Problems With the Rational Model

In our previous discussion of mental models, we talked about two types of models. In this post I want to divert and discuss some problems and limitations that come from applying the Rational Model approach. Many people, especially those with technical backgrounds, will equate systems thinking with a rational approach. 

In the seminal management book, In Search of Excellence,Thomas J. Peters and Robert H. Waterman Jr., found issues with the Rational Model when they studied the excellent companies. This was a particularly interesting part of the book to me (In Search of Excellence, Chapter 2). It was obviously important to them to devote an entire chapter to it’s limitations and fallacies. They uncovered what they summarized were several significant issues, all of which the excellent companies had learn to overcome; 
1. The numerate, analytical component has an in-built conservative bias. Cost reduction becomes priority number one and revenue enhancement takes a back seat.
2. The exclusively analytic approach leads to an abstract, heartless philosophy.
3. To be narrowly rational is often to be negative.
4. Rationality does not value experimentation and abhors mistakes.
5. Anti-experimentation leads inevidently to overcomplexity and inflexibility.
6. The rationalist approach does not celebrate informality.

I believe that there is a prevalence of this mentality afflicting our society today. The reductionist approach of the Rational Model leads to complexity by attempting to continue to break down issues into their constituent parts. This is meant to simplify, yet indeed it tends to introduce complexity. This has been driven in large part by our rapid march toward technological "progress". Our minds tend to want see the world as “fixed”, and want to reject randomness that exists in nature. We automatically want to place data "in it’s place”. Technology only feeds this feeling, or instinct, of a rational fixed pattern or product. As Peters and Waterman rightly observed, this can lead to complexity and inflexibility in our lives. It is also dangerous in that it can cause us to adopt a “heartless philosophy” toward the randomness (read messiness) that is real life. 

Another real danger of this is the loss of beauty. Complexity that is simply described is beauty. The celebration of form over style, function over utility, or more over enough, can lead us to crowd out our appreciation for the simple beauty of our messy world. In 2007, Gene Weingarten published an article in The Washington Postabout an accomplished violinist playing six classical pieces in the L’Enfant Metro station in Washington, DC during rush hour. Approximately 1,097 people passed by Joshua Bell, one of the finest classical musicians in the world while he played some masterpieces that have endured for centuries. This was a free performance of pure art, but very little was noticed or acknowledged by the passing crowd. Weingarten writes, “In the three-quarters of an hour that Joshua Bell played, seven people stopped what they were doing to hang around and take in the performance, at least for a minute. Twenty-seven gave money, most of them on the run -- for a total of $32 and change. That leaves the 1,070 people who hurried by, oblivious, many only three feet away, few even turning to look.” Many, if not most, of those passing by are well-educated, well-paid professionals associated in some way with the Federal Government. Yet, they did not bother to appreciate what they were passing by. Does this mean that beauty is not appreciated? Is it too hard to understand or is not relevant to our busy lives? If so, then indeed our priorities have been flipped on end, and how Rational is that really?

So if we can integrate our priorities around our life and work, we may depart from a Rational model view. A paradox is by being a little “irrational”, we can be whole.
