Chapter 1: What sparked Susan Dominus's interest in sibling dynamics?
So I think it started when I was a young child, and my parents used to go away pretty often and travel for work. And when they did, I would stay with really close family friends. And you may know that when you stay with a family, you really get to know them and their culture in a way that's different from your own family. You can really see all these big differences.
In one family I stayed with, the kids would do these very elaborate math problems, like at the table, you know. At the dinnertime? At the dinner table. One, the father would say, so Daniel, a plane is leaving Chicago traveling this many miles an hour and another one is leaving New York. What time would they cross paths in wherever, you know?
Oh my God, what are you thinking when that question comes across the table? I loved it.
It was like a show for me. I just loved it until they asked me that question one day and I burst into tears.
Is it safe to say that was not the dinner table dynamic at your house?
No, my father's very proud of the one rule we had at the table, which was that you had to chew with your mouth closed. And that was firmly enforced. But I became what I think of as kind of a familyologist. I got very interested in how family cultures differed and how it affected the kids in those families and their outcomes and who they were likely to become. Mm-hmm.
And fast forward, I become a journalist. Perhaps not surprisingly, a lot of what I cover as a now adult familyologist is family dynamics. I do a lot of reporting that involves twins and nature and nurture. And I really got interested in doing even more research into this topic. I ended up undertaking a book, which was going to be about the nature of families of high-achieving siblings.
Mm-hmm.
And I went into the book fully expecting that I was going to hear these stories about parents who had these extraordinary ways of doing things and they inspired and motivated their kids. And instead, what I found was that although parents matter, certainly the parenting effect is actually probably smaller than we think.

Chapter 2: How do siblings impact children's development?
Thank you, Michael.
I wonder if you can illustrate how it actually works that siblings influence the direction of that arrow.
Yeah, I was curious about that myself. How did that work? And one way that I got at it was by going deep with a couple of families and really spending time with them, really understanding the sibling dynamics and how they recalled their childhoods and these really influential moments. So one of the families that let me into their lives was the Groff family. This is a family of three siblings.
Lauren Groff is this much lauded influential novelist. Her sister, Sarah True, is an Olympic triathlete turned Ironman champion. I know. And then they have a third sibling who they also know. He's the really impressive one, Adam. And he is a serial health care entrepreneur who's done extremely well doing good with innovative health care solutions.
Chapter 3: What conclusions did Susan draw about sibling effects?
Okay, and what do you find from the Groffs?
You know, the Groffs embodied very neatly a concept that's known as differentiation. Okay. This is the idea that kids are trying to find a niche as they're growing up. And so if one sibling is doing one thing, whether it's conscious or not, another sibling might go in a different direction or their parents might even push them in a different direction.
So you can see where this ended up in the Groffs in that they all have careers that are... Wildly different. Wildly different.
And then what do you come to understand about how, and this seems important, consciously or unconsciously, the Groff siblings... exerted a differentiating force on each other? Because that seems like it would be not something you would necessarily ever consciously intend to do.
I think it happens all kinds of ways, actually, but the person who's most explicit about it was Sarah, who's the youngest of the three siblings. Sarah had these two older siblings who were very, very academic, and she felt that if she couldn't keep up with them, that was on her, she said, and that her desire to keep up with them was all about her relationship to them, much less her parents.
So, first of all, that was interesting to me. It wasn't about pleasing her parents. Right. It was about keeping up with her siblings and being worthy in their eyes, I think. But she also felt that she couldn't keep up with them academically. And she says that she thinks she made a conscious choice to go into sports all in because that was a domain where she knew she could excel.
But even more than that, she knew that Lauren wasn't that interested in it. And so, you know, so she felt like— The lane was free. The lane was free. Yeah. And this effort that Sarah has to, you know, find her own lane really comes to head when she's 14 years old. And she tells her parents that she wants to swim the length of the nine-mile lake that's right outside of their home.
And the family all sort of, you know, they're dreading this. They don't think she's going to be able to do it. But they're like, OK, let's go. Dad rose. Brother's in the sailboat with him, too. And not only does she swim the length of the lake— But she actually broke the town record for men and for women. And that record still stands.
And they all agree that that was a really defining moment for Sarah. And I think she kind of came into her own and realized, ah, this is who I am and what I'm going to keep doing. And ran with it and swam with it and became this incredible triathlete. And it's really interesting because there's a lot of research actually that suggests that younger siblings are overrepresented in sports.

