Of Trolleys and Mice

The trolley problem is one of the most famous thought experiments in ethics. You are asked to imagine that there’s a runaway trolley racing down the line. It’s headed toward a group of five people who are tied to the tracks with no prospect of escape. From your vantage point in the trolly yard you have access to a lever that can divert the trolley onto another set of tracks, on which a single person is tied. The question is, would you pull the lever? Numerous surveys have found that about 90% of people would do so.

In a variant of the trolly problem, you’re on a bridge watching the trolley barrel down toward those five tied-up people. Standing next to you is a man. You know that if you push him off the bridge, his bulk will stop the trolley, saving the people bound to the tracks. Not surprisingly, even though the outcome is identical to the first instance–sacrificing one life to save five others–far fewer people would push the man off the bridge.

We’ve got mice in our garage. Lots of them. They gnaw into bags of stored food, poop everywhere, and for all I know promiscuously spread hantavirus. They’ve got to go. But the idea of poisoning them, or even setting up kill traps, is abhorrent to me—they’re simply cute, furry innocents doing what mice are supposed to do. So, I’m using a “live trap.” The critters are lured by peanut butter into a little plastic cage, which captures them without harm. Each morning I check the trap. If a mouse has been caught, I drive it to a nearby forest and release it beside a decaying tree stump. Most often, little Mickey frisks out of the trap, sniffs the air right and left, then rushes right into a hole in the base of the stump. I’ve been very pleased with myself for this arrangement.

For confirmation that I was doing the right thing, I Googled ‘the most humane way to rid your house of mice’. I was startled to read that, overwhelmingly, the advice from animal advocacy groups is that quick and certain death with an old-fashioned snap trap was the way to go. How could that be? Well, it turns out that the kind of mice that end up infesting houses don’t do well in the wild, especially when transplanted far from where they were trapped. They can’t adapt to the new environment and perish due to starvation, disease, or predation. Yikes!

Even so, after reading this thoughtful advice I’ve persisted in “humanely” trapping the mice and transporting them to what is apparently certain sylvan death. In other words, I’ve continued to pull the lever rather than push the man off the bridge, thus distancing myself from directly causing their demise. Even worse, as opposed to the trolley problem, where the two modes of death are equally sudden, it appears that out of cowardice I’m opting for the more inhumane mode of exit.

Well, of course, the rationalizations came flooding in: Maybe the forest wasn’t all that far from our house, or maybe these particular woods harbored plenty of rodent-friendly food and water. Maybe the previous releasees had been able to set up house in the hole in the stump, so the new arrivals would be welcomed into a thriving colony of their former housemates. Maybe these environs weren’t rife with rodential predators. But on the other hand, if there were predators, and the mouse was going to die anyway, wouldn’t it be better that it served as nourishment for the resident eagles and foxes and owls rather than being thrown in the trash after getting whacked by a snap trap? Finally, in any case, even if the released mice had only a slim chance of living a full woodsy life, wouldn’t that be a better alternative than certain death in our garage?

And yet… All the organizations associated with animal welfare were clear: they strongly advocate a quick and painless death as the most humane alternative–my rationalizations were fooling only me. But, I must admit, I still haven’t changed my practice. The fact is, it’s so much easier to pull a lever than to push someone off a bridge. So, so sorry, my little furry friends.

Purebred Mongrel

My recent 23andMe report tells me that I’m 96.8% Ashkenazi, that is, Eastern European Jewish. This was quite disappointing. I always thought I was—and aspired to be—some sort of exotic mongrel; I’ve long been a proponent of the virtues of hybrid vigor. But it looks like I’m actually a purebred. Well, almost. What about the remaining 3.2%, the tiny chromosomal fragments that aren’t of the breed?

