In my previous post I referred to the East Anglia's CRU scandal. The WSJ summarizes damning evidence of unethical behavior in these extracts taken from the documents (a harsh editorial regarding the scandal is found here).
Let's be clear about it: what's in those documents isn't normal practice in science. There's too much bad blood and intellectual arrogance in there, mixed with an absence of personal detachment and a lack of commitment to scientific virtue.
Real scientists are dutifully skeptical. Real scientists refute bad arguments with good arguments and nothing else. Valid scientific theories stand on their own merits, they don't need the connivance, obfuscation and sanctimony that permeate those files.
