I agree that it's a filter for someone that has put in the work to learn the research, which is very helpful. But my take is if a guy can go and sell 2 million books and the PhDs get in a tizzy because he doesn't have a PhD, and the lay person can't tell the difference, then the problem is these whining "PhD experts" and their pseudoscience, and not the non-PhD who wrote the book. The layperson can immediately tell whether a phone was made by electrical engineering experts or some crank amateur. If someone is buying some "fraudsters" theory over some PhD's, perhaps it's because neither of them work so it doesn't really matter. My take on the field of psychology (and many human bio fields) is we just don't have the scientific tools yet to make it a true science. But technology is finally making in roads (ie, wearables), so perhaps there's hope yet.
