Electoral systems can be seen not only as ways to constitute governing bodies but also as mechanisms for conflict management within a society. Some systems, in some circumstances, will encourage parties to make inclusive appeals for electoral support outside their own core vote base; for instance, even if a party draws its support primarily from black voters, a particular electoral system may give it the incentive to appeal also to white, or other, voters. Thus, the party’s policy platform would come less divisive and exclusionary, and more unifying and inclusive. Similar electoral system incentives might make parties less ethnically, regionally, linguistically or ideologically exclusive. Examples of how different electoral systems have worked as tools of conflict management are given throughout this text.
On the other side of the coin, electoral systems can encourage voters to look outside their own group and think of voting for parties which traditionally have represented a different group. Such voting behaviour breeds accommodation and community building. Systems which give the voter more than one vote or allow the voter to order candidates preferentially provide the space for voters to cut across preconceived social boundaries. At the 1998 Good Friday agreement election in Northern Ireland, for instance, vote transfers under the STV system benefited ‘pro-peace’ parties while still providing broadly proportional outcomes. At the 2003 election, however, a shift in first-preference votes towards hard-line parties tended to outweigh such effects.
