The details are impressive in their regularity. All four beginning years of the 1870s sport high values of standard deviation greater than 0.050, while the last reading in excess of 0.050 occurs in 1886. Values between 0.04 and 0.05 mark the rest of the nineteenth century, with three years just below, at 0.038 to 0.040. The last reading in excess of 0.040 occurs in 1911. Subsequently, decline within the 0.03 and 0.04 range shows the same precision of detail by even decrease with years. The last reading as high as 0.037 occurs in 1937, and of 0.035 in 1941. Only two years have exceeeded 0.034 since 1957. Between 1942 and 1980, values remained entirely within the restricted range of 0.0285 to 0.0348. I’d thought that at least one unusual year would upset the pattern—that one nineteenth-century value would achieve late-twentieth-century lows, or one more recent year soar to ancient highs—but we find no such result. All measures from 1906 back to the beginning are higher than every reading from 1938 to 1980. We find no overlap at all. This—take it from an old trooper—is regularity with a vengeance. Something general is going on here, and I think I know what.
The decadal averages show continuous decline before stabilization in the 1940s. (A note for statistically minded readers: standard deviations are expressed in their own units of measurement—mouse tails in millimeters, mountains in megatons. Thus, as mean values rise and fall, standard deviations may go up and down to track the mean rather than record exclusively the amount of spread. This poses no problem for most of our chart, because averages have been so stable through time at about .260. But the twenty-point rise in averages during the 1920s and 1930s might entail artificially elevated standard deviations. We can correct for this effect by computing the coefficient of variation—one hundred times the standard deviation divided by the mean—for each year. Also listed are decadal averages for coefficients of variation—and we now see that apparent stabilization between the 1910s and 1920s was masking a continuing decline in coefficient of variation, as the 1920s rise in averages canceled out decline in variation when measured by the standard deviation.)
If my editors were more indulgent, I could wax at distressing length about more details and different measures. Just one final hint of a more interesting pattern revealed by finer dissection: the chart on the next page amalgamates the two leagues, but their trends are somewhat different. In the National League, variation declined during the nineteenth century, but stabilized early in the twentieth. In the American League, founded in 1901, variation dropped steadily right through the 1940s. Thus, each league followed the same pattern—the time of origin setting a pattern of decline for decades to come. Can we use existence or stabilization of declining variation as a mark of maturity? Did the leagues differ fundamentally during the early years of our century—the National already mature, the American still facing a few decades of honing and trimming the edges?
No one has invested more time and energy in the study of numbers than baseball aficionados. We have measures and indices for everything imaginable—from simple lists of at-bats to number of times a black shortstop under six feet tall has been caught stealing third on pitchouts by righties to left-handed catchers. Yet I don’t think that this most basic pattern in the standard deviation of batting averages has been properly noted, or its significance assessed. As I argued above, the biases of our upbringing force a focus on averages treated as things, and virtually preclude proper attention to variation considered as irreducible reality. The standard deviation is our base-level tool for studying variation—as fundamental as milk for babies and cockroaches for New York apartments. Yet, after decades of loving attention to minutiae of averages, we can still gain insights from an unexplored pattern in the very simplest kiddie measure of variation. What better illustration for my claim that our culture undervalues variation at its peril?
After this detail, I’ve earned the right to end with a bit of philosophical musing, ostensibly in the great decline-of-civilization tradition, but really a sneaky bit of optimism from the depth of my sanguine soul.
Each dot represents the standard deviation of batting averages for one year. While the mean has gone up and down with the whims of history and the vagaries of invention, the standard deviation has marched steadily downward at a decreasing pace, as shown by its ever slower drift to the left.
The message of this study in variation might seem glum, almost cosmically depressing in its paradox—that general improvement clips the wings of true greatness. No one soars above the commonplace any more. General advance brings declining variation in its wake; heroes are extinct. The small population of Europe yielded both a Bach and a Mozart in just one hundred years; where shall we find such transcendent geniuses to guide (or at least enlighten) our uncertain and perilous present?
I wish to propose, in closing, a more general framework for understanding trends in time as an interaction between the location of bell-shaped curves in variation and the position (and potential for mobility) of the limiting right wall for human excellence. This theme transcends sports (or any particular example), and our model should include mind work as well as body work. I suggest three rough categories, with a fundamental example for each, ranging from high to low potential for future accomplishment.
Consider science as a system of knowledge. In most areas, our ignorance is abysmal compared with our sense of what we might learn and know. The curve of knowledge, in other words, stands far from the right wall. Moreoever, the wall itself (or at least our perception of it) seems flexible before the growth of knowledge, as new theories suggest pathways to insight never considered previously. Science seems progressive since current ignorance provides so much space to its right, and since the wall itself can be pushed back by the very process that signals our approach. Still, one cannot avoid—with that special sadness reserved for recognizing a wonderful thing gone forever—the conviction that certain seminal discoveries established truths so central and so broad in import that we cannot hope to win insight in such great gulps again, for the right wall moves slowly and with limits, and we may never again open up space for jumps so big. Plate tectonics has revolutionized geology, but we cannot match the thrill of those who discovered that time comes in billions, not thousands—for deep time, once discovered, set the root of a profession forever. These are exciting days for biology, but no one will taste the intellectual power of a man alone at Downe—Charles Darwin reformulating all nature with the passkey of evolution.
