough to realize that without having to get kind of knocked out of my normal mode but, really, I wasn’t.

Pete Mockaitis
And so, I guess, I’m wondering then, in the whole universe of essential skills you might choose to start experimenting and dabbling in to add to your repertoire, is there a means by which you think about prioritizing them? Or is there just sort of, “Hey, there’s a glimmer of interest here. Let’s see what happens”?

David Epstein
Yeah, that’s a good question. Usually, I kind of always have some project or other that’s either in some stage of development, and my projects tend to be quite different. And so, there’s usually something related to my project that’s either like an area of knowledge maybe that where the project is kind of driving those in some way, where it’s I know I need to, that this book is going to be the biggest structural writing challenge I’ve ever had, therefore like I need to improve my skills. So, usually it comes out of something that I’m otherwise doing, and realizing what’s the new part of that challenge.

So, I will say, when I’ve taken on these bigger projects, like my first book was the hardest structurally to organize all the information writing challenge I ever had, and this book was much harder than that one. And so, I think the one thing I’ve done a pretty good job of is taking on these projects that are kind of in the optimal push zone where they’re not so over my head that I simply can’t do it, but they are definitely stretching me to the point where I have to think about learning new things.

Pete Mockaitis
Yeah, that’s fun. And I’m also wondering about sort of things that you hate. So, one approach is there’s a glimmer of interest or sort of what skill is necessary to develop there. And I’m wondering about because when you’re talking about in terms of sort of this inefficiency or doing a wide breadth of things such that it’s more frustrating and less fun sort of the in the early stages, but then you have some cool capabilities later on as a result of doing it.

I guess I’m wondering to what extent would a chasing after skills that I’m just currently very bad at, I’m thinking about sort of home improvement and being handy type skills right now, so kind of the opposite of intellectual, “Hey, we’re having rich conversations and thinking about the themes and summarizing them well, and marketing and reaching audiences,” like all that stuff is like very different than, “Okay, I got to drill and I’m trying to make this thing go there and not make a huge mess.” Is there a particular value in doing stuff you hate?

David Epstein
I don’t think you should necessarily do it over and over if you hate it unless it’s really essential to something you’re doing. So, when I first started doing some lab work en route to what I thought I was being a scientist, my expectation was that I would love it and this was what I would do for the rest of my life. And what I found out was that was not necessarily the case, and that was an important thing to learn.

And, conversely, I’m a fairly new homeowner, and the last thing I would’ve thought I would ever be interested in was plumbing, for goodness’ sake. And, it turns out, it’s kind of interesting actually. Like, we had some stuff we had to fix and I started to find this sort of interesting. So, I don’t think you should do anything with plumbing if you hate it, but I do think you might find things that you a priori would think you wouldn’t really like, then when you actually try them might be more interesting than you thought. And, vice versa, things that you expected to love that maybe not so much.

Pete Mockaitis
Interesting. So, it sounds like it’s worth at least an hour or two to see what happens.

David Epstein
One of the things I write about in Range is a so-called end of history illusion. This is psychology of finding that we all realize that we, based on our experiences and everything, we have changed a lot in the past, but then think we will change very little in the future. And we do this at every time point in life, if we say we change a lot in the past, and then proceed to underestimate how much we’ll change in the future. So, it leads to all these kinds of funny findings.

So, one just sort of humorous one is, because people underestimate how much their taste will change, if you ask people how much they would pay for a ticket to see their favorite band, their today favorite band to 10 years from now, the average answer is $129. And if you ask how much they would pay to see today their favorite band from 10 years ago, the average answer is $80, because we underestimate how much our taste will change.

And the thing is personality actually changes over the entire course of your life, and one of the predictable changes is as you become older, your openness to experience, which is one of the big five personality traits, declines. But doing new stuff that you’re not used to can actually stop that. So, there are these studies where older people are in that decline phase, and this is a trait that we know is very much correlated with creativity. And these old people were trained on things like certain types of puzzles, okay? And even if they didn’t get better at the puzzles, they became more open to experience. And so, I think there’s also these personality reasons that are associated with creativity to do stuff that is just outside of anything else you’re doing if you want to stem that decline of openness to experience.

Pete Mockaitis
Well, I think what’s interesting about that is it might be hard to even dream up or conceive like what is that thing because it’s so not in your current world. Do you have any tips on how to kind of spark that prompt or stimulus in the first place?

David Epstein
For me, and this has been a long-running thing is I go to libraries and bookstores because those are places where I find interests that I didn’t know I had. And that’s why I value those places so much because, nothing against Amazon, but, yet, the algorithm works in a way that it sends me things I’m interested in and that I think I’m interested in, and it doesn’t send me the things that I don’t know I’m interested in basically.

