 Greco’s account of knowledge transmission accommodates a strong notion of social epistemic dependence. This is because joint agency in general involves dependence among the cooperating actors to “do their part” in the cooperative activity. Moreover, as in other cases of joint action, the hearer has no guarantee that the speaker will prove dependable, no guarantee that the speaker will play their part well. Finally, we may note that much of the forgoing discussion about knowledge transmission can be extended to knowledge generation as well. That is, the production of knowledge can sometimes involve the kind of intentional cooperation that characterizes joint activity. For example, we can conceive of a research team that cooperates in an investigation that is too complicated for any one person to undertake alone. If that cooperation is structured in the right way, and if the knowledge so produced is attributable to that cooperation, we will have cases in which the production of knowledge is a joint achievement.
