In the second paragraph of the quote the author ignores the whole point of replication efforts. We know that scientific studies may suffer from methodological errors. The whole point of replication studies are to identify methodological errors. If they disagree then you know there is an uncontrolled variable or methodological mistake in one or both of them, further studies and the credibility of the experimenters is then used to determine which result is more likely to be true. If the independent studies agree then it is evidence that they are both correct.

The author also argues that replication efforts are biased because they are mostly made by people who disagree with the original study. That seems like a valid point.

Specifying designs in advance is a good idea, though not orignal
