Not that I'm a Derek Lowe fanboy or anything but the entirety of your comment is like "that guy needs to check himself" without, like, any specific context, any specific argument he's wrong on this specific question or like anything. It's like "deciphering questions around credibility" is hard ... all the way down. Where's yours? What are you saying?
Isn't the comment in fact praising Derek Lowe as a science communicator? In the second paragraph OP is just posing the questions that one might have when reading about a field not your own, that highlight the importance of reliable science communicators.
It's a very confusing comment since Derek Lowe is a chemist working in pharma but is being referred to only as a science communicator which I suspect most people would consider to be an implicit insult.
Derek Lowe is someone whom I greatly admire and his work as a science communicator is a true service to the profession and to science at large. It is not intended as an insult in any way. I've known a great number of competent chemists, but few are as effective as communicators as he is.
I think it says more about the person reading it as an implicit insult than it does OP. I am, I think, a fairly competent scientist, and know many great scientists. I know very few great scientific communicators.
My apologies for the lack of clarity in my prior comment; it was composed in haste. To be clear, I am a bit of a Derek Lowe fanboy. I value the work that he does in offering insight on his areas of expertise to the public at large because he has both the necessary understanding and the ability to communicate clearly. Few people have his level of background knowledge alongside the capacity to wade into the depths of pharmaceutical chemistry and then communicate that information and his personal perspective to enrich the commons.
What I was getting at with the issue of credibility is that I (or most others) would have time determining if a particular scholarly author in pharma is a good person to listen to on the subject. But having evidence that Derek Lowe is an honest broker of information in that domain, given his long history of commentary as well as other chemists I know who eagerly read his commentary, I'm willing to defer to his assessment.
