[Perndog]

Picture this. X scientist at Y research facility has a medical hypothesis (a drug or a surgical procedure, you name it), but requires a living creature to test it and not just a petri dish.

If relevant aspects of an animal's physiology are similar enough to a human's, the scientist with an analytically trained mind will realize that he can perform a test on the animal and expect similar results on a human, thus eliminating the need for a human test subject, which would either be impossible of prohibitively expensive to acquire. Without the animal test subject, the experiment could never be performed at all, and any potential scientific gain from the experiment would be unattainable.

So explain how using an animal in an experiment automatically makes the hypothesis "poorly thought out," and tell me what "shifting through conclusions to gain insight into a problem" means. You may have meant "sift," but that still doesn't tell me much.
