Regarding the Truth

From The Art of FictionParis Review – Summer 2017

Taken from an interview with Ali Smith.


"We are living in a time when lies are sanctioned. We have always lived in that time, but now lies are publicly, rhetorically sanctioned. And something tribal has happened, which means nobody gives a shit whether somebody’s lying or not because he’s on my side or she’s on my side. In the end, will truth matter? Of course truth will matter. Truth isn’t relative. But there’s going to be a great sacrifice on the way to getting truth to matter to us again, to find out why it does, and God knows what shape that sacrifice will take."

Snow Hounds – A Dog’s Tail

Snow Hounds – A Dog’s Tail

 By Ellie 

It had snowed for one-hundred days straight in Sweden. There was no longer any place to put it. The smaller towns were buried first, then cities. Stockholm simply disappeared. Survivors lived below, in tunnels—like rabbits.

Ellie always woke up first these sunless mornings. “Woof.” She nudged her cousin, Mio, who was already awake and wondering where it would all end. “We’re getting out of here,” she growled.

Meo saw she was serious and ready or anything. But . . . there was risk. “You mean we’re going up? On top?”

“The surface.” Ellie stretched. “It’s time to go. It’s now or never. We have to try, or die here in this winter wasteland that’s forgotten summer and remembers only rain, and wind . . . and snow.”

“Tell me about it.” Mio sniffed. “Go where?” “I don’t know. Someplace warmer, where a dog can see the sun. Alaska maybe, or Siberia. Siberia is good this time of year.” “I used to know a bitch from Russia.” Mio wagged his tail. “Whatever.” Ellie trotted off. “We’re going up, then heading north.”

*     *     *
 It took a day from them to dig their way up to the top. The sun was blinding. For a moment Ellie though she felt a bit of warmth, but then it passed, for they were still in Sweden. The brave hounds started off across the endless drifts of glaring white that reflected a sick sun circling a desolate Swedish horizon. They left with only the coats on their backs, and dog-like determination.

Size Matters

Size Matters

The late statistics wizard Hans Rosling, who died in February of 2017 at age 68,  brought at least 10 toilet paper rolls to some of his beloved presentations.  He would stack them into a tower on a table, each roll representing one billion people. In a 2012 talk at the Skoll World Forum, he used the rolls to show how, as the number of children in the world—2 billion—holds steady, the global population will rise from 7 billion to the (also indefinitely stable) figure of about 10 billion. “We are debating peak oil,” he remarked, “but we know that we have reached peak child.”

With his whimsical props and other colorful visualizations, Rosling was renowned as a translator between large, almost unfathomable numbers and the language of everyday experience. He understood that most of us need visualizations or analogies to mentally work with millions, billions, and other big powers of 10 that help define our world. They’re important for decisions that affect daily life, such as how money gets invested and which government policies you support. But just how well—or poorly—do people understand quantities in powers of 10? And how can we better equip ourselves to navigate them?

In thinking about these questions, I started reading about a niche branch of science called numerical cognition. Researchers in this field study not just how we think, but how we think about, and with, numbers.
Not a lot of research has been done on how our minds perceive and comprehend large orders of magnitude—big differences between the size of, say, a cell and our sun. But one academic outwardly passionate about it is David Landy, assistant professor of psychological and brain sciences at Indiana University in Bloomington. Landy has done several studies on how well people understand very large numbers—namely, the millions, billions, and trillions—in relation to each other on a number line.
“To me, the impressive thing is that people succeed at all.”
Short answer: About half the people he studied were pretty bad with handling big numbers. In a 2013 study, for example, Landy and colleagues did two experiments that involved estimating large numbers. The sample sizes weren’t huge, so there’s some uncertainty about generalizing the results, but they’re a start. They found that about half of participants did pretty well in locating numbers on a line in relation to 1 million, 1 billion, etc. But about 35 percent of people in the study used what the authors call a “segmented linear heuristic.” That means they correctly distinguish between numbers within the millions or billions, but assume that “million,” “billion,” and “trillion” are equally spaced on a number line. They were generally great at comparing the relative sizes of numbers like 2 million and 800 million, but many treated 980 million and 2 billion as nearly identical.
In other words, as long as you’re comparing numbers with the same “label” or unit of magnitude—“million” to “million”—you’re quite likely to do fine in estimating relative magnitude. But things fall apart for many in comparing big numbers with different labels—“million” to “billion.” Writing out one with six or nine zeroes doesn’t help any more than saying “million” or “billion,” either, Landy’s research has found. As for powers-of-10 notation like 106, it can lead to even more confusion, according to his unpublished work.

