Give this a read: http://en.wikipedia.org/wiki/Falsifiability

This is the scientific model he is referring to is a very solid tool in science for avoiding poor scientific claims.

Let's say Q is a scientific claim and let P be a logical consequence of Q. In other words: if Q then P.

Now the denial of the consequence takes the form:

if Q then P,
not P,
therefore not Q.

A good scientific claim should be falsifiable by the denial of the consequence. A bad scientific claim is one were there is no definable consequence where, if false, would prove the scientific claim is also false.

However, Q is not proven true by the "denial of the consequence"! Rather, Q is assumed true hypothetically. We can never prove Q is true, only potential prove it is false. The principle of falsification is a great scientific tool for avoiding poor scientific claims. If does not validate the truth of any scientific claims.
