disconfirmation

Introduction of evidence which conclusively establishes that a belief or hypothesis is not true or which diminishes the acceptability of a belief or hypothesis.

Once we move our search to the region of the mind, we find that access to the facts becomes much more difficult; as a result, disconfirmation is largely out of reach and metaphor begins to flourish.

A particular fact, observation, or other item of evidence which shows or tends to show that a belief or hypothesis is not true.

One can reduce the disconfirmations of economic generalizations by specifying a margin of error.