Turns out that they aren’t particularly interesting: 0.9% Eastern European, 0.4% Southern European, 0.2% Iberian, 0.1% Northwestern European, and—finally something a little off the beaten tribal path—0.1% Scandinavian! How nice to know that I’m at least a slightly mixed breed. But though I’m part-Scandinavian, I have to admit it’s a tiny part: if I were to convert the 0.1% of genes into 0.1% of my body weight, I’d be about 2 ½ ounces Scandinavian. That’s less than the weight of a serving of pickled herring.

If you add up these tiny bits of identified non-Ashkenazic genes, you get 1.7%. So what about the remaining 1.5%, which is unaccounted for by 23andMe? Maybe it’s just a rounding error. Or maybe it’s the most interesting part of my genetic heritage, which will remain captive until I pay the company a ransom for its release. It could still be that I’m more exotic than it appears.

In any case, I presume that those non-Ashkenazic European gene fragments represent interlopers who slipped into my purebred lineage long ago. In fact, 23andMe specifically informs me that the 0.1% of Scandinavian genes in my possession “were contributed by a single ancestor who was 100% Scandinavian, born between 1680 and 1770.” I wonder how they know—did they find a diary? However they determined it, it seems that this 98.6% pure Ashkenazi apparently had a great-great-great-great Grandpa Thor. I suspect that Grandpa Thor was a Viking warrior King, I can sort of feel it in my blood.

Uff Da! (whatever that means)—now I know why I’ve always enjoyed taking saunas! And maybe now that I’m aware of my Scandinavian heritage, I’ll start to think that Garrison Keeler’s Norwegian bachelor farmer jokes are actually funny. Moreover, since I’m surely eligible, I think I’ll put in an application to join the Sons of Norway. Conveniently, the nearest chapter is in Poulsbo, just a few miles from where I live. Maybe I’ll even run for office in the next SoN election—the prospect of an Ashkenazic-Norwegian treasurer might be a real vote-getter. At some point, I should sign up for one of those “roots tours” to the Nordic countries to see if I can connect with my heritage, and maybe track down a landsman or two. I’m even thinking of giving lutefisk another try. How wonderfully life-changing it is to learn of this 0.1% of my gene pool!

Parental Passions

My parents’ passions were pretty much all in their heads. My father’s life was science. Making new discoveries and getting them published was his highest aspiration. Based on the time he spent with each, it seemed clear to me that he loved his lab more than his family. As for my mother, she wanted to “have it all” decades before that became a term. Having children was part of it, but mothering seemed less important than the work part of “all”. She ran a social work agency. She was president of the local Hadassah chapter. She was a university professor. As I was growing up, she got a PhD. In fact, my recollection is that she nurtured her thesis more than she nurtured her sons. When I was ten she required me to help her proofread her dissertation, a long and agonizing undertaking. My reward was a complicated game called Brainiac that never seemed to work right, and that I never enjoyed.

Such cerebral passions were hard for a kid, even a nerdy one like me, to accept. But I vividly remember two instances of physical passions, each of which made a deep impression because they seemed so out of character. One time, armed with plastic pails, we were all gathering blackberries. The pails quickly filled with shiny, jewel-like fruit. Except for my father’s. Why not? He put virtually every berry he picked into his mouth. Soon his hands were stained purple, as was his white shirt (he almost always wore white shirts). He had a goofy grin and vocalized crudely—mostly “umm, umm, umm!” I found his visual and audible display of blackberry passion more upsetting than endearing.

My mother’s physical passion also involved eating. She loved corn on the cob. She would slather it with butter, then shake pepper over it until it nearly turned black; the corn looked like it was crawling with ants. But what impressed–and disturbed–me most was not the peppery excess, but the intensity with which she applied it, and the lust with which she consumed the corn.

Although it didn’t increase my sense of being nurtured, seeing my parents experience such pleasure from food reassured me that they were at least somewhat normal. But at the same time these behaviors seemed undignified and embarrassing, in fact almost carnal. My reaction recalled the time, while rummaging through the top shelf in my parents’ bedroom closet (they were, of course, both at work), I discovered a big red box of Trojans. Yikes, my parents actually did it! How unexpected, and how gross!

