Razor #7: Popper’s Falsifiability Principle

Popper’s Falsifiability Principle:

For a theory to be considered scientific,
it must be falsifiable.


Even the scientific are called theories
as they might be invalidated in time,
by other theories that seem more valid later,
in the quest for truth.


(In philosophy, a razor is a principle or rule of thumb that allows one to eliminate (‘shave off’) unlikely explanations for a phenomenon, or avoid unnecessary actions.)
