3. What is the course about? • Social Choice – the name captures all … and nothing. • It is about choice in society. • How Societies should choose. • How Societies could choose. • How societies can choose. • How Societies do choose. • It is an enormous topic and you are not expected to memorise all the detail in all its complexity. • We want you to get an overview. • Do not read and memorise … think and generalise.

4. The organisation of the course • We have some lectures. • We have some debates. • We have some experiments. • We have some discussions. • There is a problem in that there are lots of students on the course. • This creates organisational difficulties. • We are happy if the uncommitted students drop out. • We only want committed students who will take an active role and interact with us and the other students.

10. Lectures • All the lectures will be available via the site. • We recommend that you look at them both before and after the lectures… • … so that you come prepared. • You are not expected to memorise the lectures but instead understand the theme of the lectures and be able to take away general conclusions. • There will be some reading recommended but you are not expected to memorise the content.

11. The other activities: experiments, debates, discussions, exercise classes • With such a large number of students we are not quite sure yet how we are going to organise these other activities. • But we expect students to take an active role. • We may have to split up the group into smaller groups in some way. • We may run some experiments in the CESARE laboratory which is at Viale Pola. • We will be asking for volunteers to take part in the debates.

12. Assessment • We know that this is not important to you, but there are two methods of assessment: • A conventional examination. • Assessment by Group Project in which a self-appointed group of students write a project on a self-chosen topic approved by us. • Some titles from last year: • Berlusconi and Italian Politics: Why Italians Chose a Business Man Named Silvio Berlusconi? • Ill and Poor: Better it to be in the UK or in France? • Is it better to live in a dictatorship or in a democracy? • The Value of the Vote • Mind the Gap! How come Israel had a woman prime minister and Italy not (yet!)? • Social Order: How is social order sustained in human societies? • Voting Systems and Fairness: Two railway tracks: Parallel as in reality or converging as if seen in perspective? • In Sickness and in Health – better to be British or French? • If we decide to establish a new nation, which legal system would we choose?