Chapter 4: How do the Groff siblings exemplify sibling differentiation?
Just explain that because everyone listening is going to want to understand why that is.
Well, there's different theories about it, but the one that rings the most true to me, I'll just say, is that when you're an only child, you know, your parents just shower you with a level of attention and cognitive enrichment.
And they have more of that attention.
They have literally more hours in the day to spend on that first child than they do when the second and the third come along. By the way, I should emphasize that these effects are small and they are also on average. So it does not mean that this is necessarily true for your family, dear listener, or dear youngest child, of which I am one. But it does mean that on average, this is what we see.
And so... When you have an oldest child typically being the most academically strong, then you see this differentiation, which is that younger children are sometimes more drawn to sports or they compete a little bit harder in sports in order to define their niche and find their way and have space where they can excel.
And then you actually do see in some research that younger children are overrepresented in elite sports.
That's fascinating. And clearly that seems to be what happened with the youngest of the Groff siblings. What about the middle Groff child? What was her experience, Lauren?
So what I see in Lauren is something that's a little bit different, which is you can see in Lauren, and she's actually also quite self-aware about this, how a sense of competition with her brother was really fueling her. I don't think her brother was even aware that there was a competition, but she felt like she wanted to prove something to him.
At one point, she felt, she told me, that a huge part of what motivated her to write big, bold, feminist literature was the frustration that she felt with this all-knowing older brother. Wow.

Chapter 5: What is the spillover effect among siblings?
Chapter 6: How does family background influence sibling dynamics?
Chapter 7: What is the role of competition among siblings?
That was true in a way for sports as well. So Yi, the oldest of the brothers, was a very accomplished wrestler. But it's not that Gong then chose some other sport. He didn't go in a different direction. He, too, became a wrestler. And so he benefited from his brother's expertise, and they were kind of consolidating forces. There's like this symbiosis.
And, you know, you see these kinds of so-called spillover effects. They influence each other in very collaborative ways.
And it sounds like in this collaboration you're describing, the Chen siblings are building off one another, each one hoping that the next will do at least as well, if not better, than they did, either academically or athletically. That, you're saying, is the spillover effect. And it really does feel quite different than the more competitive, tinged idea of differentiation.
I mean, it certainly looks like one mechanism of the sibling spillover effect. It's the opposite of competition. It's working together and influencing each other and making each other in some ways more similar, which to them was about making each other better, basically. You really see it in their youngest sibling, Devin.
They had all gone off to college themselves or maybe were even out of college by the time he was applying to schools. And they actually felt a little bad for him that he wasn't benefiting much. for what they had provided for each other when they all lived in the same home at the same time.
There wasn't enough spill left to spill over him.
Yeah, exactly. And so they would, you know, conference call with him, and they actually formed a reading group to make sure that he was reading. They were picking books to make sure that he was keeping up with that. And then when it came time for him to apply to college, they actually divided up the tasks.
One of them took over SAT prep, and one helped him with his essays, and one helped him keep on top of applications and staying organized. Wow. And this is one mechanism of how the spillover effect works. It's Devin presumably wanting to live up to his siblings' academic success, but it's them also really sharing their resources with him.
Where does Devin end up going to college? Which, of course, makes me want to know what happens to all four of the Chen siblings in terms of their career.

Chapter 8: How can siblings influence academic success?
And does that mean that younger siblings can spill over to older siblings? Yes, that is what that means. Hmm. So now that we've talked through these two distinct factors, but seemingly related forces of the spillover effect and differentiation between siblings. I wonder what you have found in your reporting on how controllable any of this is.
Parents like to think, and you hinted at this earlier, that they exert some level of influence over this kind of thing. Can they? Do they? Or is it ultimately out of their control?
You know, I think that parents think they have more control than they actually do over so much. And trying to really change one child is kind of like checkers. And then the idea that you're going to try to actually manipulate some complicated interaction over many years among multiple siblings, like to me, that's just like playing chess with a blindfold on.
Yeah.
You know, there's some common sense things that I think parents aspire to, which is not to compare too much. And if they have the resources to let children, you know, pick their own passions and foster them. But I also think that some of the things that drive sibling relationships, such as competition and rivalry, you can manage it, but you can't necessarily control it.
I don't think we can end this conversation without asking you about your own siblings and your relationship to them, with them. Is it a story of spillover? Is it a story of differentiation? Is it a story of something else entirely?
I think in terms of personality, there's some differentiation there. But it's also, I think, this idea of the arrow being launched and the sibling helping it land somewhere. I really see that in my own family because my parents definitely valued hard work. That was a huge value in our household. But my brother was the person who came to me when I was 14.
and said, why don't you join the high school newspaper? He was at college at the time. And I said, we don't have one anymore. It disbanded. And my brother then launched into a big lecture about the decline of democracy without a free press, and it was pathetic. And he kind of rallied me to try to restart the high school newspaper. And I was a pretty passive kid.
I spent most of my time reading in a room. But my brother knew me well enough to know. He knew before I knew that I would love doing journalism. And I think if my parents had suggested it, I would have rolled my eyes and thought it was something they thought I should put on my application. But also, God bless my parents, they were really laid-back people.
