> One thing that might not be totally obvious from this article and others is that although some effects clearly replicate, and others do not, there are some effects that seem to be in a grey area, where the effects are probably real but much smaller than originally reported.

The two prior replication studies that I know of - the first was several years ago and raised the issue in the public mind afaik, then second maybe in the last year - both replicated almost all of the effects. The problems were that some effects were weaker than in the original studies. Are you saying that this most recent attempt at replication shows a large number of studies with no significant effects at all?