Of course, our ancient human ancestors didn’t live among billions of people, or incur trillions of dollars of debt. The orders of magnitude in their immediate surroundings were limited to what they could experience firsthand. It’s not surprising that we can intuitively visualize a 6-inch or 6-mile distance, but 93 million miles to the sun seems…super far. So Landy sympathizes with people who don’t get all of the number line questions right. “To me, the impressive thing is that people succeed at all,” he said.
“I probably have a better sense of what a solar mass (1033 grams) is than say an ounce!”
That success is important because, as Landy’s studies have also found, making errors of judgment about large numbers can have a big impact on the way you view policies and government decisions. The rationale goes like this: The National Science Foundation received $7.463 billion for fiscal year 2016 through the Consolidated Appropriations Act. The total United States budget outlay for 2016 was $3.54 trillion. If you’re someone who perceives the difference between a billion and a trillion as relatively small, you’d think the US is spending a lot of money on the National Science Foundation—in fact, depending on your politics, you might applaud the federal government’s investment or even think it wasteful. But, if you understand that a billion is a thousand times less than a trillion, you can calculate that the Foundation got a paltry 0.2 percent of the budget outlay last year. (It may be more straightforward to think of the budget as roughly one-half to one-third of reported costs for the proposed US-Mexico border wall, and let your values guide you from there.)
So how can we make large numbers more easily graspable? A group at Microsoft is working on it.
Dan Goldstein, principal researcher, and Jake Hofman, senior researcher, have been running experiments to see what kinds of contextual clues—what they call “perspectives”—help people grasp the meaning of large quantities like distances, dollar amounts, population sizes, and more. In a 2016 study, Goldstein and Hofman, along with Pablo Barrio, a computer scientist at Columbia University, crowdsourced suggestions for perspectives related to quotes taken from the New York Times, and then had participants rank their helpfulness. For a Times excerpt relating to firearms that stated, “Americans own almost 300 million firearms,” the top-rated suggestion was: “To put this into perspective, 300 million firearms is about 1 firearm for every person in the United States.”
1 million seconds is nearly 12 days, whereas 1 billion seconds is almost 32 years.
“We found that perspectives were pretty helpful in helping people recall unfamiliar numbers that they had read, in estimating numbers that they hadn’t seen before, and also in detecting errors in potentially manipulated numbers,” Hofman said. A second study, not yet published, suggests that perspectives can have positive effects on the comprehension of numbers even six weeks after initial exposure, the researchers said.

When scientists navigate their way through extreme numbers in their daily work, they aren’t constantly comparing enormous or miniscule measurements to units of everyday life. Instead, their fields have their own perspectives relative to different units. Priyamvada Natarajan, professor of astronomy and physics at Yale University, for example, said she operates in a totally different frame of reference when thinking about large distances and masses. A non-specialist might calculate that a black hole with a mass 1 million times that of the sun would be on the inconceivable order of 1036 kilograms. But for Natarajan, who routinely deals with these objects, a 1-million solar mass black hole is a unit unto itself. In fact, “I probably have a better sense of what a solar mass (1033 grams) is than say an ounce!” she wrote in an email. “It’s really a question of getting comfortable with these large numbers by really thinking of them relative to each other, not relative to units that we are more familiar with,” she wrote. Jeff Karp, associate professor of medicine at Brigham and Women’s Hospital in Cambridge, Massachusetts, does research at the nanoscale—billionths of meters, smaller than the width of a human hair. It’s a bit like being immersed in a new language, he said. “The more you submerse yourself into thinking about things at the extreme size scale, and start doing these comparisons, and start talking to others, and start reading—the more comfortable you become,” he said.

