Scientists need to quit being advocates and just report their findings.
This. In spades and spades and spades and spades.
Then they can concentrate on defending methodology instead of spending time defending their philosophy, like that jackass Michael Mann does (hey, maybe he has a webcrawler and will stop by to sue me like he's suing everyone else).
Science is just as happy to be "wrong" as to be "right", since there is no "wrong" or "right" in science. Simply "is" or "is not". Gravity is not "right". Gravity "is". Doing something that doesn't pan out using sound scientific method means that you've likely eliminated that possibility and saved someone else some work. Many modern scientists, especially on the global warming front, have forgotten about the null hypothesis.
