Unfortunately, I'm not. When we formally went through this (risk of bias and GRADE level) in exquisite detail on the old old forum for the ganzfeld studies, we discovered that the risk of bias was higher and the GRADE level lower than our intuition (mine and proponent scientists) would lead us to believe. I agree that the quality has some similarities to psychology research, but recent investigations have shown that some of it also has problems with low evidentiary value. The same sorts of reforms that mainstream research is undertaking can also be applied to parapsychology.
