Fred, thanks for sending this particular blog link. I read it over lunch and came away disheartened. The author (whom I can't identify from the blog) criticized Lehrer for sweeping generalizations but then himself wrote the following:
"The problem isn't that the Decline Effect happens in science; the problem is that we think psychology and ecology and economics are sciences. They can be approached scientifically, but their conclusions cannot be considered valid outside of their immediate context."
"The problem isn't the Decline Effect, the problem is you believed the data had the force of F=ma. No one should be surprised when medical "truths" turn out to be wrong-- they were never true to begin with."
"And the moment you talk to The New Yorker, your misinterpreted statistical association becomes truth."
So I think the blogger here is ranting against the popular press (and scientists who talk to the popular press) and how it reports on findings too early and too flippantly. But he also seems to be dismissing all empirical research and, in particular, dismissing all research excepts physics.
Some of the studies described by Lehrer are rigourous meta-analyses, synthesized across multiple studies. They are not "n = 4 studies" (to use another quote from the blog post). In this post I do not see a substantive criticism of the studies that Lehrer discusses as a basis for his views.
As somone interested in the exchange of knowledge between science and practice, I come away thinking that the blog author believes there is no truth and no value in scientists trying to explain their findings to a broader public. This seems to me to be a nihilistic view of all social science, rather than a targeted criticism of the Decline Effect.
Maybe I missed something?
Ken

In relation to the article Gary posted, here's one that takes a critical view of the claims made in it.
