A formal theory characterizing various ways to combine individual beliefs into collective beliefs
What could it mean for a group to have beliefs over and above the beliefs of the individuals?
We ascribe beliefs in order to interpret actions/decisions based on reasons
Groups act and make decisions based on reasons, so it seems reasonable to think that we can ascribe beliefs to groups
The group beliefs are uniquely determined by the individuals’ beliefs, but it may not be identical to any of the individuals.
Example: condo asssociation where 50% believe \(A\) and 50% not \(A\). Maybe it’s reasonable to ascribe an indeterminate belief towards \(A\), but none of the individuals is indeterminate.
