OK, now I know you are not serious
"It would be much easier for me to see CRM in a more beneficial light if someone could direct me to the following: The research describing the original observations and how the CRM protocols were developed; descriptions of the initial trials where a strict protocol was applied to a randomly-selected group of participants and quantitative measurements of their effectiveness were gathered; and the subsequent studies performed by other researchers/bodies (using the original/modified protocol) that replicated the initial findings and followed the participants longitudinally (over time) to determine the long-term efficacy of the CRM treatment. I have been looking for it for some time with no luck".
And, of course, you know you are not going to find it. You assume 'crm' is a treatment or intervention and a comparative trial could then be set up to compare the subject group against a control. But CRM is nothing of the sort. CRM is no more than a recognition that there is more to safe commercial flying than simply being competent at manipulating aircraft controls. The weakness with CRM is that it has tried to be reductionist - but humans are too variable and the domain too broad.
