The Right Answer?

It is strange how serendipity occasionally intervenes to link multiple lines of thinking and the conversations that go along with them and thinking on a subject crystallizes. In June 2014, Harvard Business Review published an article titled "Why Smart People Struggle With Strategy." The piece begins thus:

Strategy is often seen as something really smart people do — those head-of-the-class folks with top-notch academic credentials. But just because these are the folks attracted to strategy doesn't mean they will naturally excel at it. The problem with smart people is that they are used to seeking and finding the right answer; unfortunately, in strategy there is no single right answer to find. Strategy requires making choices about an uncertain future. It is not possible, no matter how much of the ocean you boil, to discover the one right answer. There isn't one. In fact, even after the fact, there is no way to determine that one’s strategy choice was “right,” because there is no way to judge the relative quality of any path against all the paths not actually chosen. There are no double-blind experiments in strategy.

When this crossed my digital desk this week, I was reminded of a slew of recent articles on the Service Academies (here, here, and here) and a great discussion that ensued on The Constant Strategist over the questions raised in the first of the linked articles. Here, two questions matter: What was the crux of the original issue and where have I landed in the overarching questions?

The initial online debate in this exploration centered on the curriculum most appropriate to the education of military officers. What should be the emphasis in a liberal education intended to develop them deliberately? There are two--one might call them adversarial--camps in this debate centered on the relative importance of the sciences and the humanities. I have always found myself standing athwart the apparent chasm between these two positions. As a military analyst with too many graduate degrees in math, I have enormous sympathy for the technical side of this debate (perhaps selfishly, since another position would invalidate much of my education and professional life). But I began my life as a student of English Literature and I spent a formative interlude as a graduate student in military history and strategy, and I know the technocrat's approach to conflict and strategic planning is problematic. But since it is hard to ask that everyone know everything, what is the right answer?

In the end, I think appropriate diversity is the answer, at every unit of analysis from the individual to the population. The trick is to ensure both expertise in the population (i.e., someone somewhere has spent a life studying the topics of interest) and familiarity in individuals (i.e., we have all studied enough of the other that we can speak a common language and seek useful metaphors). That means we should encourage and incentivize both expertise and exposure in a variety of disciplines--math, statistics, physics, chemistry, engineering, history, anthropology, theology, literature, etc. But there's a catch.

In our world of military operations research analysts so well trained in seeking optimality the idea of external familiarity really matters, and this is why I'm writing. There is a distressing and problematic bias in the technical fields toward the existence of a "correct" answer, not unlike the assertion in the Harvard Business Review piece. It's how we're trained. In our education, there exists a provably true answer (at least within the constraints of our axiomatic systems) to most of the textbook questions we answer as we learn our trade. This is, in fact, part of the reason for my own shift once upon a time between literature and math as a chosen field of study. Certainty has a certain comfort and led to fewer arguments between student and teacher.

I do NOT want to encourage anyone to not study the sciences, operations research, or (my own love) mathematics. And I do NOT want to encourage avoidance of the the less technical disciplines. Rather, what I want to encourage is an appreciation of contingency in the application of the technical disciplines and a rigor in the application of the non-technical disciplines, especially the context of militarily relevant questions.

Why? Fundamentally because our models and computational tools are by definition rife with assumptions. What if one or more of those assumptions are wrong? What if we forget some minor idea that turns out to be critical? What if our axioms don't work? (I'm looking at you, Economics.) What if optimality itself is a chimera?

For us, reading history of various kinds and actively considering the question of how our forebears (analytic and otherwise) erred is perhaps a useful remedy. The problem is not that one is smart or not. The problem is how and what one studies and with what intent.

The proverb says, "Iron sharpeneth iron." A suggested circular addendum to this wisdom is that the humanities temper the steel of the sciences while the sciences sharpen the analytic edge of the humanities.
