Scientific fraud is not new to us. It is not rare, but it is not common either. It happens at a frequency that's high enough to bother certainly people in the United States Congress, and probably others as well. But it is not frequent enough to declare that because the peer review system cannot reliably detect it, something has to be done about the peer review system. I think the peer review system is not quite fine, but absolutely the best thing we have.
