Their business depended not on superior technology, but on the highest number of test runs and why you need to make things

They designed the machine, built it, and flew it. Their model depended not on superior technology, but on the highest number of test runs, creating an optimal learning curve. This revealed flaws to be worked on and gave them a feel for the product that could never be had in the abstract. The emphasis was not on the parts, but on the overall flying experience; not on power, but on control. Since money was a factor, supreme importance was placed on ingenuity in getting the most out of the least. The differences between the two approaches can be seen in the analogies they chose to base their designs on. The abstract thinkers opted for the ship analogy, working on the similarity of navigating an alien medium (water or air), which made them place importance on stability. The Wright brothers chose the bicycle, which emphasized the rider or pilot, the user-friendliness of the machine, and its overall functionality. Focusing on the pilot instead of the medium ended up being the right answer to the puzzle, because it led to the design of something that could be maneuvered. From that starting point, a more complex airplane could be easily evolved.

Mechanical intelligence is not a degraded form of thinking, as compared to abstract reasoning. It is in fact the source of many of our reasoning skills and creative powers. Our brain developed to its present size because of the complex operations of our hands. In working with resistant materials to create tools, our ancestors developed a pattern of thinking that transcends manual labor itself. The principles behind mechanical intelligence can be summarized as follows: whatever you are creating or designing, you must test and use it yourself. Separating out the work will make you lose touch with its functionality. Through intense labor on your part, you gain a feel for what you are creating. In doing this work, you see and feel the flaws in the design. You do not look at the parts separately but at how they interact, experiencing what you produce as a whole. What you are trying to create will not magically take off after a few creative bursts of inspiration, but must be slowly evolved through a step-by-step process as you correct the flaws. In the end, you win through superior craftsmanship, not marketing. This craftsmanship involves creating something with an elegant, simple structure, getting the most out of your materials—a high form of creativity.
