null testing?

Null results validate theories that predict null results
and invalidate theories that predict positive results.
A well-known example from the history of science
would be the scientific tests that were used to look for

Physics theory is usually ahead of empirical findings.
Another way of saying imagination and art are more
insightful for explanations rather than just relying on
observations alone.
