Definitions for "Falsifiability"
An indicator of the scientific status of a theory, in that it is in principle open to disproof. A good scientific hypothesis will make predictions about the world that expose it to refutation by empirical evidence.
See Falsifiability principle
The extent to which a particular theory can be tested and determined to be "false." Some critics of evolution believe that the evolution is not falsifiable.
The requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. This is a way of emphasizing the importance of an improbably outcome. To say that an explanation or an outcome is not falsifiable is to say that any observation at all is consistent with the explanation. And it is highly probable that we will have "any observation at all." So, an unfalsifiable explanation fails the improbable outcome test.
