Summary: [For the entire collection see Zbl 0659.00012.]
The formation of a group consensus probability distribution from the beliefs of its members has attracted much attention in the literature. Several procedures have been proposed, some on pragmatic grounds, others justified axiomatically. More fundamentally, the feasibility and desirability of such procedures have been discussed and several impossibility theorems proved. This paper surveys these contributions with particular regard to the context: why is such a consensus distribution needed.
