Actually if you look into the entire Peer Review system that is the foundation of trust within our scientific communities, you will discover that they are acknowledging a very real and serious issue with centralised reviews of all kinds.
Money is buying power and can control reviews etc. I have a close contact with someone who owned her own dental clinic and spoke often to the corruption and problems she would face with dentists chasing $$ by "drilling & filling" rather then making care and prevention the focus.

I totally understand that you may not see the need for it, but I can say for sure that I do from my experience with dentistry and the medical community in general!

We need to be able to trust implicitly in our medical professionals, but with the industry so profit-driven and greed having its way, its just not possible right now.
Purely my opinion and by no means do i insist its the truth. :)
