Even highly acclaimed research institutions and journals unfortunately care mainly about money and exposure. Sinclair undoubtedly creates research papers of high "impact" - in the sense that they are sensational and oft-cited. It's just that no one else can reproduce his findings and that the actual clinical impact is unimpressive. Moreover, while appearing reasonable at a glance, many of his statements fail under scrutiny - the text I linked by Brenner really does quite a good job in this regard.

There is (unfortunately) not a culture of actively trying to disprove the research of others in today's scientific research, even though it is in principle one of the pillars of science. The fact that Sinclair's claims are so over the top that they merit a response like this truly is special.
