Thresholds of Inclusion

“Madam, do I not destroy my enemies when I make them my friends?” (Abraham Lincoln)

 “Blood just looks the same, when you open the veins.” (Karl WallingerIs it like today?)


If you wish to find someone just like you, who looks and thinks exactly the way you do, then perhaps the only place you can look is in a mirror.

However, here’s a thought. Imagine that as you’re looking at the mirror it begins to move progressively farther away from you. The further away it is, the more time that transpires before the light bearing your image reaches the mirror and returns. If, in this scenario, the mirror should reach, say, the distance of the sun (for the sake of argument, it’s a really big mirror), then the image that you would see is still yourself, only it’s you roughly sixteen minutes ago.

And, if you have somehow changed your mind about something, or started to feel hungry or tired, or for whatever reason altered your mood within the last sixteen minutes, then the person in that reflection and the person you are now do not exactly see eye-to-eye on everything. In that time, you’ve aged a tiny bit, lost some atoms and gained some new ones. Technically, that mirror image doesn’t represent the ‘you’ that you’ve become quite as accurately as it once did.  

The point is that if we take this thought experiment to its limits, it becomes apparent that we will never find someone who is perfectly like us – not even you, eventually. Still, we manage to care a great deal about our ever fluctuating selves. We also care about others who are at least somewhat like us, and even (sometimes) others who are not so like us. The question is where we draw the line and about whom we should empathize. Of course, that line is negotiable and circumstantial, and we all have our own thresholds of inclusion.


Moral Circles

moral circles

Moral circles

In his book “Primates and Philosophers,” Frans de Waal described the evolution of morality, including the idea of expanding “moral circles.” Our ancestors would have found it easier to care primarily about the people closest to them, but they could also spread out from there – ourselves, then family, their village, ethnic group, humanity, etc. The circles are not permanent, but can be expanded or retracted depending upon circumstances.

This makes sense. It is not possible to love or feel empathy toward all people equally, at all times. This is not to say that we cannot comprehend treating all people equally in an abstract or legal sense. However, our attention and mental capacities are finite, and we must choose our favorite people and give preference to certain relationships, at least at any given moment. I have my favorites, you have yours, and in all likelihood they probably do not align. However, when times are good, it becomes easier to add more people to our circle, even if only temporarily, and even if they differ markedly from us. When times are tough, our circles may contract. de Waal put it this way: “the circle of morality reaches out father and farther only if the health and survival of the innermost circles are secure” (2009: 164).


Us and Them

There is evidence that we have a harder time empathizing with someone if they belong to an outgroup. In the screenshot below, David Eagleman ran such an experiment by having volunteers watch the hand of another person being pierced by a needle. According to Eagleman, when we witness another person being hurt our own reaction is usually to activate our brain’s “pain matrix,” indicating that we feel another’s pain. However, when people learn that the hand of the person being stabbed belongs to someone from another religious group than their own, empathy tends to flatten. How does this work?  

Ed Yong described a similar study by Alessio Avenanti where volunteers watched hands being pierced by a needle. In this case, Avenanti recruited black and white Italians. Sadly, empathy was limited to situations when the observer and the person in the video were similar in pigmentation. However, observers showed a strong empathetic response when watching a digitally enhanced video of a violet-colored hand (and thus not belonging to any existing ethnic group) being pierced.

The upshot is that it doesn’t look like empathy is automatically confined to one’s own ethnicity by default. Rather, empathy was impeded by historically constructed racial biases. After all, violet hands do not exist. Yet we can still empathize pretty easily with a person if they come from some neutral category (even if they are violet). However, when we learn that a person comes from a more oppositional outgroup (a ‘them’), then empathy becomes harder to muster. Up to that point, in theory, a human being is a human being.

Here is one example. In 2014, a member of Iraqi parliament, a Yazidi woman named Vian Dakhil, pleaded with her colleagues to help her constituents, who were being killed and brutalized by ISIS. Her speech was widely shared on social media by people who had never even heard of the Yazidi, as they are a relatively small ethno-religious group. Since most people in the world had little prior knowledge of them, they also had no historical grievances to impede empathy, much like Avenanti’s violet-tinged hands. As a result, there was no hesitancy or any “yeah, but the Yazidi have done … XYZ too” moment. She was simply a human being who was hurting, and her pleas touched many people. I still have a hard time listening to her without getting teary-eyed.

