Year in Review: Top Posts of 2017

Looking through the 5 most frequently read essays of 2017, I see few themes. They are mostly attempts to find reasons to be hopeful (even though that has been hard at times). Humans are adaptable and flexible, and we aren’t fated to any single behavioral way of being. That means we can always make a better world. Light up the darkness.


1. The Conditions of the Game: It’s Not a “World of Eternal Struggle” (Sept 2)

This was by far the most read post on this site, which I wrote after the violent clashes in Charlottesville, Virginia. This was upon seeing a photo of a man with a t-shirt that quoted Hitler in which he wrote that ours is “a world of eternal struggle.” I found it disturbing, but also just wrong. In evolution, adaptations are context specific, and they depend on the conditions of the game. This is also true for cooperation and conflict.

“How we view the world matters. If we see it as zero-sum, as an eternal struggle against other people where only one party can win, then we will act accordingly. Norton and Sommers (2011) found that many white people see racial relations as a zero-sum game: that if other groups are making progress toward equality, that this progress comes at their expense. But remember that non-zero-sum relationships are widespread. With cooperation so prolific in nature (genes, cells, organisms, groups, human societies), it just seems odd to declare that life is solely a contest of struggle. Nor does it make sense to say that cooperation is impossible between groups. Or we can see it as a chance for coalitions, that the success and well-being of others around us does not require us to lose. We make a niche for the others around us, as they do for us, and we all decide whether the costs that come with building up our armor are worth it. They may be, depending on how we perceive the conditions of the game.

I don’t know about you, but I think my life would be better if I was surrounded by healthy, fulfilled, cooperative people over those who feel distrustful, held back, and resentful. Of course, some people may feel differently. There are many strategies one can use. But don’t argue that nature gave us only one hand to play.”

On Multiraciality: Perceptions of Homogeneity and Difference

“I note the obvious differences between each sort and type./ But we are more alike, my friends, than we are unalike.”  (Maya Angelou, Human Family)


It’s been said that young primates engage in social learning in three main ways (van Schaik 2016). They can obtain information horizontally (from peers), vertically (from parents), and obliquely (from other adults). For the most part, the vertical transmission of information tends to flow in one direction; juveniles learn from the experiences of their parents rather than vice versa.

Yet parents can also learn from their kids. The street is not entirely one-way. My own children (who are also primates, just like you and I) have taught me a lot: from what they learn in school, see online, or their slang (derp). As “biracial” children, they’ve also taught me a few things simply by existing. There are general lessons that most parents learn – that having children can reorient priorities, and that parenting is a mix of vicarious pain, joy, and fear. For me, one specific lesson as a specific parent of these specific children, has to do with the ways that people perceive similarities and differences. I’ve been hesitant to write about my kids here (we all deserve some privacy). Still, I think there are some lessons I’ve learned that might be useful.

First, a step back. Most of my recent ancestors, as far as I know, come from Ireland and Britain, with some Scandinavians thrown in there, as well as ancestors from other regions of Europe. Oh, and Neanderthals too; they aren’t exactly recent, but we can’t forget them. Before that, my ancestors eventually trace back to Africa, as is true of everyone. If someone were to ask me about my ethnicity, I’d probably say that I am Irish-American, though I know that any label must necessarily discard some complexity. After all, a single name cannot possible encompass the nearly infinite number of  ancestors standing behind me. Identity, ancestry, and genes certainly correlate with each other, but never perfectly so. My wife is the daughter of Korean immigrants and would refer to herself as Korean-American. And her recent family tree, as far as she knows, contains ancestors who lived not only in Korea, but also in northern China.

How Our Lives Intersect

Below is one artist’s (Nancy Belmont) illustration of the many ways our lives intersect. In the video, she cleverly gave people yarn which they wrapped around a series of poles representing a number of possible groups to which someone might belong.

When the experiment is complete, we see the full picture and the various ways the participants’ lives overlap and the commonalities people share.
