You're right that this could be on some of the studies, but it's wider spread than that. There are studies on studies. The one that I was able to find that is kind of relevant is “Why Most Published Research Findings are False” by John P. A. Ioannidis.
I'm not sure if you've seen or know of this study. It looks at the topic thoroughly—even with the data, there's a lot of research that gets done that we can't replicate.
There are issues there and I'm not sure how the capstone would correct it.
I'll let the other witness comment on this issue.
