Dr Audiey Kao: Dr Krieger, thanks for being a guest on Ethics Talk today. [music fades out]

Dr Nancy Krieger: Very much appreciate the invitation. Thank you.

Kao: So, compared to getting my medical degree, getting my PhD was a more solitary pursuit. For example, dissertation defenses are usually sparsely-attended affairs. But I've read accounts that it was standing room only for yours at the UC Berkeley School of Public Health. Attendees were apparently taking notes as fast as they could because they didn't want to lose any of it. Your doctoral thesis was entitled Race, class, and health: Studies of breast cancer and hypertension. Can you tell our audience about the main findings of your dissertation research and how it's set the groundwork for your interdisciplinary scholarship that has reimagined our understanding of the determinants of population health?

Krieger: Thank you very much. Yeah, it was fun doing my dissertation defense quite a while ago now. And I must say one of the interesting things with COVID-19 right now is the shift to move to a virtual defense of some of my students. And that's actually allowed a whole lot more people to attend, which has been very nice and makes the dynamic, very different.

Kao: That's interesting.

Krieger: But not that it's great. It's still much nicer to do it in person, however. But it's good to have the expanded audience possibilities. So, my dissertation came out of a time I was getting my, obviously, doctorate in epidemiology, social epidemiology at the time. I'd gotten a Master's before. And while doing some of the work in my Master's thesis, I was very interested in the questions of racism, class, and health in many different ways, partly occupational health background, partly other things. But I got drawn to the question of particularly breast cancer and was really appalled back then to discover that in the cancer registries—as is still the case. But it's different now a little—you could get data on race/ethnicity, but there's no socioeconomic data. And obviously, you end up that way with only racialized statistics. And you can't understand the extent to which racial inequities and economic position because of social injustice and structural racism are affecting what's going on. But you also are engaged in those debates. Well, is it only a matter of class? How does racism then fit in in the parts that are not economic?

So, back then, I had done—and this is critical for my dissertation—I'd started getting involved in trying to figure out, well, if you knew something about where people lived, you could connect to what their census tract information was or the census block group information. And I know that this was at a time that was long before any of this was easily digitized. So, to geocode addresses, one sat in your room with the radio on and just cut it with an address book. So, for my dissertation, I built on that, and I worked with the cancer registry to actually do two things. One was to actually geocode records and to look at what was going on with the incidence rates of breast cancer amongst particularly Black and White women in relation to also their census tracts' socioeconomic characteristics. I also wanted to validate that methodology, and that meant that I got to do a survey. And I worked with the cancer registry staff to do that survey.

And in doing that survey, I also decided that it made sense, that I was very struck by the fact that there seemed to be virtually no studies—I mean, I could count them on one hand at that time—that were in public health and epidemiology that actually asked people about questions of their experiences of discrimination. And that made absolutely no sense to me. People asked about all other kinds of things. Why not ask about this?

Kao: Right.

Krieger: So, I put in questions. I built those in. And that led to the first development of the Experiences of Discrimination questionnaire that's become one of the more widely-used instruments. And that was the beginning. I did subsequent work to validate it. So, what then happened was being able to think about that also in relation to data around blood pressure and to start to do the initial work, to start to ask those questions, just beginning. Because I did a subsequent study a few years later after I graduated to start to really begin to ask the question, do people's self-reported experiences of racial discrimination in particular connect at all to what their profiles are in terms of cardiovascular disease, and in that particular case, hypertension? So, the themes came together in different ways around class, around racism, around gender. Those have been integral to my thinking since I started even thinking about doing anything in science. And they came together methodologically, but also important, they came together theoretically.

And what I would add is that I was doing this work at a time where that kind of what is now called intersectional thinking was actually not that uncommon. In fact, I was at that point already. I'd become involved in the mid-'80s in the National Rainbow Coalition was Jesse Jackson's work and was actually, for the 1988 presidential campaign, I was part of the National Rainbow Health Commission. And my role on that commission was actually to draft the AIDS platform for the Jesse Jackson campaign, which was very beneficial because it helped push to a more progressive stand the AIDS platforms of others.

