The authors, reviewers, editors and commenters of these studies work within a “Filter Bubble” that needs to be exposed and broken to prevent the ability of dubious studies to be published and promoted – unfortunately the bubble extends to include members of the public, most of whom are not qualified to personally understand and evaluate study limitations.
 

 Authors and co-authors, Reviewers, Editors and Commenters of the 50 anti-F neurological studies listed below
The four studies singled out by Connett & referenced in Ken Perrott’s article above are red-highlighted in the list of studies.

Those who have contributed to more than five of the 50 studies are highlighted.
