A Theory of Key Points: What Tennis can tell us about Technological Change

Blog September 29, 2013 9:24 am

One of the reasons for this blog is that it allows me to write speculative posts that no self-respecting journal would publish.  Consider this one of them.  I love watching tennis matches — and rewatching them on YouTube (typically when I have a deadline and I feel like doing anything but working on it).  And I often spend time thinking about technological determinism — or rather, how to avoid it in one’s work.  How can one tell stories of change without emphasizing the technological?  Or by folding the technological into the institutional?  It struck me once that telling a story about change is like predicting the winner of a closely fought tennis match.  Players and tennis analysts often comment that closely fought tennis matches come down to a few “key points.”  But what are these key points?  And how does one decide them?    I realized that the experience of watching a tennis match is totally different when you watch a match for the first time (“live”) and when you watch it already knowing the outcome.  And deciding on what the key points of a match are — knowing its outcome — is every bit as tricky as thinking about predicting which way a match will go when it is live.   What follows is a speculative exercise comparing the doing of history with the detection of key points in a match when you already know the outcome.

Coming into the 2011 US Open with a track record of winning all but one of the Grand Slam matches that he played that year, Novak Djokovic was facing Roger Federer in the semi-finals, the very man who had beaten him in his (Djokovic’s) only Grand Slam loss of 2011. And ominously, he lost the first two sets, 6-7(7), 4-6 before rallying to take the next two 6-3, 6-2.  It was now the final set and Federer, having just broken Djokovic’s serve in the final set to go up 5-3, was serving at 40-15, with two match-points on his own serve.  Upset at the crowd which was cheering Federer on wildly, Djokovic seemed out of sorts, angry at himself, perhaps, for being in this position despite playing a flawless third and fourth set.

[See the video from the first minute.]  The interpretation of what happened next remains a matter of dispute, hotly debated in tennis forums, YouTube comments, and the blogosphere.   Serving from the ad-court, Federer served out wide to Djokovic’s forehand. It was not a bad serve, but Djokovic swung at it hard, and literally smashed it cross-court for a clean winner. There was shocked silence for a second before cheering erupted. Djokovic walked to the other side of the court, raised his hands and looked at the crowd. Appreciate me, he seemed to be saying. The crowd obliged even as a bemused Federer stood waiting to serve on the other side of the court.

It was still match-point.  Federer threw a good serve straight at Djokovic’s body, and a rally ensued, which ended, heartbreakingly for Federer, with his shot striking the net-chord and then dropping back on his own side.  Deuce.  Djokovic went on to win the game breaking Federer in the process.  He then won the next three games as well, winning the final set 7-5 to defeat Federer and reach the final. 

 What was going on in Djokovic’s mind when he hit that screaming forehand winner off Federer’s serve?  Was it hit in anger or was it a calculated risk?  How much did Djokovic’s gamesmanship – seeking the crowd’s approval – affect Federer on his next serve?  Tennis fans and analysts continue to debate this.  My own thought, as I was watching the match, was that Djokovic, who can often be peevish and irritable on court, was angry with himself and swung at the ball, more out of pique than anything else.  But the shot went in, and Djokovic used it to rally the crowd to his own side.  On the other side of the net, Federer suffered a dent in his own confidence, and this allowed Djokovic (who is undoubtedly the best and fittest player on the tour today) to put himself back into the match. 

Both players themselves offered contradictory interpretations of the return.  “It’s a risk you have to take,” Djokovic told Mary- Joe Fernandez in the on-court interview. “It’s in, you have a second chance. If it’s out, you are gone. So it’s a little bit of gambling.” Federer, on the other hand, was having none of it.  “Confidence, are you kidding me?” he scoffed in his post-match interview. “I never played that way. For me, this is very hard to understand how you can play a shot like that on match point.”  He continued: “To lose against someone like that, it’s very disappointing, because you feel like he was mentally out of it already. Just gets the lucky shot at the end, and off you go.”   Djokovic acknowledged that he needed to “get some energy from the crowd.”  “Look, I was a little bit lucky in that moment because he was playing tremendously well with the inside-out forehand throughout the whole match. This is what happens at this level. You know, a couple of points can really decide the winner.”

The Federer-Djokovic first match point is often what both tennis players and tennis analysts refer to as a “key point.  These key points, as Djokovic points out in his post-match interview, are often the ones that “decide the winner.”  In the rest of this post, I want to show how this idea of “key points” as relevant to the outcome of a tennis match helped me think about doing the history of technology.

What is a “key point”?  A key point is a point (possibly among a set of points) which can be seen to have determined the outcome of the match, as seen by the players or the analysts (or both).  Players often sense that a point will be key during the match itself and go all out in their effort to win it, perhaps by hitting extra hard, taking a risk, or by running down a ball they would rather have left alone to conserve their energy.  Analysts too, as interested observers of a match, can sense whether a point will be key to the outcome, although they have no agency when compared to the players themselves. 

