I'm not knocking science. Something is good until it is not...
James, science is a process of discovery. I am not sure you are talking about the process, or the results of various experiments and inquiries.
If you can come up with a better research method and design, let me and the world know.
If you want to question the results - that is acceptable - and encouraged. Just be prepared to justify your questions with an alternative hypothesis.
Debating scientific discovery is fun and actually moves research forward.
