Bad attacks/actions, lead to a false sense of security, the idea of getting something and "knowing" that it works. This is something I have written about before, but I have seen a number of videos posted in various places recently where this happens.
Poorly delivered attacks, where the body moves into distance before the weapon, allows many actions to carried out, which simply would not be able to happen if the attack was delivered properly.
Now part of teaching is to work with the scholar and deliver actions in such a way to provoke a certain response. However this is not what we generally see.
So a false attack is made and sense that the response works, is sustained, however false knowledge is being built on top of another layer of falsehood.
