If not, then let me know. Let me get started by defining two classes of people. The scruffy class of people consists of very practical individuals. They believe it is more important to show results than it is to carefully develop theories, and prove the theories are true. To me scruffies epitomize the process of invention.
Extreme scruffies are mad scientists.
The neat class of people consists of individuals who find it very important to be formal in their approach to experimentation. A neat requires every i dotted and t crossed. Without a formal consecrated theory an extreme neat may not be willing to proceed to implement the theory. The world needs neats and scruffies. I want to experiment and see if it works.