A Mental Switch

An interesting question is how that mental switch is flipped, when a ‘them’ outside of our moral circles becomes an ‘us’ (or vice versa). A recent experiment by psychologist Sasha Kimel and colleagues addressed something along these lines (Kimel et al 2016). Kimel gave ethnic Arabs and Jews different versions of fabricated news stories that summarized studies on genetic ancestry. Some versions emphasized genetic similarities and shared ancestry between Arabs and Jews; others emphasized genetic differences. They found that when participants were given versions of the research summaries emphasizing genetic similarities between Arabs and Jews, they later felt less bias and hostility, were more optimistic about the Palestinian-Israeli conflict, and were more open to political compromise. Studies that emphasized genetic differences and distinct lineages generally had the opposite effects, indicating that we can be nudged to see others into a positive or negative light.

Within any species, no population is completely distinct or similar to another. Similarity and difference are a matter of degree, not kind. Kimel et al. addressed this, suggesting that our tendency to think in terms of essentialist categories is likely a key factor in cooperation and conflict:

“Yet, a question that remains is: what is the fundamental process underlying this relationship? We suspect that altering perceived intergroup genetic overlap may be particularly powerful in both exacerbating and mitigating ethnic conflict because it shifts ‘essentialist views’ of these groups or beliefs in their fixed, core nature.” (p. 697)

To some extent, we can’t help but to think categorically. We like putting things into boxes. Robert Sapolsky described part of the process that occurs within our brain – or at least monkeys’ brains – when we are figuring out how to categorize fuzzy objects:

“Our propensity to break continua into categories on a neurobiological level was shown in a beautiful study in which monkeys looked at pictures of a dog or a cat, while the electrical activity of neurons in their frontal cortexes were recorded. There would be neurons that solely responded to dog, others to cat. Then, the scientists morphed the dog and cat together, producing pictures of an 80 percent dog/20 percent cat, a 60 percent dog/40 percent cat, 40/60 and 20/80. Remarkably, neurons responded categorically. For example, a “dog” neuron would respond equally robustly to 100 percent dog and 60 percent dog, and hardly at all to 40 percent dog. In other words, the drive toward categorizing is so strong that in this circumstance, these neurons consider 60 to be closer to 100 than to 40. So we think categorically.”

Thinking categorically is a useful evolutionary strategy in that it helps us make quick assessments and predictions about an object, person, or other species. This is true whether we’re talking about cat or dog, friend or foe, or within our moral circles or not. The alternative is to be frozen by indecision, which is obviously counterproductive. However, our assessments are not always accurate. As  we get new pertinent information our categorizations may shift. If it turns out that what we thought was a 60% dog (i.e., just a dog) exhibits other cat-like traits that we didn’t notice before, then our perception may shift to cat. Similarly, a 55% adversary might become a 55% ally. It might take some mental effort, but the ability to empathize with an ‘other’ is possible when consciousness is raised and hidden commonalities are brought to the forefront.

We cannot always agree with others. You may disagree with me now. After all, you are not me. But I am not always this version of me. And you are not you either, at least not exactly the same you who began reading this essay. Still, the commonalities and places where we overlap with ourselves and with others are always there, if we choose to look for them.

  2. The simple ring structure outward, as presented by Franz de Waal, is of course a simplification. Human beings tend to develop individual networks that can reach out past family members; and they do this from early childhood, making close bonds with friends and forming mentor and peer relationships that reach out well past ethnic and linguistic boundaries. I think this important to remember, especially when looking at concepts of in-and out-group dynamics.

    In the criteria whereby we judge who stays within our individual networks, it is not just established friendships, or even close kinship that is most critical.. rather, common values, quality of judgment in assessing information, and the use of compatible metaphors are also of significance. Within human societies there are conflicts due to such things all the time: imagine how the issue of slavery, of climate change, or taxation, for example have mobilized opposing points of view. Could a creationist escape a certain amount of anguish if he married to an atheist evolutionary biologist?

