Something rotten at the core of science?

The US Supreme Court has recently been wrestling with the issues of the acceptability and reliability of scientific evidence. In its judgement in the case of Daubert versus Merrell Dow, the Court attempted to set guidelines for US judges to follow when listening to scientific experts. Whether or not findings had been published in a peer-reviewed journal provided one important criterion. But in a key caveat, the Court emphasized that peer review might sometimes be flawed and therefore this criterion was not unequivocal evidence of validity or otherwise. A recent analysis of peer review adds to this controversy by identifying an alarming lack of correlation between reviewers' recommendations.
