Master the compulsories+ and we allow (and fund) a broader scope of work...
The amoeba diagram is used to illustrate how we often limit our thinking to within a narrow scope (the nucleus) when in reality there is much more flexibility and freedom available to those willing to take chances. Rules and regulations are set up based on a historical precedent, and by knowing the precedent we dare to step outside the nucleus. The first to take the step has much more freedom in the pursuit for blockbuster+ products.
We know that you know when it’s time to stop. A key part of the compulsories is being able to intuit whether or not a line of inquiry is still worthwhile. This is an intuition based on time and resource constraints: we are not an open-ended academic pursuit. It may be that Mother Nature may someday make what you’re working on worthwhile, but given our industrial constraints, we go with what we know today.
