Bandida schreef:Abstract:
The study tested the null hypothesis that if a horse is ridden in a snaffle bridle and then a crossunder bitless bridle, there will be no change in its behaviour. It was predicted that there would be change and that behaviour would improve when bitless. Four horses, none of which had ever been ridden in a crossunder bitless bridle, were ridden through two 4-min, exercise tests, first bitted then bitless. An independent judge marked the 27 phases of each test on a 10-point scale and comments and scores were recorded on a video soundtrack. The results refuted the null hypothesis and upheld the predictions. Mean score, when bitted, was 37%; and through the first 4 min of being bitless, 64%. A binomial probability distribution suggested that the results were significantly different from random effects. All 4 horses accepted the crossunder bitless bridle without hesitation. Further studies are warranted and it is hoped that others will build on this new field of investigation. The authors are of the opinion that the bit can be a welfare and safety problem for both horse and horseman. Equestrian organisations that currently mandate use of the bit for competitions are urged to review their rules.
Het accent ligt toch wel iets anders als wordt gesuggereerd in de beginpost, laat staan in vele van de reacties.
Verder vind ik het zelf ook niet indrukwekkend, maar dat het plaats vindt wel een boeiende ontwikkeling.
Ligt het accent iets anders? Laat ik een ander zinnetje dik drukken:

Lijkt mij toch een typisch gevalletje van een mening proberen te funderen dmv "onderzoek", en niet van een nul-hypothese testen om een mening te vormen. Ik heb het artikel niet gelezen en de filmpjes niet gezien. En met deze abstract lijkt mij dat ook helemaal niet nodig. En de geloofwaardige meningen die hier geuit zijn bevestigen deze indruk.