My childish feelings toward my parents are an example of how we tend to reduce people to a few salient features. In other words, we make them into cartoons. This can be useful since it gives us a handle on who they are. But it’s way too simple: though my parents were indeed in their heads much of the time, they were more complicated than that. Their heads were connected to their bodies. And these bodies were passionate about certain foods, almost certainly enjoyed other sensory experiences, and yes, even made love.

If we can avoid reductionistic views of people, we can more fully appreciate them in all their contradictions and complexity. I aim to try to do so in all my relationships. Enjoy those berries, dad, and have another ear of corn, mom!

Looking but Not Seeing

We decided to hang a beautiful quilt on the wall of our grandson’s bedroom. I began by sewing a flat wooden stick across the top of the quilt so it would hold its shape. Then I needed two screw eyes to put at each end of the stick to hang it. So I went out to the garage and started rummaging through my trusty parts bin—it’s a little metal box containing 24 plastic drawers. It’s totally unorganized: in a single compartment you might find carpet tacks, washers, brass nails, a curl of wire, you name it.

Random rummaging didn’t produce any screw eyes. Thus, I started systematically at the upper left-hand drawer and worked my way across, then repeated the process across the next row. And eureka! At about drawer # 17 I indeed found two screw eyes snuggling up against some yellow wire nuts. I returned to the bedroom and attached them to each end of the stick. But then I needed two nails to hammer into the wall, on which to attach the screw eyes. What did I do? Naturally, I went back to the parts bin. Hmm. It occurred to me that just a few minutes previously I’d gone through almost all the drawers—why didn’t I remember which drawer contained the right size nails? The answer was obvious: I wasn’t looking for nails; I was looking for screw eyes. So I had to go through the whole drill again—across and down, across and down, looking afresh for nails. After digging through all 24 drawers, I decided that the nails in drawer # 8 would work the best. I was then able to hang the quilt. It looked quite nice, thank you very much.

After admiring the new wall hanging, I remembered that I’d decided to put a blackout curtain over the window so Ari would sleep better during his nap. To do so I needed push pins. Where could I find some? In the parts bin, of course. Did I recall seeing any push pins from the previous two romps though the 24 drawers? Of course not—I hadn’t been looking for push pins. So once again I started with drawer # 1.

What does this tell us about how our minds work? Among other things, it shows that we simply can’t take in the incredible amount of information that surrounds us, clamoring for our attention–we need to focus. But focus also means exclusion: the more we focus, the less we see. Thus, perhaps, the more single-mindedly we pursue a goal, the more we miss in life.

In a famous experiment, experienced radiologists were given a series of chest x-ray images and asked to identify any lung cancers. On this task they did very well. However, on one of the images the researchers superimposed a rather large black silhouette of a man dressed in a gorilla suit. And guess what? Only 18% of the radiologists noticed it! It’s not surprising that the vast majority didn’t see the hulking image—they were looking for cancers, not gorillas. This phenomenon is awkwardly but descriptively called “inattentional blindness.” In other words, “hiding in plain sight.”

No matter how busy we are, I think it might be a good idea to spend part of each day focused on nothing. Who knows what we’ll see!

Particles of Smoke

As I write this, our island, and much of the west coast, is being heavily infused with smoke. It’s coming from massive wildfires in California and Oregon, blown north by the prevailing winds.

It’s high noon, and everything is a dreary brown. The world looks like one of those old sepia prints with all the joy and life sucked out. Our windows are closed tight, and the air purifier is striving mightily to collect all the smoke particles that have managed to burrow their way into the house.

While out walking the dog with my N95 strapped on, I marvel at how dense and pervasive the smoke is. It must take gazillions of tiny products of combustion to block so much of the sunlight and foul the air. I think about how each of these smoke particles made the epic journey north. For example, as it crashed to the charred ground, an immolated Douglas fir deep in the Klamath National Forest in northern California sloughed off a chip of ash from a high branch. It was then carried aloft by a swirl of hot air, rose higher and higher, and spun out individual particles.