Kao: Hmm.

Krieger: I was very much in the thick, where the framework is rainbow politics. The idea is that every stripe matters, but together they create something more. You don't lose what are the distinct issues, but you also understand the connection of issues. And clearly, what's also changed over time, which is nice, is that the rainbow notion most recently, for example, specifically in LGBTQ communities, has been expanded so that it's not just the rainbow flag anymore, but also includes colors of black, brown, and colors for trans around. And so, it's really important that that notion of rainbow becomes that much more inclusive.

But just to say that although it was unusual that I was doing that work in the frame of epidemiology, of thinking theoretically and methodologically, how do you understand the issues of racism and class in relation to gender and also—although that was not directly part of the dissertation—sexuality at that time, how did these things come together to affect population health? That kind of thinking was feasible. Other people were asking those questions. It just needed to be brought more firmly in a centered way into the field itself.

Kao: Yeah. So, in reflecting on your scholar activist work, I'm reminded of the aphorism that health is wealth. So, if you're sick, your health may not be retrievable no matter how much money you spend. On the other hand, the work that you just mentioned has empirically demonstrated that wealth is health. Or stated another way, income inequality is a leading contributor to disparities in health. So, as opposed to biological inheritance, your work has illuminated the health consequences of intergenerational transfer of wealth or what you've called societal inheritance. Can you explain this distinction between biological and societal inheritance? And what are its implications for social policy choices aimed at addressing racist policies like Jim Crow that have resulted in transgenerational harms and inequities in health?

Krieger: So, that's a lot in that question. [chuckles] What I'll start with is an understanding of what even is the idea of inheritance. So, the word itself, if we trace it etymologically, it refers to that which is passed from parents to progeny. And it was always in terms of physical property, actual wealth however it was reckoned in that society. But it comes from being the inheritors, the heirs, the people that are getting something by familial transmission as set up by the rules of their society. Because different societies and different political economies have different rules for inheritance.

So, what happened is it was until the 1900s, it was very much an economic social term. Then it got brought in increasingly by people that were working in genetics to think about one inherited something from one's parents, even though it wasn't exactly clear what that was, of the germplasm. So, in 1911, when Wilhelm Johansson coined the constructs—he was a Danish scientist—coined the terms of “genotype” and “phenotype” in a very classic paper that's very key to make incredibly clear that, yes, organisms may inherit. Clearly, gametes contain something that makes the next zygote or however whatever form of reproduction is occurring, that that's not the full story. Because the organism has to grow up and develop. You don't stay a zygote forever. You have cells that differentiate. You get, depending if you're a multicellular organism, you start to get different organs. Things must be changing, turning on and off genes. You're not expressing just 100 percent all the time in every cell. And so, he invented the concepts of genotype and phenotype. And we live our phenotype. That is all you ever see. There is never, you never see anybody's genotype.

Kao: Right.

Krieger: What we live is our phenotype. And he complained bitterly in that paper at the beginning of the false use, the misleading use really, of the word “inheritance.” Because it really misses the point that it's not a lump-sum thing you have, because it's part of what you are. But you are dynamically changed in who you become because that's the way people live phenotypes. That's the way any organism lives its phenotype. And it's an emergent property, which is why I think about living organisms as emergent, embodied phenotypes. So, from that standpoint, yes, different experiences, early life onwards, can have impacts that last across the lifetime.

And it's also to be understood, not just the personal lifetime one's, life course, but what historical generation you are. So, for example, to be age 50 now is not the same as being age 50 in 1950, for example.

Kao: Right.