Some insights that Goldstein and Hofman have gleaned from their research have made their way into Microsoft’s Bing search engine. For example, if you type in “area of” and then the name of a country, you are likely to get a number in square miles with a comparison to a US state underneath. Texas and California are two of the states that research participants had a good feel for in terms of area, Hofman and Goldstein said. So it should be instructive to read on Bing that Afghanistan is about the size of Texas and that Zimbabwe is about the size of California. Some perspectives may need more work. Bing says Argentina is “about 10 times the size of Nevada,” a state with an area that may be less familiar than California’s. “At a low level, almost any illustrative example helps,” Goldstein said. “You can get very precise if you want to really come up with accurate ones that are friendly on the mind.”

Cornell University mathematician Steven Strogatz, for instance, asked people if they had a way to intuitively grasp the size difference between 1 million and 1 billion—and they didn’t. He didn’t find that surprising. In his New York Times article “Visualizing Vastness,” he writes, “Things that are so far removed from our daily experience—like quarks, and dinosaurs, and Kim Kardashian—are inherently hard to understand,” extreme numbers included. But when he linked these numbers to time, it brought things in perspective: 1 million seconds is nearly 12 days, whereas 1 billion seconds is almost 32 years. “Everybody gets it when you say it like that,” he wrote in an email. “If you just said 1 billion is three orders of magnitude greater than 1 million, I don’t think it would make the same impression.”

We live among vast orders of magnitude, but they don’t have to be off-putting. Rosling left an audience, in the 2013 documentary Don’t Panic, with this message: “Look at the data. Look at the facts about the world, and you will see where we are today, and how we can move forward with all these billions on our wonderful planet.”

Remarks delivered at the World Economic Forum
Davos, Switzerland
January 25, 2018

Excerpt From:
The current moment in history 

Good evening. It has become something of an annual Davos tradition for me to give an overview of the current state of the world. I was planning half an hour for my remarks and half an hour for questions, but my speech has turned out to be closer to an hour. I attribute this to the severity of the problems confronting us.
I find the current moment in history rather painful. Open societies are in crisis, and various forms of dictatorships and mafia states, exemplified by Putin’s Russia, are on the rise. In the United States, President Trump would like to establish a mafia state but he can’t, because the Constitution, other institutions, and a vibrant civil society won’t allow it.
Whether we like it or not, my foundations, most of our grantees and myself personally are fighting an uphill battle, protecting the democratic achievements of the past. My foundations used to focus on the so-called developing world, but now that the open society is also endangered in the United States and Europe, we are spending more than half our budget closer to home because what is happening here is having a negative impact on the whole world.

But protecting the democratic achievements of the past is not enough; we must also safeguard the values of open society so that they will better withstand future onslaughts. Open society will always have its enemies, and each generation has to reaffirm its commitment to open society for it to survive.
The best defense is a principled counterattack. The enemies of open society feel victorious and this induces them to push their repressive efforts too far, this generates resentment and offers opportunities to push back. That is what is happening in places like Hungary today.
I used to define the goals of my foundations as “defending open societies from their enemies, making governments accountable and fostering a critical mode of thinking”. But the situation has deteriorated. Not only the survival of open society, but the survival of our entire civilization is at stake. The rise of leaders such as Kim Jong-Un in North Korea and Donald Trump in the US have much to do with this. Both seem willing to risk a nuclear war in order to keep themselves in power. But the root cause goes even deeper.
Mankind’s ability to harness the forces of nature, both for constructive and destructive purposes, continues to grow while our ability to govern ourselves properly fluctuates, and it is now at a low ebb.

The threat of nuclear war is so horrendous that we are inclined to ignore it. But it is real. Indeed, the United States is set on a course toward nuclear war by refusing to accept that North Korea has become a nuclear power. This creates a strong incentive for North Korea to develop its nuclear capacity with all possible speed, which in turn may induce the United States to use its nuclear superiority preemptively; in effect to start a nuclear war in order to prevent nuclear war – an obviously self-contradictory strategy.
