Well, Leigh, our entire world operates in the physical sense based on very few causal studies and millions, I'd guess, of experiential events by humans over thousands of years, and of course a great deal on studies that are only correlative ... but convincing nonethless.
I can't recall seeing a study that proves that water only runs downhill when you do not put hydraulic pressure behind it to force it to go uphill. Yet it's an accepted fact.
The only 'proof," that bits work, to my knowledge, is that they have used them for so long ... as though someone is waiting -hehehehe- just around the corner to show them the power and force of bitless (the hydraulics from my metaphor above) and that it works.
In other words, all the correlations that can be found in research are really (with humble respect to Cook who inspires us by his work) ineffectual in the real world you describe, but DOING IT AS A DEMONSTRATION is powerful.
I've done that for a very long time. Before during my early career with horses, where I often threw away bridles with bits and used either my hackamore or simple rope halters. I lost then not because I couldn't do it ... I most certainly could and did time and again ... but because everyone kept giving me special status (like the "Horsewhisperers" label nonsense) as though others could not do it. Each time I taught others to do it the same claim would be made. The student had to have been "special," and "hand picked" by me.
I think Dr. Cook is not going to have to labor on mostly alone, and I do not despair about those that know but will not show others. There are just too many examples out there of it being done. And more of us all the time willing to show others.
It's why I teach. Why I go and "evaluate," horses and insist that I can only test them with a halter or hackmore on them. Then the owners see it. The students see it too.
Some of us, not I of course
are just a bit too shy to share. However, there is more than one way to skin this particular cat.
I think the media might be one way.
