I talk about the problems with Fiske and you say:
"Cuddy herself, in the linked article, even asks: "Why not come to a conference or hold a seminar?""
I am not criticizing Cuddy. Fiske is editor of PNAS, former president of APS, and is putting her criticisms in APS Observer. The difference between a journal and an official magazine of a scientific organization is irrelevant in this concept, in that the supposed superiority of an edited journal is what is in question here when the editor is not good, and is not considering the context of the discussion.
I am pointing out the utter hypocrisy in her argument that you shouldn't point out statistical errors on blogs, while she is pointing this out in a publication she controlled. She wants people to be able to protect their undeserved status, it is clear.
The entire idea that science needs to be locked up in limited access journals (or magazines) is not a good one. The real issue is that the quality of PNAS has been pretty low. Fiske's response to that is to try to discourage open criticism. Open data is one of the reasons that people were able to find these errors. Resistance to publishing failed replications is not proper behavior. We have now seen PNAS publish a few letters describing errors, and hopefully the standards will improve. However, it hardly seems like a person whose response is to lean toward hiding the discourse is the right person to do it?
