I Suppose that's it really. . . they are trying to deal with stuff that is unknown, unquantified, and completely open to criticism until sound results are quantified.Peer review is something that is used in assessing articles submitted to scientific journals, it doesn't apply to work in progress. Most of the specialist experts employed in the series such as drone operators, tunnelling machine owners, astronomers, and local universities that are often used to analyse samples, have no interest in such matters. It is also worth asking, what journals would they submit reports to? There are relatively few journals that deal with "paranormal" subjects, I suppose the Journal of Scientific Exploration would be the obvious choice.
