Expecting some undefined psi factor to change the behaviour of highly predictable large-scale physical systems such as computers is a completely different matter to positing that it might affect tiny quantum events which by their nature are unpredictable .

If Radin's experiments with the interferometer are to be believed, psi can affect fundamental particles. It doesn't seem a huge stretch of the imagination to cause a bit flip inside a DRAM chip and induce an actual "soft error" in a large-scale system.

If we want to consider even more "macro" PSI effects, distant healing would have to affect atoms, molecules and entire tissues to produce the claimed results. Not to mention poltergeists.

I don't know if there's a precise line that we can draw in terms of effect size, but maybe the folks at GCP have arbitrarily drawn one.