Pete Mockaitis
Right.

David Epstein
And so, when I do this more natural browsing which, by the way, I consider the willingness to go to libraries now like a competitive advantage for me because I think people don’t do it anymore. But those are the places where I find these things that I did not know I was interested in, and that’s why I really value them. That’s why I make sure I go to those places instead of just only ordering my reading material, and I’m a big reader on Amazon.

Pete Mockaitis
Yeah, I’m a huge fan of libraries and, boy, now, you’ve got me kind of excited just to see what would happen if you just went kind of blind into a stack, grabbed a book, and say, “I’m going to read six pages and see what happens.”

David Epstein
When I go into like a local bookstore or something like that, I don’t go, like if I really need a book right away and I know what it is, I will order on Amazon, and if I really need it quick, I’ll have it on my Kindle. But when I’m going into like bookstores, I’m not going for a particular thing. I’m going to look around and I always end up with something that I didn’t really expect.

Pete Mockaitis
That’s cool. Well, can you tell me, if folks are inspired, they’re thinking, “Yes, David’s Range that’s what’s up, I’m all about it. I want to get some more skills, be more interdisciplinary,” are there any kind of watch-outs or warnings or mistakes that are associated with this endeavor?

David Epstein
Well, I think people are probably pretty aware of the jack-of-all-trades-master-of-none sort of syndrome. Like, you don’t want to get cast as someone who doesn’t know anything. And I think it’s actually pretty culturally telling that the end of that phrase, that adage, jack of all trades master of none, is oftentimes better than master of one, but we’ve totally dropped that part and I don’t think we even know it. And I think that’s because there’s sort of this bias against breadth. And so, I do think there’s that danger of signaling to other people that you don’t really know anything about anything.

Pete Mockaitis
It sounds dangerous.

David Epstein
Yeah, and I think that’s actually one reason why. So, I was just at…maybe a lot of people have heard of Motley Fool. You know Motley Fool? I was just at an event of theirs, and there was a survey on a video screen and the audience could vote with their phones. And the survey was, “What do you think is the average age of a founder of a breakout startup on the day of founding, not when it becomes a breakout?” The choices were 25, 35, 45, 55, and the overwhelming favorite was 25.

And the answer is actually based on research from MIT and the Census Bureau is 45 and a half. But we sort of think of this, you know, Mark Zuckerberg, when he was 22 and famous, he said, “Young people are just smarter.” Like we think of Tiger Woods, even though that’s not the normal typical model, and Mark Zuckerberg, it’s these very dramatic stories of youthful precocity that we think of as the norm, but actually the people who become these really successful entrepreneurs usually bounce around a fair bit first.

And I think what a lot of them end up doing, I describe people like this in Range, is they get this mix of skills that maybe other people sort of look down upon, but it leaves them with this intersection of skills that creates new ground where they’re not in direct competition with someone. They’re trying to do something new, and they have to create their own ground, and they often become entrepreneurs, sometimes because they have to. And that can be really good but it can also be really challenging because you can kind of end up, and I think especially so, in this year of LinkedIn, which I think is a great tool, but also allows HR people to make a much more narrowly-defined job and still have a ton of candidates.

And so, in Range I talk about the work of Abbie Griffin who studies so-called serial innovators who make these repeated major contributions to their companies. And her advice to HR people is basically, “Don’t define your job too narrowly because you’re going to accidentally screen these people out because their traits are like they’ve often worked across domains, they have a wide range of interests, they read more widely than other colleagues, they have a need to talk to more people in other disciplines, they like to use analogies from other disciplines, they often have hobbies that seem like they might be distracting,” but that those are the traits of those people, and her concern is that HR people will see them as scattered and not as focused on any particular area.

So, I think the real concern is of the signal that might be sent to people who are in a position of making personnel decisions.

Pete Mockaitis
Absolutely. Well, thank you. Well, David, tell me, anything else you want to make sure to mention before we shift gears and hear about some of your favorite things?

David Epstein
I think specialization made a ton of sense when we were in more of an industrial economy, when people were facing similar challenges repeatedly and that was when those Army officers did not move outside of the Army with nearly as much frequency because other companies, specialists were facing the same challenge, and they were ahead, and you can’t catch up. But in the knowledge economy, some of the patent research I looked at in Range shows that it’s basically just since like the late ‘80s forward where the contributions of more generalists inventors.

So, in this research, the generalists are defined as people, their work is spread across a larger number of technology classes, as class is a patent office, whereas the specialists drill more into a small number or a single technology class. And both of these types of people make contributions, but the contributions of those people who are broader have been increasing with the knowledge economy.