I would place most sports, as well as musical performance, in a second category, where the best have long stood near an inflexible right wall. When we remove impediments imposed by custom (women’s sports) or technology (certain musical instruments), improvement may be rapid. But progress comes in inches of milliseconds for goals long sought and unimpeded (I doubt that Stern plays notably better than Paganini, Horowitz than Liszt, E. Power Biggs than Bach—and neither horse nor human male is shaving much off the mile run these days). The small contribution of this article lies in this second domain—in showing that decline in variation will measure improvement when relative standards mask progress measured against such absolute criteria as clocks.
Lest we lament this second category for its limited licenses in improvement, consider the painful plight of a third domain where success in striving depletes the system itself. The right wall of our first domain was far away and somewhat flexible, near and rigid (but still stable) in our second. In this third domain, success hits the wall and consumes it—as if the mile run had disappeared as a competitive sport as soon as one hundred people ran the distance in less than four minutes. Given an ethic that exalts perennial originality in artistic composition, the history of music (and many other arts) may fall into this domain. One composer may exploit a basic style for much of a career, but successors may not follow this style in much detail, or for very long. Such striving for newness may grant us joy forever if a limitless array of potential styles awaits discovery and exploitation. But perhaps the world is not so bounteous; perhaps we’ve already explored most of what even
a highly sophisticated audience can deem accessible. Perhaps the wall of an intelligible vanguard has been largely consumed. Perhaps there is a simple solution to the paradox of why we now generate no Bach or Mozart in a world far larger, with musical training provided for millions more. Perhaps they reside among us, but we’ve consumed all styles of expression so deeply tuned to the human soul. If so, I might timidly advance a truly reactionary proposal. The death of Mozart at thirty-five may have been the deepest tragedy of our cultural history (great scientists have died even younger, but their work can be done by others). We perform his handful of operas over and over again. We might be enjoying a dozen more—some counted as the most sublime of all musical works—if he had survived even to fifty. Suppose a composer now lived who could master his style and write every bit as well. The ethic of originality forbids it absolutely, but would the integrity of art collapse forever if this person wrote just a few more great pieces in that genre? Not a hundred, just three or four to supplement Don Giovanni and Die Zauberflöte. Would such an addition not be esteemed a public service beyond all others?
Enough. I’m waxing lugubrious, despite promises to the contrary. For while I may yearn to hear Beethoven’s Tenth Symphony, I don’t lament a lost past or decry a soft present. In sport, and art, and science (how I wish it were so in politics as well), we live in the best world we’ve ever known, though not in the best of all possible worlds. So be it that improvement must bury in its wake the myth of ancient heroes. We’ve exposed the extinction of .400 hitting as a sign of progress, not degradation—the paradoxical effect of declining variation as play improves and stabilizes, and as average contestants also approach the right wall of human limits.
Do not lament the loss of literally outstanding performance (largely a figment, in any case, of failings among the ordinary, not a mark of greater prowess among the best). Celebrate instead the immense improvement of average play. (I rather suspect that we would regard most operatic performances of 1850, and most baseball games of 1900, as sloppy and amateurish—not to mention the village squabbles that enter history as epic battles.) Do not lament our past ease in distinguishing the truly great. Celebrate instead the general excellence that makes professional sports so exciting today. And appreciate the need for subtlety and discernment that modern fans must develop to make proper asessments; we must all now be connoisseurs to appreciate our favorite games fully. Above all, remember that the possibility for transcendence never dies. We live for that moment, the truly unpredictable performance that shatters all expectation. We delight all the more in Dwight Gooden and Larry Bird because they stand out among a panoply of true stars. Besides, I really wrote this article only because I have a hunch that I want to share (and we professor types need to set context before we go out on a limb): Wade Boggs is gonna hit .400 this year.
The Streak of Streaks
Book reviewed:
Streak: Joe DiMaggio and the Summer of ’41 by Michael Seidel
My father was a court stenographer. At his less than princely salary, we watched Yankee games from the bleachers or high in the third deck. But one of the judges had season tickets, so we occasionally sat in the lower boxes when hizzoner couldn’t attend. One afternoon, while DiMaggio was going 0 for 4 against, of all people, the lowly St. Louis Browns (now the even lowlier Baltimore Orioles), the great man fouled one in our direction. “Catch it, Dad,” I screamed. “You never get them,” he replied, but stuck up his hand like the Statue of Liberty—and the ball fell right in. I mailed it to DiMaggio, and, bless him, he actually sent the ball back, signed and in a box marked “insured.” Insured, that is, to make me the envy of the neighborhood, and DiMaggio the model and hero of my life.