Krieger: If you were born in 1950, if you were 50 in 1950, you were born in 1900. And this matters when you think about things like, for example, Jim Crow. So, Jim Crow was abolished by law in the mid-'60s, I mean, there's different Civil Rights acts that come into play, but from between ‘65 and ‘69, a, with regard to the Housing Act and all. And yet people that were born back then, people who were born in 1950, for example, they were in their teens when Jim Crow was abolished. They're alive now. They're older. What were those life experiences? That gets completely lost from a very ahistorical approach that doesn't think about what those impacts are. And I've shown in my own research, for example, it's mattered in terms of infant mortality rates, differences among Black, in terms of born in Jim Crow or non-Jim Crow states. It matters in terms of premature mortality now, and it matters in terms of what kind of breast cancer African-American women get in terms of whether estrogen receptor positive or negative. So, that's one thing.

But another way to think about the histories that come in across generations is we've just published two studies that add to the incredibly tiny body of work that looks at the implications of historical redlining back in the 1930s when the U.S. had first set up those policies that led to this redlining, whereby in the different cities that were evaluated, properties were assigned one of four kinds of codes to say how desirable they were for investment or disinvestment.

And one of the key criteria for redlining was these are places where you should not, according to the people that do the ratings, lend anybody anything for a mortgage. And they were therefore redlined. And they were, if you had any Blacks back then, it was referred to as Negroes very explicitly in the documents. If it was a multiracial ethnic population, if it was low income in any way, the language is often fairly derogatory that's in the appraisals that you can see online.

Those records, those maps only got recently digitized. They were lost for decades. They got rediscovered in the National Archives about two decades ago, only recently been digitized, two years ago. So, people are just starting to use them again now at work. And we've shown that those designations still matter from 80 years ago for risk of preterm birth in New York City and then also with work that we've just done in Massachusetts, cancer stage of diagnosis. And that's even taking into account contemporary characteristics of the areas where people live.

So, that's something which is important because housing, for example, is one of the main ways in which people in the U.S., except for the ultra, ultra-wealthy, have anything that resembles an asset.

Kao: Yeah.

Krieger: And if you don't have access to housing, you don't have access to wealth. So, that's really important.

And again, the empirical work is just beginning to be done. And there are probably now, what, still less than what I can count on my fingers of two hands published studies that have rigorously started to look. I think there will be more. I'm aware of more colleagues that are beginning to do the work. And it's not simple work. There's an awful lot of decisions that go into figuring out how to analyze these kinds of data.

But those are ways to start to think about that what matters is who one is, what one's own life course is, when one is living that life course, part of what historical generation, and what is true of your parents? What experiences did they have? It matters if they were in a state of being very impoverished when you were born. Why were they impoverished? These become chains of connections that become extremely important to understand, because it matters for accountability, and it matters for health now. It's not just a historical curiosity.

Kao: So, in economics, talking about socioeconomic status, but in economics, a state of efficiency where resources cannot be reallocated to make one individual better off without making at least one individual worse off is known as Pareto optimality. Economics seems to have played an oversized role compared to other disciplines, other social sciences, in shaping the thinking and approaches taken by today's policymakers. How can we better educate policymakers to a broader set of learned disciplines like social epidemiology? And how do you think that will affect public policy making?

Krieger: Every discipline has its sets of theories and debates in those theories, and it also has sets of methods and debates about those methods. So, I'm aware, for example, that a labor economist would give a very different definition, approach to talking about what some of the issues are with economic thinking and what they can contribute to understanding and improving policies that'll have an impact on health, than, for example, someone who's mainly interested in financial capital.

So, I want to be mindful of that and not paint with an overly broad brush, because there are economists who have been really crucial in giving insights into the unjust accumulation of wealth. Because to have an ahistorical, apolitical, acritical view of this is a transfer from this person to that person without considering how that transfer occurred, why there are inequities in the first place—they don't just come out of the sky—is very important.

I think it's very disturbing, for example, this weekend that the senator from Arkansas, Cotton, actually was quoted as saying that he's very angry at the New York Times for their series on 1619 in relation to the histories of enslavement in this country, saying that it just gives a false foundation to understanding the origins of this country. And he literally used the phrase that “slavery was a necessary evil.”

Kao: Hmm.

