So give a few examples. I'm not aware of any time a CRIDer has uncovered scientific error, much less fraud.
For that matter, I'm unaware of anytime a CRIDer has called out a fellow CRIDer on error or fraud, eg: doctored quotes, conveniently forgetting counterexamples, misapplying the laws of thermodynamics (actually AiG has disowned that one, finally)
Scientists are no better than anyone else, no more moral. No halo with that white coat, just the same doom to frailty and failure.
As I said, the chances of detection, and the severity of punishment, act as a deterrence.