I imagine tracing one of those smoke particles on a 3-D map: Up, down, spinning around, going out to sea, then being pushed back to land as it travelled as part of an enormous pulsing pack. It back-tracked, zigged and zagged, then slowly lost altitude over Bainbridge Island. Drifting downward, it daintily settled on the visor of my hat. Then, right next to that minute fragment of the Doug fir may have settled a particle of smoke originating from the roof joist of a barn near Clackamas, Oregon.

After hundreds of miles of mixing, it’s clear that the pall of particles blocking the sunlight is actually a motley collection of bits thrown together from the residual of burned trees, buildings, animals, and grass from dozens of fires hundreds of miles apart. Thus, this smoke is a profound reordering of the pre-fire relationship of matter from forests and towns all over the northwest.

But then, I think, this massive mixing of matter isn’t confined to cataclysmic events; it happens all the time. For example, though I think of my body as a single unit, it’s made up of a vast number of widely sourced components. Consider the keratin forming the tip of the leftmost eyelash of my left eye. One of the carbon atoms making up part of that polypeptide chain may have come from the Bocca Burger that had for lunch with chipotle mayonnaise and a pickle a few weeks ago. And another part of that chain might have been derived from a bit of an epithelial cell from my tonsil that sloughed off, was swallowed, re-digested and reabsorbed by my small intestine. And for all I know, even before it was part of my tonsil it came from the crust of the fabulous pizza I had at Roberta’s in Brooklyn before covid, when it was still possible to eat out.

And so on, for the entire complex assemblage of my physical body—the noodle soup we ate after our arrival in Shanghai, a drop of sea water that landed on my upper lip as I paddled my kayak in our little cove, the awful bagel we had at that restaurant in Victoria, the mustard greens from the stir fry made entirely from the bounty of our garden last summer. Such diverse sources of matter are incorporated into my vagus nerve, and my right atrium, and the lining of my pancreatic duct.

So, like the huge mass of smoke swirling around me now, we’re all composed of ever-changing material from disparate sources, temporarily joined together. But as Carl Sagan famously said, the ultimate origin of all the shifting components of the smoke, of me, and of everything on earth unites everything together again: “We’re made of star stuff.”

Dancing under a mushroom cloud

One evening in late October 1962, my father was driving me to a ballroom dancing lesson. I was an awkward 14-year-old, very shy, and a horrible dancer to boot. I dreaded these lessons. Foxtrot was the least painful for me since it was pretty easy to slur my steps and keep from hitting my partner’s shoes. And waltz wasn’t too bad since most of the time I could actually hear the ONE-two-three, ONE-two-three beat, and launch my feet in sweeping Ls accordingly. Cha-cha was way too intricate, and tango was simply out of the question.

We were in our tiny Fiat 600, well before the days of seatbelts and air bags. The radio was on high volume, competing for audibility with the various rattles of the car. The news announcer was reporting on the increasingly tense showdown between Kennedy and Khrushchev over the Russian missiles in Cuba. The US had set up a blockade to intercept all ships heading toward Cuba. The Russians said they would ignore the blockade, and threatened war. A showdown seemed imminent. My father was completely silent, eyes fixed on the road ahead. When we arrived, I said goodbye with uncharacteristic emotion. I thought I might never see him again.

The dance lessons were conducted in the basement of the house of a matronly woman whose name I forgot half a century ago. The floor was dark linoleum, and I think the walls were cinderblock painted white. Other than the staircase that went down from ground level, the only connection to the outside world was a narrow, horizontal rectangular window high up on the wall. The music came from a little record player sitting on a cabinet.

