Peer reviewing is an important part of the scientific process and that's why trust is instilled into it.

The problem is that it has become very incestuous and narrow in their findings instead of welcoming criticism to their methods or conclusions.

At this point it's almost like, you pay two different people sums of money to agree with each other and then they'll agree that the finding is sound, and then it's considered "peer reviewed" while other objections are suppressed.
