 But is the group mind hypothesis explanatorily indispensable? If the rational behavior, representation, speech, etc. can easily be explained (or explained away) without invoking group minds, then the presumption of mindedness is defeated. Thus, if we discover of what appears to be a subject that its behavior was entirely controlled by or explicable in terms of the attitudes and behavior of some other (or others), then one would no longer have reason to think the subject in question as minded. For example, if the rational behavior of a group is explained wholly in terms of the individual members, then we are not tempted to think that the group itself is genuinely minded (Watkins 1957). Or, if there is a very tight fit between judgments and attitudes of the group on the one hand, and members on the other – for example if ascriptions of attitudes to a group just is a summary of ascriptions to its individual members (Quinton 1975–6) – then there is no reason to think of the group as having a mind of its own.
