Re: [RC] FW: Thought you might find this interesting - Born CountryGotta admit, that type of test would have validity as to control! Can I watch? Gotta have no less than 10 horses for an accurate test. Esther and Chagalle, who never gets to gallop to the barn!

Not really. There were no control subjects. To be "scientific", the experiment should have had 16 horses, 4 that performed bitted twice, 4 that performed bitless twice, 4 that performed bitted, then bitless, and 4 that performed bitless, then bitted. That way you'd have a base line for bitted and bitless, an expected improvement due to simply repeating the exercises a second time, and the actual improvement (or lack thereof) when switching from bit to bitless and bitless to bit. There is also no way to determine how much of the result is due to the Hawthorne Effect, ie, that ANY change will produce a short term improvement in productivity. Often the requirement for a controlled situation may actually work against proving the validity of a hypothesis as it applies to the real world. In a controlled situation, such as the arena, an experiment may have a great deal of internal validity, ie, it works in the ring, but simultaneously lack external validity, as when you take the horse out on the trails. To compensate for this, the experiment should have included taking the 16 horses, half in bits and half bitless, 5 miles away from the barn, asking them to gallop towards said barn for 30 seconds and then asking them to halt USING ONLY THE REINS, no shift of weight or vocalization, measuring the time delay between asking for the halt and actually getting it.
