I never said it was a new field, general_re. Think of it as an instantaneous combination of a vast number of consciousness events that are being coordinated and mediated by fields that have been well studied, such as EM and quantum fields. Whatever is going on in the group effect is using these fields to do it. I am not multiplying entities here.
You've added a field to the explanation of mob psychology, where no field was posited before. Well, you didn't, but the author above seems to be tending that way. Before I sign on to such a thing, I'd like to see why the field is the best possible explanation for the way people behave in groups, and therefore why it is necessary to postulate the existence of such a field in order to explain same. In a nutshell, what does having a field do for us that conventional psychological explanations about group dynamics do not?
