Wolfgang, I am not arguing for it one way or another, I was just mentioning that there ARE studies, and if people want to look for them they can do so, more productively probably than to ask for them or to summarize them here. Except for music, people seem to me not to come here to learn about a thing, just to argue from the positions they already hold. If people wish to learn they can search and find a variety of views, studies, and discussions among people of (possibly) calmer minds.

My main point was that this approach (getting people into arguments here at Mudcat) is not a good basis on which to discuss (or change) what needs to change in our world.
