'Beliefs' in the martial arts

Matters of 'faith' seem to permeate just about everything in our society. Rather than start bashing Christianity or Islam for my first blog attempt, I would rather bring to light something that is very similar.  As a person that is always in search of knowledge and truth when it comes to matters of science, I share the same 'belief' when it comes to knowledge and truth in the martial arts.  If someone tells me they are a master baker, I naturally assume they can bake a cake. If someone tells me they are a physicist, I naturally assume they could intuitively demonstrate there knowledge of basic Newtonian mechanics. If someone tells me they are a martial arts master, naturally they should be able to, crudely put, whoop someones @ss.  Right?  However just as there are many scientists, there are also 'pseudoscientists'.  It's the same in martial arts.  In the scientific world, they have what is called 'peer review', which is a process where if someone makes a scientific claim, others in the scientific community will try their hardest to verify if the claim is true or not. Well, in the martial arts community, we also have a 'peer review', which entails putting on gloves, headgear and a mouthguard, and then backing up your claim or exposing someone else's claim as falsifiable.  Yet there exist many claims that have yet to be backed up by physical evidence and reasoned logic. They have not proved themselves or their claims through our 'peer review'. Yet they have many followers who pay good money for their superstitious nonsense.  Sound familiar?
