That's the thing we should be discussing here. Not martial arts, but how such an asymmetry in information came about.

Now to answer your question: it is not about the amount of information, it is about one's belief. Belief has to be shaken from within; otherwise, opposite information from outside often only compound one's belief.
The belief in the traditional martial arts is a zen that to most it is an ultimate goal, not a reality. Defeating kung fu practitioners does not mean that true kung fu masters who obtained the zen can be similarly defeated.
Beliefs, culture, and faith are not in the scientific domain. And philosophically, it is questionable that currently accepted scientific domain is superior to beliefs, culture, and faith.
