Looking back to data, we can see if the consequences are plausible; looking forward to theory, we can see if general principles are suggested.

Unwrapping occurs when the "solution" is explicitly built into the program from the start.

If there is to be a competition, there must be some basis for resolving it. It is also clear that the competition should be experienced based.
