@transform While appreciating your reply, it appears from the Wikipedia page that CCI broke off from RC which broke off from Dianetics. Co-counselling has its roots in Dianetics. I can't find anything which reports that any Dianetics-sourced techniques have achieved the same level of rigour that modern medicine has. I am referring to the transition in medicine from miasmas and humours to to the germ theory of disease and knowledge of the endocrine system, among other developments. Co-counselling deserves the same level of disbelief afforded to Dianetics. Given these two items, an increased level of scrutiny and skepticism is entirely appropriate for Co-counselling. https://en.wikipedia.org/wiki/Co-counselling
