Depends on the problem. If the general human consensus believes the sun revolves around the earth, you're going to have a hard time working with multiple minds. Problems which require radical shifts in ideology are more than likely going to be tackled alone. It would come down to the maximum power principle. You would waste a significant amount of energy pulling someone psychologically one step in your direction, whereas independently, you could be three steps closer to proving your thesis. Not to mention, social cohesion, or whatever you want to call it, encourages group think and naturally ostracises outsiders as a primitive form of bonding or fitting in with one another.

Really hard problems fight monocultures of 'obvious truth' in the bonds of multiple minds.