The class consisted of about 6 boys and 6 girls, some nearly as nerdy as me. The instructor paired us off into uncomfortable couples, and we waited for the scratchy record to begin. I was horribly self-conscious on the best nights, and this wasn’t one of the best. It was hard to concentrate, even on the Foxtrot. I kept glancing up at the rectangular window, expecting at any moment to see a bright orange flash.

In school we’d been regularly drilled in what to do when the air raid alarm sounded. If we were in a classroom we were to dive under our little desks and curl up in a protective ball, hands over the backs of our necks, eyes closed. If we happened to be changing classes, we were supposed to drop where we were and lie prone on the floor, our heads against the base of the lockers and our feet sticking out into the hallway. Since the dance studio had neither desks nor lockers, I had no idea what I was supposed to do when we heard the sirens.

Somehow the molasses-infused time passed, no sirens rose above the music, nothing flashed, and the lesson was over. We all emerged from the potential basement tomb and silently dispersed to the cars of our waiting parents. I don’t remember the radio being on on the drive home—perhaps the crisis was over. Or maybe it had become even worse. Ultimately, of course, Khrushchev backed down, the missiles left Cuba and we were once again safe from imminent annihilation. But somehow, ever since, I’ve never enjoyed dancing.

Sealy

When we look out onto the little cove in front of our house, we often see a harbor seal. With its head poking out of the water it carves a little wake as it swims around our dock. We call “him” “Sealy.” Sealy is usually by himself, and we worry that he might be lonely. But occasionally he has a companion, which makes us happy. Sometimes Sealy follows our kayaks when we’re out paddling—he shows off by corkscrewing underneath the boat and coming up the other side, surfacing and staring at us with his liquid brown eyes, while gravely flicking his whiskers and softly snorting. But even from that close, Sealy always looks the same—like a seal. Suddenly, several years ago it occurred to me that maybe all the sightings weren’t of a single seal, but of a whole multitude of them—Sealys 1 through 20, say. How can you tell one seal from another, since they all look the same?

Between my third and last years of medical school, I went to Northern Thailand to do medical research. Back then there were very few westerners in that part of the country. After about six months I realized that on casual glance I could often tell whether a person I encountered in the hospital or the market was an ethnic Thai, from one of the various hill tribes, or an ethnic Chinese, who commonly lived in Thailand. Not by any special effort, but just automatically. Unexpected, however, was that as the Asians I was living among began to look quite distinct, I became unable to distinguish among the western tourists who occasionally came through our town. At the night market, where we often went for dinner, we’d sometimes hear English or German or French spoken at a nearby table. I’d look up, and see some white people–they all had the same pale, reddish skin, bulging eyes, and big noses. They all looked vaguely familiar: I kept thinking that I knew them, but wasn’t sure exactly who they were. It was unsettling. I was much more comfortable looking at the Thais at the other tables.

Occasionally, we’d travel to a remote village to follow up on a patient we’d cared for in our hospital. There was a lot of medical equipment to carry, and the paths up into the mountains were too narrow and twisty for any vehicle. So we’d bring along elephants to schlep the loads. Occasionally on the way up we’d encounter a Kariang hill tribe family on the way down; they would have to climb up the slope next to the path to make way for the elephant brigade. Then, after the elephants passed they would come back down, wave, and say the equivalent of “hi!” to the Thais in our group. But when they saw me, they’d start laughing and pointing and talking quickly to each other. Then a bold one, usually a child, would approach me and stroke my moustache or carefully trace the skin of my arm with their fingers. I don’t think it occurred to them to look me in the eye, or even to talk to me; they rightly figured there was no way I could understand them, or they me. I wasn’t an individual, but rather a random member of an exotic species—an undifferentiated white man. I was the human equivalent of Sealy. Though the Kariang examined and stroked me in good humor and completely without malice, it was still unsettling.

Having had a more attenuated but similar reaction to white people in the night market, I could understand the Kariang’s reaction much better than if I’d never had that experience. And I more deeply understand how easy it is to “other” groups of people we aren’t familiar with. “Sealy” is now simply “a seal.”