Krieger: Necessary for whom? Yes, for people that were benefiting from white supremacy, from owning slaves, and from the slave trade, but necessary for people who were enslaved? Generations of people who were tortured, lived in fear and terror under slavery? I don't think so. So, to ask about that kind of redistribution of wealth after wealth has been gained in ways that have fundamental injustice built in, to me, is a very different question than talking about redistributive policies where there's a sense that there was something that was not completely unjust, unfair, or not by ultimately horrific force that created the wealth divisions in the first place.

And in this country, you can't think about the health of different populations without a, thinking about who and what defines those populations. So, who defines what's Black and what's White? Who defines what's Indigenous, what's not? Where have different groups of Asian-Americans of many different kinds been classified or not as White, Asian, whatever? What the lawsuits are about that. What the laws have been about miscegenation or not. What the laws have been that define whether one is a property holder or not, entitled to vote or not. Populations also don't just drop out of the sky. They are socially shaped, historically defined, and reflect interests of the time that those groups are created. So, you can't think about any population's health in this country without knowing something about the history.

Kao: Yeah.

Krieger: I think what happens is that a lot of the work in my field, and in economics often, that is not very critical, doesn't deal with the actual complex histories that involve not only justice, but aspirations for equity.

Kao: Yeah.

Krieger: I think that the aspirational parts of recognizing what might it look like to have an equitable society are also important to keep an eye on and to see where policy change has effectuated that as well. So, I do think that having things only framed by economists, the other thing that I've found in a number of my interactions is that where I again come in as someone who's a social epidemiologist. Because I think about time in relation to embodiment and the ways people [audio drops] happens. So, it's not instantaneous. None of this is. And I understand that you carry your history in your body, everyone does, is not the way of thinking.

So, for example, that you see, you can quickly change things like, for example, access to health insurance. You can quickly change, for example, income transfers with regard to tax policy. We've seen an awful lot of that change in the past few decades, where the distribution is ever increased upwards and not downwards in terms of who's benefiting from what tax policy is. But you can't do that with people's bodies.

Kao: Yeah.

Krieger: You change a vaccination rate very quickly. But if someone—and this gets back to your very first question—if you've had adverse conditions, they're not all, especially from early life on, they're not all easily remediable in terms of fixing what the health problems are because they're part of you.

And there was a colleague once who was in a mix of both economics and government who wondered, well, do we really need, for example, if the laws are all saying that discrimination isn't supposed to happen, do we really still need to continue to collect things like race/ethnicity as a category? We understand that it's social, but if it's not really biological, why should you categorize it? And what I said to this person was, “Do a thought experiment,” which economists like to do all the time for their counterfactuals. And if you suddenly abolished 100 percent of all racial inequality in this country and you evened out all income and everybody was living in equally great homes and everybody, all of that, but you kept everybody in the same bodies that they had, would you expect health inequities to disappear overnight?

Kao: No.

Krieger: The answer is no.

Kao: Yeah. You know, we could spend I'm not sure how many hours of interviews talking about what you just discussed. And I think that this notion, that thought experiment is quite, is one that I think our audience will need to think deeply about, because making simple changes, we want the simple solution. But we can't look at this ahistorically, as you were mentioning at many points so far in our interview.

Krieger: But at the same time, change can happen quickly. So, for example, in other research that I've done, the passage of the abolition of Jim Crow led to very marked reductions very quickly in infant mortality. Part of it was [audio drops] the population, particularly in the South. Part of it was that there was an accumulation, pent up demand, because with part of the abolition of Jim Crow, there was the desegregation of hospitals.

Kao: Right.

Krieger: And that was accomplished incredibly quickly. People forget that. That was the Hill-Burton Act.

Kao: Yeah.

Krieger: And basically, what happened was very big carrot with very big stick: you don't desegregate, you don't get federal funds. And in a space of time that was just, I think, 20-odd months, these hospitals, which had sworn, of course, always to maintain the two entrances and the two types of service and all the rest and flat out discriminate and segregate, suddenly had to accommodate. And guess what? They did. So, change can happen quickly, for good and for bad.
