I have sometimes wondered whether posts on SN could be seen as 'peer reviewed'.
One of the definitions of Peer Review is,
self-regulation by qualified members of a profession within the relevant field
Although, there are users who could fit within this definition, the vast majority of people, myself 100% included, are still riding around with our training wheels on. But that should be seen as not just okay, but it should be welcomed.
'Student' posts can't have the same credibility as 'professional' peer reviews in Medical reviews or Industrial reviews - sure. But, in a way, it can be seen a positive - we've got something that these professional peer reviews might never have - allowing the 'Beginner's Mind' or Shoshin to pervade around us and around the subject.
The practice of shoshin acts as a counter to the hubris and closed-mindedness often associated with thinking of oneself as an expert. This includes the Einstellung effect, where a person becomes so accustomed to a certain way of doing things that they do not consider or acknowledge new ideas or approaches. The word shoshin is a combination of sho (Japanese: 初), meaning "beginner" or "initial", and shin (Japanese: 心), meaning "mind".
The Einstellung effect, mentioned above, can be described as:
the development of a mechanized state of mind. Often called a problem solving set, Einstellung refers to a person's predisposition to solve a given problem in a specific manner even though better or more appropriate methods of solving the problem exist.
Although many of us might not know a bit from a byte a lot of the time, there's a symbiosis in which those who are far more advanced amongst us can benefit from our naivety - our beginner's mind - almost as much as we, the more lowly, can benefit from them.
We all started out with complete ignorance from the subject. It's good to keep fresh and honest about where we came from and see ourselves in them.
Technology owes a lot to innovation and evolution. Having a bit of randomness here and there, while evolving, always helps.