    However, what this means is that an “out-group” is created by biological distance, and not intrinsic. As history shows, an “out-group”, in fact, can be created that divides families, turns lovers into enemies, severs lifelong friendships, just as easily as it replaces curiosity about newcomers with loathing. In other words, human collective aggression is not about territorial imperatives, it is about social rejection. It is about the fact that protecting a mutuality of cooperation trumps individual advantage. If the first sacred value is finding joy in common humanity (an adaptation via species imprinting and a very ancient) the second is the merger of individual identity with a larger entity, consisting not just of known companions but of all others, even strangers, who share a common cause.

    If there are is anything that sets humans apart from all other animals, it is the scale of our imagination. We do not merely have mental maps and mental time travel to help us navigate the world of our experiences, we can imagine places that never existed, and travel beyond our own lifetime. We can even imagine a supernatural being which sets stars and planets spinning, and a reality beyond time and space. Because of what humans are, we can imagine things and even argue about their relative truth, and the way someone else interprets truth can mean as much to us as whether they are fat or thin, old or young, beautiful or ugly. Sensual impressions are important, but the quality of minds often trumps everything else.

    So intrinsic is this that I wonder if it might also be an adaptation. What other mechanism explains the quality of wisdom that eventually casts a third tier of mental toughness, made up of toleration, and the insistence that no one can ever know everything, over most squabbles? Differences of opinion and interpretation lead to networks based on like-mindedness, and these tend to crosscut ties of kinship within each human community. So, obviously, communities have mechanisms to limit the resultant unraveling.

    Keeping peace between different communities of people often means overcoming impediments of a more profound kind. It means finding common ground, despite linguistic and philosophical differences. The incentive for this is not individual so much as cultural: indeed ultimately animated by the collective political and economic paradigms embodied by the participants.

  4. I imagine it to be helpful to think of empathy as the built-in, free with version, and sure, it can work across the internet and across cultures if we recognize the same circumstances somehow, perhaps intuitively, and sympathy as the directed, directable conscious version, where the sameness perhaps didn’t jump out at you but with an effort, we can go looking for it.
    I’m nurturing another idea, though, that relatedness explains positive things, but that to explain the negative where relatedness is not present or fails, we seem to fall back on some negative idea of human nature, where good things are to be studied and explained, but bad things are not, they are simply to be expected. And I think maybe, the natural prosociality of family and kin is perhaps matched in the human being by some evolved strategy to actively use and abuse the other, that relatedness theory can be seen in the negative, in the inverse, that the less related a person is, the more our response may be to exploit them, to other them – I think this is 50 – 50, right, good and bad in balance, sort of? It sounds bad, like I’m saying exploitation is built-in, and of course, nothing is built-in “hard,” and to acknowledge the bad half rather than to deny it is positive, right, you have to admit you have a problem that’s always the first step. I worry that our society depends upon having that other, and I think that could change, in fact I’m convinced it must change or . . . or this, and the end soon, apparently.
    It’s my latest, blog, more like a small book, that that negative origin story, the idea that we are born bad (or still chimpanzees or something completely backwards from evolution) is a camouflage, a do not look here sign, and that mostly, we obey.

    but cheers, P.!


  5. You know what I mean? Extreme, dysphemistic example – you ask an evolutionary biologist to explain slavery, war, and genocide, and he comes back saying because they’re not your kids or your mom, and it’s because you love your kids and your mom . . . completely dodging the question and getting away with it, because we all share the same shit attitude, original sin or still chimps or something.
    I’m serious.

    sorry to bug.

    • Hi Jeff,
      I know what you mean. Distilling everything down to genetic interests (ultimate explanations) has a lot of limitations in people, who are often after other interests like pride, resources, etc.

      • OK, I’ll try to stop that. Deep down, I know I am working this stuff out for myself and I’m sure that either a handful of modern philosophers are ahead of me on it, or that the entire human race is, but for one reason and another, I need to work it out myself anyway, that it wouldn’t be the same reading it from someone else. I keep hoping someone will tell me who those philosophers are, though, just so I can have more hope, so I can feel like somebody sees it. That last book was such an awful tease, dude pretty much stole my catchphrase and neutered it.
