Of course that's just your theory of what would happen. So far as I know the
experiment has never been carried out and is beyond current technology.

So your theory is that the electromagnetic field has an ability to learn which
is not reflected in QED - it's some hitherto unknown aspect of the field and it
doesn't show up in the field violating Maxwell's equations or QED predictions?
And further this aspect of the EM field is able to effect behavior - at least
Apparently this aspect of the EM field is not affected by external fields;
otherwise thought processes would be affected by standing near power lines and
Van de Graf generators. It is essentially independent of EM fields as
described by known physics.
