GUEST,John Garst Origin Of John Henry--part TWO (240* d) RE: Origin Of John Henry--part TWO 22 Nov 11

On the logic of evidence:

Two tests of a hypothesis against an item of evidence, several items, or all of the evidence.

Weak Test
Given the hypothesis, is the evidence plausible?
(The hypothesis passes the test if the answer is "Yes.")

Strong Test
Given the negation of the hypothesis ("not hypothesis"), is the evidence plausible?
(The hypothesis passes the test if the answer is "No.")

Serious hypotheses made by serious and qualified individuals will always pass the weak test against the evidence that was available at the time the hypothesis was put forth, provided that all of the evidence was considered. This is why the test is weak.

On the other hand, hypothesis framed on the basis of *part* of the available evidence, or before new evidence was found, and hypotheses of incompetents or crackpots may fail the Weak Test.

Given a hypothesis that passes the Weak Test, the Strong Test discriminates between hypothesis and not hypothesis.

The best situation is that a hypothesis passes both the Weak and Strong Tests.
