 Several responses have emerged to this problem. Velleman develops a solution that invokes interdependent conditional  intentions.[28]  Each individual conditionally settles what the group will do, where the condition is that each of the others has a similar commitment and intends likewise. Thus, I intend to J, on condition that you intend likewise. Some have worried that when intentions are interdependent in this way it’s not entirely clear that they settle anything at all, and hence, whether anyone is appropriately committed to our J-ing. If each intention is conditioned on the other, it’s just as reasonable to refrain from acting as it is to engage in it. For discussion, see Roth 2004, 373–80; Bacharach 2006, 137ff. Gilbert 2002, while addressing Robins 2002 and a precursor of Roth 2004 disavows the interdependent conditional view attributed to her by Velleman, Roth, and Robins. See also Gilbert 2003, 2009. Velleman himself is sensitive to something like this worry (1997a, 39) and it shapes how he formulates the content of the conditional  intention.[29]
