Ben Goldacre has not dismissed anything out of hand, he has asked for some proof.
If someone can pass a rigorous blind test that would be proof. This request has been made for years on all sorts of hifi trickery and to date no one has passed. In fact very very few actually try, then tend to cry off.

So I dont think Mr Goldacre has asked anything that hasnt been asked before.

Could you provide some links or references to the measurements you mention as I would be very interested to read them.
Thanks