But while an upcoming key point can be sensed by the players and the spectators, key points can be definitively identified only after the match is over.  In other words, the identification of key points is contingent on the outcome.  In the Federer-Djokovic match we saw above, the courageous (or reckless) Djokovic return at 15-40 is a key point only because Djokovic won the next four games to win the match.  If Djokovic had lost the next match-point, this point would no longer be talked about as a key point but as a fluke.  Instead the game in which Federer broke Djokovic at 4-3 in the final set would have turned out to be the key to the outcome of the match.  To restate this point, the key to winning a match is to win the key points, but the points that are key to winning a match can only be determined after the match is won (or lost).   [This is essentially a Latourian point: mobilizing "actants" is the way of building both technology and society; but it isn't clear what needs to be mobilized until an outcome is achieved.  When in the making, the technical and the political are often hard to tease apart.]

It is worth discussing an alternative explanation of match outcomes: that the more talented, or better, player wins the match.  I quoted a part of Djokovic’s post-match interview above.  On actually watching the interview, it turned out that the quote left out a crucial part.  Djokovic actually said: “This is what happens at this level – when two top players meet.   You know, a couple of points can really decide the winner.”  [Italics mine.]   The implication here is that it is only when players are evenly matched in terms of “talent” that the outcome hinges on a few key points.  When players have wildly different talents, the outcome hinges on, say, the “talent” they possess (which will not be the same) and not on the key points.

How might the key point analytic relate to what historians – especially historians of technology – do to understand the past?  As I see it, the topic of historians of technology is technological change.  Our aim is to understand the past and to answer the question: why do certain things change while others remain the same?  One might see this question as similar to those that tennis analysts pose to themselves: why did player X win against player Y?  Why has player X consistently beaten player Y in their previous 5 matches? 

Somewhat analogous to the two theories to explain the outcome of a tennis match – the “key point” theory vs. the “more talent” theory – one could oversimplify theories about technological change into two kinds.  One theory might be that technological change happens because a certain technology is better at producing certain desirable outcomes (more profits, more efficiency, better living conditions, progress and so on).  This theory would go under the name of “technological determinism” and would be similar to the “more talent” theory of tennis match outcomes.  The other theory would postulate that technological change happens because certain groups of people -– I will call them “interest groups” -– are able to defeat, or persuade, their opponents through the channels available to them at certain crucial junctures.   This theory would be similar to the “key point” theory.

How would the “key point” theory of technological change help avoid the pitfalls of technological determinism?  As I see it, the main dilemma of any social science is the issue of predictability.  Unlike the natural sciences which can predict the future behavior of their “actors” (the trajectory of a missile, the motion of the planets, the quantum states of atoms), the social sciences cannot (and with good reason) predict the changes of the future.  They cannot because assemblages of human actors are unpredictable.  They have agency.  Harry Collins has shown how even the behavior of natural scientists – who produce natural science, the most “rational” of all the disciplines – is still unpredictable, and is better understood as the application of certain tacit skills, than as the brute application of some rule-bound “scientific method.” 

The social sciences thus face two different questions.  On the one hand, social scientists need to account for the sense of contingency and unpredictability that their actors often feel while thinking about the future.  They also need to account for why their actors feel that certain actions are the key to changing the future.  On the other hand, they (and here I speak of historians in particular) need to account for why the events of the past seem so inevitable, the way they seem to lead to the present so unproblematically.  Clearly actors in the past who experienced these “same” events did not know how things would turn out.  How can historians account for the inevitability of the past for us and its contingency for the actors experiencing the past?     

A theory of technological change that looked at “key points” as determining certain (technological/social) outcomes could be one solution to this.  Key points in history would need to have the following characteristics.  First, historical actors themselves should have some dim awareness that something important was happening and that different visions of the future are at stake.  Second, the outcomes of these key points should result in the victory of one set of interest group over others, thereby setting in motion a certain kind of future.  Third, these key points can only be determined retrospectively once the outcome is known (as historians always do).  Fourth, key points preserve the agency of historical actors.  Finally, key points in history can change as newer and newer outcomes arise.  For example, historians now agree that Barry Goldwater’s defeat by Lyndon Johnson in the 1964 presidential election, and the subsequent rise of grass-rootsconservatism, is a key to understanding American politics today, even if no one seemed to be paying attention to it back then.  It was a key point for certain actors who were mobilizing to achieve their vision of the future, even if their ideological opponents were largely unaware of them.  

Tennis key points are heuristics, of course.  And they have their limitations, even in sports.  For instance, it is much more difficult to locate key points in soccer, for instance, where the notion of discrete points does not exist.  Soccer is, for lack of a better word, continuous, while tennis is more discrete, with precisely demarcated “points.”     And even in tennis, determining key points is difficult.  Because one point seemingly leads to the next: if the Djokovic screaming forehand winner was a key point, what about the points before that one?   What about those that decided the first four sets?  Would it have mattered if Djokovic had won the first set–which he lost narrowly in a tie-breaker (9-7)?

But I do think that determining the key points of a tennis match is like doing history.  The boiling down of a match outcome to a series of key points shows us how contingent events are.  And at the end of the day, match outcomes are predictable to some extent: a match between Federer and David Ferrer is far likely to lead to a Federer victory (although not always).  Those are the kinds of explanations/narratives of technological change that the key point theory would ask us to look for: highly contingent, built out of specific events, but with specific patterns that are by no means law-like.
