Why use metaphors?
Metaphors do not substitute for proof. They are optional. They are only supposed to help understand some concepts based on systems science, control theory, optimization, etc.
For example, many people believe that kids left to their own devices are bound to waste time on videogames or similar pursuits. It is helpful to know that self-directed learning can actually lead to well-rounded knowledge. This is a process than may take a decade or two. Well-roundedness comes from knowledge convergence that can be derived from memetic science. At the root of that phenomenon is an evolutionary process in which learning decisions powered by the learn drive determine the directions in which the knowledge tree grows.
As much as learning decisions shape the knowledge tree, business decisions shape the markets. Most people are familiar with how economies work. This is why a metaphor that compares the school system to a communist system may be more convincing than a mass of brain and information science titbits that lead to the same realization (see: Modern schooling is like Soviet economy).
I cannot be sure my metaphors are effective, however, I hope there are at least not harmful. If you see dangers, let me know. If you understand the text, you can safely skip the metaphors.
Some metaphor examples:
- School system as a communist system
- Students as puppies
- Knowledge as a crystal
