** Background: ** Condorcet's Jury Theorem (1785) is an early application of probability theory in the social sciences. It provides a simple mathematical model that shows the advantages of broad pariciptation in societal decision making. The course will look at various models and theoretical results relating to collective decision making starting from Condorcet's jury
theorem and reaching current research on social networks and social choice theory. Special
interest will be given to modern approaches for quantitative analysis
and to computational efficiency. The basic questions relate to the
aggregation power of groups, to the power of individuals in
determining the outcome of a decision and understanding disagreement.

** Topics: ** The course will discuss two broad topics using involving different area of mathematics:
