All tests are extensions of the observer where the test is the means of approximating a natural environment by observing a specific list of variables which reflect the environment being tested. The test is a means of mimicking variables found in nature where the test itself cannot observe all variables within the natural environment given the variables observed are a projection of the tester's angle of awareness. The test is a projection of the observer and as such necessitates a subjective state of awareness.
This subjective state necessitates that all objective truth, truth which is agreed upon where multiple subjective states align, is grounded in the aforementioned subjectivity where what we deem as truth is fundamentally an angle of awareness, in this case group awareness. This angle of awareness necessitates that given any set of phenomenon only a specific number of variables are observed and the test itself does not address all potential variables.
This nature of testing thus necessitates what is being observed is a series of relationships determined by a series of subjectively observed parameters. These parameters are what is being measured and not the natural environment itself.
