This covers all issues surrounding reproducability pretty well. It is astounding that scientists want to hide behind their expertises when their results and conclusions are being tested. Biologists who are under a similar cloud tried the same tactics too. They have some secret sauce that make their lab and experiment special and unique, beyond the comprehension of mere mortals. Of course, as publically funded scientists they have a moral if not legal obligation to disclose their "secret sauce" if that is very important. Why publish a paper but leave the public in dark about the most important factor? At best it is an oversight, at worst it is dishonst.
Experiment and reason underpin the modern science. Common sense says inreproducible experiments call their colusions into question. Scientific experise is no escape from reason. A fancy degree from a "top" university does not make infallible anyone. Well controlled experiments are the final arbitrator.
