On the Dangers of Homogeneity
One of the Eight Best Investing Blogs, Value Discipline, has an excellent new post entitled “The Dangers of Homogeneous Thinking.” Diversity of thought and interpretation is an important concept.
A lack of variation within any population is a dangerous thing. An evolutionary system in which an overall sense of conservatism (carrying what has worked in the past into the future) combined with a lot of variation at the margins (sometimes in extreme and eccentric ways) has often succeeded in consistently creating truly remarkable and effective outcomes that could never have been devised by a single omniscient actor.
This is something I spend a lot of time thinking about. Unfortunately, there is a tendency for success to sow the seeds of future failure, because the greatest enemy of great new ideas is acceptable old ideas.
Major League Baseball is an extreme example of a system in which variation is surprisingly stifled. I’ll use it, because although large corporate bureaucracies display some of the same attributes (and thus outcomes), any discussion of specific corporations would be both less concrete and somewhat more controversial – because it’s closer to the topic I normally write about here.
Pitching techniques are surprisingly uniform in Major League Baseball. There’s basically no evidence to suggest that any physical constraints should cause such bizarre uniformity. Historical evidence shows that other techniques are pretty effective. Furthermore, employing an unusual technique should be especially effective during a period in which a batter is highly accustomed to pitches thrown at different angles and speeds from a different release point following from a different motion. In other words, there’s a lot of evidence to suggest that pitching counter to a batter’s overall experience and his expectations of a certain situation should (all other things being equal) work better than pitching like everyone else does and like the batter expects (both generally and in a specific situation).
Anyway, pitching techniques don’t vary a lot in the major leagues today. Try to pick a range of speeds and a range of release points that will encompass a large percentage of all the pitches thrown in the major leagues. It’s not very hard to do. The range won’t be that wide. Why is this?
I’ve come to only one good conclusion. I’m not sure if it’s the right conclusion; but, it’s the best I can come up with for this very important question – and the question really is important, because a system like professional baseball should display a lot of variation in this regard if it works the way most such systems do.
My best guess is that it doesn’t. I think the relationship between the major leagues and the minor leagues is the answer. Not all professional baseball players are doing everything they can to win. Some are doing everything they can to advance.
There’s a huge difference between those two motivations. If winning is the key to success at all levels, then techniques (however …