I met DiMaggio a few years ago on a small playing field at the Presidio of San Francisco. My son, wearing DiMaggio’s old number 5 on his Little League jersey, accompanied me, exactly one generation after my father caught that ball. DiMaggio gave him a pointer or two on batting and then signed a ball for him. One generation passeth away, and another generation cometh: but the earth abideth forever.
My son, uncoached by Dad, and given the chance that comes but once in a lifetime, asked DiMaggio as his only query about life and career: “Suppose you had walked every time up during one game of your fifty-six-game hitting streak? Would the streak have been over?” DiMaggio replied that, under 1941 rules, the streak would have ended, but that this unfair statute has since been revised, and such a game would not count today.
My son’s choice for a single question tells us something vital about the nature of legend. A man may labor for a professional lifetime, especially in sport or in battle, but posterity needs a single transcendent event to fix him in permanent memory. Every hero must be a Wellington on the right side of his personal Waterloo; generality of excellence is too diffuse. The unambiguous factuality of a single achievement is adamantine. Detractors can argue forever about the general tenor of your life and works, but they can never erase a great event.
In 1941, as I gestated in my mother’s womb, Joe DiMaggio got at least one hit in each of fifty-six successive games. Most records are only incrementally superior to runners-up; Roger Maris hit sixty-one homers in 1961, but Babe Ruth hit sixty in 1927 and fifty-nine in 1921, while Hank Greenberg (1938) and Jimmy Foxx (1932) both hit fifty-eight. But DiMaggio’s fifty-six-game hitting streak is ridiculously and almost unreachably far from all challengers (“Wee Willie” Keeler and Peter Rose, both with forty-four, come second). Among sabremetricians (a happy neologism based on an acronym for members of the Society for American Baseball Research, and referring to the statistical mavens of the sport)—a contentious lot not known for agreement about anything—we find virtual consensus that DiMaggio’s fifty-six-game hitting streak is the greatest accomplishment in the history of baseball, if not all modern sport.
The reasons for this respect are not far to seek. Single moments of unexpected supremacy—Johnny Vander Meer’s back-to-back no-hitters of 1938, Don Larsen’s perfect game in the 1956 World Series—can occur at any time to almost anybody, and have an irreducibly capricious character. Achievements of a full season—Maris’s sixty-one homers, Ted Williams’s batting average of .406, also posted in 1941 and not equaled since—have a certain overall majesty, but they don’t demand unfailing consistency every single day; you can slump for a while, so long as your average holds. But a streak must be absolutely exceptionless; you are not allowed a single day of subpar play, or even bad luck. You bat only four or five times in an average game. Sometimes two or three of these efforts yield walks, and you get only one or two shots at a hit. Moreover, as tension mounts and notice increases, your life becomes unbearable. Reporters dog your every step; fans are even more intrusive than usual (one stole DiMaggio’s favorite bat right in the middle of his streak). You cannot make a single mistake.
Thus Joe DiMaggio’s fifty-six-game hitting streak is both the greatest factual achievement in the history of baseball and a principal icon of American mythology. What shall we do with such a central item of our cultural history? Michael Seidel’s happy response is a book devoted not to generalities or implications of the streak—many have done this, too many times—but to day-by-day details of how a man gets from one to fifty-six with no misses in between. This book chronicles the intricate factual events of DiMaggio’s achievement, and pays the best kind of proper respect, while providing the right sort of description. I shall return to Seidel, but first let me illustrate another approach to such an icon.
Statistics and mythology may seem the most unlikely bed-fellows. How can we quantify Caruso or measure Middlemarch? But if God could mete out heaven with the span (Isaiah 40:12), perhaps we can say something useful about hitting streaks. The statistics of “runs,” defined as continuous series of good or bad results (including baseball’s streaks and slumps), is a well-developed branch of the profession, and can
yield clear—but wildly counterintuitive—results. (The fact that we find these conclusions so surprising is the key to appreciating DiMaggio’s achievement, the point of this article, and the gateway to an important insight about the human mind.)
Start with a phenomenon that nearly everyone both accepts and considers well understood—“hot hands” in basketball. Now and then, someone just gets hot, and can’t be stopped. Basket after basket falls in—or out as with “cold hands,” when a man can’t buy a bucket for love or money (choose your cliché). The reason for this phenomenon seems clear enough; it lies embodied in the maxim: “When you’re hot, you’re hot; and when you’re not, you’re not.” You get that touch, build confidence; all nervousness fades, you find your rhythm; swish, swish, swish. Or you miss a few, get rattled, endure the booing, experience despair; hands start shaking, and you realize that you shoulda stood in bed.
