First, pick an arbitrary point in time. Pick a year, any year A.D. up till your birthday or when you were twelve—this is your year. If you can, conjure up some idealized image of your year in your mind’s eye—nothing terribly analytic for now, just something holistic.
Second, pick a year in time a few years back from your year, and pick a year a few years forward from your year. And, if you would, conjure up the same kind of images for these two years. Again, these need not be exacting—think of them as blurry, semi-liminal collection of facts and themes and truths and so on. You don’t need to memorize all the details of the goat, in other words—just some vague but substantive handle on it.
Third, get ready to perform some mildly unusual comparisons—not impossible, just a little strange, a little odd, but highly interesting, I promise. Try to imagine the difference between your year and the year a few years back. And while you’re at it, try to imagine the difference between your year and the year a few years forward too.
It’s a funny thing to try to imagine differences in the world over time. But that’s why we’re starting with this pretty easy exercise. It’s pretty easy to imagine the differences between things that are pretty similar—whether those things are different kinds of four-legged mammalian farm animals or different states of the world a few years apart.
Still, it may not be obvious to you what the differences are (1) between the world in your year and the world a few years before that or (2) between the world in your year and the world a few years after that. Given that you only care about the holistic view, you might be tempted to conclude that there are no substantive differences looking forward or backward. That’s fine—maybe there aren’t any.
But if there are differences within (1) or within (2), you should then be able to compare those differences themselves. Think of it this way. I grew up in Madison, Wis., which is about two hours from Chicago, Ill. Thus one difference between Madison and Chicago is location, and we can measure that difference in distance quantified by how long the drive is. Madison is about five hours from Minneapolis, Minn. Put this way, it’s natural to compare the differences between Madison-Chicago (two hours) and Madison-Minneapolis (five hours). That difference—that difference between differences—is three hours.
We can do roughly the same thing for your year looking back and your year looking forward. So you might say the difference between your year and the one a few years before is “small.” And you might say the difference between your year and the one a few years after is “small.” If so, the difference between the differences is zero. If the differences are “small” and “medium,” though, difference between the differences might be, e.g., “modest” or also “small.” And so on.
Whew. So the reason all this is important is that the differences between looking back a bit and looking forward bit are usually zero or small. Usually, change is constant. Our intuitions are largely built on this premise. In fact, we get terribly confused and distraught and sometimes incoherent when the difference looking forward is much greater than the difference looking back.
Consider the notion of precedent as legal philosophy. Scholars argue that precedents as reasons make the law more predictable—litigants can better predict the outcomes of law suits if they have some handle on the kind of reasoning judges will bring to bear. But why should law suits be predictable in the first place? That assumption reflects a deeper belief that similarities between previous cases and present or future cases are relevant at all. It reflects a belief that lawyers and judges can emphasize the relevant similar facts and ignore the relevant distinguishing facts. But how should lawyers and judges be able to make value judgments about which similar and distinguishing facts matter across different cases? It can only make sense to conform to precedent inasmuch as it makes sense—on average, I suppose, though even that is tricky given fat-tail risk—to take history as a competent guide to the future. Mere differences in time mean nothing.
But what if something so essential to our ability to reason did mean something? What if mere differences in time mattered legally? Or what if something seemingly arbitrary variable about the world mattered? What if, for example, we thought that events that obtained under a full moon were different from events that obtained under a new moon? We’d have at least two entirely different sets of legal precedents—one for full moons, one for new moons, and maybe one for other times. The legal world would be turned upside-down, inside-out. It would be nearly indistinguishable from what we actually have. The arguments that work under a full moon in our actual world almost certainly wouldn’t work in this crazy possible world. Not only would they almost certainly fail to persuade, but they would almost certainly seem deluded or insane—probably as insane as arguments highly sensitive to the lunar calendar would seem in the actual world.
The good news is that upside-down, inside-out changes are rare. The bad news is that their rarity doesn’t equip us well for when they inevitably crop up. We forget that there are any such changes, especially when they’re not attended by frighteningly salient facts, like nuclear weapons. It is easier, in other words, to wrap our minds around how thoroughgoing theories like mutually assured destruction change our reasoning, forcing us to question very basic assumptions, if we can at the same time point to devastating bombs and mushroom clouds.
But there is nothing so salient as for the news. Layoffs and newspaper closings amid a wider economic downturn just don’t cut the mustard. Sometimes the differences looking forward a decade dwarf the differences looking back a decade.
When that happens, when the near history no longer contains implicit clues about the near future, we are unmoored, and we look to look to the differences between differences as a partial guide—but just come to terms with our own imaginations, just to maintain some footing amid upheaval. In order to grasp some sense of how sweeping the next decade of changes in the news business will be, we’ve got keep inching back through time and technology till we arrive at the gut feeling that the differences are equal. When the differences looking forward and the differences looking backward are equal—idealized, vaguely but substantively—we can look to see what is common between the past world and the future one. And those common facts or truths are the only facts and truths we can carry forward as precedent, more or less unquestioned.
As with many businesses facing disruption from the internet, it is far from clear that there is anything common between what the news business will see a decade forward and what it saw even a century back. This is a muddled exercise in which we accomplish little more than calibrating our intuitions about what to discard and what to keep. But there is so much to discard that our intuitions are critical.
My gut tells me this, nuclear holocaust notwithstanding: It is no longer reasonable to carry facts true about the history of the news business into the future without detouring through first principles about journalism and why it’s important. Nothing true of journalism in a decade’s time will turn out also to have been true of journalism at any time in the past except those facts that will always be true.
