> says Sarah McAnulty, a squid biologist and founder of Skype a Scientist who was not involved with the research. Something I have always wondered about articles on research papers. Is it the norm or standard that they always consult and expert in the same field that wasn't part of the research? why is this? I have seen this in many physics articles too. I am not against it as it seems purposeful.