And so, I don’t think this has always been true that generalists have these special, or broader people have these special contributions to make, but I think it’s sort of a function of the fact that with our communication technology, information is rapidly and thoroughly disseminated. And there are many more opportunities, for combining knowledge in new ways as opposed to just creating some totally new piece of knowledge.

Pete Mockaitis
Yeah, that makes sense. Now, could you share with us a favorite quote, something you find inspiring?

David Epstein
I love that quote from Herminia Ibarra, “We learn who we are in practice, not in theory.” That’s one that’s like really stuck in my head because I don’t totally know what I’m going to do next, and I’m thinking about things. And so, that’s really affected the approach that I’m going to take.

Pete Mockaitis
All right. And how about a favorite book?

David Epstein
Right now, I would say that my favorite book, gosh, I read a lot so this changes from time to time, but right now, I would say my favorite book is probably War and Peace, the Anthony Briggs translation, so I read multiple translations when I got really into it. And I didn’t realize, I was just reading it because like I was going through this website that aggregates all great book list, and I was trying to just like go down some of the greatest books.

And it is a novel, in the form of a novel, it’s actually Tolstoy’s refutation of the great man theory of history, and he uses Napoleon as the main character, and argues, and he does like some journalistic reporting on those events, and argues that, well, Napoleon was really an effect not a cause of these larger forces basically.

And so, he had these historical essays. And the story, his writing is amazing. But I also found that argument really interesting, and that led me to read this essay about a philosopher Isaiah Berlin based on War and Peace where Isaiah Berlin used these two types of characters he analyzes in War and Peace the foxes and the hedgehogs. The hedgehogs know one big thing, and the foxes know many little things.

And those hedgehog and fox constructs were then borrowed by Philip Tetlock, the psychologist, to do the work that’s featured in my chapter 10 of people who develop the best judgment about the world and about political and economic trends, who know many little things instead of one big thing. And so, it was really cool, you know, that research I was already interested in, to see in War and Peace sort of where those ideas of the fox and the hedgehog via Isaiah Berlin’s philosophy as it where it came from. So, not only did I enjoy the book for its own right, but it really made me think about some modern research in an interesting way.

Pete Mockaitis
And how about a favorite tool, something that helps you be awesome at your job?

David Epstein
Oh, my goodness. I would die if I didn’t have Searchlight on. That’s why I have to be a Mac user because I basically, the organization system I use is writing lots of words in various things that I think I would search if I wanted to find it. And so, I’d probably use Searchlight 500 times a day.

Pete Mockaitis
And a favorite habit?

David Epstein
Running, if you count that. I’m a very avid runner.

Pete Mockaitis
Oh, sure thing. And is there a key nugget that you share often that tends to get sort of quoted back to you frequently?

David Epstein
In my first book, The Sports Gene there’s like I did some data analysis of body types, and this one part that mentions that if you know an American man between the ages of 20 and 40, who’s at least 7 feet tall, then there’s a 17% chance he’s a current NBA player. And, yeah, people mention that to me a lot.

Pete Mockaitis
I just think it’s funny that a very specific numerical tidbit is what people are sticking with.

David Epstein
Yeah, I tell you, I’m really bad at predicting at things for my own books that people are going to latch onto versus the things that I latch onto the most. It’s kind of an interesting experience.

Pete Mockaitis
And if folks want to learn more or get in touch, where would you point them?

David Epstein
DavidEpstein.com is my website, and I’m davidepstein on Twitter.

Pete Mockaitis
And do you have a final challenge or call to action for folks seeking to be awesome at their jobs?

David Epstein
Yeah, I think if I can really talk to someone it would be managers, and say, “Do your own form of talent-based branching where you allow people to explore some of their other interest and talents, and help them reflect on those experiences.” I was on the podcast for The Ringer, Bill Simmons. He runs probably the most popular sports podcast in the world, and he used to be ESPN’s most popular writer, then he did something on HBO and that kind of failed. And now he started his own company, and it’s one of the happiest workplaces I have ever been in.

And one of the interesting things was people who were hired to edit like online articles, some of them have become like seriously famous in the sports world podcast personalities with huge followings, and that’s because once they’re in that company, he’ll say like, “Okay, come try on a podcast for a little bit and see how it goes.” And it seems like people have an opportunity to basically try their hand at whatever the company has to offer. And a couple of the people who came in, in these more kind of quotidian jobs have become like famous, and it was a happy workplace. So, I think he’s really onto something with sort of letting people try their hand at things in a way that like doesn’t really damage anything too much if it doesn’t go well.

Pete Mockaitis
That’s cool. Well, David, thanks for this. I wish you tons of luck with Range and all your adventures.

David Epstein
Thank you very much.
