 One worry with this argument concerns how the premise-driven decision procedure is implemented. If it’s simply implemented by virtue of the intentions of each individual to establish and maintain rationality at the group level, then there appears to be an alternative to the group mind hypothesis. That the group appears to have a mind of its own in examples such as this would then be an artifact of the restricted focus of the example, which said nothing about how a policy of rationality at the collective level is maintained. Once we broaden our perspective to recognize that each individual aims to maintain rationality at the collective level, it’s no longer clear that there is such a gap or discontinuity between the intentionality at the level of the individuals and of the group. Thus, there would be no warrant for talk of group  minds.[39]  Of course, this criticism makes strong assumptions about how to explain any rationality that might be exhibited at the group level, assumptions that are open to challenge.
