RE: [RC] FW: Thought you might find this interesting - Kristen A Fisher

Great points. Also, what was the "test"?? I find it interesting to see that
this so-called 4 minute test was not described.

For all we know, it could have been a test to see if head tossing and
running away with the rider were increased.

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.

Caveat:  When I don't ride, I get argumentative  :)
